The error usually occurs while accessing the network for updating or installing.

At Bobcares, we often get requests from our customers to fix the error network is unreachable as part of our Server Management Services.

Today, let’s get into the details on how our Support Engineers fix this problem.

What causes apt-get connect (101 network is unreachable)?

The error mainly occurs due to problems in network connections.

This error indicates that either the IPv6 connection is unstable, or the servers are dead, or the file is not found.

For instance, the error appears as follows.

Let’s see how our Support Engineers help the customer to fix this.

Easy way to fix the error

At Bobcares, where we have more than a decade of expertise in managing servers, we see many customers face error apt-get connect (101 network is unreachable).

Now, let’s see the major reasons and how our Support Engineers fix this error.

Disabling ipv6

Recently one of the customers was getting Update information outdated alert then he applied sudo apt-get update command. Unfortunately, the user got stuck with this error.

On further analysis, we could trace from the logs that the user’s machine was using IPv6 to connect to the internet.

Hence, the reason behind the error was user’s internet service provider does not support IPv6. So we tried disabling IPv6.

To do this system-wide, we edited the file /etc/default/grub by running the below command

sudo nano /etc/default/grub

And added the following.

ipv6.disable=1

To the value of GRUB_CMDLINE_LINUX_DEFAULT.

In a default Ubuntu installation, that line reads

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

so we changed it to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable=1"

Then, we ran the following command.

sudo update-grub

Finally, we rebooted the server.

Finally, the connection problem was then resolved.

Enabling secure port

In addition, in certain cases this error results due to closed port 443.

We then open the secure port and the error get disappeared.

[Having trouble with this error? We’ll fix it for you.]

Conclusion

In short, apt-get connect (101 network is unreachable) occurs due to problems in network connection. Today, we saw how our Support Engineers helped the customer in fixing the error.

Ubuntu 8

In this article, we will explore how to fix the “Error 101: Network is Unreachable” issue when updating Ubuntu using the Advanced Package Tool (APT). This error is typically indicative of a network connection issue or a problem with the network configuration.

To fix the «Error 101: Network is Unreachable» when updating Ubuntu with APT, you can try changing the repository mirror to the ‘Main server’ or disabling IPv6 system-wide. These solutions should help resolve the issue and allow you to update your system successfully.

Understanding the Error
Solution 1: Changing the Repository Mirror
Solution 2: Disabling IPv6
Conclusion

Understanding the Error

The “Error 101: Network is Unreachable” is a common error that users encounter when trying to update Ubuntu using the apt-get update command. This error is usually a sign that your system is unable to establish a connection with the network, which could be due to a variety of reasons, such as an issue with your local repository mirror or a problem with your Internet Service Provider (ISP).

Solution 1: Changing the Repository Mirror

One of the simplest solutions to this problem is to change the repository to the ‘Main server’. Sometimes, local repository mirrors can experience downtime, causing the “Network is unreachable” error.

To change the repository mirror, follow these steps:

Open ‘Software & Updates’ on your Ubuntu system.
In the ‘Ubuntu Software’ tab, locate the ‘Download from’ dropdown menu.
Change the selected option to ‘Main server’.
Close the window and try running sudo apt-get update again.

This change should force your system to use the main Ubuntu repository, which is generally more reliable.

Solution 2: Disabling IPv6

Another potential cause of this error is that your machine is using IPv6 to connect to the internet, but your ISP does not support IPv6. In this case, you can disable IPv6 system-wide.

To disable IPv6, you need to edit the /etc/default/grub file and add ipv6.disable=1 to the value of GRUB_CMDLINE_LINUX_DEFAULT. Here’s how you do it:

Open the terminal and type sudo nano /etc/default/grub. This command opens the grub file in the nano editor.
Locate the line that reads GRUB_CMDLINE_LINUX_DEFAULT and add ipv6.disable=1 to it. It should look something like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable=1"
Save and exit the file by pressing Ctrl+X, then Y, and finally Enter.
Run sudo update-grub. This command updates the grub and applies the changes you made.
Reboot your system.

Disabling IPv6 might seem like an extreme solution, but if you’re also experiencing issues browsing the web, it might be necessary.

Conclusion

The “Error 101: Network is Unreachable” when updating Ubuntu with APT can be a nuisance, but it’s generally easy to fix. By changing the repository mirror or disabling IPv6, you should be able to resolve the issue and update your system successfully. If you’re still experiencing problems, it might be worth reaching out to your ISP to see if there are any known issues or contacting Ubuntu support for further assistance.

APT stands for Advanced Package Tool. It is a package management system used in Ubuntu and other Debian-based Linux distributions to handle the installation, removal, and updating of software packages.

To update the grub after making changes to the /etc/default/grub file, you can run the command sudo update-grub in the terminal. This command updates the grub configuration and applies the changes you made.

Disabling IPv6 might be necessary if you’re experiencing network connectivity issues or if your ISP does not support IPv6. It can help troubleshoot network-related problems and ensure compatibility with IPv4-only networks.

To get further assistance from Ubuntu support, you can visit their official website at https://ubuntu.com/support. They provide various support options, including community forums, documentation, and professional support services.

Have you tried changing the repository to the ‘Main server’?

You can change it by opening ‘Software & Updates’ and selecting a different mirror.

From time to time the local repository mirrors go down so its always a good idea to check other ones

I have also noticed that it is trying to connect via IPv6 which your router or ISP may not support. Have you tried this?

Из журналов кажется, что ваша машина использует IPv6 для подключения к Интернету. Возможно, ваш провайдер интернет-услуг не поддерживает IPv6. Вы можете попробовать отключить IPv6.

Чтобы сделать это в общесистемной, отредактируйте файл /etc/default/grub (например, используя sudo nano /etc/default/grub) и добавив ipv6.disable=1 к значению GRUB_CMDLINE_LINUX_DEFAULT.

В установке Ubuntu по умолчанию эта строка читает

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

, поэтому вы меняете ее на

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable"

. Затем сначала запустите sudo update-grub, затем перезагрузитесь. [ ! d4]

Just in case someone has similar problem — in my case, there was a problem with my network. I did have internet access, but the adapter was not configured properly. Once I switched to wifi adapter, the apt update ran smoothly.

Disabling IPv6 because of a single networking issue seems a little overkill.
@DavidFoerster agree, but since poster wasn’t able to browse the web either, I reckoned that only forcing APT on IPv4 wouldn’t cut it.
Good point I originally understood the part about browsing to mean the opposite since it’s stated so weirdly.

Если вы получаете такие ошибки, это означает, что либо ваше IPv6-соединение было нестабильным, либо серверы были мертвы, либо файл не был найден. Прямо сейчас прорабатывается:

Измените настройки сетевого прокси-сервера синхронно с тем, который вы используете для доступа к этой веб-странице (короче говоря, прокси вашего браузера)

То, что вы видите в выходных данных, — это то, что ваша машина пытается подключиться с использованием адресов IPV6 (например, 2001: 67c: 1562 :: 13), которые отличаются от адресов IPv4 (например, 192.168.0.1). Вы могли бы иметь два подхода здесь. Один — отключите IPv6, выполнив эти шаги:

Откройте /etc/sysctl.conf в любом текстовом редакторе (для этого вам понадобится sudo). Лично я бы сделал что-то вроде sudo nano /etc/sysctl.conf (nano проще всего) или sudo vi /etc/sysctl.conf.

добавить эти строки

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Выполнить sudo sysctl --load, чтобы применить изменения

Вторым способом будет использовать IPv6 DNS. Например, нажмите на индикатор сети на верхней панели, выберите Edit Connections, и для вашего конкретного соединения Wi-Fi или Ethernet используйте 2620:0:ccc::2 DNS, который OpenDNS IPv6-сервер . Убедитесь, что вы выбрали опцию «Только адрес»

Подскажите в чем может быть проблема?

А как себя ведёт браузер: HTTPS сайты открываются, а HTTP нет? А с 2,4 гигигерцовой сети проблема наблюдается?
Тот же http://archive.ubuntu.com к примеру. И как ведут себя устройства, подключенные к этой же ТД (если не ошибаюсь — онушка от ростелекома?)

garmayev

А как себя ведёт браузер: HTTPS сайты открываются, а HTTP нет?

Именно так, сайты http — сервер не отвечает, https — нормально работают

И как ведут себя устройства, подключенные к этой же ТД (если не ошибаюсь — онушка от ростелекома?)

Да, Ростелеком.

Другие устртойства в сетиведут себя адекватно — т.е. штатно открывают и http, и https, поэтому я предполагаю, что это что-то у меня в бубунте

Ничего не происходит просто так…

c47

Ну тогда я даже не знаю, что предложить. Кроме одного: попробуйте подключить инет системк другим путём: хоть с телефона 3/4g раздать по usb или по wifi, чтобы уже точно исключить ТД из списка подозреваемых. Если и так не получится — «ну в этой ситуации мы просто наше это самое мы уже здесь наши полномочия всё, окончены»

garmayev

Мдяаа, вот совсем забыл, что сеть еще можно с помощью проводов проевти…

Через провод соединение идет нормально, что по https, что по http.

Делаю вывод, что виновник этой пор**графии — все-таки вафля.

Как по-вашему, в чем беда, я уже половину мозга высушил, вторая боится такой же участи, а третья половина думать вообще не хочет…

Ничего не происходит просто так…

c47

мне онушки с подозрениями на разные баги приносят регулярно (я о операторе одном работаю, мы gpon/gepon в т.ч. предоставляем).
Баги у них в основном хардовые: битые порты, окисленные платы, вздутые кондёры, искарёженные адаптеры или слетела прошивка. но подобных проблем даже не припомню.

Через провод соединение идет нормально, что по https, что по http.

надо сначала максимально сузить число подозреваемых — напишите как всё-таки инет получили?
с другого устройства
или к этой же онушке по eth подключили?

если по eth от ONU проблема есть — то виноват либо оператор, либо сама онушка, попросите рт сбросить её в дефолт, а то мало ли, я не знаю как у них где сети работают, может нет в вашем регионе acs-сервера, и придётся её настраивать самому потом

если по eth проблемы нет, то из списка подозреваемых уходит рт, но подтягивается wifi ноута либо 5ггц wifi онушки (файервол я практически исключаю, в свежеустановленной системе по дефолту всё открыто, но всё же гляньте правила, чем черт не шутит)

и попробуйте всё-таки подключиться к 2,4ггц диапазону этой же онушки и если проблемы в 2.4 не повторится, то попробовать другую 5ггц точку доступа найти и с неё проверить

garmayev

Подозреваемые:
1. Точка Доступа (aka Роутер)
2. Адаптер Wifi (На уровне железа)
3. Настройки Wifi (На программном уровне)
4. Файрволл
5. Драйвер Wifi

Расследование:
1.1. Роутер раздает 2 сети вайвай: 2.4G и 5G
1.2. Подключаю мобильник к ЛЮБОЙ сети — все сайты открываются
1.3. Подключил ноутбук к сети через провод к роутеру — все работает (и http, и https)

Отсюда: Подозреваемый «Роутер» из списка исключен

2. На уровне железа как может рубиться соединение ТОЛЬКО на 80 порт? Тут, как говориться, «Меня терзают смутные сомнения»

4. Файрвол

$ sudo ufw status verbose [sudo] пароль для garmayev: [s]Никто не знает мой пароль[/s] Состояние: неактивен
Отсюда: Подозреваемый «Файрвол» из списка исключен

5. Драйвер я переустановил (качнул с github по этой инструкции https://askubuntu.com/questions/994555/qualcomm-atheros-device-168c0042-rev-31-wi-fi-driver-installation)

Отсюда: Подозреваемый «Драйвер» из списка исключен

Итого, как я понимаю, у меня что-то с конфигами сети не так, а вот что и где — ХБЗ

P.S. Для модераторов — ХБЗ = Хто Бы Знал (не мат, на всякий случай)

Ничего не происходит просто так…

Всё-таки попробуйте обозвать 2.4 и 5ггцовые вафли разными ssid-ами и подключиться именно к 2.4, разные чудеса бывают на белом свете))

нет, возможно несовместимость знаков зодиака конкретных радиомодулей роутера и ноутбука, я слышал о таком где-то, не вспомню уже…
sudo apt install mtr-tiny ### консольная, удобная штука, не путать с гуёвым аналогом — mtr, в нём функционала 0 (или я дурак)
mtr-tiny — плод любви ping и traceroute, обладает основным функционалом мамы и папы, мне по работе он особо не нужен, но иногда пригождается, поэтому о его возможностях я сужу лишь по странице man, впечатляет

ага, значит до тех же ipv4 адресов связь по icmp есть, а по 80 порту нет? да, девки пляшут всё интереснее и выкрутаснее.
Можно чисто в качестве эксперимента накатить на ноут 10ку свеженькую, (если есть пара часов свободного времени) если и на ней проблема повторится — то звёзды так сошлись хардварная несовметимость, других вариантов у меня нет, а если на винде всё будет работать — то значит линуксовые дрова на конкретный радио-модуль всё-таки неайс

[all variants] mount error(101): Network is unreachable

mount error(101): Network is unreachable

I am running Lucid 64bit. I have noticed that when booting I get the following errors when mounting cifs volumes during the boot process.

from boot.log:

mount error(101): Network is unreachable
Refer to the mount.cifs( 8 ) manual page (e.g. man mount.cifs)

Refer to the mount.cifs( 8 ) manual page (e.g. man mount.cifs)

mountall: mount /media/misc [932] terminated with status 32
mountall: mount /media/music [933] terminated with status 32
mountall: mount /media/fs_files [934] terminated with status 32

they do mount but this error pauses the boot process for 10 or 15 seconds.

My assumption is that an attempt is made to mount the drives before the network is available.

Here’s my fstab:

Use the _netdev option:

Re: mount error(101): Network is unreachable

Worked for me. On my system, WICD is now started, the wireless connection is made, and the shares are mounted. Thank you for the help!

Re: mount error(101): Network is unreachable

I had this same problem after upgrading to Lucid and as I didn’t find a solution, I used the /etc/rc.local script as workaround:

Code:

#!/bin/sh 
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
mount -t cifs -o iocharset=utf8,user=myuser,password=mypwd,rw,uid=myuid,_netdev //server/share /mount/point

exit 0

Hope this helps

Re: mount error(101): Network is unreachable

Hi,

I’d Like to revive this thread.

I am getting the error described here even with the _netdev option under ubuntu 10.04

As renardeau said you can add these to the rc.local file which stops the error.

My issue is that one of my mounts in my case is used for configs for vairous applications like SABNZBD + Sickbeard and using the rc.local method means that I cant use these applications as services. However the error(101) causes issuses with these applications on boot, as the mount is not available when the services are starting.

Does anyone have any more suggestions? I am thinking of trying a different version.
Re: mount error(101): Network is unreachable

Ok so i have tried this on a few different versions now, 11.10 server and desktop. Both with the same issue. Its really strange.

For me it means that I have to directly mount a native drive in order to use it as a ‘Install disk’. Shame really

does anyone have any other ideas?

Hi guys
Just been experimenting with OpenVPN for a small company network. I have been trying to establish a bridge connection so that users outside of the network can connect to machines in the network.

The OpenVPN server is a Linux machine with one NIC and my test client is a Windows 7 machine. I have been able to successfully establish a single connection directly to the server.

I have been following this http://openvpn.net/index.php/open-sourc … dging.html tutorial to create a bridge so I can connect to other machines on the network.

The IP of the server on the local network is 192.168.2.252, the networks DHCP server and internet gateway is 192.168.2.254.

When I try to connect the the OpenVPN server I eventually get this message repeatedly:
Tue Sep 13 16:40:37 2011 us=216236 212.183.128.38:6711 write UDPv4 []: Network is unreachable (code=101)

For some reason I have an error while running this code:

OS is Ubuntu 20.04. My code runs perfectly on the other machine, so the problem is obviously somewhere with the machine.

I’ve tried:

sudo ufw allow 465/tcp

Also I installed and run postfix mail server and added this to /etc/postfix/main.cf:

smtps     inet  n       -       y       -       -       smtpd
  -o syslog_name=postfix/smtps
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject
  -o content_filter=smtp-amavis:[127.0.0.1]:10026

and then restarted postfix with

sudo systemctl restart postfix

But nothing solved the problem. Please help me with this error.

The error mount error(101): Network is unreachable means that you attempted the mount before the network came up.

To fix this, add the _netdev option to your /etc/fstab CIFS entry. _netdev means to delay the mount until your network is connected.

Your /etc/fstab line should look like this:

//192.168.0.100/Volume_1 /mnt/vol1 credentials=/home/user/my-sys/.user,iocharset=utf8,file_mode=0775,dir_mode=0775,_netdev 0 0

To continue using /etc/rc.local for your mount, you’ll need to set up a new job (to prevent blocking) that loops until the network is up.

From this answer in Ask Ubuntu:

(
until ping -nq -c3 W.X.Y.Z; do
   # Waiting for network
   sleep 1
done
mount -t cifs -o credentials=/home/user/my-sys/.user,iocharset=utf8,file_mode=0775,dir_mode=0775 //192.168.0.100/Volume_1 /mnt/vol1
)&

Replace W.X.Y.Z with an IP address that responds to ICMP requests, like your router gateway.

Всем привет.
Есть проблема. В сети крутится samba сервер (192.168.0.251)
На пользовательской машине установлен Alt Linux 5.0 Ковчег. В файле fstab добавлена строка:
//192.168.0.251/pomoyka /mnt/file cifs credentials=/mnt/file2,rw,noperm,iocharset=utf8,forcemand 0 0

При загрузке компа, автоматически samba не монтируется. Вручную (mount /mnt/file) монтируется «на ура».
Network Manager service стартует до попытки монтирования. Параметр _netdev не помогает.

В Alt Linux 4.1.1 такой проблемы не было.
Хелп. Заранее благодарен за помощь!

Поищите на форуме — Skull уже отвечал на аналогичный вопрос. Там надо добавить специальную опцию. Какую — не помню.

Искал. Не нашёл.
Чтоб скучно сообществу не было, расскажу об ещё одном баге.
При монтировании samba’ы в Alt Linux’e 4.0 вышеуказанным способом и работе с документами по сети в Openoffice’e 2.4 всё работало прекрасно.
После обновления до Alt Linux 4.1.1 в OpenOffice’e 3.0 стали наблюдаться интересные глюки. Если я на samba’вой шаре, в примонтированной папке создаю в 3-м OO документ и сохраняю его, то потом он открывается только для чтения. Но если я создаю ссылку на рабочем столе на этот документ, всё нормально редактируется. В 2.x и в 3.1.1 OO всё работает без проблем.

Re: mount error(101): Network is unreachable

Worked for me. On my system, WICD is now started, the wireless connection is made, and the shares are mounted. Thank you for the help!

Re: mount error(101): Network is unreachable

I had this same problem after upgrading to Lucid and as I didn’t find a solution, I used the /etc/rc.local script as workaround:

Code:

#!/bin/sh 
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
mount -t cifs -o iocharset=utf8,user=myuser,password=mypwd,rw,uid=myuid,_netdev //server/share /mount/point

exit 0

Hope this helps

Re: mount error(101): Network is unreachable

Hi,

I’d Like to revive this thread.

I am getting the error described here even with the _netdev option under ubuntu 10.04

As renardeau said you can add these to the rc.local file which stops the error.

My issue is that one of my mounts in my case is used for configs for vairous applications like SABNZBD + Sickbeard and using the rc.local method means that I cant use these applications as services. However the error(101) causes issuses with these applications on boot, as the mount is not available when the services are starting.

Does anyone have any more suggestions? I am thinking of trying a different version.
Re: mount error(101): Network is unreachable

Ok so i have tried this on a few different versions now, 11.10 server and desktop. Both with the same issue. Its really strange.

For me it means that I have to directly mount a native drive in order to use it as a ‘Install disk’. Shame really

does anyone have any other ideas?

On a newish 18.04 system, I added a few SMB mounts to my fstab and verified they do mount, interactively.

When my system boots, it complains about CIFS mount errors, then tells me I am in emergency mode and proceeds to cloud-init (eventually obtaining an IP address, I think). If I bypass the emergency mount, I find my mounts to have been mounted no problem, probably after it obtained an IP)

Would love some advice as I’d like for this machine to boot unattended.

I have attached a screenshot and various excerpt of my journalctl -b
log that seem relevant.

Подскажите, кто знает, такую вещь.

Есть сервер в сети с samba, есть centos 7 рабочие станции, которые монтируют с него шары. Монтирование осуществляется посредством systemd, вот таким вот юнитом:

mnt-public.mount

[Unit]
Description=cifs mount script
Requires=network-online.target
After=network-online.service
[Mount]
What=//10.67.124.1/public
Where=/mnt/public
Options=username=nobody@r05,password=1,sec=ntlm,noperm
Type=cifs
[Install]
WantedBy=multi-user.target

И всё это успешно работает, практически на всех станциях, но есть несколько «фирменных» машин HP, с которыми это не катит,
типа на момент выполнения монтирования — сети нет!

Собственно вопрос, как победить данную проблему? На не HP станциях в этой же сети с аналогичной версией ОС и настройкой — всё ОК.
И попутно вопросик, можно ли решить проблему перемонтирования шары при пропадании «сети» в рамках юнита монтирования? Т.е. комутатор выключили-включили, всё, шара отвалилась и пока не перезагрузишься, повторно она не перемонтируется при «возобновлении» физического линка.

[SOLVED] — Cannot automount Samba share from fstab

Hi guys, I successfully got Samba working on my home serv last night but for some reason I cannot seem to automount the share at boot time (native systemd)

/etc/fstab

# kphmsrv /mnt/Files  Samba
//kphmsrv/Files /mnt/Files cifs users,username=kaipee,password={mypassword},workgroup=WORKGROUP,ip=192.168.0.10 0 0

errors.log

Sep 30 14:03:02 zoostorm-arch kernel: [    8.721292] CIFS VFS: Error connecting to socket. Aborting operation
Sep 30 14:03:02 zoostorm-arch kernel: [    8.721956] CIFS VFS: cifs_mount failed w/return code = -101

I thought systemd wouldn’t attempt mounting until network was up?

I have removed both noauto (as I did want to automount at boot) and noatime (as I read that it causes issues when mounting at boot)

Re: [SOLVED] — Cannot automount Samba share from fstab

OK so I think I have narrowed it down to the network not being connected.

My current /etc/fstab

# kphmsrv /mnt/Files  Samba
//kphmsrv/Files /mnt/Files cifs _netdev,users,username=kaipee,password={mypassword},workgroup=WORKGROUP,ip=192.168.0.10 0 0

Booting shows failed for a dependency.
Error log shows:

Sep 30 15:22:28 zoostorm-arch kernel: [ 1023.268131] CIFS VFS: default security mechanism requested.  The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel release 3.3
Sep 30 16:24:39 zoostorm-arch kernel: [   10.125967] CIFS VFS: Error connecting to socket. Aborting operation
Sep 30 16:24:39 zoostorm-arch kernel: [   10.126602] CIFS VFS: cifs_mount failed w/return code = -101

Upon login I can mount the share, however if I disable my wireless connection and try to mount I get:

[kaipee@zoostorm-arch ~]$ mount /mnt/Files
mount error(101): Network is unreachable
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

…and the same error occurs:

Sep 30 15:33:04 zoostorm-arch kernel: [  515.431106] CIFS VFS: default security mechanism requested.  The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel release 3.3
Sep 30 15:33:33 zoostorm-arch kernel: [  544.010324] CIFS VFS: Error connecting to socket. Aborting operation
Sep 30 15:33:33 zoostorm-arch kernel: [  544.010406] CIFS VFS: cifs_mount failed w/return code = -10

So it does indeed look like it won’t mount at boot because of no network connection — however I have included the _netdev option and I am using systemd which is supposed to not attempt mounting until network is available ??

Re: [SOLVED] — Cannot automount Samba share from fstab

I just don’t get what is happening here. I have updated my /etc/fstab to read:

//192.168.0.10/Files /mnt/Files cifs x-systemd.device-timeout=60s,users,username=kaipee,password={mypassword},workgroup=WORKGROUP,ip=192.168.0.10 0 0

…forcing systemd to wait for at least 60 seconds to mount the share. My machine boots and logs in with a working connection in about 15 seconds after initial loading.

https://lh4.googleusercontent.com/-DOTi … 0409_6.jpg

Yet it still complains that the network is not available and is clearly ignoring the options about timeout and _netdev ??!

Re: [SOLVED] — Cannot automount Samba share from fstab

_netdev only works if you have proper activation of network.target. How are you establishing a network connection?

Alternatively, just use an automounter on the share and let it be mounted on first access — add noauto,x-systemd.automount to the options.

Re: [SOLVED] — Cannot automount Samba share from fstab

Hi falconindy,

I’m connecting to a wireless network with WPA2 (WUSBN v2) using the NetworkManager service. How do I configure/check this network.target?

Re: [SOLVED] — Cannot automount Samba share from fstab

NetworkManager-wait-online.service should activate network.target. You’re still better off using an automount unit.

Re: [SOLVED] — Cannot automount Samba share from fstab

How does the automount unit work?
I have a few applications and services that use the samba share/mount so kind of want it always mounted.

Re: [SOLVED] — Cannot automount Samba share from fstab

Automount means its… mounted automatically on first access.

Re: [SOLVED] — Cannot automount Samba share from fstab

I was leaning more towards are there any benefits of this over mounting at boot?
Is it configured for every user automatically? Is it mounted by user or root?

Why is an automount unit better than automatically mounting during boot?

Sure. You don’t have to worry about when the network comes up.

kaipee wrote:

It’s mounted by root according to the options in fstab. It’s exactly the same as if you were insisting it mount on boot.

kaipee wrote:

Boot won’t explicitly hang waiting for this to mount — only for the automount to be initialized on the mountpoint.

Re: [SOLVED] — Cannot automount Samba share from fstab

But I kind of want boot to hang — at least until the network comes up and continues to mount the share

kaipee: Member; From: Belfast, UK; Registered: 2012-07-07; Posts: 214

Re: [SOLVED] — Cannot automount Samba share from fstab

…does the automount launch a ‘daemon’ of sorts, running in the background and waiting for a working network connection before initializing the mount? Allowing the rest of the system to function normally, and mounting the share as soon as a valid connection is confirmed?

Re: [SOLVED] — Cannot automount Samba share from fstab

Again, it mounts on first access by you (or will just fail if the endpoint is unreachable). I suggest trying this and seeing how it works before asking the same question again.

Re: [SOLVED] — Cannot automount Samba share from fstab

I gotta admit I was dead set against the automount solution when I read the suggestion but it works beautifully. Hardly any lag at all on first time access and no hanging issues (so far). Thanks, falconindy.

EDIT: Spoke too soon. This thread is marked solved, so I won’t bring up my issues here. Started a new thread instead. Apologies for the mess.

Re: [SOLVED] — Cannot automount Samba share from fstab

Just passing by to mention that the entry that turned out to work for @kaipee contains auto, non noauto as @falconindy suggested. And indeed, this works for me too.

1 made 2 edits to my own existing lines:
remove _netdev
replace noauto by auto

Doesn’t make too much sense to me, but it works

Hi, I have issue with auto mounting samba shares. Shares aren’t mounted on boot, but I can mount them manually by run «mount -a». It’s possible that openrc try to mount shares before connecting to network?

/etc/fstab

Code:

//dedyk/transmission /media/lekto/transmission cifs vers=3.0,credentials=/root/.credentials 0 0

//dedyk/backup /media/lekto/backup cifs vers=3.0,credentials=/root/.credentials 0 0

/var/log/rc.log

Code:

* Mounting network filesystems …

mount error(101): Network is unreachable

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

mount error(101): Network is unreachable

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

* Could not mount all network filesystems

dmesg

Code:

Those shares are (attempted to) mount on boot, which is your problem. You did not mark them as _netdev, so localmount attempts to mount them, which fails because localmount runs before the network is started. You should mark them as _netdev to prevent mounting them before the network starts. You may also need to follow Ant P.’s instructions to get them to mount once network is available.

I edited netmount and added _netdev, but it sometimes worked and sometimes not. Then I haved realized I forgot to run net.eth0 and after fix it samba shares work well.

I’m writing here because this doesn’t work anymore for me after switching network management to dhcpcd [1]. I had problem with dhcpcd that it was taking too long to get network configuration, which was delaying start of xdm. Now there is no delay during boot, but network starts working few seconds after start of xfce and samba shares are not mounted.

I got this in dmesg:

Code:

[ 22.517890] CIFS: Attempting to mount //dedyk/transmission

[ 22.517920] CIFS: VFS: Error connecting to socket. Aborting operation.

/etc/conf.d/netmount:

Code:

/etc/fstab:

Ok, I kludged it, in /etc/init.d/netmount I added in depend():

Code:

after xdm

and in start():

Code:

ebegin «Waiting for network connection»

for i in `seq 30`; do

echo -n «.»

sleep 1

ping -c1 192.168.0.1 &>> /dev/null

if [ «$?» == «0» ]; then

ebegin «Network seems to work»

break

done

Well, sometime after my last post that method stopped working. Recently I came up with this:

Code:

#!/bin/sh

function loop {

local program_name=»delayed-mounter»

for i in $(awk ‘/cifs/ {print $2}’ /etc/fstab); do

echo $program_name: trying to mount $i > /dev/kmsg

while [ -z «$(mount | grep $i)» ]; do

mount $i

sleep 5

done

echo $program_name: $i is mounted, continue > /dev/kmsg

done

echo $program_name: everything was mounted, exiting > /dev/kmsg

}

loop&

To use it put it in /etc/local.d/delayed-mounter.start, give it execute permission and add local to default runlevel. This script is looking for line with cifs in /etc/fstab in second column and trying to mount it one by one until it was successfully mounted. There are some improvements that can be added:

— Ignoring lines that are comments (starts with «#»),

— It trying to mount share until it’s mounted, so it can stuck. It could be fixed by creating separate thread for every mount,

— Checking it share was mounted properly could be better.

That script will mount any line that has cifs anywhere in it:

Code:

$ printf ‘The scifs are here.n’ | awk ‘/cifs/ {print $2}’

scifs

$ printf ‘Open the door; the scifs are here.n’ | awk ‘/cifs/ {print $2}’

the

Polling like that is generally bad. Why not use a dhcpcd hook to mount the filesystems after the network is up? Add noauto to the mount options. Create a dhcpcd hook in /lib/dhcpcd/dhcpcd-hooks. The example in /usr/share/dhcpcd/hooks/29-lookup-hostname looks like a good starting point. When the interface is brought up, bring up all the cifs filesystems, which you can more cleanly list using findmnt:

Code:

findmnt —fstab -t cifs —output TARGET —noheadings

В установке Ubuntu по умолчанию эта строка читает

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

, поэтому вы меняете ее на

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable"

. Затем сначала запустите sudo update-grub, затем перезагрузитесь. [ ! d4]
