This article mainly explains the repair method tutorial of "X11 forwarding request failed on channel 0" in Linux. Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn the "X11 forwarding request failed on channel 0 repair method tutorial in Linux".

First of all, let's assume that you have correctly enabled X11 forwarding for SSH.

If you encounter "X11 forwarding request failed on channel 0" when logging in (X11 forwarding request fails on channel 0), there may be different reasons and different solutions.

Option one

For security reasons, the OpenSSH service binds the X11 forwarding request to the local loopback address by default and sets the hostname to "localhost" in the DISPLAY environment variable. Under this setting, some X11 clients do not handle X11 forwarding correctly, which can lead to errors in the report. To solve this problem, add the following lines to the / etc/ssh/sshd configuration file, which binds the X11 forwarding request to the address of the foreign network card.

$sudo vi / etc/ssh/sshd_configX11Forwarding yesX11UseLocalhost no

Restart SSH to make the settings take effect:

$sudo / etc/init.d/ssh restart (Debian 6, Ubuntu or Linux Mint) $sudo systemctl restart ssh.service (Debian 7, CentOS/RHEL 7, Fedora) $sudo service sshd restart (CentOS/RHEL 6)

Option 2

If IPv6 is disabled by the SSH service of the remote host, the error of X11 forwarding failure may also occur. To solve the mistake in this situation. Open the / etc/ssh/sshd configuration file and uncomment "AddressFamily all" (if there is one). Then join the following line. This forces the SSH service to use only IPv4 instead of IPv6. (LCTT translation note: there may be an error here. AddressFamily does not have the parameter all, while any representatives support both IPv6 and IPv4. In this scenario, IPv6 support should be turned off and only IPv4 should be supported, so it should be "comment out AddressFamily any" here. )

Sudo vi / etc/ssh/sshd_configAddressFamily inet so far, I believe you have a deeper understanding of the "X11 forwarding request failed on channel 0 repair tutorial in Linux". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
