$ sudo vi /etc/ssh/sshd_configĪgain, restart SSH server to finalize the change. This will force SSH server to use IPv4 only, but not IPv6, so that SSH server complies with the IPv4-only server settings. To fix the error in this case, open /etc/ssh/sshd_config file, and uncomment AddressFamily all (if any). The broken X11 forwarding error may also happen if the remote host where SSH server is running has IPv6 disabled. This protocol allows the users, especially system administrators to access a computer over an unsecured network. ssh remotely connects to the target host and reports an error: shell request failed on channel 0 Reason: The number of system processes on the target host. Restart SSH server to activate the change: $ sudo /etc/init.d/ssh restart Secure Shell or better known SSH is a network protocol that enables two computers to communicate. To fix this problem, add the following line in /etc/ssh/sshd_config file, which will let X11 forwarding server bind on the wild card address. Under this setup, some X11 clients cannot handle X11 forwarding properly, which causes the reported error. Solution Oneįor security reason, OpenSSH server, by default, binds X11 forwarding server to the local loopback address, and sets the hostname in DISPLAY environment variable to localhost. Solutions vary as well, as desribed below.

If you are getting "X11 forwarding request failed on channel 0" message upon SSH login, there could be several reasons. It hangs at the end, after authenticating and sending the command, with. Why am I getting this error, and how can I fix this problem?įirst of all, we assume that you already enabled X11 forwarding over SSH properly. I'm pretty lost here.Question: When I tried to SSH to a remote host with X11 forwarding option, I got "X11 forwarding request failed on channel 0" error after logging in. Many people have had this issue on StackOverflow as well, but I see them marking an answer as the correct, but those did not work for me. I did try to use my initials instead, but that yields the exact same response. The other guy's SSH URL is wheras Bitbucket automatically shows for me.
The other guy's private key is not password protected. Once youre in debug more, you will see lots of messages elaborating the. Something I know for a fact that nobody else has. Now, to trouble shoot this issue, I must run the ssh in debug more using -vv option. I have verified with ssh-keygen that the private key /home/user/.ssh/id_rsa does have the public key I attached in Bitbucket. I have entered my SSH public key into (which starts with ssh-rsa XXXXXXXXX) When I try to SSH into the server with -Tv flags, I get this output: debug1: Found key in /home/user/.ssh/known_hosts:6ĭebug1: Authentications that can continue: publickeyĭebug1: Next authentication method: publickeyĭebug1: Offering RSA public key: /home/user/.ssh/id_rsaĭebug1: Server accepts key: pkalg ssh-rsa blen 277ĭebug1: Authentication succeeded (publickey).Īuthenticated to (:7999).Īs you can see, it authenticates me properly but for some reason replies with shell request failed on channel 0 git clone denied (publickey)įatal: Could not read from remote repository One member of my organization at work has successfully authenticated and cloned the repository (same I am trying to clone), but mine keeps failing. I tried to get file path to the repository.
However, the shell clearly doesn’t work as I can list files in Gitlab home directory and use other bash commands.
As far as I know, I am supposed to be greeted by Gitlab shell. I am trying to use SSH to clone a repository, instead of HTTPS, to see if the speed is faster (it's a large repository). When I try to ssh to the same hostname using the git user I get: PTY allocation request failed on channel 0.
