[Solved] Cannot ssh github and aur

Freed · 2022-11-18 10:56:58

In my desktop, I can ssh localhost and my mobile, and can ssh github over https, but I cannot ssh github and aur.

And I can ssh github and aur from my mobile.

❯ ssh github.com

Hello, world!

This is

~/.ssh/config

StrictHostKeyChecking no

Host github.com
  User git

# https://docs.github.com/cn/authentication/troubleshooting-ssh/using-ssh-over-the-https-port
Host ssh.github.com

  Port 443

Host aur.archlinux.org
  User aur

Host localhost
  UserKnownHostsFile /dev/null

Host mobile 192.168.43.1
  HostName 192.168.43.1
  User wzy
  UserKnownHostsFile /dev/null
  Port 8022

According to https://docs.github.com/cn/authenticati … https-port

firewalls refuse to allow SSH connections entirely.

How to allow ssh connections in firewalls? TIA!

Why are you trying to ssh into github? You don't remote accsess into github's servers, you use git clone.

You don't have shell access to GitHub and AUR. What's your intent?

I

ssh github

just for test my ssh is normal. In fact, I can

git clone https://github.com/XXX/YYY

not

git clone ssh://git@github.com:XXX/YYY

. However aur allow git clone by http but not git push for http. The only one method to git push to aur is by ssh. According to I doubt any program control my proxy such as VPN program but I don't know how to find them.

However aur allow git clone by http but not git push for http.

The git clone done over htpps from aur is readonly , pushing from a readonly clone is impossible regardless of the protocol used.

For (co-)maintainer a readonly clone is uselesss, you need to start by getting a r/w git clone over ssh .

ssh'ing to aur

$ ssh aur.archlinux.org
PTY allocation request failed on channel 0
Interactive shell is disabled.
Try `ssh aur@aur.archlinux.org help` for a list of commands.
Connection to aur.archlinux.org closed.
$

So technically I can ssh to aur from my desktop.

What does that command output on your desktop ?

Thanks for your help. It seems that a proxy software v2raya (I just use it to avoid GFW) force all terminal program to use its proxy.

❯ ssh aur.archlinux.org

Try `ssh aur@aur.archlinux.org help` for a list of commands.

  vote <name>                       Vote for a package base.

I try to find how to let this proxy software don't force my terminal program but
I cannot find any variables like $socks_proxy. Now I have to stop it when I use
terminal and start it when I browse Internet. Does anyone know any convenient method?

I have found the reason. v2raya start a system-level systemd service which results it. Now they have changed it to user-level systemd service. Hope my experience can help other one meeting this bug: please update your system by

yay -Syu

. Thanks!
