Re: [Solved] Cannot ssh aur, what happened?

Did you add your ssh-key?

first, create your ssh-key

 ssh-keygen -f ~/.ssh/aur

then edit config file( ~/.ssh/config ):

Host aur.archlinux.org
  IdentityFile ~/.ssh/aur
  User aur

of course, you need to add, your ssh public key to your aur profile.(https://aur.archlinux.org)

based on: https://wiki.archlinux.org/title/AUR_su … entication

Re: [Solved] Cannot ssh aur, what happened?

It seems to be related to proxy, because I found I also cannot `ssh git@github.com`, together with `ssh aur@aur.archlinux.org`. I test in my another device:

❯ ssh git@github.com
PTY allocation request failed on channel 0
Hi XXX! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.
# enable proxy
❯ ssh git@github.com
kex_exchange_identification: Connection closed by remote host
Connection closed by 20.205.243.166 port 22

However, in this machine, I have stopped proxy by `sudo systemctl stop v2raya`, but it still cannot work.

I change network, copy id_rsa from the device which can `ssh aur.archlinux.org` to this machine, `sudo pacman -Syu`, but all of them cannot work.

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

ssh over https can work, ssh cannot work.

❯ ssh -T ssh.github.com

Re: [Solved] Cannot ssh aur, what happened?

Sometimes, firewalls refuse to allow SSH connections entirely.

How to enable ssh for firewall in archlinux?

Re: [Solved] Cannot ssh aur, what happened?

Because it is not aur's bug. I'll open a new post to ask what happened in my ssh.
