Is SSH working on gitlab.haskell.org? I'm getting this simonpj@CDW-8FABODHF0V5:~$ ssh -v git@gitlab.haskell.org OpenSSH_8.2p1 Ubuntu-4, OpenSSL 1.1.1f 31 Mar 2020 debug1: Reading configuration data /home/simonpj/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: include /etc/ssh/ssh_config.d/*.conf matched no files debug1: /etc/ssh/ssh_config line 21: Applying options for * debug1: Connecting to gitlab.haskell.org [145.40.64.137] port 22. debug1: Connection established. debug1: identity file /home/simonpj/.ssh/id_rsa type 0 debug1: identity file /home/simonpj/.ssh/id_rsa-cert type -1 debug1: identity file /home/simonpj/.ssh/id_dsa type 1 debug1: identity file /home/simonpj/.ssh/id_dsa-cert type -1 debug1: identity file /home/simonpj/.ssh/id_ecdsa type -1 debug1: identity file /home/simonpj/.ssh/id_ecdsa-cert type -1 debug1: identity file /home/simonpj/.ssh/id_ecdsa_sk type -1 debug1: identity file /home/simonpj/.ssh/id_ecdsa_sk-cert type -1 debug1: identity file /home/simonpj/.ssh/id_ed25519 type 3 debug1: identity file /home/simonpj/.ssh/id_ed25519-cert type -1 debug1: identity file /home/simonpj/.ssh/id_ed25519_sk type -1 debug1: identity file /home/simonpj/.ssh/id_ed25519_sk-cert type -1 debug1: identity file /home/simonpj/.ssh/id_xmss type -1 debug1: identity file /home/simonpj/.ssh/id_xmss-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_8.2p1 Ubuntu-4 At this point it hangs. Stackoverflow suggests https://superuser.com/questions/1374076/what-does-it-mean-if-ssh-hangs-after...a server fault. But I'm on a new WLAN so I suppose there could be some bizarre filtering? Thanks Simon
