Password is asked for multiple times

Open sumanthratna opened this issue 5 years ago • 3 comments

From #115:

I ran sshcode <ssh alias> and I was asked for my password 4 times. I can't set up passwordless ssh because of the way Kerberos and AFS are set up on the remote server.

It would be great if there was somehow a way to only ask for the password once. However, this would probably sacrifice some security.

This issue came back. Yesterday, December 29, 2019, I re-ran go get -u go.coder.com/sshcode to update the package.

Output of sshcode tj:

I'm on macOS 10.15.3 Beta. sshcode --version prints a newline (#154), but I installed sshcode via go get.

sshcode --ssh-flags '-o "ControlPath=/tmp/test" -o "ControlMaster=auto" -o "ControlPersist=5m"' tj works fine, but I still think #116 should be fixed because the SSH connection will be kept after sshcode is quit.

For some reason the master doesn't connect in time. Are you typing in the password and hitting enter quick enough?

Sorry for the late reply! I just tried again and I entered the password immediately after it was asked for. sshcode works fine, but the original problem still stands—I was asked for my password 5 times.

I face the same issue with public key auth:

2020-05-20 09:04:21 INFO	starting SSH master connection...
2020-05-20 09:04:51 ERROR	failed to start SSH master connection: SSH master wasn't ready on time: max number of tries exceeded: 30
2020-05-20 09:04:51 INFO	ensuring code-server is updated...
...

The following sync and startup succeeds, but the first connection always times out.
