On a daily basis, I interact with 10s of productions servers which do not, and should not have a home directory for my personal user.
Every SSH session is met with the same error message:
Could not chdir to home directory /home/Me: No such file or directory
Killed by signal 1.
Is there a way to prevent SSH from trying to cd me into /home/Me, or is there any other way to surpress this message?

"which do not, and should not have a home directory for my personal user." that is a very strange setup indeed. How is thesshddaemon expected to know in which directory you should land upon connecting? Have a look atChrootDirectorybut it needs various setup. Or something like that to adapt :ForceCommand bash -c "cd /tmp; bash --login"(ugly, and not sure that works), otherwise you need to look at PAM and speciallypam_mkhomedirthat you will need to plug from sshd PAM config.

This is the purpose ofpam_mkhomedirit creates the home directory automatically upon login, if missing. And you can centralize authentication through some LDAP server so no need to have you as user in/etc/passwd. Or it can be in the VM template. Otherwise you could always recompile your own ssh that does 'chdir /' but I am not sure it is a good idea, just try ForceCommand or even better proper user management with PAM, this will be simpler...

I don't actually now what authentication mechanism is being used. Is there a simple way to check?

well if you have access you could browse through /etc/pam.d config files or perhaps ask your server env design guys

and /etc/ssh/sshd_config should give you a clue as well

"which do not, and should not have a home directory for my personal user." that is a very strange setup indeed. How is the
sshddaemon expected to know in which directory you should land upon connecting? Have a look atChrootDirectorybut it needs various setup. Or something like that to adapt :ForceCommand bash -c "cd /tmp; bash --login"(ugly, and not sure that works), otherwise you need to look at PAM and speciallypam_mkhomedirthat you will need to plug from sshd PAM config.– Patrick Mevzek

@PatrickMevzek These are production virtual machines, there are thousands of them, across tens of different fleets. Even if I automated the creation of a home directory for me on each of them, it would only be temporary, because VMs are shutdown and created as necessary to fit demand.

@PatrickMevzek Ideally, I was hoping there might be some flag to tell SSH to spit me out at

This is the purpose of
pam_mkhomedirit creates the home directory automatically upon login, if missing. And you can centralize authentication through some LDAP server so no need to have you as user in/etc/passwd. Or it can be in the VM template. Otherwise you could always recompile your own ssh that does 'chdir /' but I am not sure it is a good idea, just try ForceCommand or even better proper user management with PAM, this will be simpler...– Patrick Mevzek

@PatrickMevzek I'll talk with the devops team, see what they think. I suspect they wouldn't be too fond of the idea of every ssh'ed user opening new dirs on prod servers
