Locked outside

[Jonathan Métillon]

Hi

I'm new at Linux Forums, hello people

Here's the plot : I have a remote Devian server. I can't access it physically. After a serie of stupid manipulations I came with an infinite loop in my .bashrc file. It loads itself because of a source .bashrc line.

When I try to connect to the server using SSH, I'm kicked out after ~15 seconds, with this message:

$ ssh jessy
-bash: xmalloc: ../../bash/builtins/evalfile.c:128: cannot allocate 2343 bytes (0 bytes allocated)
Connection to jessy closed.

So the infinite loop makes bash run out of memory and I can't log in. This user account is the only one in the sudoers. And the same error happen when I try to log as root: its .bashrc file is a symlink to the broken one.

I can log in using another user, but it is not in the sudoers so I can't access the broken .bashrc file with this user. I also tried su with this user, and it fails with Segmentation fault.

Is there a way to fix this issue without accessing physically the server? Maybe there's an option or a tool that allow to log in without calling .bash_profile?

Thank you for your time.

That's ok, I've been able to use su -c using a basic user account to move the broken file:

$ su -c 'mv /home/john/.bashrc /home/john/.bashrc.bak'

And now I can log in. Thank you for your help!
