Package: bash-completion
Version: 1:1.0-2
Severity: normal
Tags: patch
I have a few IPs that has their OS replaced on a regular basis, for
these I have /dev/null set as their UserKnownHostsFile.
The eval line used to expand $HOME etc, is dangerous (probably only for
the users of a system if you have a BOFH). With multiple entries the
next entry will be tried to be executed;
kni...@traktor:~$ grep UserKnownHostsFile .ssh/config
UserKnownHostsFile /tmp/lo l
#UserKnownHostsFile /dev/null
UserKnownHostsFile /dev/null
kni...@traktor:~$ ssh [TAB]bash: /dev/null: Permission denied
