Package: ssh
Version: 1:3.6.1p2-9
Severity: normal
Tags: sid
The sshd daemon fails to start up on boot, or when issuing "/etc/init.d/ssh start",
or on a simple "sshd". There is no error message -- in fact the receipt is normal
in the case of the init.d script: "Starting OpenBSD Secure Shell server: sshd" and
no newline.
In contrast, starting the ssh service with a simple "sshd -D" works without problems.
I put /usr/sbin/sshd -D >& log & into /etc/init.d/bootmisc.sh and have normal
functionality.
The problem may well be due to another package; I'm unsure how to troubleshoot.
Same results with 1:3.6.1p2-11.

My guess was right:
[...]
> open("/dev/null", O_RDWR) = 3
> fstat64(3, {st_mode=S_IFREG|0644, st_size=7242, ...}) = 0

[...]
Your /dev/null has somehow become a regular file instead of a character
device, which means that the daemon() library call fails. Fix that. As
root:
rm /dev/null
mknod -m 666 /dev/null c 1 3
If you could track down what broke /dev/null and file a bug on it if
it's a Debian package, then that would be helpful.
Cheers,
