Subject: No longer generate RSA1 SSH hostkey [Closes: issue2158]
X-Git-Tag: v1.6.0~2
X-Git-Url: http://git.grml.org/?p=grml-etc.git;a=commitdiff_plain;h=697b566015261102d951410e21659d23901e2a1a

No longer generate RSA1 SSH hostkey [Closes: issue2158]

Otherwise executing ssh-keygen for rsa1 fails with
"failed: unknown or unsupported key type" with recent openssh
versions (like Debian unstable's 7.1p1-6 as nowadays)
and sshd doesn't start up.

Thanks: Andras Korn for the bugreport
