Summary: check_ssh does not properly close connection

Initial Comment:
with 1.4 and later, it looks like check_ssh doesn't
properly close connections.  for example, this is the
previous behaviour of check_ssh in the 1.3 series:

Apr 11 10:24:03 appsrv1 sshd[9822]: Connection closed
by xxx.xxx.64.52

but in 1.4:

appsrv1 sshd[10154]: fatal: Read from socket failed:
Connection reset by peer

i think this is just because close() isn't being
called.  i will verify this shortly...

It's check_ssh, not check_by_ssh.

There's no close in there, and no signs of seanius's commit. He either
forgot to commit or commited it to the wrong branch...

I'll take a look shortly. Since I never used check_by_ssh it'll help if
you can give me a sample command-ling and what to look for (In logs I
guess), so I won't have to reinvent the wheel :)

Thanks

This is still a problem in 1.4.3 -- evidently, close() is not enough.

yup, calling close() before exiting resolves this problem,
i've committed a change to cvs
