I don't think that would be too effective -- not with stubborn
people, as his sysadmin seems to be :-(

And yes, as he also pointed out, he could get fired for doing
so!!

Maybe a less aggressive move could be just to determine the root
password, then go and show it to him, reminding him that "if I
was a bad guy, I could use this to sabotage the network, or to
steal information (such as sniffing e-mail of the managers and
VPs and etc.) and use it for my benefit without telling anyone.

Then again, you probably are part of the trusted personnel, so
you may already have the root password so there's no point in
the above exercise... Still, you could try to come up with a
setup that uses none of the privileges you may have and still
get the root password.

When is this sysadmin birthday? Any time soon?

A gift such as "Hacking Linux Exposed" would be in order ;-)

Maybe another effective strategy would be to tell him to try
to convince you why he would want to *avoid* SSH... I mean,
if from a Unix/Linux console you can barely tell the difference
between a telnet login and an SSH login, then why would he be
worried?? All else being equal, why opposing to the use of
SSH? And it incurs zero extra effort or cost, as it comes
with the default distributions (I think -- at least with RH
it does ship with the default distro). Oh, that you have to
constantly keep updating to avoid security vulnerabilities??
Yeah... *that* is going to be a problem for a sysadmin that
insists that telnet is secure and unhackable enough :-)

HTH,

Carlos
