That would be me. I gave up on 7.0 and reverted to 6.1 (with all the
security patches, of course...). I tried adding compatibility
libraries, but I'm not sure if I did it correctly. I am wondering now
if my problem may have actually been some SCSI flakiness that I
discovered shortly thereafter, but I don't have enough motivation to
check.
I really hope Mac OS X gives us Mac ease-of-use combined with unix
stability....

fyi, my 6.1 firewall underwent numerous port-scans earlier this year by one or
more people trying to get a way in. they didn't. the simple rules are,
1. don't use nfs/nis and sendmail unless you know what you're doing. it takes
approximately 3 clicks to turn these services off.
2. be aware of security updates on redhat or other distro sites. hell - at
least redhat (and other distros) get them out within a day or two of a known
flaw. i think we all know what the proprietory security model of the
alternative is like.

this is highly misleading - the reason for your colleague's comment is that
telnet, ftp, pop3, etc. all transfer passwords as plain text which may be very
easilly sniffed by someone on the same subnet. ssh doesn't because of its
public key encryption. telnet isn't some flakey door that lets people in more
easilly.

On the topic of Linux and RedHat, just got this alert from two colleagues:
just got the following messages from colleagues at other institutions
using RedHat Linux 6:
I've just learned that my Linux box (Dell Optiplex running RedHat 6)
has been hacked into twice in the last week. No damage seems to have
been done, but they used my computer as a platform to hack into others
which were damaged. A chemistry prof with the same system has also
been hacked. Apparently it's a weakness in version 6, which is absent
in 7 (not sure about 6.2). So this is just a warning to any of you
with similar setups to be careful. One time might have been from
on-campus here, but the second seems to have come from New Mexico
State in Las Cruces. My hacking was done once through ftp, which we
then disabled; the second was through telnet, which we have now also
disabled. The cure is to offload everything onto another machine,
install RH7, and then move it all back.
A word to the wise!
And a reply from another colleague
Telnet is a notorious weak point. Better to always use the more secure SSH.
I had a similar problem last summer.
Our computer center hardened up my RedHat unix system with a piece of
software called Bastille.

And I did a clean install of redhat 7 *and* idl 5.4 and have had no
problems!
It would be nice if RSI put together an RPM (assuming that they
haven't). That would solve the problem of the missing dependencies.

libXpm wasn't it?
I don't trust their use of a development snapshot of gcc rather
than a stable release. I'm waiting until 7.1 comes out before upgrading.
Which also follows the usual rule of skipping .0 releases.

Linux is gradually becoming more like Windows in every way ;-)

This isn't just an issue for linux. Just recently a Sun system I work on had been cracked (via the
ftp server). It's happened to big SGI boxes too. I would be amazed if *any* system *hasn't* been
cracked into. I can't comment on whether linux is more susceptible but I doubt it (on a per capita
basis).

Good lord. Doesn't *everyone* use SSH nowadays??? :o) If you are at some sort of institution that
has any sort of number crunching capability (that can be used for breaking into even more secure
machines) I hope that there are people employed just to watch out for this sort of thing.

not sure what this email means for me, because i did a clean rh7 install,
and idl worked fine. That is IDL 5.3, not 5.4.
