What group is this? Throwing the combo of Solaris and 2k together makes me
think something to do with IT. =)
Personally, techrepublic.com is pretty cool. They have some cool articles
every once-in-a-while. I did some NT stuff a few months back and did a
presentation to WNUG...backing up ACLs, ERDs, DHCP databases, etc etc. The
nixen part of it was writing to a smb share on linux box. =)
As for security at ASU, heh. They're testing the ASURITE/kerberos stuff with
W2k. The goal is to get everything to authenticate in the krb domain. I
think the problem they're running into is having w2k clients authenticate
against the current nixen krb servers, or it's the other way around. krb is
the way to go at asu though, that's for sure. On the nixen machines, don't
bother with AFS though...they're going to stop using that in a few years,
moving to DFS (not MS DFS), so I've heard.
**HANS: We need to get that tour scheduled. =) **
As for automation and s/w comparison for windows machines, you should be
able to get SMS through IT for your group. Make sure you get 1.2 and not 2.0
(unless you don't want to support Macs <g>). We used this for package distro
stuff to the windows machines (only nt4 right now), and it worked pretty
well...now we just use ghost or LabExpert (LE is *very* cool...one of the
coolest damn things i've seen). Registry hacks are still your best friend to
make sure each system does things the same (eg, coordinating a/v updates and
upgrades).
I'll be starting on a nixen s/w comparison deal here in the next few days,
hopefully. We essentially run a mirror of redhat, and have all the RPMs
local on an NFS export to, well, the world. <g> The problem is that with
god-only-knows how many linux boxes in the dept., we have a hard time making
sure things are up to date on all of the boxes we administer. The goal is to
tie it into bb (we love bb <g>) to get the list of machines to update, and
so on.
Central administration rocks.

Hmm, I start a job in the CC next monday doing sysadmin work for a small
group
of people at ASU. My job is basically to take over that part of their work
so
they can devote their time to a program they are writing. Looks like I will
be
handling Solaris, BSD, linux, NT and 2000. Security is an issue that I will
be
facing and it's not something I've spent much time worrying about. My
systems
are behind a cisco router 675 (not that it's very secure, but it does have a
changing external ip). Haven't done much even when the router was in
bridging
mode (configured ipchains to only allow forwarding from the internal network
if
destination was not on the internal network and to ignore any external
requests
that weren't initiated internally) Kinda simplistic, but the box was there
just
to do masquerading for my 9 other systems in the house (NT, Win98, Linux,
2000
server, etc...).
Without doing an 'rm -rf *' or 'format c:', what are some good sites or
utils
for aiding in tightening the hatches on a system (i.e. how-to's, or sites
similar to
http://www.securityfocus.com).
Also I will be working on Automation of the NT systems to make sure they are
all
running the same software, anyone have any experience with this or have
pointers
for how. I vaguely recall something for the win95 resource kit doing this,
damn
wish I hadn't gotten rid of it.
