is /var/adm/messages supposed to be empty?
maybe it's been moved to the unreadable /var/log

What is the language of Shell scripts? And how is the sintax of the shell
scripts? I have used some UNIX commands, but they are not run. what is it
wrong?

Hi, Gestway !. There is a separate item for asking questions about how to
use grex (15 or 16?). Welcome to the grex conferences. (I have been
chatting with gestway for a while and exchanging emails. He is a student at
a university in Indonesia, good at both computers and English.)

Grex's telnetd is launched by inetd, which periodically croaks for unknown
reasons. There is a system daemon that automatically restarts inetd within
8 minutes after it dies. The restart is done by "robocop" a daemon who's
primary purpose is to kill users who use excessive memory or processes (mostly
various types of fork bombs) and to kill any processes that users leave
running in background after logging off. It does a number of other
housekeeping chores too. So generally if ssh works and telnet doesn't, then
waiting a bit should fix things.

"8 minutes". Thanks, I'll try to remember that. :)

Does ssh tie in to the waiting list mechanism? Is there anyone putting any
thought into developing that if not? What about upgrading to ssh v2?

If there is a queue, ssh fails to assign a pseudo-tty. (or is that just if
the queue is full?)

Marcus is working on sshd upgrades. It turns out to be hard to make it queue.
It was possible to make it mostly-fail if there is a queue, so it can't
readily be used to bypass the queue. I believe he is working on improving
this situation, and on upgrading to a more recent release. So currently ssh
is only semi-supported on Grex. Actually, staff members pretty much always
connect with ssh, but if the queue is full we can ssh to one of Grex's other
servers, which don't have queues, and from there to Grex (the queue only
applies to users connecting from outside the cyberspace.org domain).

I wonder what the issues are? Seems like if you just insert a queue check
after the authentication but before forking the shell, and only fork the shell
after the queue countdown program exits, it would do the trick.

Hmm...would the UseLogin option to sshd help with implementing that? I
only have a vague idea how this works, though.

I don't see that UseLogin is supported in the ssh v2 config file. Probably
a ripe target for security holes. However, it would appear that the
"Subsystem" mechanism (used to implement sftp) might be usable in this
respect.

The network time protocol service is not working on Grex at the moment, and
the time is off by some 30 seconds into the future.

Re #25: It doesn't use reverse lookup. It knows what IP numbers Grex owns.

A friend of mine is having loads of trouble emailing me because his email
path goes through "pacbell-dot-something." He said grex has a policy of
not receiving email from this server. What's up with that???

You probably should email Marcus about it, Katie. At a guess it's a friendly
home for spam or something of that sort.

re #14: only if you've been cracked or it's just been rotated. however
for all i know grex logs elsewhere and that file is never larger.

That seems likely, since that file was last updated in 1997.

You already know that Comcast changed all their customer's email addresses,
discontinued usenet news service, discontinued allowing multiple email
addresses, increased prices, and mailed out a CD to all their customers that
"eases the transition" by installing lots of irrelevant software, sticks
Comcast's name all over your desktop, and hoses your system configuration.
For additional fun, they've installed a proxy web server that filters out
Grex. So Comcast customers can not access Grex's web pages now.
Valerie has spent about an hour and half on the phone with them trying to
convince them that there was a problem. She ran out of time and hand to hang
up on the them without success. If anyone more annoying and persistant wants
to call Comcast, that would be OK with us.

Oops, I missed few: Comcast also supplied instruction to their customers
who were paying for static IP addresses for how to "maintain their
connectivity". The instructions reconfigure your computer to use a
dynamic IP. They have a typo in the IP address of one of their two DNS
servers. The correct addresses turn out to both be on the same subnet,
largely nullifying the utility of having two.
In otherwords, the entire new Comcast network was thrown together overnight
by a bunch of people who had barely any idea what they were doing.
