Its a blip on a radar not worth mentioning unless you want to feed the troll.

On another matter, concerning what might be a problem - or a policy.
I put a small .jpg file of the MNAC logo in the mnac web page here, but
the link to it from the webpage remains broken. Does the system
automatically refuse access to jpegs in the www directory? If so, is this
still necessary, with the increased filespace now available?

Grex doesn't allow graphics, but you can get around that by making it a
SVG and embedding it into the HTML. :-)

I cannot send mail from grex to grex today - I tried answerig three different
people (from three continents).
Rane, post the jpeg at some other site and link to it from the grex page.

Use arbornet.org for your webpage.

Does Arbornet allow you to use graphics? I use sdf because they give me
a neato multics.org domain. 8-)

Re #229: already did that.
How about HVCN for hosting websites? Their conferences seem to have died in
1999, but apparently they still host nonprofit websites. I considered going
there for MNAC, but wasn't anxious to change the URL.

A friend is reporting that my mail is bouncing because the ?SMPT server is
refusing connections? Anyone know about that?

In the strictest sense it's not *refusing* connections but it doesn't
seem to be working properly, either.. I've telnetted to the smtp port
and can't get as far as HELO, so I'm going to try resetting the exim
process..
mcnally@skookum:~$ telnet grex.org smtp
Trying 216.86.77.194...
Connected to grex.org.
Escape character is '^]'.
HELO
554 SMTP synchronization error
Connection closed by foreign host.

I try to telnet www.grex.org: Unknown host. I can use web interface
and I can telnet to sdf.lonestar.org (Can't try ssh at the moment
because it won't work on this computer with this linux, anywhere).

I could dial in directly to grex just now. Can other people telnet/ssh?
I was testing a lucent modem and maybe it does not like grex.

For AAAGES I hadn't been able to ssh in direct. I had this problem I while
ago and got it fixed, but screwed up my ssh config after an upgrade so that
it wouldn't work again. For the past few weeks I have been either ssh in
direct from a laptop running SuSE, or ssh'ing in to dahmer.vistech.net and
then to grex.
Today, without thinking, I ssh'ed direct into Grex from my Gentoo box.
And it worked.

Re that problem of SFTP-ing to mnac: Changing /lib to /etc for .login and
.cshrc source directories fixed it. So it had nothing to do with the pw
files per-se.
I also solved the jpeg problem for a homepage by putting the jpeg
elsewhere and linking to it. But the question remains - does Grex still
really need a no jpeg rule for web pages?

Where is the ssh config file? I have somehow copied a newer version of linux
on top of my old one without /etc. Got to copy that some time, maybe it will
fix the ssh problem. PRNG not seeded.

I don't see anything related to ssh in /etc. I should read the man page and
see what else I may have omitted. Maybe in /root?

Actually, what Rane is reporting is that his csh startup scripts
sourced files (global.cshrc, global.login) that used to live in
/usr/local/lib, apparently.
So there was a line in his (or rather MNAC's) startup files that
read:
source /usr/local/lib/global.cshrc
Since those files now, for some reason, live in /usr/local/etc
the startup script would cause an error when he logged in and
it was this that was apparently affecting his ability to sftp.
Changing the line to:
source /usr/local/etc/global.cshrc
fixed the problem (as would simply commenting out that line..)

Re resp:194: In the past, vandals like this have eventually gotten
bored and left, or sometimes even started to participate intelligently
in discussions. I don't think extreme measures like disabling newuser
are called for, yet. Furthermore, the more attention you lavish on
these jerks the longer it will take for them to get bored with their
stunt.
Re resp:238: Re the mail problem...It's complaining because you're
saying HELO before you get the connection banner. That's not
RFC-compliant behavior, so Exim hangs up on the connection. (Hosts are
explicitly allowed to delay the banner as a slowdown technique, for
example if they're under high CPU load.) I suspect the connect ACL is
delaying sending the banner for sites that match spam blacklists,
because this is a pretty useful technique against spambots, and I think
I suggested it once. Every once in a while you may find a broken host
you have to whitelist, though. I have no idea if this is still
effective against spam, or if the people who write spambot software
have caught on; it's been a few months since I was administering a
serious mail server of my own.
