Won't people simply wait 48 hours before spamming then?

Sdf has a 1-month free trial period with greatly reduced privileges then you
can send in $1 to join, which spammers are not likely to do. Would it be
worth the nuisance of making people send in $1 to use outgoing email?

Sending a dollar by US mail is not difficult.

Unless you are not living in the US.

You could ask people living outside the US to send a postcard instead.
That should be enough to stop spammers. I was thinking it might be a nuisance
to the treasurer having to collect this extra mail. I have alternative mail
and I still prefer grex mail (or sdf) to webmail or pop mail.
sdf takes 2-3 weeks to receive the dollar and activate the account.

I don't think collecting the mail is a problem, but there is added work in
doing something about it for every new user. Newuser is automatic for a
reason. Instead, create some kind of online hoop the new user must jump
through that delays activation of e-mail for a week or so. Like, writing a
100 word essay.... 8^}

A computer could write essays, plagiarized from any place.

When I tried to log in at 15:56:18 system time, I got the following
error, followed immediately by a disconnect.
-bash in malloc(): error: recursive call
I've gotten this once or twice before, always using SSH (and always
from the "SSH Secure Shell" client for Windows (running XP), which
doesn't give any more information about itself than that in the
Help About box).
I connect again fine immediately (well, as soon as I can tell it
to connect and give my password, anyway).

Ok: rn
News on Grex is down, and has been for a couple of years now.
At this point it is unknown if news will ever be back. Sorry.
In the meantime, please load Lynx and go to http://groups.google.com/
:(

I just fingered a user on Grex and got a couple of lines like this:
Last login Wed Dec 21 09:05 (EST) on ttyp9
from ...
Mail last read Sat Jan 7 22:22 2006 (EST)
Since there's no way I know of to read Grex mail without logging in
(except ftping the mail file), I'm wondering how the "mail last read" date
can be later than the "last login date". Is one of them bogus?

Surely he was on for enough time for that? Try the "last [user]" command to see
how long he was on.

Er, "perhaps" rather than "surely."

Well, in this case, he would have had to be on for 17 days straight, which
seems unlikely. So I hecked last as you suggest, and in fact the user in
question was logged on for only 23 minutes on Dec 21, and hasn't been on
since.

I just checked, and "last" can be fooled -- I su'ed into my own account, and it
only caught the outer process, not the inner one. There's probably other ways,
too.

Did you "su -"? Last checks logins, not processes. "Su -" logs you in (again),
whereas "su" only starts another process with superuser processes.

"Su" logs you in (so to speak; you're right that it akes "su -" to create a
login process) as whoever you specify, provided you know the password. (If you
don't specify, it assumes the superuser.)

Last does not register your login when you login via backtalk.

Yes, but it's hard to read your mail via Backtalk.

It appears if you log in with a non-interactive shell, for example:
"ssh grex.org bash -i"
no login record is made.

Can anyone figure out why sdf just stopped working a few minutes ago?
I can't even access the website. I sent a mail, then could not send the next
one, then could not read mails, then could not ssh back in. Is this a crash?

Could be a network outage but I suspect a machine crash or a network
break somewhere relatively close to them. The traceroute from where
I am in Tokyo is fairly long but dies a few hops into att.net's
network.
