[Correction] [ILUG-BOM] [security]tcpd
by Fart Crimson 18 Aug '01

18 Aug '01

I don't mean to be a swaggerer, but, i just need to correct a small part of the *excellent* piece by Kishor :-) > There is one important file..called /etc/services, that lists all the > services your box is offering to the outside world. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Actually, the "/etc/services" file simply lists the ports and protocol names. Its purpose is to provide mappings between the protocol names like telnet, ftp etc., to their respective port numbers. It *does not* mean that the services are actually running. Pleeease, please, please *do not feel hurt*, Kishor, since that is not my aim. I am sorry if you feel otherwise. In any case, thank you for taking the initiative to start the discussion :-)) Fart

Regd. GNU/Linux No. (was external modem)

Is this number something similar to > usernames given to members of a website? I think similar number > was displayed at Philip's homepage also. Please explain. The No. is alloted to you if you register yourself as a GNU/Linux user at http://counter.li.org/ You will find what the whole thing is all about at the site. Once you register, you will also get a small logo made of Tux and your Regd. No. on it! :-). Though - the last time I checked - they provided GIF logos (Don't tell ESR 'bout this) probably because they are using GD (nevermind). Although, you can simply convert it to PNG so that Unisys doesn't come knocking your door askinng for royalties! I will end now, too much pointless blabbering, I have a hangover Fart

Fwd: qmail starttls patch does not seed the random number generator

For anyone using ssmtp with qmail ---------- Forwarded Message from Felix von Leitner ---------- Subject: qmail starttls patch does not seed the random number generator Date: Wed, 15 Aug 2001 02:57:36 +0200 From: Felix von Leitner <felix-qmail(a)fefe.de> openssl-0.9.6b does not allow ssl/tls connections when the random number has not been seeded. This is a good idea, and it exposes that the starttls patch for qmail does not seed the random number generator. Here is a small patch that fixes the problem in qmail-remote for systems that support /dev/urandom (the same can be done for qmail-smtpd but I can't test it right now). Not seeding the random number generator is a serious bug and it completely compromises the cryptographic privacy of TLS encrypted emails.

printing
by noel seq 18 Aug '01

18 Aug '01

Hi guys, I installed a local printer and a remote printer. But after giving the print command lpr -Plp file lpr -Plp0 file i get the error lpr: connect: connection refused jobs queued, but cannot start daemon it just does not print, but goes on queueing in the /var/spool/lpd directory. Only when i stop the daemon, it prints all that is in the queue. How do i set it to start printing directly or after the job is spooled.

Its not a problem either on your side or Dishnet ("we don't support Linux" :P) - its MTNL (?@$#!) It happens when the modems cannot sustain a connection due to (mostly) excessive line noise. The /etc/wvdial.conf file is used by `wvdial' and *not* by kppp. PS: Try to find some point in the Terms an Conditions of Usage given to you by DishNet so that you can maybe screw them a lil' bit ;-) Fart
