There's also a submit.cf for the "client" portion. What are the errors that are being seen? That wasn't specifically mentioned in the original post. There was something about the "MX loops back to me" thing, but I don't know if that's the error you're seeing or not. -- Randomly Generated Tagline: "A way out of financial mess is discovered as if by magic!" - stupid fortune cookie

It's in a select/timeout loop. I just tried Charles Anderson's suggestion (his email came shortly after yours). That cured the lock-up. Now on to see if I can get something done... Thanks, Bill

Re: [Wlug] rpm lock-up

Documented bug in rpm-4.1. To fix: kill -9 the hung rpm process rm -f /var/lib/rpm/__db* If it still hangs, repeat that process and add this step: rpm --rebuilddb On Thu, Oct 31, 2002 at 09:52:31AM -0500, Bill Mills-Curran wrote: subssn594> 2.

I don't use rpm, but I'd suggest running strace on the rpm command to see what the problem might be. strace rpm <args> -- Josh Huber

jsut a thought

by doug waud

Hi all After the neglegible turnout of "customers" for our most recent installfest there was some discussion aa to whether the day of the installfest is past and we should look for other ways to serve the community. In this context I found this morning's (Oct 31) T&G had an interesting article which may provice a template for what we might now do. In a nutshell they described (pages A1 and A11) the Atlantic Paranormsl Society who for the past 12 years send out teams to help people who are having trouble with "domestic disturbances like eerie noises and signs of spirit possession". Their website, http://the-atlantic-paranormal-society.com/ gets 6000 hits a day from around the world" (they do not say whether setag lib is among them). They do not charge for their "work" and say "the rich and poor both need help" and say "Also how can you charge for something that cannot be proved to exist" (which does not seem to stop Micro$oft!). They have about 25 regular members, consult with a network of similar groups and gather at an eatery (Starbucks, not the Boynton). I suggest that, if you can find today's T&G you read the article since I cannot do justice to it here. For example, I learned about the taxonomy: Hauntings Human Intelligent spirits (they talk) Residuals (leftover energies condemned to repeat one small action from their lives) Poltergeists ("usually the spirits of young girls which make a racket and and can wreak havoc on property values") Inhuman Demons Incubuses Succubi Nature spirits Angles Apparently the human variety are the more "benign" while the others "can be viscious and deceitful", says "Never believe anything you hear from an inhuman haunting". Apparently other groups often get in over their heads and haveto call in his crew to "clean things up". (This is getting long; check out the T&G if you do not wish to miss the full picture.) Now I realixe some of this may sound scary but we would have the advantage that we could send Keith in first to scare the spirits! :-) So, instead of instalfests we could adapt to the times and move into deinstallfests! doug

rpm lock-up

by Bill Mills-Curran

HELP! I seem to have done something very bad (SVB) to rpm. And, it seems to be painfully reproducible (I did it to two machines). Short explanation: 1. Do some rpm command (I was using "rpm -e", I think). 2. Ctrl-C out. You won't get the shell prompt back. Now, that user account can no longer do any rpm commands from any session -- it always hangs. You can kill -9 the existing rpm processes, but nothing I've tried helps until reboot. Longer explanation: 1. I wanted to upgrade a couple of packages: perl-GD and perl-Chart. I don't know where I got the old packages :-( , but I made some new ones of my own. 2. Instead of doing "rpm -F", I forgot that the perl modules were installed from an rpm in an older perl library area, and I deleted the module files (rm). (oops) (Is this clear?) 3. When attempting to install the new rpm's, I got error messages, so I tried "rpm -e" on the old package. That failed due to dependencies, so I added "--nodep" to the command. This was taking a long time (hung?), so I ctrl-c'ed out. Now all rpm commands (from the root account) hung. 4. I rebooted this morning. The rpm commands were working ok (at least "rpm -qa" worked), so I tried "rpm -F <packageFileName>" (as root), and it's hung. 5. From another window (also as root), "rpm -qa" hangs again. 6. From a different account, "rpm -qa" works fine. HELP! 1. How do I fix things and get my new packages in? 2. Is the database corrupted? 3. If the database is corrupted, how do I fix it? Thanks, Bill

Sendmail 8.11.6 (was building RH7.3 after hack)

by Richard Goodman

I spent four hours on Google last night about this problem. Saw reports of the same messages, but not the same situation. SUMMARY: 3 separate servers upgraded from RH7.0 to RH7.3 - all can send/receive mail locally and to/from the outside world EXCEPT for/from each other - which was not a problem under RH7.0. Do not believe there are errors in config files, particularly /etc/mail/local-host-names, and I have read the part of the sendmail FAQ about "mail loops back to me" and it DOES NOT APPLY in this case. I've been through what sendmail documentation I can understand - can someone tell me what has changed somewhere prior to or at 8.11.6 which shipped with RH7.3 that might cause this? I have another identically hacked RH7.0 server which I hope to rebuild/upgrade tonight - it will be interesting to see if all FOUR servers have the same problem. I'm losing mail which is supposed to be forwarded between these servers. Dick

I believe (not sure!) that the change occurred in RedHat 7.3. 1. sendmail is broken up into 2 separate processes for security reasons. One is outgoing, the other is incoming. 2. /etc/sendmail.cf is no longer used. There are several files in /etc/mail to replace /etc/sendmail.cf. 3. The new *.cf files are generated from several macro-preprocessed files. You get to edit sendmail.mc and submit.mc. The documentation in /usr/share/doc/sendmail/README.cf is good, but long. 4. The *.cf files are generated by the macro files when you start the service. (See /etc/mail/Makefile.) 5. The file /etc/mail/access can define where your server will accept relay mail from. I used the access file to allow all my domain machines to be able to use my alias list. However, I suspect that I should be handling my aliases differently -- I haven't gotten around to figuring it out yet, but this now works. I wish I could help more, but I'm pretty green with sendmail. Bill

RE: [Wlug] RH 7.2 - Installing and configureing openssl, modssl, apache, and php

by Setag Lib

Redhat has RPMS for apache, php, and ssl that all play nice together. Use those unless you have some weird requirement where you absolutly need to build your own. BUT, make sure to download the updated SSL libraries from RedHat! The ones on the CD have a remote exploit in them that you will want to close. If you do NEED to compile your own apache, ssl, etc ... then there is this nifty project called "The apache toolbox" http://www.apachetoolbox.com/ which makes the process much much easier. Since it can be difficult getting all those to work right, I'd suggest trying that. I'd un-install all of the current apache stuff you have before doing that.
