Re: e2fs unstable on powerdown
Steven Jones napsal(a): convert ext2 to ext3 it is quite simple. I have had RS file systems loose iteasier then ext2...from power failures, I would advise ext3 it is very robust. OK, gonna getta tune2fs -j /dev/hda1 /etc/fstab : ext2 - ext3 /etc/default/rcS : FSCKFIX=no - FSCKFIX=yes I had a bit irrational fear about performance consequences of journaling - the machine is a bit outdated - P75 64RAM and goes 50% CPU now, but I have not the heart to give it the air :-) Your blaming a file system issue with a power failure, sorry its your power that is an issue, I have Solaris boxes, tru64 boxes and NTx boxes all get upset if they have frequent power failures, so ext2 and Linux is not at fault. It was not really blaming - I only wanted your advices how to proceed.. Get a UPS with a parachute system to shutdown your server. And/or if you know 99% of your power failures are 30 mins and only happen once a week then size the UPS to cope with a 1 hour outage with a recovery of 2 or 3 hours. Online UPSs are the best but cost the most and are usually OTT, unless your line in has severe sine wave and spike issues in which case an online ups is your only viable solution. I know - UPS would be the best solution, but the budget is extremely limited and powerdowns are not more frequent than 3x a year. The other trick is to look at a UPS with a big charging circuit but small batteries, ie one designed for expandibility) you can then add car batteries to it very cheaply to give massive capacity for at most the same cost as the dry cells that the UPS normally uses...ie keep the server up all day Really interestig... UPS tuning :) regards Steven aka thing Cheers David aka David -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
sagator vs amavis-new
I'm going to enrich my postfix with opensourced anivir/antispam solution. IMHO the best solution will comprise clamav and spamassassin, but I hesitate a bit between amavis-new (well known, proved) and sagator (new, one-man-show, modular design - plugins for tens antiviral/antispam sw). What's your opinion, guys? With regards David -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
e2fs unstable on powerdown
Hi! I'm facing severe problems with e2fs on low-volume server with Postfix and NSD running. Every time the power goes off, the / is mounted ro (which is meaningful) and is a bit corrupted (10-20 files with 0 size, bad owners, completely lost etc.). I know, the best solution would be to buy the UPS, but is a such unstability common? I wouldn't be surprised in case of Raiser with cache enabled, but ext2 is known as a relative stable fs. Should I tune something or is the UPS the only way? Thanks for hints! With regards David -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Re: qmail or postfix? (was: RE: What is the best mailling list manager for qmail and Domain Tech. Control ?)
Can someone write here an easy understandable configuration for Postfix with virtual domains ? After some call for help here, none of you that know Posfix did it... there is an easy understandable VIRTUAL_README in postfix docs yet (at least in woody version), so it's not necessary to write another one; moreover on the Net, there are many howtos for specific situations if you run into trouble with the info, let send more specific questions. regards David -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: bind9 vs tinydns vs others
thanks for reply! i only guess, as well as your dns depends on some database (RDBMS or LDAP or something else), it increases the danger of attacks, especially DoS (db is down - dns respectively). flat files can't be down. wouldn't be better to generate flat files from the backend db to avoid such risks? have you ever had such problems? David David Zejda wrote: what do you prefer for authoritative dns? experiences/stability...? i have no verbose bind knowledge yet. thanks David We are running mydns on our auth name servers, feeding them data from a self made PHP-based web interface. Works like a charm. Only drawback is it's only available in testing and unstable (but most of our servers un testing and are rock stable) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: the best email solution
I'm building a new server from the scratch. There are such requirements for mail: virtualHosting no plain password sendings WebMail (OpenWebMail preffered) SMTP (? Postfix) POP (? vm-pop3d) IMAP suggests? And one question more: What's the best storage system for user accounts? RDBMS? LDAP? Is there any way, how to manage user accounts for all services (webmail, pop3, smtp, imap) from one place?

Lazy Apache with domains
I have a machine with NIC, but not connected to network yet. In etc/hosts there is a record 127.0.0.1 localhost mydomain.com lynx 127.0.0.1 performs normally but lynx localhost says something like looking up localhost for a 5s and than localhost for next 5s before finally (after 10s) showing page. It does the same mischief for lynx mydomain.com. It doesn't matter whether domain is set as a VirtualHost or not. What should I check, please?
