RE: Hard disk lock down.
Thanks for your advice. I checked 'D' stats process numbers and compare with uptime's value.. yes, your opnion was right. :-) but I couldn't prove what occurs problem. There are'nt special messages in kern.log and dmesg. I'm using 2.4.5 kernel. What can I do check else? -Original Message- From: Russell Coker [mailto:[EMAIL PROTECTED]] Sent: Friday, June 22, 2001 10:35 PM To: Cho Yoonbae; [EMAIL PROTECTED] Subject: Re: Hard disk lock down.

Uptime is the sum of two numbers. One number is the average number of processes in "D" state, the other is the average number of programs that are ready to do CPU operations. "D" state processes are processes that are blocked on disk IO. It sounds like there is a device driver error in your system related to disk IO that causes processes to get blocked, and that in this instance 37 programs have become blocked on disk IO. I suggest that you run the command "dmesg" and/or check /var/log/kern.log for information on what went wrong. Also please note that we can't help you solve such problems without information on what kernel version you run. -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page èPÔ ¨¥¶^n&§Êkz«²Ùb²Û y¸àÂ+ajËç-¡û§²æìr¸y:è¹¹^ íiËeËfjË^®X¬¶Ç^n&§¢¸
AT&T public router
A while back, AT&T had a publicly accessible router for doing route lookups and stuff like that. It supposedly knew about the whole world. The special thing about this router was that you didn't need a user name or password to log on with. It just gave you the IOS prompt. I haven't been on this router for a long time and I can't remember the exact name of it. It was something like ip-router.att.net or route.world.att.net. Does anybody remember this thing and have the host name? Thanks. ---==--- ___/``\___ 0100 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Zmailer issues
1. Curently I use zmailer zmailer-ssl 2.99.53pre1 (installed from deb), but I have problem with scheduler - it's dying almost everyday with segfault. Is this a known issue ? In the scheduler's log I've found: action='failed5.' what does it mean ? Also: scheduler: unlink(../queue/D/^<90>0$): No such file or directory There are many such lines, with random garbage after last / 2. I've tried to compile zmailer 2.99.55 (with patch1), but it fails. Are there any unofficial debs with version .54 or .55 ? -=Czaj-nick=-

RE: Multiple DSLs, and switching incoming route upon failure?
Quite frankly, it's dumb as hell to try to half-ass a redundancy solution when you evidently need as close to 100% uptime as you can get. You need to either spend the bucks on leased lines from tier-1 carriers and run BGP (contracting with someone for assistance if you don't have the know-how yet), or preferably you should colocate with a real datacenter and hope they don't go out of business. - jsw
