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.

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&§¢¸
quota problem.
Hi, I am making ISP server with debian 2.2. There are three package. (ecno:30mb, basic:100mb, premium:300mb) I thought i can solve this problem with quota. first of all, I will make user account with same group name as package name. then apply quota by group. (how about this idea?) but, I have another problem now. if all customer are in 'users' group with 707 home directory permission, there can't access other customers home directory. I have to make three groups(econo, basic, premium).. maybe it will break directory-security.. how can I do? last question, I will serve mysql database account. mysql creates db files in /var/lib/mysql/username with mysql UID. I want to combine this space with customer's home-direcotry quota. is there good idea about these? Have a nice day. yoonbae.
qmail POP3 Problem.
Hi, I am managing two severs with Debian woody distribution. and I am in a trouble with qmail's pop daemon. I'm using following command to start qmail's pop3 daemon. (in /etc/init.d/qmail) sh -c "start-stop-daemon --start --quiet --user root \ --exec /usr/bin/tcpserver -- -H \ 0 pop-3 /usr/sbin/qmail-popup `hostname`.`dnsdomainname` \ /usr/bin/checkpassword /usr/sbin/qmail-pop3d Maildir &" It takes too much time when client try to connect my pop3 server. I can solve this problem with "-H" option. But, one server is slow still. What things are remain I have to check else? Thanks.
tcpserver's response time is too long..
Hi, I'm using qmail with tcpserver. tcpserver's response time is too long. I input like following line, telnet my.server.domain110 +OK <[EMAIL PROTECTED]> it should open pop connection, but it takes too long time than other pop server. but when I try to do like that to localhost, I can see OK message as soon as I input. surely I executed tcpserver with -H option. What things are remain I have to check? I'm using debian woody bye
Re: tcpserver's response time is too long..
Thanks for your article, Alberto. http://cr.yp.to/ucspi-tcp/tcpserver.html -H: Do not look up the remote host name in DNS; remove the environment variable $TCPREMOTEHOST. To avoid loops, you must use this option for servers on TCP port 53. I am using -H option to prevent look up remote hostname, but It takes so long time(even 70-80 sec). I tested on many remote host with different ISP. but result was same. I have managing another server with same debian distribution and qmail. and that server is using -H option, too. but This server's tcpserver is so as fast as commercial POP server. I think I can't solve this proble with only -H option.
