How many users do you have? One detriment I've found is that much of it's backend relies on Java and requires some serious tuning for installations with a large user base. Also, the logging facilities use MySQL and can cause huge performance issues especially when running consolidations/stat generations. Tim Nelson Systems/Network Support Rockbochs Inc.

Can't yum erase/install an app
by Robert Moskowitz 07 Jan '09

07 Jan '09

I am switching the box that I did the HIPL rpm builds over to running from rpms built directly by the HIPL team (http://infrahip.hiit.fi/hipl/release/1.0.4/) I did the 'make uninstall' and then 'yum install hipl-all', but the hipl-firewall rpm did not install. Seems like I have a mess on my system with the various hipfw files. I 'manually' deleted a bunch of them (perhaps a mistake), and then tried 'yum install hipl-firewall' and it reported that it was installed. So I tried a 'yum erase hipl-firewall' and got two errors: hipfw: unrecognized service error reading information on service hipfw: No such file or directory Then I get a 'Removed: hipl-firewall.i386 0:1.0.4-1' and a 'Complete!'. I then do a 'yum install hipl-firewall' and get that it is installed and there is nothing to do.... Well, it is not installed, but there is something in yum that says it is installed. What to do? man yum does not show any options to force the install. So how do I get around this foobar?

Bash cgi upload form

Anyone have a function or script for uploading files from a web browser with a bash script? I know this is possible to do with Perl, I'm wondering if the same is possible using only bash.

xCache install error ($PHP_AUTOCONF?)
by James Bensley 07 Jan '09

07 Jan '09

Hey Guys I'm trying to install xcache on our web server (php optcode cacher) but I am having the following error. I have download the xcache tar ball, unzipped and when in the unzipped directory attempting to run phpize but it fails with the following error: [root@server1882 xcache-1.2.2]# phpize Configuring for: PHP Api Version: 20041225 Zend Module Api No: 20060613 Zend Extension Api No: 220060519 Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable is set correctly and then rerun this script. Ok, $PHP_AUTOCONF doesn't exist so I made it in my bash profile and set to it /usr/local/bin where autoconf is installed too. After logging in and out it didn't work although the environment variable had correct exported. I checked online some people have mentioned you need libtool installed aswell but I have that too (and automake before you ask, all three are installed and have symbolic links in /usr/bin to /usr/local/bin) but this still isn't working and I can't work it out. Can anyone shed any light on this for me? Thanks for reading listee's!

LDAP Authentication to Lotus Domino?
by Charles Richards 07 Jan '09

07 Jan '09

Has anybody done any authentication to Lotus Domino using LDAP? I selected LDAP options in the "authconfig-tui" application, per the documentation here: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-ldap-pam.html when I try to query the directory for user information though, I get no results using the ldapsearch command [root@ldapclient ~]# ldapsearch -x uid=crichards # extended LDIF # # LDAPv3 # base <> with scope subtree # filter: uid=crichards # requesting: ALL # # search result search: 2 result: 0 Success # numResponses: 1 I'm not quite sure what I'm missing, as I can manually query the directory for, say, a uid, with the "ldapsearch" command with options specified and it returns the correct info from the directory. [root@ldapclient ~]# ldapsearch -H ldap://domino.mydomain.com -W -D Charles\ Richards -x uid=crichards Enter LDAP Password: **** # extended LDIF # # LDAPv3 # base <> with scope subtree # filter: uid=crichards # requesting: ALL # # Charles Richards, NewPush dn: CN=Charles Richards,O=MyDomain cn: Charles Richards mail: CRichards(a)mydomain.com displayname: Charles Richards/MyDomain messagestorage: 1 encryptincomingmail: 0 roaminguser: 0 <snip> ... I have a feeling I'm missing something in my /etc/ldap.conf regarding how I'm binding to the directory (I've tried using my CN=Charles Richards for the binddn and rootbinddn to no avail...) Any tips or info are greatly appreciated! Thanks, Charles Richards richardsc(a)gmail.com charlesrichards.net

What does system-config-netboot do???
by clemens＠dwf.com 07 Jan '09

07 Jan '09

Having given up on getting system-config-netboot to work (reading the pointers I have received to the wiki, say it is broken), I have the simple question "What is it suposed to do???" I have tried to look at the code, but its written in python and I cant follow the logic. Im sure I can easily do whatever is necessary at the command line If I just knew what it was trying to do with its cute user interface (and dont get me started on broken, cute, user interfaces...) -- Reg.Clemens reg(a)dwf.com

High softirq usage in Centos 5
by Oguz Yilmaz 07 Jan '09

07 Jan '09

Hi, I have a machine under heavy network traffic. Kernel is Centos kernel 2.6.18 SMP 32 bit. Ethernets are 05:00.0 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01) 05:00.1 Ethernet controller: Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) (rev 01) 06:01.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) 06:02.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) The mainboard is with Intel 5000 series chipset Asus board. When I use 2.6.9 kernel with the same location and traffic I have had no softirq usage. Also in 2.4 Centos 3 machine I have had no softirq usage. With the same location and traffic I have softirq usage %25: Cpu0 : 2.0%us, 2.0%sy, 0.0%ni, 71.3%id, 0.0%wa, 2.7%hi, 22.0%si, 0.0%st Cpu1 : 1.0%us, 1.3%sy, 0.0%ni, 79.7%id, 0.0%wa, 1.3%hi, 16.6%si, 0.0%st I have no extra parameters in grub.conf. Is it a known problem? What do you suggest?
