by Steve Lindemann 28 Jun '10

28 Jun '10

Does anyone know when PHP will upgrade to version 5.2.0 or better on 64-bit CentOS 5.5? ...or know where I should look to find out for myself? ...or directions for upgrading PHP from 5.1 to 5.2 on 64-bit (I found directions for 32-bit)? Thanks. -- Steve

Upgrading MySQLdb
by Susan Day 28 Jun '10

28 Jun '10

Hi; I've got MySQLdb installed (bridge to Python) and I can't figure out how to upgrade it. I did a find and got these paths: /usr/lib/python2.6/site-packages/SQLAlchemy-0.6beta2-py2.6.egg/sqlalchemy/dialects/mysql/mysqldb.py /usr/lib/python2.6/site-packages/SQLAlchemy-0.6beta2-py2.6.egg/sqlalchemy/dialects/mysql/mysqldb.pyc I don't have mysql-devel installed, so it wasn't that. Please advise. TIA, Susan

Dual nw card problem again
by Jussi Hirvi 28 Jun '10

28 Jun '10

I have had problems like this before. Probably there is something important that I don't know about routing. Let me introduce to you "Lasso2", a CentOS 4 www server that has been working perfectly well for years. Now I added a second nw card (eth1), automatically using kudzu. I cannot get this dual nw setup to work. The first nw card (eth0) stopped at once working properly, when I added the second card. Hw failure is probably outruled - the connection via eth0 works normally again if I remove the eth1 card and its settings (on reboot with kudzu). There are several symptoms with the dual nw card setup, and I cannot really get to diagnosis. 1) if you ping lasso2 (the problem machine) with the eth0 ip, the ping requests come in ok, but the ping responses leave the machine via eth2 - not good. I don't really know how to analyze routing and how to use ip (the program) to fix it, so please tell me about it. The "ip route show" output looks perfectly normal to me, it is similar to another 2-card machine I have running (though that is Centos v5) [root@lasso2 ~]# ip route show 62.236.221.64/28 dev eth1 proto kernel scope link src 62.236.221.75 62.220.237.96/27 dev eth0 proto kernel scope link src 62.220.237.114 169.254.0.0/16 dev eth1 scope link default via 62.236.221.65 dev eth1 2) if I ping _from_ lasso2 via eth0, it works ok, as long as the ping target is inside the same network segment. I can ping the router. If I try to ping anything beyond that, I get nothing back. This seems to be problem with ARP resolution. It seems that the broadcast address cannot return the ARP data. This is all I can get when I ping 84.20.154.60 via eth0 (representative sample, I hope): [root@lasso2 ~]# tcpdump -i eth0 -n ! port ssh listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 00:01:36.296651 IP 80.221.171.198.2113 > 62.220.237.114.http: S 803184933:803184933(0) win 65535 <mss 1460,nop,wscale 1,nop,nop,sackOK> 00:01:36.654963 IP 65.55.37.179.36910 > 62.220.237.114.http: S 1372599588:1372599588(0) win 8192 <mss 1460,nop,nop,sackOK> 00:01:36.690083 arp who-has 84.20.154.60 tell 62.220.237.114 00:01:37.690145 arp who-has 84.20.154.60 tell 62.220.237.114 The ping itself says: "Destination Host Unreachable". 3) incoming http requests via eth0 do not work at all. I can post tcpdump results, if someone asks me to. This is a production machine, so I cannot really experiment very much. Now I will go and remove the eth1 card for now. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi(a)greenspot.fi * http://www.greenspot.fi

Virtualization as cheap redundancy option?
by Emmanuel Noobadmin 28 Jun '10

28 Jun '10

I'm wondering if virtualization could be used as a cheap redundancy solution for situations which can tolerate a certain amount of downtime. Current recommendations is to run some kind of replication server such as DRBD. The problem here is cost if there are more than one server (or servers running on different OS) to be backed up. I'd basically need to tell my client they need to buy say 2X machines instead of just X. Not really attractive :D So I'm wondering if it would be a good, or likely stupid idea, to run X CentOS machines with VMware. Each running a single instance of CentOS and in at least one case of Windows for MSSQL. So if any of the machines physically fails for whatever reasons not related to disk. I'll just transfer the disk to one of the surviving server or a cold standby and have things running again within say 30~60 minutes needed to check the filesystem, then mount and copy the image. I thought I could also rsync the images so that Server 1 backs up Server 2 image file and Server 2 backs up Server 3 etc in a round robin fashion to make this even faster. But reading up indicates that rsync would attempt to mirror the whole 60gb or 80gb image on any change. Bad idea. So while this is not real time HA but in most situations, they can tolerate an hour's downtime. The cost of the "redundancy" also stays constant no matter how many servers are added to the operation. Any comments on this or is it like just plain stupid because there are better options that are equally cost effective?

Yum archive for PHP greater than 5.2.1 for CentOS 5.4?
by Jobst Schmalenbach 28 Jun '10

28 Jun '10

Whether I like it or not I need to get a version of PHP that is greater than 5.2.1 as the latest SugarCRM version require this and as I am a module developer I need to have one of the later versions of PHP on my machines. Does anyone know of a reliable and good archive for PHP that provides higher versions than the ones supplied by the upstream provider?

Centos to use two ISP concurrently..?
by Roland RoLaNd 28 Jun '10

28 Jun '10

Hi all, I'm currently getting my Centos working as a proxy (squid) on a 2 Mb bandwidth plan that's serving 20 users. it's all good though our need for speed is increasing by the day. soon enough i'll be serving up to 60 user, hence the need to get higher bandwidth though here where the problem is. as i'm using HDSL, 2 Mb is the highest plan available. hence, i need to get 2 HDSL subscriptions, in other words 2 modems/IPs to work with.. ( 2 x 2 Mb) the possibility to use routing table isn't feasible as these two ISP's would only be used for browsing, so routing destinations one way or the other isn't an option. i have two initial thoughts to solve this hope you could straighten me out if they're wrong or suggest something better that your experience lead you to use: 1. setup Openvz on a centos box, get two templates up and running with squid setup on them. each one with a different IP. Each template would be routed to one ISP, and both proxies would be used in child/parent proxy manner so i could use caching from both. and i could split my users in half, 1 half would be using Squid#1 and the other using squid#2. 2. the same squid box have two Nics, with two IPs, one routed to each ISP, i get squid listening to port " 80" on both IPs, and same as above, half of my users would be running on IP#1 and the others on IP#2. do all this make any sense? i'm seeking your help as both ideas does not seem very professional to me, and i doubt that's the optimal solution so any help would be greatly appreciated. thanks , --Roland _________________________________________________________________ Hotmail: Trusted email with Microsoft’s powerful SPAM protection. https://signup.live.com/signup.aspx?id=60969

Stop auditd logging all commands
by Jorge Fábregas 27 Jun '10

27 Jun '10

Hello everyone, I have this box where auditd is logging every command typed on the system onto: /var/log/audit/audit.log Every line looks like: type=USER_TTY msg=audit msg=audit(124433....<snip> msg="command here" ... The strange thing is that I have other similar boxes and I don't see this behavior. I don't see any option in /etc/audit/* or any PAM module triggering it. Is there a way to stop this? I don't want to stop the service since "setroubleshoot" needs it. Any ideas? Thanks! Jorge

Announce list digest ??
by Ron Loftin 27 Jun '10

27 Jun '10

I have just noticed that the main CentOS list ( this list ) is no longer receiving the digest from the CentOS-Announce list. This appears to have stopped about a month ago. Did I miss a notification that this practice would be discontinued, or has something broken? I admit it took me a month to notice that it's been missing, but I did like to see the update notifications in digest form here. -- Ron Loftin reloftin(a)twcny.rr.com "God, root, what is difference ?"

Centos 5.5 on a Toshiba Satellite L1500D - Wireless networking - Realtek 8172
by Frank Cox 27 Jun '10

27 Jun '10

I just installed Centos 5.5 x86_64 on a new Toshiba Satellite L1500D. Everything seems to work (so far) other than the wireless networking; lscpi tells me: 0e:00.0 Network controller: Realtek Semiconductor Co., Ltd. Unknown device 8172 (rev 10) I discovered that I need the realtek driver, so I found and downloaded these: rtl8192se_linux_2.6.0010.1012.2009_64bit.tar.gz rtl8192se_linux_2.6.0017.0507.2010.tar.gz The version dated 2010 appears to be newer, but I can't find one of them that says "64bit" so I'm not sure if I can actually use it or not. I un-tarred it into /usr/src, then copied the contents of the firmware directory to /lib/firmware. When I try to run the make command I get this error. I get the same error regardless of which of the two driver archives I use. What am I doing wrong? Is there an easier way to get this working?
