CentOS based router dropping connections
by Jesse Cantara 26 Jul '07

26 Jul '07

Hello, I am trying to figure out a problem I'm having using CentOS on a machine as a router. The short story is: any traffic routed through the router seems to get disconnected at random occasionally. The hardware setup is: I have two switches, the router sits between them, the webserver on the LAN switch. The machine I'm using for the router is a Dell 860 1U rackmount with two NICs, one NIC on the internet, one NIC on the LAN. The routing setup is: I'm using IPTABLES for routing, with the following command: iptables -t nat -A PREROUTING -p tcp -m tcp -i eth1 --dport 6680 -j DNAT --to 192.168.1.10:80 Basically, I'm forwarding port 6680 on to the webserver (.10) on the LAN. What I have tested so far: If I'm at the router, I can download files from the webserver just fine, so the webserver setup and physical connection is OK. If I'm at the router, I can download files from the internet just fine, so the physical connection to the outside is OK as well. If I'm on the outside of the router (on the internet) I can download files directly from the router just fine. The issue is when I try to download a file from the webserver via the router (port 6680). It will work sometimes, but other times it will randomly disconnect me, at random points during the download. Watching the traffic on a packet-sniffer shows that right before the download fails, my client computer trying to download the file keeps resending "ACK" messages, the router keeps sending the next sequence of packets, and eventually the router sends a bunch of "RST" packets. There aren't any strange messages in /var/log/messages or dmesg in either the router or the webserver I need some help diagnosing this problem. Here's some info about the router: CentOS 5 latest kernel 2.6.18-8.1.8.el5 iptables v1.3.5 I've tried testing as much as I can before asking for help, but I'm at the end of what I know to try. Any leads as to where to look to diagnose, or what might cause this would help. Thanks in advance, -Jesse

And that is the clue I needed. My base repository is still coming from the CentOS 4.4 CD isos via mrepo. I need to upgrade those isos to 4.5 and then everything should work properly. -- Bowie

Problems printing multi-page emails to SMB printer HP1120C
by Andrew Allen 26 Jul '07

26 Jul '07

I have a SMB printer on my network (HP1120C connected to a Windows XP machine). CUPS test page printed OK (CUPS v1.1.x) so printer appears to be installed and set up correctly for printing from my CentOS 5 machine. Problem is when I try to print multi-page emails, I get an unspecified error after printing the first page and it won't print any more pages - in fact it just keeps printing the first page and also rubbish! The print log on my CentOS machine says the printing is completed but on the Windows machine it says there is an error. I never had this problem when I was using RedHat9 - any suggestions would be much appreciated. Andy

SHOULD I NEED TO RECOMPILE THE KERNEL ?
by Indunil Jayasooriya 26 Jul '07

26 Jul '07

Hi, I am still runnig Redhat 9 box with sendmail and squid. It is quite slow. It has only 128 MB RAM. So I upgraded it to 512 MB RAM. Now, It is running with 512 MB RAM. But, It is still slow. No progress has been achived. Some users say it is slower than before. Actually, I also have noticed it is NOW SLOWER than before. WHY IS THAT? SHOULD I NEED TO RECOMPILE THE KERNEL as I installed a new 512 MB RAM ? help needed? -- Thank you Indunil Jayasooriya

If you are using Bind as your caching name server, please take note. http://www.net-security.org/secworld.php?id=5366 I use DJB's dnscache so I could care less.

NFS filesystem recommendations please (and problems with XFS)
by Patrick - South Valley Internet 25 Jul '07

25 Jul '07

Hello all, I am implementing a new mail server into our environment consisting of three machines - two Dell Opterons that will act as load balanced Postfix servers, and a 1.5TB RAID10 NFS server. All three machines are running CentOS 4.5. Since the NFS is going to be used for only mail, I was kicking around the idea to use XFS. I have CentOS installed on an ext3 partition, and with the leftover space on the NFS I created an XFS partition. I tried to implement XFS into the kernel, and was coming across some issues. Even after installing xfprogs and xfsprogs-devel, and issuing the command: yum --enable-plusrepos install kernel I booted up the kernel and still could not mount my XFS share. I keep getting this error: mount: fs type xfs not supported by kernel After googling around (and not finding out how to get XFS enabled in the kernel), people had some concerns about using XFS due to issues and it being about as fast as ext3. Also people said that I might run into issues with XFS if I run NFS+lvm+xfs+md but I'm not sure if I run lvm and md and if that applies to me. I found this benchmarking blog someone wrote that compares the speeds in Ubuntu with all the filesystems in a Postfix server environment (although it's not NFS): http://piao-tech.blogspot.com/2007/04/file-system-benchmarks-for-postfix-ma… With all this said, I'd like to use XFS, if it indeed is going to be the fastest for the solution I want to implement. If you guys can help me get that installed by telling me what I need - great! If you think XFS isn't going to work as efficiently and fast as I want it to, and there is another filesystem (such as ext3) that will be more stable and just as fast in my setup, I'm all ears. Thanks everyone in advance. Patrick

Yum missing dependency
by Bowie Bailey 25 Jul '07

25 Jul '07

I haven't run any updates on my systems recently, but now I'm trying to get them up to date again. When I run a yum update, I get this error: Error: Missing Dependency: initscripts >= 7.93.26.EL-1 is needed by package httpd I did a Google search, but I didn't find anything relating directly to CentOS or RHEL and there was no fix suggested. If it makes a difference, I am running the update against a newly created mrepo repository. Any suggestions? -- Bowie
