Hello, I am trying to mess with a prio type qdisc, and must be missing something. Here''s my sample code: tc qdisc add dev eth0 root handle 1: prio tc filter add dev eth0 parent 1:0 prio 1 protocol ip u32 \ match ip dst 208.0.0.0/8 flowid 1:1 tc filter add dev eth0 parent 1:0 prio 3 protocol ip u32 \ match ip dst 0.0.0.0/0 flowid 1:3 I would assume that any traffic going to

Hello, I'm wondering just how critical it really is to turn off oplocks. It appears that not only Windows 2k server, but also Netware 5 and above defaults to having these enabled. I just spoke with two software companies running databases off of file servers (no database server, just MDAC stuff), and they had never heard of it, much less require it to be disabled. Everything I've

Hello Centos People, I have a CentOS 5.3 box that had a total of 5 ethernet cards in it. It functions to share an internet connection with 4 different subnets. All works fine, except I'm noticing that my MRTG traffic graphs are wrong. Further digging with snmpwalk reveal that the order of the ethernet interfaces changes every time the machine is rebooted to a different order. For

Hi How can I control which filter a packet will meet first? I have tried changing the order of applying the tc filter scripts and switching flowid number, but ''protocol ip u32 match ip src <ip net> match ip src 0.0.0.0/0'' always kicks in first? >From my script -------------------- # All traffic - Priority: Low tc filter add dev eth0 parent 1:0 prio 2 protocol ip u32

Hello, I'm trying to set up a samba server for a friend who has a mac. He's running OSX, version 10.2. He's got some really big video editing files that are well in excess of 2gb. We're trying to back these up to the samba server, but it quits right around 2gb. That seems to be a magical number. This is with version 2.2.3 of Samba, and Linux-Mandrake 8.2, ext3 file system. I

Hi gang, I have an application that is sending streaming media to a server. The encoder computer sends an average of 200kbit stream; but for short, 1 second bursts, can hit 400-500kbits. After it does one of these bursts, it reduces its output for another second or two, so that it maintains its average of 200kbits. The problem is that it is sending UDP packets into a DSL link that has a fixed

Hi Gang, I recently rented a server at a datacenter with Centos 5.7 X64, Q9550 Processor, 8GB Ram, and dual 250GB SATA HDs (with 16mb cache). They had loaded it with KVM, and installed a 30-day trial of Virtualizor as the front-end for KVM. I was so impressed with how fasts the guests ran that I want to build a few of these machines for myself. I just installed one: same Q9550 processor, 4GB

I have been trying to get mod_suPHP working on Centos 7's httpd, just as I've done with versions 5 and 6. I found a couple RPMs that others have built, and I even compiled suPHP from source, and got a successful compile. Each time, I can see with phpinfo() that the mod_suPHP module did indeed load, yet I cannot seem to get any script to run in a user other than the default of

Hi all, I have a few CentOS servers that I want to mirror live, to be standby spares. The "spare" machines could be either a different machine (with a different motherboard), or a VM in Vmware server. I've used rsync in the past, which works well for doing it while the machine is live. However, I want the destination to be running different hardware, and have a different IP

Hi Gang, I''m still experiencing some bandwidth starvation with my script (below), so I decided to look at the statistics by using: tc -s qdisc show dev eth0 (where eth0 is the interface I''m trying to rate-limit outbound packets) I get, for example: qdisc sfq 21: quantum 1514b perturb 10sec Sent 133527926 bytes 413260 pkts (dropped 0, overlimits 0) qdisc sfq 20: quantum

Hello, I''ve got a question about routing under the 2.2.15 kernel. I have two connections to the internet, say 1.2.3.4 (gateway 1.2.3.1) and 20.20.20.20 (gateway 20.20.20.1). Currently, it seems I can only set one "default" gateway. So if traffic comes into 1.2.3.4, and my default gw is 20.20.20.1, all the return traffic goes out 20.20.20.1. The weird thing is that if I

Hello, I've got some CentOS 5.3 servers that I want to clone to a backup server, possibly a VM machine. I want this to be done while the server is up, and keep it synced at least once a day. I've done this already by using RSYNC, but here's the twist: the backup machine could be different hardware, and needs to have a different IP address (so they don't conflict). My question:

Hello, I just got back from a datacenter where I installed a new server running CentOS 5.3. I set up a software raid with md0 being /. (Only one mount, didn't split anything up.) I just discovered that instead of raid 1, it did raid 0... Not exactly what I wanted! Probably missed that little check when installing. So now, I need to change this. But since the whole OS is on this raided

Hey gang, I have been trying my hardest to get KVM running on a 32-bit CentOS 5. I know "upstream doesn't support it", but from what I gather, it *is* possible. I've tried downloading the KVM source, but get nailed on compile with: LINK i386-softmmu/qemu make -C /lib/modules/2.6.18-308.1.1.el5PAE/build M=`pwd` \ LINUXINCLUDE="-I`pwd`/include -Iinclude
