Re: [CentOS] Static routing on CentOS
by Steven Tardy 26 Feb '14

Something on that subnet will need to know how to accept and forward the packet to the correct destination: the router/gw will still have to have a route added. > On Feb 26, 2014, at 9:24 AM, Steve Clark <sclark(a)netwolves.com> wrote: > > Actually you can by adding a route via the interface > ip r a 20.20.20.0/24 dev eth0

Static routing on CentOS
by Jatin Davey 26 Feb '14

26 Feb '14

Hi All I have two hosts. Host A and Host B Host A routing table ------------------------ [root@localhost ~]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.29.110.0 172.29.109.1 255.255.255.0 UG 0 0 0 eth0 172.29.109.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 172.29.109.1 0.0.0.0 UG 0 0 0 eth0 HOST A IP address : 172.29.109.254 Host B routing table ------------------------- [jatin@localhost ~]$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.29.110.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 20.20.20.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 0.0.0.0 172.29.110.1 0.0.0.0 UG 0 0 0 eth0 HOST B Ip address : 172.29.110.93 Host B basically houses some simulated devices which are configured in the ip address range of 20.20.20.1 to 20.20.20.254. The netmask being used here is 255.255.255.0 I want to configure a static route on HOST A so that they can reach the simulated devices running on HOST B which are in the ip address range 20.20.20.1-20.20.20.254 , I am trying the following command but it does not configure the static route for me. [root@localhost ~]# route add -net 20.20.20.0 netmask 255.255.255.0 gw 172.29.110.93 SIOCADDRT: Network is unreachable Any help is greatly appreciated. Thanks Jatin

OT: Howto to capture taskset output command
by C. L. Martinez 26 Feb '14

26 Feb '14

Hi all, I am trying to set processor affinity for a specific process using a shell script without result. Script: #!/bin/sh -x cpu_affinity_ok="2" cpu_affinity="taskset -p -c `cat /tmp/test.pid` | awk '{print $6}'" if [ -f /tmp/test.pid ]; then if [ "$cpu_affinity" == "$cpu_affinity_ok" ]; then exit 0 else taskset -p -c 2 `cat /tmp/test.pid` fi fi This script doesn't works: [root@cos01 bin]# taskset -p -c 27756 pid 27756's current affinity list: 2 Excecuting script: [root@cos01 bin]# ./my_cpu_affinitty + cpu_affinity_ok=2 ++ cat /tmp/test.pid + cpu_affinity='taskset -p -c 27756 | awk '\''{print }'\''' + '[' -f /tmp/test.pid ']' + '[' 'taskset -p -c 27756 | awk '\''{print }'\''' == 2 ']' ++ cat /tmp/test.pid + taskset -p -c 2 27756 pid 27756's current affinity list: 2 pid 27756's new affinity list: 2 As you can see, function compare under "if" statement doesn't works ... Any idea?? Thanks.

Upgrading to CentOS 6
by Styma, Robert E (Robert) 26 Feb '14

26 Feb '14

I recently built a CentOS 6 system as my main machine at home. With a bit of help from members of this list, it is now working better than the machine it replaced (RIP). The new machine works so well, that I would like to convert some CentOS 5 machines to CentOS6. I did some research on the web and the new install is still considered the proper way to upgrade CentOS. Same as Fedora and RHEL. The question becomes, "What makes the Ubuntu developers so clever that they can do major upgrades through their apt based update system?" There must be some sort of gotcha or tradeoff involved in allowing this. Does anyone have any insights on why they can get away with this while CentOS cannot?

system hangs
by m.roth＠5-cent.us 26 Feb '14

26 Feb '14

Every so often, one of our servers will go into what I can only describe as an undefined state: it pings, but there's zero access - you can't ssh in, and if I go plug a keyboard and monitor into the server itself, you can see the monitor's live, it's not the "monitor turned off" color, but there is zero response to the keyboard. The upshot is that I wind up having to power cycle it. Well, it just happened again on one of our servers Friday evening, as I found this morning. Looking at the logs this morning, I see that sar last shows 10:20:01 PM all 34.38 0.00 8.29 0.00 0.00 57.33 On of my users dropped me an email at 22:45 that it was "off", and the last things I see in /var/log/messages are one of those annoying Feb 21 22:26:23 <server> kernel: INFO: task perl:20596 blocked for more than 120 seconds. Feb 21 22:26:23 <server> kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. I also see Feb 21 22:26:23 <server> kernel: perl D ffffffff80158250 0 20596 20557 which, as I just found by googling perl NOTLD, means that this is in a kernel uninterruptable state In addition, in the stack trace, some nfs messages Feb 21 22:26:23 <server> kernel: [<ffffffff886b58d1>] :nfs:nfs_wait_bit_uninterruptible+0x0/0xd So, it *appears* to be either an NFS issue, or a NIC issue. The user's home directory server is CentOS running 6.5, and the server that hung is 5.10. Mount on the formerly hung server, su-d to his account shows merely nfs, so I'm guessing it's NFS3. Looking at lsmod and /var/log/dmesg, I see it's running the tg3 NIC driver. Anyone else seeing this, and if so, any thoughts on the matter? Note that I've had this on Penguins, which are all Supermicro, and they're using the igb NIC driver, but the one this past weekend is a Dell, so it's not just one system. mark

Migration from 32 to 64 bits
by Fabrizio Di Carlo 25 Feb '14

25 Feb '14

Hello to all, currently I have CentOS 6.4 32 bit, very simple setup on my notebook, I want to migrate it from 32 to 64 bits cause I want to play with some VMs etc etc. Do you have some suggestions on how to do backup of folders (mainly I have 1 user) or just copy the user folder and stop?

To add to Les' points, Fedora has offered in place upgrade, going at least as far back as FC1 -> FC2.
