Hi All, Was wondering if you could help me out. At work we are running CentOS 4.2 as our mailserver/firewall. The script in question is /etc/rc3.d/S08iptables. As this starts before the network adapters are set up, it hoses our iptables script resulting in denying our internal hosts internet access. What I would like to do is mv the script to /etc/rc3.d/S11iptables so the the

I'm replacing an ancient Solaris 'ipf' firewall/router with a brand new CentOS 6.3 system. In the olden days, I successfully used the attached iptables script (as /etc/rc.local) on Red Hat 5.x systems, but this doesn't seem to be quite working on the new system. Specifically, while it seems to be routing ok, you cannot connect to anything on the inside net (e.g., with ssh or

Dear Srs, I'm trying to automount an iSCSI device at system startup, this is the configuration: - CentOS 5.1, with kernel 2.6.18-53.1.14.el5PAE, i686 arch - iscsi-initiator-utils 6.2.0.865-0.8.el5 - iSCSI target is a Infortrend A16E-G2130-4 I have solved the "initial_login_retry_max" problem [1] and Open- iSCSI logs into Infortrend target without problems, with 10 retries in

I have been trying to boot Xen guest (Fedora Core 6 - linux version 2.6.18) from NFS server but I kept encountering a problem despite using ramdisk or not. Key items in my config file are as follows: ================================================= kernel = "/root/Xen/xen-3.1.0-src/linux-2.6.18-xenU2/vmlinuz" # Optional ramdisk. # ramdisk = "/boot/initrd-2.6.18-xenU2.img"

Hello After i have upgraded to centos 4.4 i have a problem during the boot with NFS, CentOS can't mount NFS shares: Oct 2 11:47:28 s2 mount: mount: mount to NFS server '192.168.140.13' failed: Oct 2 11:47:28 s2 mount: System Error: No route to host.

Hi, What's the correct way to change configuration parameters for an iSCSI device? For example I/O scheduler, max_sectors_kb, etc... I could add commands to the S99local script: echo noop > /sys/block/sdb/queue/scheduler echo 64 > /sys/block/sdb/queue/max_hw_sectors_kb Unfortunately, iSCSI device names might change from sdb to, say, sdc (server reboot, iSCSI target reconnection).

I've just test an ATI FirePro 2460 graphics card on CentOS 6.4. It connects 4 monitors. It worked with the standard radeon driver. I was able to arrange the monitors into my preferred configuration (as a square array, 1 upper left, 2 lower left, 3 lower right, 4 upper right) simply by clicking System -> Preferences -> Display, and then moving the four monitor images. This creates the

I have an ethernet device in my lan with a primary address 192.168.5.205 and a secondary address .217. I added the secondary address after network startup established the primary address by an ip addr add command: # ip addr add 192.168.5.217/24 broadcast 192.168.5.255 dev eth0 # ip addr show ... 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether

I can't figure this one out. There's a Belken USB->Ethernet adapter as eth2 on my server. After a reboot it doesn't communicate with anything ever though it's up: ipaddress is 68.15.6.136 gateway is 68.15.6.129 # ifconfig eth2 eth2 Link encap:Ethernet HWaddr 00:05:1B:00:52:BF inet addr:68.15.6.136 Bcast:68.15.6.191 Mask:255.255.255.192 inet6

I am trying to create a samba mount to be mounted automatically on a Redhat 7.2 machine. I can mount the drive from the command line, but would like to have the drive mount on boot. I have added it to /etc/fstab, and get prompted for a password when I run mount on it from the command line. I know it is possible to pass the "password" option, or the "credentials" option to

Hi everyone, I''ve been working with Mongrel, Mongrel_cluster and Apache and it is great. However, I can''t get mongrel_cluster to start at boot time. I followed the instructions from http://mongrel.rubyforge.org/docs/mongrel_cluster.html (On Boot Initialization Setup) and mongrel_cluster does not start after rebooting the machine. I made sure that the shebang line is correct and

Hi all, Has anyone seen something like this before: I want to use a laptop as a KVM console. Basically when a technician goes to one of our datacentres, or clients he has to look for a free LCD, keyboard & mouse to connect to a server (no network access, reinstall, troubleshoot failed kernel / HDD, etc). And then hopefully there's an open power socker in that cabinet. So I'm

I am migrating off of a 40GIG hda to a new 160GIG sda disk. I plan on installing 4.2 from scratch. But after that what is the correct way do transfer all the data from hda (home partition really) to the new sda home partition? I presume there is just a couple files in /etc to restore also. Like hosts, passwd. Anything else? Other suggestions welcome also. this is my first time migrating to a

Dear All, I used to use CentOS 6 on my desktop without any issues until this morning. Booting stops after the libvirt-guests and certmonger init script. I don't start any guests at boot-time. In rc3.d is only the S99local script after certmongers. Normally, I just suspend this box, so I'm not sure when I rebooted it last time successfully. Does anyone happen to know why booting stops? I

Does anyone know of a cheap temperature sensor that will work with Linux? I don't need a fancy monitoring appliance, I just want a simple sensor that I can connect to one of my monitoring servers to let me know if the server room is getting hot. -- Bowie

I have an old dell 2450 that was running kernel 2.6.18-308.1.1.el5 I then upgraded it via yum to 2.6.18-308.1.1.el5. Now when the server boots to the new kernel, 2.6.18-308.1.1.el5 it hangs on "starting iSCSI" and the weird thing is when I tried to switch back to the older 2.6.18-308.1.1.el5 kernel it works fine but the network script fails to start. I'm not really sure what I should

Hi -- My CentOS 5.8 server crashed, leaving no clue why. The last entry in /var/log/messages is a dhcpd notice around 4:00am, followed by the restart message when I rebooted. The only clue that I have is that the fan was running full speed when I restarted it. The fan slowed to normal speed. Any ideas what I can do to find out the cause? -- Michael Eager eager at eagercon.com 1960 Park

A CentOS 6.3 box ("host") runs several KVM virtual machines, each of which has two interfaces attached to the two bridges br1 and br2 (and each thus has two IP's; one on 192.168.0.0/22 and one on 192.168.4.0/22); net.ipv4.ip_forward on the host is 1. Simplified diagram: host +---------------+ |
