Networking :: Pertaining To Network Configuration On RHEL?
May 27, 2010
issue in starting up Open view monitoring on couple of linux servers and here is the output from mii-tool looks like.
eth0: 100 Mbit, full duplex, link ok
eth1: 100 Mbit, full duplex, link ok
[code].....
Based on what I understand, eth0 goes to monitoring and the other 2 ethernet cards go to FE. I am not an expert in system administration but would like to know if there is any issues with the above settings/configuration (in fact, im also looking for what do they infer and what is the settings?

I want to create a small network of 3-5 computers. I want to have one computer as my server and have services like NFS, DHCP, NTP, etc. I want to connect it to 2-4 other clients that have the bare minimal installation of linux on them. I would like 1 client computer to have a static ip address and I would like another to receive a dynamic ip address from the server. How would I go about doing all of this without the assistance of GUI's? I want to be able to do all this with the ks.cfg and network config files.

I installed wallpaper-tray and pretty much messed it up in 5 minutes. I enables time change and put 0.1 there just for fun. Next thing I know is that the desktop is changing wallpapers like crazy and almost using all the resources. I can't even click on anything, just see the wallpapers changing. So , i need to find where the config files are stored so i can alter them manually. I tried:
find -iname '*tray*'
it showed a folder ~/.gconf/apps/wp_tray
i deleted the contents of the directory but of no use..

IP : 172.16.152.137
Subnet : 255.255.255.192
Gateway : 172.16.152.191
Primary DNS : 172.16.0.1
[code]....
but after this setup when i restart my network #service network restart while bringing up the eth0 the following message is displayed before [OK] - RTNETLINK answers : Invalid Argument now it seems either this setup is wrong or not sufficient to set up the connection, whenever i try to ping 172.16.0.1 it showing connect : Network is Unreachable

I am booting from a PXE server which runs the anaconda installer l have tried editing the kickstart files and also the pxe cfg file with various options, but have had no luck so far.

I have my new router all set up, and everything is working fine, but I'm having problems adding a password to the network.The network from the wireless router is called "auto dlink" by default, and I've tried through the Gnome interface to add a WEP 40/128-bit key that I generated through a website. As soon as I apply the change to the network, the connection drops, so I click on the "auto dlink" network again to connect, and it successfully does, but it never asks me for the key that I configured it to ask for. After checking the network connections history, it shows me as having connected to two different "auto dlink" networks at different times - the one that I added the key to, which is no longer available, and a new one that I am currently connected to, that does not have a key. Every time I try to make a change to "auto dlink," be it a change to the security or to the network name, the change registers and applies, but the network ceases to be available and is instead replaced by a new, default configuration of "auto dlink."

I'm a Linux n00b (very fluent in Windows, though ) that is attempting to set up a (currently) 3-computer cluster. My server node is a Pentium 4, and my client nodes are a Pentium 4 and a Pentium 3 (whatever I have lying around ) I chose to use OSCAR for my clustering interface and CentOS 5 for my server node OS. Yay. I made it through the installation prerequisites, but when it came to configure the NIC, I got stuck.
I opened the /etc/hosts file, tinkered with it, but something inevitably got screwed up. I can still use the Internet, but it won't let me install OSCAR. Running a system-sanity check returns:
Code:
[root@SurgeonfishR ~]# system-sanity
Checking your system...
Success: ssh-check.pl
Success: tftpboot-check.pl
Success: selinux-check.pl
[Code]...
All I need to know is what the /etc/hosts file should look like for a CentOS 5.4 installation with 1 NIC that is not connected to a domain (only a LAN). It is connected to a router which in turn is connected to my home network (I don't know what to do about that). The hostname should be surgeonfishr and the IP address should be 192.168.0.150.
I know this question is probably really stupid, but I've logged a total of about 10 hours time on Linux...ever. (And 35000 hours on Windows.)

I have few doubts regarding fonts configuration in RHEL 5.4.
Code:
[vinay@linuxcoe4 fonts]$ cd /usr/share/X11/fonts
[vinay@linuxcoe4 fonts]$ ls
100dpi 75dpi encodings misc TTF Type1 util
[code]....
Also there is no fonts.dir file, which describes fonts under a specific fonts directory in /usr/share/fonts tree. But we can find fonts.dir or fonts.scale file under /usr/share/X11/fonts/ tree. Does files under /usr/share/fonts tree are not dependent on fonts.dir ?

Friends i got an opertunity to configure ddns in my office.I already configured staic dns in linux, but this is the first time iam configuring ddns.I just configured ddns in rhel 5.2 in my office.So far every thing working fine,dhcp is giving ip address to the clients and both forward and reverse dns database is updating.
1) In windows we can use flushdns and registerdns commands to update the dns database, like this any command is in linux to update client details in dns database?
2)how to restrict multiple client entries keeping in dhcp database.
3)if i change client hostname it is not updating the dns database,it is keeping the old one.

I believe that SU log messages are supposed to be appended to /var/log/messages but I'm not getting any log entries. I edited the /etc/syslog.conf and added the line below
su.* /var/log/sulog
Then ran /etc/rc.d/init.d/syslog restart (I also ran this prior to editing the syslog.conf file just in case). I'm still not getting any SU log messages.

I have and RHEL5.4 conecceted to an SAN HSV200. When I present a LUN to it, In system-confg-lvm gui appears a device like /dev/mapth/mapth0 (that�s the correct device to multipath) and other like /dev/sda or /dev/dm-N, as uninitialized entities. How could I configure to not display this device (/dev/sda) and prevent human errors?
This is the things I need:
1- I want (if it is posible...) to disappear the part where it says "uninitialized entities"
2- Is It necesary mantain the partitioning done to default (like /dev/mapper/mpath0p1) with device-mapper-multipath (kpartx command)? or Can I delete it without future problems?
This is the actual configuration that I have:
1- /etc/lvm/lvm.conf
Code:
preferred_names = [ "^/dev/mpath/", "^/dev/mapper/mpath", "^/dev/[hs]d" ]
filter = [ "a/dev/mapper/mpath.*/","a/dev/cciss/.*/","r/.*/" ]
2- /etc/multipath.conf
Code:
#blacklist {
# devnode "*"
#}
[code].....

Similar to the linux command "chattr +i filename", I would sure like to set my eth0 interface immutable. so once I assign the eth0 interface's IP and gateway, make it stay set until I say otherwise.
this way, I can run dhclient or Networkmanager on another interface without having to fret that it may alter this interface. is there something out there that can do this?

I have three 10Gb Fibre PCI ethernet cards and 2 onboard gigabit ports. The two gigabit ports always seem to be mapped to eth0 and eth1. I set the network configuration for eth2, eth3, and eth4 in the /etc/sysconfig/network-scripts/ifcfg-eth# files. Would the NIC in PCI slot 1 always be mapped to eth2, NIC in slot 2 mapped to eth3, and NIC in slot 3 always mapped to eth4?

One monitor is working fine but the display is not coming on other monitor. I guess no problem in monitor because I swapped the cable to check the individual monitor. When I try to install the new driver its giving GCC-VERSION-CHECK while installing. And I do not think I have to install the new driver because it has already one. What should I do to configure the dual monitor. Do I have to edit any configuration file.
My system configuration details are below.
Redhat version : Redhat Enterprise Linux WS release 3 (Taroon update 4)
Driver in SRBC 26: NVIDIA-LINUX-x86_64-1.0-7664-pkg2.run
Nvidia card model : Quadro fx p171
Bios version of Nvidia : 4.35.20.23.07
p/n : 900-50171-0400-0000K

Recently, I had the courage of installing Fedora 11 on my laptop while risking of trashing my Windows XP. Fortunately, the installation went fine and windows and fedora seems to be working together. But I needed to reinstall Fedora because I didn't do the partitioning right. After that the problem arises. I couldn't connect to the wlan. The first installation it was working fine. Now I can't. I select the network, enter the password and then it just says "Disconnected" or something like that then nothing else happens. So I had to reinstall it again thinking I did something wrong on the installation. But still it wasn't working. But it seems to be working when I boot from the live cd. I must have messed up my network configuration.

The other day I was using BitTornado and it was running so slow it was almost unholy. After some research I found out that if the yellow light was on it means I couldn't receive any incoming connections and had to open some ports on the firewall. That, my friends, is not the problem. I tried to manually open up the bittorrent port and did some other things that I can't quite remember but eventually I accidentally killed all bittorrent functionality on my laptop.
Is there any way I can reset my network and ports back to the default settings or am I utterly screwed? I'd really prefer not to have to reinstall my whole OS just to fix my bittorrent or worse, have to download on Vista *shudders*. I'd rather go back to my uber-slow bittorrent than none at all. I've tried everything I can think of, even the godlike might of Google couldn't get me out of this one. Now I am forced to bother you, all because I wanted to see a damn sci-fi film from Switzerland (Cargo[2009]).

For Ubuntu 10.04, I can configure the network by "Network Connections". This configuration is done by doing the following operation sequences(System->Preferences->Network Connections->wired->auto eth0). Then I can connet to and browse the internet. If I type the command "ifconfig", I can see the ip I configured for eth0. Part of the content is as blow:
Quote:
ifconfig
eth0
inet addr:192.168.28.31 Bcast:192.168.28.255 Mask:255.255.255.0
But in the "interfaces" file, there is no eth0 content. The whole content is simply as below:
Quote:
cat /etc/network/interfaces
auto lo
iface lo inet loopback
I think there should be other files that keep the eth0 configuration content.
