Networking :: RHEL 5.4 Can't Reach Any External Host Or Even Ping Localhost

May 27, 2010

This is a RHEL 5.4 install. I did a fairly routine install setting up a static IP address of, a subnet mask of, and a gateway of with the standard DNS setup for this network. These are all standard network setting for this network and otherwise work fine on other systems. The IP, gateway, and subnetmask all appear correctly on all relevant configuration files. This server can not ping any other system on the network and can not ping its default gateway. No other systems can ping this one either. Also this system can not ping "localhost" or its own hostname. The hosts file contains the line:


I can ping and and it works fine. Also the firewall is disabled. I know I probably can't get a straight forward fix with the information I have on hand right now, I'm more of a Debian guy, so there might be some Red Hat intricacies I'm not familiar with. I think I had a CentOS install some months back that had this issue and I don't remember how I fixed it, or if I even did. I might have just replaced it with Debian. That's unfortunately not an option this time around since it's not my box.

CentOS 5 :: Pirut/yum: RHEL 5.1 - Maintain An Unregistered RHEL Box?

Feb 16, 2010

A client has sent me an RHEL 5.1 box for me to do some work on, but it's not registered with Red Hat. This is causing me problems, because it's a minimal installation, and I need some more dev software.My immediate reaction was to install various bits (emacs, and so on) from my Centos 5(.0) DVD.The base RHEL system only had one (disabled) repo entry,so I added a yum DVD repo entry in yum.conf.d.

This looked good to start with, but it doesn't work. Something in RHEL's pirut/yum/rpm/whatever is getting confused, and can't work out what is/isn't installed.

Question - how do you maintain an unregistered RHEL box? Has RH done something to make life difficult? Is my problem simply that I'm using a Centos 5.0 DVD, instead of Centos 5.1? Am I stuck with downloading lots of rpms from the net and doing everything manually? I really don't want to do that.

Red Hat :: Duplicating A RHEL 5.1 32bit Server On RHEL 5.4 64 Bit

Dec 9, 2009

I have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.

Server :: 4 Virtual Disk On AX4-5i / RHEL Showing 16 Partitions

Jul 29, 2010

I have 4 virtual disk on AX4-5i. RHEL for some reason shows 16 partitions in /proc/partitions. I got lot-lot of IO errors in dmesg. Some of those 16 partitions "work", others just give (on using fdisk for example): Unable to read /dev/sdb. On EMC I have 4 ports, so it might be somehow releated to this.

I've googled and read docs but got no idea what to do. Any experiences with EMC/RHEL/iSCSI - I just don't understand where those 16 (and half of them not working/giving lotof errors) come from? For example Citrix Xen on similar network conf can see/use same EMC thoughr iSCSI nicely. SO there should'nt be network/auth issues (not using CHAP btw). I got feeling that problem is on RHEL iscsi conf side.

Red Hat :: How To Dual Boot RHEL 5.2 And RHEL 5.4

Sep 25, 2009

Environment:RHEL 5.2 and 5.4 AP x86_64, 2 drives (sda, sdb), installing without optional features like clustering and virtualization. I have tried this for a couple of days now and just can't get it to work. My goal is to take the RHEL 5.2 DVD and RHEL 5.4 DVD and install them on separate drives of the same machine. I want the grub menu to give me a choice. I prefer to understand the steps and choices offered me by the install dialog to do this rather than fiddle with grub.conf. If that is not possible, I will write up the bug.

So far, I just get the the error 13 when trying to start the grub added second OS. I have read elsewhere that "Anaconda frequently recognizes the other operating system and sets up grub so you can boot from either operating system". That would be nice. The install dialog lets me choose a drive to install to. I have figured out that I need to check "review and modify partitioning layout" to enter the advanced grub choices. Do I have it install a boot loader for the 1st OS? Trying to add the 1st OS during the second OS install creates a grub conf with no kernel line in the added boot stanza.
