Web Hosting :: SuSE Vs. RHEL

Does Anyone Use SUSE Linux
I have been trying to compare Red Hat to SUSE Linux, and can't really come to a definitive solution. I can't seem to find anyone that uses SUSE (Well, hardly anyway), but I found out that they have over double to market share that Red Hat has so somebody is definitely using them. I also noticed that SUSE is cheaper too.

Based on your experiences, what are some of the pros / cons both ways? Who offers better product training (I wan't to get certified directly)? Who has better product support? Is AppArmor better than SELinux?

By the way, I am only looking for commercial linux distributions. Specifically companies that offer product training.

Postfix On Suse Is Not Working
I have a server which runs suse linux on it. Postfix is already installed on it.
But, the problem is i am not able to send mail using root. I mean using mail -v command.

I could see the following in mail logs. I know 2 files main.cf and master.cf are there.

Not, sure what to change and how.

Nov 21 21:17:56 CSIDB3 postfix/smtp[14577]: connect to mx3.domain.com [x.x.x.x]: Connection timed out (port 25)
Nov 21 21:17:56 CSIDB3 postfix/smtp[14577]: 61715223EE: to=<sabarish@domain.com>, relay=none, delay=30, status=deferred (connect to mx3.domain.com[x.x.x.x]: Connection timed out)

The same thing happens will Gmail also. I think outgoing mail is not working at all.

Nov 21 20:27:41 CSIDB3 postfix/smtp[13907]: connect to gsmtp183.google.com[64.233.183.27]: Connection timed out (port 25)

RHEL 4 Or 5
Will you use RHEL 4 or 5? Is there any great differences between them?

I want to use the newer version, but helix server [url] requires RHEL 4 to run, so I am just thinking whether I should use RHEL 4 or 5.

SusE / MAC X-Server Backup
I'm working with a local startup and we are looking into potential backup solutions. We have roughly 9 servers all running some variation of susE linux (some straight susE and some X Server which runs off susE).

We are needing a backup solution that will allow us to securely get data off the servers on a regular interval. We are unable to move the data off site as we are running on a single T1 line with moderate utilization, certainly not enough BW to go off site.

Suse, Debian, Fedora Or CentOS
I will be dropping my shared-hosting plan and ordering a small VPS as soon as I can decide on which operating sytem to use. It seems that most companies offer the following choices: Suse, Debian, Fedora and CentOS.

I freely admit that I am a full-fledged n00b when it comes to linux and will be learning as I go, the problem is I just don't know where to start because I'm not familiar with any of them. I have at least heard of Suse, Debian and Fedora before, but didn't even know this CentOS existed until yesterday... and yet, it seems to be one of the more popular choices.

So I was wondering if some of you seasoned VPS veterans here could recommend an OS, tell me what the differences are, or otherwise share any experience you might have with any of them.

64 Bit RHEL
Going to order a new server fairly soon, and I'm facing the tough question if I should go with 64-bit or stay with the "classic" 32 bits. My operating system of choice is Red Hat Enterprise 4.

From the research I've done, RHEL 4 (64 bits) should come with dual libraries that would allow running 32 bit and 64 bit applications under the same 64 bit operating system. Sounds great, and if it comes with an overall performance boost I am all for it.

But I've also heard that that's only the theory - in reality, I could end up banging my head against the screen for uncounted hours because compatibility still isn't as good as it's supposed to be. I don't plan to run Plesk or Cpanel, but I still don't want to get into hot water with other applications I've been using on my current 32-bit server.

All in all it's intimidated me quite a bit, so I'd probably go with 32 bits this time around, just to be on the safe side. Then again, I'm still having an eye on the possible performance boost, so dunno. Does anyone have an idea what's the latest on this? 64 bit already safe for the non-experimental-minded, or bleeding edge and stay away from?

Setting Up A Domain Name SUSE 10 Runing From Home
I've got SUSE 10 loaded and installed at home.

My ISP service is highspeed from Comcast (speed right now not an issue), I would like to setup a domain name on the box to play around with - nothing serious yet.

I have several domain names purchased (Wildwest & Enom) and would like to use one of those on this box, or even more domains at a later day.

Time Auto Modified At RHEL Server
I have a problem with time at one RHEL 4 server, it is a plain box, and from time to time the time (hours) seems to be auto modified, no one is touching the box and then from once it got modified to a few hours less than what we specified, to change time and date we always use:

Code:
date --set "2007-10-24 13:35"
hwclock --set --date="2007-10-24 13:35"

The only thing that I noted is that ntpd daemon was running, while in the rest of our plain box it is not running, maybe this is the reason the system is auto chaning the time?

Hypertown RedHat RHEL 5.2 Server Has Been Going Down Everyday
For the past two weeks, our Hypertown RedHat RHEL 5.2 server has been going down everyday because of a wierd Kernel Panic problem.

Attached you can see what was displayed on the console at the time of the panic. This is what SoftLayer tech. support team was able to obtain from the console.

We are not using Samba or NFS-based applications.

How To Install Ffmpeg On Centos/rhel, The Simple Way
I seen where a lot of server management companies are charging big bucks for this, so this might save you some time and money.
First

Code:
nano -w /etc/yum.repos.d/dag.repo
Insert

Code:
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1
Then yum update and search for ffmpeg and install all ffmpeg packages including devel.
Seems there is some lib problems along the way so in /etc/ld.so.conf
add
/usr/local/lib
then
ldconfig -v
To install the php extension follow the simple directions on [url]
Then you should be all set!

Tried and tested on 2 different centos server, works fine.

Update A Red Hat (RHEL 4) Package (vsftpd)
With Red Hat Enterprise Linux 4 (RHEL 4), are updated packages made available, or are only security patches backported? Specifically I'm interested in vsftpd. Version 2.0.1 is included in the RHEL installation on a server I'm working on, but there is a bug fix in v2.0.4 that I'd like to get access to.

Is there an easy way for me to browse / search what packages are available for RHEL 4, preferably via website?

Bs Best Tutorial And Reference Guide For RHEL And GUI Admin
Is there a Windows GUI software for remote Admining servers that run on Red Hat Linux?

FYI: Currently I use Putty for remotely managing our servers.

So if you can recommend a GUI like Windows desktop software for remotely Admining servers running Red Hat Enterprise, I would very much appreciate that.

FYI: we have like 10 dedicated severs, so a desktop GUI that would allow one to monitor/manage multiple servers would be best. But if the GUI that you think is best can only remotely connect/manage one server at a time, requiring disconnecting to connect to the other server to Admin it, that is fine.

Also, I would love to hear what you think is the best book, best tutorial and reference guide for remotely Admining servers running RHEL? I am not looking for one of those books that are 1000 pages, but something that is a few 100 pages and can be read in 1 month assuming a few hours per day of reading.

RHEL 5 - 32bit V 64bit Running Cpanel 11 For Hosting
As cPanel is an integral part of server hosting and has the ability of compiling Apache 1.3.x with PHP4 (cgi) and PHP5 (dso) on your server OS.

Does anyone know or have baselines/benchmarks for which performs better generally for hosting: 32bit or 64bit RedHat 5 when cPanel 11 has compiled for the Apache and php mentioned above on either of these OS editions? (assume latest versions of apache/php4/5)

I was wondering if 32bit performed better or 64bit on a quad core Xeon. Don't forget PHP is compiled for prefork and not multi-threading for Apache 1.3.41 (which are considered legacy 32bit forked apps compiled against 64bit OS).

Or rephrased, could i be hampering performance by running it on a 64bit OS on a Xeon (X3210) or improving performance? I'd assume 64bit would offer better all round processing power, or is this a misconception.

I recently decided to get a server on RedHat Enterprise 5 X86_64 (64bit), when i wondered if 32bit version would have provided better performance and been the better options for compatibility.

Dell 1600SC DRAC3 No Keyboard Input With RHEL 5
I just got a Dell 1600SC dual xeon 2.8 from the Planet with a Dell DRAC3 remote access card. In my RHEL3 system this hardware combination works great, but in the new RedHat Enterprise Linux 5 system the DRAC accepts no keyboard input after RHEL5 loads, thus making it impossible to login to the OS through the drac remote console redirect. Tech support suggested it was because the RedHat Enterprise 5 and CentOS5 kernel does not load the PS/2 keyboard driver which is required for the Drac3 to accept keyboard input. (a drac4 works, but that's not an option for this server I would guess.)

At tech support's suggestion, I added
atkbd.set=2
to the /boot/grub/grub.conf file
rebooting had no change - still text input to enter the bios, but no text input to login to the OS.
I also added
serial --unit=0 --speed=9600 -word=8 --parity=no --stop=1
terminal --timeout=2 serial console
which I saw in /etc/grub.conf (which is not linked to /boot/grub/grub.conf but instead a separate file) but still no luck - no keyboard input accepted through the drac3 remote console to login to the os through the drac console redirect.

Has anyone solved this hardware/software combination? Or is RHEL5 simply not going to be backwards compatible with the Dell DRAC3 hardware?

Any ideas, suggestions, or solutions would be greatly appreciated as I've been working on getting a solution for this for a week now and no closer at this point.

I would really like to have the DRAC as a backup connection with my server incase any firewall or software update issue ever prevents me from connecting via ssh. I hate to have roll back to an older OS though to get it. I'm stuck.
