Red Hat :: VNC With RHEL 5.2 Server

Aug 5, 2009

I have seen and tried a lot of web information about issues with VNC and the RHEL 5.x implementation of VNC.

I can't seem to get the behavior I want. Let me explain.

With SLES 10, I can use YaST and with a few clicks end up with a system that when rebooted, accepts VNC viewer connections to :1 and displays the system login screen.

Here I can log in as root or any user. Once logged in, I can choose to use the command line to restart the system if necessary and eventually, I can reconnect with the vncviewer to the system login screen.

RHEL 5.2 has a "share your desktop" setting in preferences which works fine, but requires that I be logged in locally, which prevents remote restarts. There is also a system services dialog that refuses to start vncserver as a service. There are numerous tutorial in the RH knowledge base and the web that explain how to specifically setup individual displays, :1, :2 for specific users and claim that it can work after boot. I have not been able to get these working, but what I really want is a simpler, single display, :1, that will present the RHEL login screen so I can log in as any user I want. I am the only person accessing these servers and they are behind a firewall using secure protocols when remote.

I think Red Hat did not want to make this too easy as VNC users need to consider the security risks. Is there a way to get the SLES 10 VNC approach to work on RHEL 5?

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 :: Setting Up Sendmail On A Blank RHEL 5.5 Server Setup

Jun 21, 2010

Having some issues setting up sendmail on a (basically) blank RHEL 5.5 server setup. My ultimate goal is to be able to automagically send logs / errors / notifications to ourselves from the server.

Our basic setup is a Win 2003 domain with exchange running on

I've edited the '/etc/mail/' and added the :


line to it.

Also added the domain ( to the '/etc/mail/local-host-names' files

Also edited and added


When I try and send a mail from root or a test user to one of the domain accounts, it seems to go fine, i.e no errors are reported but it never gets delivered.

From the mail logs:


So it seems to be sent to the queue no problems and when I check the queue :


Total requests: 0

Not nothing ever gets received. Am I missing something? I have read and read and read but dont seem to be getting any furthur.

So in the end this server doesn't need to do anything except be able to send mail from root to an external mail address.

Server :: Windows 7 Can't Write To RHEL 3 Server When Files Greater Then 1kb?

Mar 12, 2010

we are running a Red Hat Enterprise Linux ES release 3 (Taroon Upd 5) Kernel 2.4.21-32.ELsmp since several years. The server hosts an old ERP system who will be replaced at the end of the year.However it is necessary that some collegues are able to write some files to that server regulary. Since we are running Windows 7 on several machines, those users aren't anymore able to write to the samba share. Getting files from the share works fine.

But the problem seems not to be situated at the samba service because also the transfer using SSH (WINSCP) from any Win7 system to the server doesn't work.During testing we recogniced that transfering files smaller then 1kb works fine ... any file greater then 1kb ends up in an connection abort. This works with samba and also using SSH.All the workarounds editing some registry entries in Win7 for improving the interoperability between vista / win7 and samba don't work for us ... and also seem not to be the source of the problem.Is there a general known incompatibility between our RHEL version / kernel and Windows 7 regarding file transfers?

Server :: Use Already Configured RHEL Server To Kick Other Servers

I have a RedHat box that I have configured, security, audit rules, latest updates, etc. I want to be able to "image" that configuration so I can kick other boxes with that "image", that way no other configuration/updating needs to be done on the newly kicked boxes. What is the best way to accomplish this? To make things more difficult, it would be near to impossible for me to pull any software off the internet for this.

I had hoped to find out if installing the CentOS 5 2.6.18-128 or 2.6.18-164 kernel-PAE modules would have a lot of negative consequences? Perhaps one of you could direct me to a download site that would provide kernel-PAE for a 2.6.18-53 build?

Server :: Ssh And Kerberos In RHEL?

Aug 3, 2010

I've my RHEL4u4 integrated with Active Directory.

I can logon to computer with username/passwd from AD.

But if I try to use ssh, is doesn't work

When I try to connect to the same computer using kerberos I receive this messages:

ssh -vv
debug1: Authentications that can continue: publickey,gssapi-with-mic,password
debug1: Next authentication method: gssapi-with-mic
debug2: we sent a gssapi-with-mic packet, wait for reply


and it tries to use publickey and finally, user/pass.

What do I've have do for using ssh and kerberos? I use samba for joining computer to AD. I tried it in ubuntu 8.04 and likewise-open and it works, but not in RH-Samba.

Networking :: Clustering RHEL 5.2 Server?

Mar 2, 2010

My current project environment setup is having a single server, running on RHEL 5.2, that is constantly receiving incoming data (video and text) over a periodic interval e.g. every 30 minutes. Initial in-house testing projected the server will be generally busy, so we decided to incorporate a second server for load balancing purposes. So now, server A and B will need to be clustered. Once that is done, incoming data will balance out between the two server (or at least that is what I will like to achieve. Note, I'm aware that at the switch side, I'll need to do some additional configuration and that part is covered).

I've been reading on Red Hat Cluster Suite and the Linux Virtual Server (LVS) seems the way to go. However, I noted that the LVS solution require at least a two-tier solution, and that would incur 3 additional servers instead of just 1. So here's my questions:- I looked around and probably know the answer, but I'm gonna ask anyway. Is there a one-tier solution for LVS i.e. have anyone tried or whether it's even feasible. From my reading, it don't seem so but just want another opinion. Is there any other way for me to do the clustering (for load-balancing) without LVS?

Sidenote: I'm currently looking at Ultra Monkey and will be trying out in a while. However, the project I'm doing would be rolled out to live site eventually, and my customer is kind of....particular. I'm just wondering if there's a software/application (that need to be purchased) and comes with support.

Server :: Enable/disable PAE In RHEL 6?

Jan 12, 2011

Anyway, according to the release notes, RHEL 6 has a PAE enabled kernel by default. Great... But that leaves me wondering why uname report SMP. Further, I'm provisioning some systems for QA use, and they're asking that PAE is disabled. My thinking is that since RHEL 6 requires PAE capability to install, there may be no way to disable it and the googling I've done seems to support this. tl;dr Why does a default kernel with PAE enabled report SMP on RHEL 6?

Server :: Font Configuration In RHEL 5.4?

Feb 25, 2010

I have few doubts regarding fonts configuration in RHEL 5.4.

[vinay@linuxcoe4 fonts]$ cd /usr/share/X11/fonts
[vinay@linuxcoe4 fonts]$ ls
100dpi 75dpi encodings misc TTF Type1 util
[vinay@linuxcoe4 fonts]$ cd /usr/share/fonts/


What is the difference between fonts in /usr/share/X11/fonts and /usr/share/fonts

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 ?
