I have a situation where I want to install various versions of RHEL on removable drive. My first option was a flash drive or an external USB hard disk, but its speed is too slow.Now I have been assigned a task to search for more options about this requirement. If anybody has experience in installing the same, then please share with me.
View 6 Replieswe are using a DELL server installed with RHEL release 3(update 2) for running SS7 stack. we are using it for telecommunication testing. from last two months it is getting out of network though the server is up. we are not able to connect it through ssh using putty from local desktop. I tried searching for the reason in logs under /var/log/messages but i could not fine it. please tell me the path under which i can find the system error messages.

View 2 Replies View RelatedI 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.

I have two problems. I installed a RHEL variant (scientific linux) on an already dual boot system with ubuntu and vista.
It replaced GRUB with (I think an older) GRUB version and to add to that I cannot see my ubuntu ditro anymore. is there a way of reinstalling the GRUB that came with ubuntu then adding the RHEL distro to it?
my second problem is that I cannot figure out how to enable wake on lan in scientific linux (RHEL). on ubuntu I would just write a small script and update all runlevels to run it at startup. what is the alternative on redhat?

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 mail.domain.com.au.
I've edited the '/etc/mail/sendmail.mc' and added the :
Code:
line to it.
Also added the domain (domain.com.au) to the '/etc/mail/local-host-names' files
Also edited submit.mc and added
Code:
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:
Code:
So it seems to be sent to the queue no problems and when I check the queue :
Code:
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.
In oreder to run an application software on RHEL 3 ES server, I created a link forcefully using following command from root id:
# cd /lib64/tls/
# ln -sf libc-2.3.4.so libc.so.6
before that I copied file libc-2.3.4.so from a workstation with OS RHEL 4 WS so that a link can be created.
Now I am unable to run any command except cd & pwd and it gives error messaage as given below:
ls:relocation error:/lib64/tls/libc.so.6:symbol _rtld_global_ro,version GLIBC_PRIVATE not defined in file ld-linux-x86-64.so.2with link time reference.
Before running this command libc.so.6 was pointing to libc-2.3.so file in path /lib64/libc-2.3.2.so.
I am now unable even to open a new window on the server.Please send me some solution as early as possible because this server is running production data and many users are runnig application on this server.
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?
I have a RHEL 5 server with 32 bit architechture that is not recognizing more that 4 GB of RAM and I am trying to locate a version of the kernel-PAE package that will work well with the 2.6.18-53 kernel. I found something on Open VZ called ovzkernel-PAE that is built for the 2.6.18-53 kernel [URL]
and wanted to find out if there were any known issues with this release before I attempted to install it. Is anyone aware of any issues with any rpms on openvz.org or with this particular rpm in general?
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.
View 5 Replies View RelatedI am trying to look at installing the PAE module on a RHEL 5 2.6.18-53 system and I cannot seem to find that around. 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?
View 4 Replies View RelatedI 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?

View 7 Replies View RelatedMy 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.
