I am developing a some application which running on rhel4 os. And its functions will handle via the web application. So we have provided an option to login (via vnc)to the server on web application when we need. so how we can enable vnc for a session (like 30 minit)? I'm using default vnc installation while installing rhel 4 nothing more installed by downloading. When I click session button on web page, I execute this command from my code
"service vncserver start"
then I can access server via vnc but when I click on disable button on web page, I execute this command from my code
I noticed (the hard way) that enabling a guest session under 9.04 does not lock the source user. I enabled a guest session for someone and came back to find them rooting through my files. By quitting the guest session, it goes back to the source user's desktop without requiring a password. Shouldnt it go to gnome-screensaver automatically? Can this be changed? Is it a bug?
to replicate: log into source user's account use the menu to start a guest session quit the guest session root through files un-opposed.

We have done an installation on a blade server (HP) for RHEL4.5.
The server have an HP smart array 2200 controller and during installation it can see the controller and disks just fine.
The installation completes up to the point where the system needs to reboot , however after the reboot it does not start up again and get stuck at the message: "Trying to boot from drive c:"
We used the rescue option to mount the installation and cant find nythign wrong, even with the grub setup (except that it points to hd96 as its primary disk). we tried changing this to hd0 as well but still no luck.
After about 3 installations we are still not having any luck.

I've been trying to track this kernel panic down for the last few days on this system... I believe it might be autofs/nfs related, but I'm not 100% sure.

I need to implement a form of filtering. Current topology is like so:
Internet -> Smoothwall -> MS Exchange server (w/ OWA) -> Clients
So I need to enable transparent spam filtering on the smoothwall system, which is a full fledged Linux system. There are no 'free' modules available for smoothwall that enable spam filtering. And due to the monetary constraints of the project I'm working on, something free is required.
I don't have any experience with this - I've done a couple of searches and came up with "SpamAssasin", but I can't find any relevant guides that allow transparent scanning - they all assume the mail is stored on THAT server.
So I'm here to ask the more experienced people what sort of packages will enable this functionality? Would like something that has a WebUI, but that's not absolutely necessary.
We have been using an Ultrium LTO-2 tape drive to perform backups of certain information from our file server. Recently, the data that we are backing up has grown too large to fit on the tapes in their 200GB uncompressed capacity. I have been looking around for a way to enable the compression in the drive, but I haven't found much. I am not using any backup software, so I'm not sure if I'll even be able to. I write the tape using a simple 'tar' command, so there aren't a whole lot of options to be set. Is there a way that I can enable the drive's compression, or would I be better off running the tar command with the gzip or bzip flags?
I didn't know if I should have posted this in newbie, hardware, or server. I haven't used tape drives in Linux previously; however I'm trying to figure out how to enable an LTO-4 tape drives built in encryption. Im not that concerned with secure key management, I am looking to just being able to load a key into the drive and get the tape to encrypt. Im for a simple command, but I dont even know where to start. If it varies by device, its an HP Ultrium 4 (1760).
Migrated bunch of RHEL4 servers from one enclosure to another. Could not connect to SAN as adapter state was showing "DEAD". These are Proliant BL460 and BL680 Blades with native RHEL QLA2300 and QLA2XXX drivers. It only happended to RHEL4 servers and no issue found with RHEL5.x servers.
I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.
All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.
Is there a session manager I can use with 10.10? I would like to try Openbox but am not sure how to select it as a startup session. I would like to be able to choose between kde, gnome and openbox.

i have created a wordpress user with a symbolic link from his home (/home/wordpress) to /usr/share/wordpress but when wordpress ftps to wordpress home dir it does not follow the sym-link. is there a way to set default ftp dir for the wordpress user to /usr/share/wordpress rather than /home/wordpress?
Attempting to run k3b as root returns this: localhost mark # k3b unnamed app(3518):
KUniqueApplication: Cannot find the D-Bus session server: "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."
unnamed app(3517): KUniqueApplication: Pipe closed unexpectedly. I am using the IDE-CD drivers. I have /dev/hda and /dev/hdb (cd and dvd rw's). This was working fine recently before my last emerge -u world.

Changing permission and groups of the devices accomplishes nothing.
I am putting together some new systems for my customer and I'm having some trouble with a script that we use to back up files to a DVD R. The problem is that I can't write a 2nd session to the DVD unless I eject the disk and reload it. The drives are slimline type drives, Sony BD-5730S and Teac DV-W28S-V93, so they won't reload without human intervention. Opsys is CentOS 5.4 or RHEL 5.4. I've tried both AMD and Intel based mother boards. If i try this on Fedora 11 or 12 it works fine. This works on IDE attached drives but not a SATA attached drives. Fedora appears to use something called genisoimage instead of mkisofs. I can't get genisoimage to run on CentOS or RHEL.
Here's the code to setup the test files:
rm -f /tmp/BDtest/* mkdir /tmp/BDtest dd if=/dev/zero of=/tmp/BDtest/blank.iso bs=10M count=1 for NUM in {1..160}
When I am running linux on my laptop, my ssh session to a particular server keeps getting randomly dropped. What should I do to troubleshoot the problem?
To connect server use mstsc.exe in windows, rdesktop in linux - if you do not have it yum install rdesktop. But if you use different from english localasation of fedora, you will see only english Gnome and instead of your local fonts in terminal
[code]...
Now you can use fedora RDP session with your native language.
I have been using proftp for about 8 months. After getting the configuration right, it worked perfectly. It is only used intermittently, so I don't know for sure when the problems started, but I suspect it was triggered by a recent OS upgrade to Ubuntu 10.04 (64 bit). I have proftp set up so that TLS is required on both the data and control channels. The problem is that, after successful login, the server seems to be terminating the session because the client (FileZilla) is attempting to renegotiate something (probably the TLS). The client settings didn't change, nor did the server settings.
I have tried switching off the TLSRequired flag, and am then able to establish a non-secure FTP session which works (but that does not meet my requirements). I wondered whether the OS upgrade had somehow invalidated my TLS certificates, but the symptoms don't seem consistent with that cause. The TLS part of my proftpd.conf file is:
