CentOS 5 :: Writing 2nd Session Of Multi-session DVD?
Jan 22, 2010
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}
I just completely put Ubuntu on my laptop and I am looking for a replacement MSN messenger that allows multi-session. Basically, in most of the WLM versions of MSN Messenger it allows Multi-session, as in I can login into the same MSN account on both my desktop (Windows) and my laptop (Ubuntu). Both Pidgin and Empathy don't, and rather going through all of them I thought I'd ask here.
Is there any way to save data to a DVD & leave the disk "open" to add files after the session is closed? I like to backup my MP3 files to DVD's, been doing it for years using Windows Vista. As I collect more MP3's I add em to the same DVD. Can't do this using Brasero or any other program I have tried - once I write a file the disk is closed.
I'm creating a new thread based on this post by batagy:

So I have running x11vnc as service without any problem (running on Solaris 10 and SLES10 too). I'm using the x11vnc's inbuilt "user chooser" screen (that little black screen), these command line options:
x11vnc -inetd -unixpw -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY-Xvnc.xdmcp -env X11VNC_CREATE_GEOM=1248x900 (plus a couple of other options that are not interesting here)
My question is related to the wanted VNC screen size. By default, I set the defauls screen size to 1248x900, as can be seen above.
Currently , when a user want to personalize his/her screen size to be started, he can do it this way: when the small black authentication window is appearing first, after his username, he's entering a colon, then specify the wanted resolution in this format: geom=1600x1200.
My question: is it possible somehow to set automatically the preferred screen size, without entering this ":geom=1600x1200" string in the authentication window? I mean to set it per user, without modifying the service options. I mean, for example setting the X11VNC_CREATE_GEOM or FD_GEOM variables in the user's home ".profile" for example?
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 am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).
Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.
I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.
The following message comes up when I boot up: Logging in user Warning: Cannot open ConsoleKit session: Unable to open session: Launch helper exited with unknown return code 0. When I press OK, the system completes the start up and everything looks normal. But when I try to connect to internet, I get the following message:
KNetworkManager cannot start because the installation is misconfigured. System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution. KNetworkManager will not start automatically in future. If I reboot the system, I logg in successfully. So far the problem has appeared approximately upon every second time I boot up. Rebooting the system seems to take care of it.
Don't know what info is of interest. I'm using
Opensuse 11.2 KDE 4.4.2 (Factory) After upgrade from 4.4.1 to 4.4.2 it worked fine for a week or so.
I do a clean install of slackware64 13.1 beta1 with KDE and switch default runlevel to 4 in /etc/inittab.
I try to login in kdm, I always come back to the login....
I try this with default runlevel 3 and an .xinitrc with "ck-launch-session startkde" .. works without problems, so I switch back to default runlevel 4, now i can login and only get the error "Cannot open ConsoleKit session: Unable to open session..."
I have to run a graphical session for using something with wine on a server (unfortunately :((( ) and I'd like to run a TWM session. As I would like to lock the session, I settled things to log on from XDM. However, I can't find anyway to lock the session. Is it possible (I guess yes) ? How can it be achieved?
My server (CentOS 5.5) is a ldap client authenticate to LDAP server (Successfully authenticate) I use pam for ssh. I can ssh successfully with any users on system. But I cannot su - from ssh. It display the error: Could not open session. I look to log file and it shows: # tail -f /var/log/secure
On my machine, I am not able to login using any of the user account or root. It's showing this message:
Then comes another message: YOur session lasted for less than 10 seconds. Try logging using Failsfe. .... session_child_run: Could not exec /etc/X11/xinit/Xsession default
I tried to use the failsafe as well, but nothing seems to work.
Would someone please help me regarding this issue?
Session management with gnome-session-properties and GDM appears to be broken in CentOS 5.3 and 5.2. I can't comment on earlier versions.Activating "Automatically save changes to session" does work--for example, on the next login, the terminals that were open at the last logout are reopened.
But if "Automatically save changes to session" is not selected, according to help,"when you end your session the Logout Confirmation dialog displays a Save current setup option."This does not happen. No "Save current setup" is offered, regardless of whether or not "Ask on logout" is selected.
Also according to help, if one has added sessions with gnome-session-properties, then when one logs in "on GDM, you choose a session. When you choose a session, you can select which of the multiple sessions to use."This does not happen. No matter how many sessions one may have added with gnome-session-properties, none of them appears in the list of sessions that GDM presents.
So it appears that only a small fraction of session management functionality works in CentOS 5.3 and 5.2.
I have 2 servers, I set the first one up so that I can remote to it and connect with VNC over ssh by following:[URL]ServerThe 2nd server I did the same, but I cannot connect! When I do, vncviewer prompts for a password and then opens a window of the correct size, but it is all white and then my ssh session is locked! I can't enter any more commands, I have to kill the session.
I have centos 5.5 like a OS in my computer, and i wana add a arabic language in the frensh session, i mean i wana list the arabic site in the frensh session.
I am running matlab 2010b on centOS5.6. Matlab opened without any error either in the computer terminal or in VNCSERVER. While running bench (of matlab) the session or the vncserver are crashing.In some cases the bench run for the first time without any problems, however it will crash the session or the vncserver on the 2-3 runs of the same code.
I am using CentOS 5.4. I created a bash script that does some checking before running any commands. If the check fails, it will simply exit 0. The problem I am having is that on our server, the script will exit the su or ssh session when the exit 0 is called.
#!/bin/bash # check if directory has contents and exit if none if [ -z "`ls /ebs_raid/import/*.txt 2>/dev/null`" ]; then echo "ok" exit 0 fi
Here is the output: [root@ip-10-251-86-31 ebs_raid]# . test.sh ok [russ@ip-10-251-86-31 ebs_raid]$
I was removed from my sudo session, if I wasn't in the sudo session, it would have logged me out of my ssh session. I am not sure what I am doing wrong here or where to start.
I installed squid 2.7 and want to use squid_session external acl rule. But there is no squid_session in any dir, looked everywhere. On my Ubuntu box I also have squid 2.7 and there I have squid_session.
I have been updating my system and making a few changes and now I have a serious problem with GNOME (as far a I understand). In the Desktop if I try to start some applications such as the text editor gedit it crashes and won't start. Some applictions start from the menu some don't (e.g. services) and others start and then crash if I try to example manipulate them (e.g. open a file in openoffice).
In the case of gedit if I try to run it from the command line as root I get the following
# gedit
(gedit:6475): GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed.Illegal instruction [code]....
When I try to start the services (i.e. /usr/bin/system-config-services) I get:
I want to run X window graphical application over ssh session on my server running Centos 5.5 . i used the -X flag for ssh (ssh -X user@serverip). i checked the /etc/ssh/sshd_config file on the server and i have the line "X11Forwarding yes". but i can not run any X applicaton. when i use root account i get the message: xauth: creating new authority file /root/.serverauth.15813
I have installed VirtualBox as per the instructions on this site, and the kernel module compiled without problem, however when I start it, it causes the user to logout!
I am using the nvidia module from the ATrpms repo if that has any bearing on the problem.
Has anyone else seen this issue?

I would love to auto-start tomboy at startup. How can I do this ? [Moderator edit: fixed Subject so nobody would expect an automatic Lunch. Is that the same as a free one? ]
what program runs the Session lock and the screen saver for gnome and KDE on centos 5.5. But most importantly id like to know what the config file for the screensaver/session lock is called and where its most likely located.
