CentOS 5 Server :: Vncserver Freezes Some Sessions / Can't Click / Need To Restart Service
Nov 24, 2009
I'm running VNC Server on CentOS5 on a brand new installation, this is for some of my students to use specific software via VNC on their machines from home that they otherwise don't have access to on their Windows machines. This has been working fine on our previous server for a few years but the hardware is now outdated so I have upgraded and put a fresh install of CentOS 5 on. This works fine for about 24 hours and then eventually one of the session ends up freezing where the user then can see everything on their session, the cursor can move but they cant click a single thing.

I am setting up a server with Ubuntu Server edition. It is has 4gb of ram and had been working great the first week or so but something strange started happening about the same time I installed MythTV. After that, the server would slow down considerably and the ram being used would go from about 400megs up to all of the 4gb and use about 2gb or swap. After much research and investigating, I've narrowed it down to the vncserver starting up all 100 displays/sessions even if I try to specify one with : vncserver :1

How can I start the vncserver serivce before any uesr log in? because I only have one screen now what I already did is when I log in the vncserver service going to be startup, but I want it can start before I log in. I try the "chkconfig --level 345 vncserver on" but after I reboot, I still cannot access the system before I have a log in action.

I am using
# uname -rmi
2.6.18-194.26.1.el5PAE i686 i386
# cat /etc/*release*
cat: /etc/lsb-release.d: Is a directory
Red Hat Enterprise Linux Server release 5 (Tikanga)
CentOS release 5.5 (Final)
I have noticed that after few days of ideal system it will stop its network interface. To resolve this I have to login to the machine it self and then issue
# service network start
Is this a feature. If this is not a feature then what is this. As an workaround I am thinking of adding service network restart in cron tab for everyday in night when I am not using it.

I am new to Linux and I am trying to set up a mail server using postfix. I have done all the configurations(hopefully correct) and all the test seems to work except 2 things.
1) Postfix is running but when I try to restart the service it always fails. I checked the /var/log folder and there are no error messages.
2) When I try sending e-mails using outlook, outlook fails to connect to my server.
I am wondering if I have done the configurations properly. I am a little confused in regards to hostname and domain name. When I do a hostname on the terminal I see the hostname that I gave my server. When I do the domainname command however, domain is none. Is it necessary to have a domain to configure postfix? I have myhostname = my.hostname.com what should my domainname = to if there is none. If I do require a domain name how to I create one? I need to be able to access e-mail from external clients.

I have a suspend problem in my laptop. Sometimes, when resuming from suspend, the network adapter is down (that is, the network does not work and the light of the network adapter is off). Restarting the network service doesn't work, because I think that the system forgot about the hardware, and probably the driver should be reloaded.Does anyone knows how to do that?(ps. /etc/init.d/networking restart does not work, because the hardware driver is not being recognized anymore).

whats the difference between restarting/stopping apache using 'service httpd restart/stop' and apachectl restart/stop. I know that using 'service httpd restart' is actually a script in /etc/init.d/httpd but what about apachectl?

I have a webservice which runs under Apache Tomcat. The service is started via a script in /etc/init.d. During the course of the Web service processing, the software must make use of the two NVIDIA GPUs on the computer to do some graphics processing. When this system is booted but not logged in, the web service is accessible but the software cannot access the software cannot access the X server to do it's processing. However, when I am logged in, the user can access the X servers and run correctly. I have tried various solutions but I always have to be logged in to run the software. I seem to have permissions problems but I'm unsure how to resolve them
Is there any way to grant permissions to root (the tomcat service is started as root) to allow it to run the software without logging in?
I am running CentOS 5.4 with Gnome display manager.

I am trying to accomplish an objective, I need to get 389 Directory server installed in the process however is it possible to just have email addresses of users in the LDAP server? I have a primary domain, example 'abcefg.com' with about 3,000 users and several hosted domains like 'xyz.com' and 'mno.com'. The end goal is to speed up email processing, so instead of the Barracuda asking the email server(s) if a user exist it queries the LDAP.
Is there a way to configure 389 Directory Server to contain just the email addresses of the end users to allow the Barracuda to poll the LDAP server to verify the email address is valid. The rest of the authentication like password is handled by the email server. So in the end the LDAP server would just contain the email addresses (live) and the Barracuda would query the LDAP asking if joebob@abcefg.com exist if it does carry on. If user xxeedd@abcefg.com does not exist drop it and go on.

I have a service I've made an init script for, and it's added to chkconfig, which shows it "on" in all the correct runlevels. When I start or stop this service using the "service" command all is fine, but it does not start on it's own at bootup. I am currently at a loss to determine why it is not starting. Here is the script:
#!/bin/bash
# chkconfig: 2345 95 10
# description: Start or stop home automation

I have just finished bulding a virtual web hosting server on my CentOS-5.5 x86_64 linux box with several websites hosted and its working fine. Now I have to build and FTP service in this webhosting server so that i can create indviudal login for each website and provide access to thier respective web directory only. This is where I am stuck. I have been trying to find out some docs and instructions to achieve this but in vain.
What I need is to configure an FTP service in the web server so that individual owner of websites can login to thieir respective web directories only and upload and download files as well as create, delete and modify the contents of their web directory.

I am new to linux, running a brand new centos 5.2 server. One application I want to use it for is to serve as a network host for a game my friends and I enjoy. Normally, to run the game in host mode you call the binary and pass it a port number (along with other options). To host a second instance of the game, same thing different port, you get the idea.
After doing that the binary runs in your window and dumps to stdout, so if you want it to run 24/7 you have to come up with your own strategy like nohup. Fair enough, now, I'm trying to coax the game into restarting automatically upon reboot. The most correct way to do this seemed to be to write a script for init.d so that's the road I traveled down. Now, to strain the metaphor, the pavement has ended and I'm stuck in the sand.
Here begin my questions:
I've been following the structure of other init.d scripts and I notice they all seem to call the function daemon() (contained in /etc/init.d/functions) to start their services. Looking at the structure of daemon() I see that you can pass it a user and a pidfile. The user part seems to work fine, but no pidfile is created. Let me be more specific.
Like the other scripts, I explicitly touch /var/lock/subsys/game-port on startup, which works fine. However, all of those other services seem to have a pidfile in /var/run and mine doesn't. They don't create it explicitly in their init.d script therefore I assume that some other process is creating the pidfile. At first I thought it would be the call to daemon(), since you have the option of passing it --pidfile, but that doesn't seem to work.
Are the services themselves creating the pidfile? If that's the case then I have more complications because the game binary apparently doesn't do this. Second question but probably related to the first. None of the other init.d scripts I looked at seem to do anything special to detach their services from a particular terminal session, therefore I didn't think that I would need to either.
Again I thought this was something the call to daemon() might accomplish, but either I'm wrong or I'm doing something wrong. I can probably work around this with nohup or appending '&' or something, but I'm just curious that other services like crond, sshd, named, etc., don't seem to do this. Are they determining this behavior from within the binaries themselves? I hope this is clear, as I said I'm new so I may not be getting all of the terminology correct.
