I've a java program which needs to be executed regardless of whether a user is logged in or not. Currently I've a shell script which executes the java program. I login to the server and run this shell script when the server is rebooted. I would like to start this script automatically preferably as a service so that I can stop and restart this service whenever I update the java program.
View 3 RepliesThere is a particular java app called LanguageTool which we need to host on our centos server. Other applications are supposed to send an http request to this machine; this machine should pass this data (received over the http request) to the java application concerned, obtain the output from the app; and then send this response back to the requesting client...
We need to set this app as a service on startup. The centos machine might restarted from time to time; so we expect this service should startup automatically. What can I do to get this done?

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?

View 3 Replies View RelatedI 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.

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.

I have installed CentOS 5.5 on a computational cluster and want to limit the disk space used per user to 10GB. I do not know what is the relation between blocks and the the volume i want (10GB). What is the values I should used in the file opend by "edquota username" command? What is the usage of inode? there are soft and hard items in columns 3 ,4 and 6,7. Which of them should be configured? here is the example by CentOS documents. I only changed the file system which is in my case /dev/sdb0 (this is mounted as /home in my system. What changes I should do to this example to limit the user to 10GB disk scape?
Disk quotas for user testuser (uid 501):
Filesystem blocks soft hard inodes soft hard
/dev/sdb0 440436 0 0 37418 0 0
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.

View 2 Replies View RelatedI am working on the beginning of implementing a two-node cluster with shared storage (GFS) and IP address. Both machines are virtual on VMware ESX 3.5, that should not make a difference, but that is the background.current status is that I have a single node cluster built with only the IP address configured within the cluster. The issue that I am having is that I have configured a service to contain only the IP address resource, however, when I go into cluster management that "service" does not register. As such, I cannot bring it online, ping it, etc. below is my cluster.conf configuration:

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.

Myself and a friend have our own small IT business; we mainly design and build web sites for other small businesses. One of the things we would like to offer to clients is the ability to relay email addressed to their company's domain to their own personal email address (either web-based, or hosted by their ISP).
Now, clearly there is a risk of our mail relay being marked as "open", and therefore becoming black listed as a source of spam. Not something that we want to happen!setting up such a system? I understand how I would go about configuring an MTA like Postfix or Sendmail to perform such a task, but I'm unsure how I would ensure that relayed mail is delivered and we're not labeled as spammers.
I did wonder if perhaps the "mail forwarding" options in a mail server like Zimbra would get around the issue by forwarding on messages inline or as attachments within new emails (so the messages would appear to be from the account hosted on our server).
