Like TrevorH said the RSS of the JVM process is not going to be the size of the heap because the heap is just the amount of memory available for Java objects. Also the JVM might not return the memory to the system (which the GC reclaimed) if it sees the application keeps requesting memory for new ob...

Thats kinda weird since as you state yourself RSSOwl uses SWT which is just a (thin) Java layer around GTK. I'm running Eclipse on CentOS 6.3 and my font rendering is the same as on Fedora 17. Since RSSOwl is also based on the Eclipse platform that makes it even weirder. Maybe RSSOwl uses an older S...

The program which (by default) displays the GUI login is called GDM (Gnome Display Manager). Knowing what it is called should make your search easier :-) . You can find various instructions on the net how to do it. Here for example: http://www.cyberciti.biz/tips/howto-unix-linux-change-gnome-login-b...

What are you trying to accomplish ? FreeNX doesn't do any authentication by itself by default; Thats all done by PAM (unless you disabled PAM support).

EDIT: Just realized something...

The StrongSwan testcases provide hundreds of ready to use examples: [url=http://www.strongswan.org/uml-testresults.html]strongSwan UML Tests[/url]. Just click on the type of setup you want an example of. For example ikev2 -> rw-cert to get all configuration files for an IKEv2 Roadwarrior setup which...

Making snapshots and backups with LVM is described [url=http://tldp.org/HOWTO/LVM-HOWTO/snapshots_backup.html]here[/url]. Backuping VM's by LVM snapshots is a good option. Altough it depends on what is running inside those VM's. Backuping DB's via snapshot is probably a bad idea (unless you use some...

Well you could make a snapshot with LVM and make a copy of that. Just make sure that stuff like /proc /sys /tmp and /var/tmp aren't backupped. However I would advise against copying everything for the following reasons: 1. Databases (PostgreSQL / MySQL) etc. will probably have to be shut down (or in...

Have you checked the SELinux log file "/var/log/audit/audit.log" to determine if and why SELinux blocks access to that file ?

If you remove all the relevant information out of your post its going to be hard for us to help you :-) Please provide the (unredacted) output of "route -n", "arp -n", "brctl show" and "ifconfig". If those only contain private IP addresses (172.16, 192.168, etc.) there is not much point in obscuring...

[quote] I want to reroute certain IP's to a different server. [/quote] Do you really mean entire IP's or do you mean specific ports of certain IP's ? If you want to "hijack" a couple of ports from certain IP's then you could forward them. However I would advise doing this on a central firewall / rou...
