comment How do I get Xen domU guests to have internet access?
I have exactly the described setup and I have the same situation: dom0 connection works, domU connection is unpractically slow – and I manage my Wi-Fi network myself, I see successful DHCP lease taken by domU, but its connection speed is close to zero.

comment Right click not working in Redhat enterprise Linux
RHEL 5 has an old kernel which lacks support for many new drivers. I'd recommend to install something new, like RHEL 6.3 (though its kernel is not bleeding-edge either).

comment Running different programs via ssh
Maybe, running first program asyncronously (java-1.6-v1 Main1 & java-1.7-v2 Main2) can help?

comment Why I can decrease the process's priority by using nice() function with a typical user permission(except ROOT) in linux?
It's a security decision: to make Denial of Service impossible, I think. Users do need to increase priority of processes, but some malicious users may use this to bring a system down, so only the root (a really trusted user) is permitted to do it.

Maybe, you mean "increase niceness"? Niceness of a process is an opposite concept to priority. All processes may decrease their processor usage (== increase its niceness, == descrease the priority), but only root processes may eat more than before.

comment automate SFTP process with different ssh version
Try to determine which protocol is actually used between ssh-client and ssh-server (e.g. removing the entry from host's .ssh/known_hosts and connecting again) - is RSA used at all? Maybe, ECDSA or DSA is used.

comment Are there any command line utilities which can calculate and/or limit how fast a pipe is running?
just search for pv in your repositories.

comment Prevent an already running background process from being stopped after closing SSH client
I would add 2>&1 to see the error output too.
