comment how do I disable autonegotation and force specific ethernet settings?
@vezult a successful negotiation depends on the capabilities of both ends. And I am not referring only if 10/FD is supported but if they can negotiate to 10/FD. So it depends on the firmware and drivers of the NIC or switch on endpoints of the link, especially if you have old hardware.

Those are file system caches, not CPU caches.

You need to run as root or as the same user as the process.

Try the same command with sudo as a workaround.

I think it is a bug in su. See this bug report: bugs.debian.org/cgi-bin/bugreport.cgi?bug=663200

comment do i need IPTABLES to enable IP FORWARDING?
Usually, private address spaces are not used for routing. If he needs routing, plus the fact that he is new on this site, and if he is using private address prefixes...

comment SSL/TLS Client certificate Authentication using RewriteCond and Rewrite Rules to perceptively redirect traffic not authorized
The client can not send the certificate after the SSL session is started. It must be a SSL renegotiation to add the client certificate later in the SSL conversation. If you do not see this renegotiation, that means that either the server did not ask for a renegotiation. The renegotiation can fail if the client doesn't provide a client certificate, because it does not have one. A valid "client certificate" is actually a PCKS12 keystore with a client certificate and a private key.

comment Move a WMWare Workstation from an Intel 32-bits to a AMD 64-bits with two proccesors
If the VM is running fine, then the VM transfer is ok. It is very important that the guest kernel is fully supporting the new cpu. Reinstall VMware Tools on the guest that was moved.

comment Move a WMWare Workstation from an Intel 32-bits to a AMD 64-bits with two proccesors
The snapshots taken when the VM is shouted down are fine. Only those taken when the VM was running are not portable. Usually, you can only move 32bit VM from and to a 32bit host. 64bit VM are incompatible with 32bit hosts. Even if they might run, they will run in emulation mode at much slower speed.

Did you changed the firewall rules or /etc/hosts.* in the last few days?

if you run dmesg do you have any messages containing oom-killer? If you have, then you are running out of physical memory.

Try to use strace as @Zoredache said. Complementary, you can use pstack and ltrace too.

comment Client can not access some HTTPS through Squeeze gateway
When it is not working, did you check if there is any error in the proxy log? You can also use Fiddler2 with the browser to analyze the traffic. You can also use Wireshark to find our if there is a SSL negotiation error (look for ALERT messages in the trace).
