I setup a CentOS Linux based Linux server running as a gateway and firewall server. However, I’m getting the following messages in the /var/log/messages log file:
Dec 20 00:41:01 fw01 kernel: Neighbour table overflow.
Dec 20 00:41:01 fw01 last message repeated 20 times
OR
Dec 20 00:41:01 fw03 kernel: [ 8987.821184] Neighbour table overflow.
Dec 20 00:41:01 fw03 kernel: [ 8987.860465] printk: 100 messages suppressed.
Why does kernel throw “Neighbour table overflow” messages in syslog? How do I fix this problem under Debian / CentOS / RHEL / Fedora / Ubuntu Linux?

When I try to ping other UNIX / Linux / BSD or MS-Windows servers in our network I get the following message:
TTL Expired In Transit
How do I fix this problem?
I cannot install Apple iTunes software to manage music for my Apple iPod. How do I manage iPod under Ubuntu Linux? What’s the best way to manage my iPod without Apple iTunes software?
Q. I’m using Gnome under Ubuntu Linux and my numeric keypad is disabled. Pressing numlock key does not work any more. I’m not able to use numbers or special symbols from numeric keypad. Reboot does not help or using different keyboard does not help. However, numlock only works if I switch to text console by pressing CTRL+ALT+F1. Now, I’m dam sure this is related to X.org or Gnome. How do I fix this problem?
