Prevent disconnections on SSH client

Posted on January 31, 2016 - September 18, 2016 by Mr. Reboot

To prevent disconnections on client side in your SSH terminal you can add this parameter to the configuration file /etc/ssh/ssh_config:

ServerAliveInterval 100

Basically this option will send a null packet to the remote host every 100 seconds and will keep alive the connection.

Fragment table on cisco 8xx

Posted on January 31, 2016 - September 18, 2016 by Mr. Reboot

If you get this message on logs:

VFR-4-FRAG_TABLE_OVERFLOW: Dialer0: the fragment table has reached its maximum threshold 16

usually indicates than you are receiving a high number of fragmented packets. It may happens using p2p applications like torrent or emule, under an fragmentation packet attack or another causes.

You can increase this value and check if warnings disappear:

router(config-if)#ip virtual-reassembly max-reassemblies 64
