Improving Nicotine's Response

From: "andrew cooke" <andrew@...>

Date: Mon, 15 Jun 2009 21:23:36 -0400 (CLT) 

The following settings help Nictoine handle many incoming connections,
which sometimes happens with searches on popular terms:

sysctl -w net.ipv4.tcp_syncookies=0
ulimit -n 2048

The first leaves you more vulnerable to syn flooding attacks and the
second may require you to first raise values in /etc/security/limits but
addresses the warning "possible SYN flooding on port 2234. Sending
cookies." that can appear in the system log.
