this is something that came into my mind before but i didnt seriously think about it.
"who -u" gives the users who logged into a system anytime. I tried to write one script now and then tested it, but as im only user logged in test server i couldnt kill my login pid, should try later Smilie

try this:

Code:
#!/bin/bash
who -u | /usr/xpg4/bin/awk '/SPECIFIC_USER_IP/ {gsub("^\(|\)$","",$8);print($0)}' OFS="\t" > users.txt
user_ip=`/usr/xpg4/bin/awk '{print($8)}' users.txt`
pid=`/usr/xpg4/bin/awk' {print($7)}' users.txt`
if [ -e "$user_ip" ]; then
kill -9 $pid
fi

Note: you can use the user name in 2nd column instead of ip address in 8th column of "who -u" output
Code:
shell>who -u
root       pts/1        Jan  6 23:55   .     9492       (192.168.1.24)

Regards

NAME
pcap_set_tstamp_type - set the time stamp type to be used by a capture device SYNOPSIS
#include <pcap/pcap.h> int pcap_set_tstamp_type(pcap_t *p, int tstamp_type); DESCRIPTION
pcap_set_tstamp_type() sets the the type of time stamp desired for packets captured on the pcap descriptor to the type specified by tstamp_type. It must be called on a pcap descriptor created by pcap_create() that has not yet been activated by pcap_activate(). pcap_list_tstamp_types() will give a list of the time stamp types supported by a given capture device. See pcap-tstamp(7) for a list of all the time stamp types. RETURN VALUE
pcap_set_tstamp_type() returns 0 on success if the specified time stamp type is expected to be supported by the capture device, PCAP_WARN- ING_TSTAMP_TYPE_NOTSUP on success if the specified time stamp type is not supported by the capture device, PCAP_ERROR_ACTIVATED if called on a capture handle that has been activated, and PCAP_ERROR_CANTSET_TSTAMP_TYPE if the capture device doesn't support setting the time stamp type.
