evms> I wrote this a while ago, but, if anyone is interested, please evms> take a look: this module implements a system call that takes evms> a u_int_32t. This system call, named killjail, kills all processes evms> which belong to the jail which uses that particular IP address. evms> I included it in a tar with a makefile and with a program evms> that uses it. (Eg: ./killjail 1.2.3.4) evms> http://www.sekt7.org/kjs.tar evms> Works on 4.4 but can be easily ported to 5.0. This can be done in userland without kernel interaction: #!/bin/sh EX_OK=0 EX_USAGE=64 if [ "$1" = "" ] then echo "Usage: $0 jailname" exit ${EX_USAGE} fi pids=`grep -l " $1\$" /proc/*/status | awk -F/ '{print $3}'` if [ "$pids" != "" ] then kill -15 $pids 2> /dev/null fi exit ${EX_OK} To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
