knock on Scientific Linux 6.1? (perl script for knocking?)
I have an OpenWrt router where I mounted knockd:
knockd.conf [options] logfile = /var/log/knockd.log [openSSH] sequence = 7000,8000,9000 seq_timeout = 5 command = /usr/sbin/iptables -I INPUT -s %IP% -p tcp --dport 22 -j ACCEPT tcpflags = syn [closeSSH] sequence = 9000,8000,7000 seq_timeout = 5 command = /usr/sbin/iptables -D INPUT -s %IP% -p tcp --dport 22 -j ACCEPT tcpflags = syn
and also I'm having a note pad with Scientific Linux 6.1 where I intend to knock. yet appears there isn't any kind of "knock" plan for SL 6.1.
Where can I get the RPM for the knock binary? (Or exist any kind of choices for knock? A perl manuscript possibly?)
