<0> anyone here want to help me understand chillispot a little more than I currently do?
<1> RE
<2> RE
<3> hey guys im new to iptables and i need some help
<3> i use the following rules to forward a port to my machine
<3> the router is a slackware 10.2 running the default kernel
<4> rufiusblack - uname -a for kernal
<3> yeah its a 2.4.31 i believe
<3> hold
<3> yup 2.4.31
<3> $IPT -t nat -A PREROUTING -p udp -d $EXT_IP --dport 16104 -j DNAT --to-destination 192.168.1.4:16104
<3> $IPT -A FORWARD -p udp -d 192.168.1.4 --dport 16104 -j ACCEPT
<3> $IPT -t nat -A POSTROUTING -p udp -s 192.168.1.4 --sport 16104 -j SNAT --to-source $EXT_IP:16104
<3> this is what i do forward port 16104 to my machine
<3> i just wanted to know if i was doing it right
<5> iptables -I OUTPUT -p tcp --dport 25 -d smtp.bredband.net -j ACCEPT
<5> would that work?
<5> I have iptables -A OUTPUT -p tcp --dport 25 -j DROP
<5> but want to allow for only one smtp-host
<6> there is command which tests the open ports on a specified IP. which is it?
<7> remotely or locally ??
<7> :)
<6> remotely
<7> netcat / nmap
<7> :p
<7> well, nmap for exemple
<7> s/exemple/example/
<6> ok :)
<6> there are tones of optios
<6> i would like to test which ports are open on a specified ip
<6> what do I have to type
<6> ciel[busy]: please
<7> ui
<7> I'm reading
<7> By default, it tests a port range
<7> a wide port range
<7> but you can do :
<7> -p <port ranges>: Only scan specified ports Ex: -p22; -p1-65535; -p U:53,111,137,T:21-25,80,139,8080
<6> -p is ok
<7> you can use -p.
<6> but which is the optio for the ip
<6> i can't find the option for the ip
<7> there's is no flag
<7> SYNOPSIS nmap [Scan Type...] [Options] {target specification}
<6> got it
<6> :)
<6> thank you!
<7> it's okay
<8> istvank: ideally you want to read the man page, for a quick scan, as root, do: nmap -A -p1-65535 sitehere.com
<6> Strykar: what is the -A for?
<8> istvank: man nmap
<6> :)
<6> No manual entry for nmap
<6> :)
<6> -A: Enables OS detection and Version detection
<6> what is that good for?
<9> for attempting to detect what os the target system is running based on its tcp fingerprint (how it responds to certain types of requests) and what ports it has open
<9> wow i am responding to a post from over an hour ago how useless :)
