<0> thanks
<1> Hello.. this is not directly iptables question, but I think some of you may know the answer better. I need to do a localport forward from machineA to machineD going though B and C .... machA <-> B <-> C <-> machD I know how to do from A to C ( -L localp:machC:port machB) but I have an extra hop this time... how can I do it ?
<1> ssh I mean
<2> forward to localhost on machine B, then on B, do ssh -L tmpport:D:port C
<3> there's another way, but I'd have to refer to the man page
<1> tnx. guys
<1> trappist : ssh way ? or through iptables .. man ssh ?
<3> man ssh :)
<1> ok. tnx.
<4> are you talking about ssh tunneling?
<5> is there anything avaliable that can replicate connection tracking info. like something that would work with a vrrp router durring a failure/takeover
<6> as I can redirect log to a file?
<7> see the ULOG target, otherwise check your syslogd settings.
<8> What does the [!] do if p***ed with -i ! eth0. It says in the manual that it inverts the interface. What does that mean ?
<6> rob0: -j LOG --log-prefix "message" >> file
<6> rob0: it's okey?
<7> "If the incoming interface is not eth0 ..."
<7> selkfoster: 19:59 < rob0> see the ULOG target, otherwise check your syslogd settings.
<6> ok thanks
<9> is there a QoS channel on efnet?
<9> im ***uming tc is the standard use tool for it?
<8> So if I want to LOG rule 'iptables -A <chain> -m state --state ESTABLISHED, RELATED -j ACCEPT' I would just create and identical rule and jump it to LOG --log-prefix "ACCEPTED_PACKETS:"
<10> hello, anyone familiar with rc.firewall or any other script for ip masquerading? I have 2 network cards, one of them connected to the real world, and i need to share this with the 2 other computers on the second one. like ICS
<11> hello
<8> This program rules
<11> does anyone know the ports to open to get a dhcp server working ?
<11> my firewall file start with default drop policy for all
<11> dhcp server can't work
<8> ## Insert connection-tracking modules (not needed if built into kernel).
<8> # insmod ip_conntrack
<8> # insmod ip_conntrack_ftp
<8> ## Create chain which blocks new connections, except if coming from inside.
<8> # iptables -N block
<8> # iptables -A block -m state --state ESTABLISHED,RELATED -j ACCEPT
<8> # iptables -A block -m state --state NEW -i ! ppp0 -j ACCEPT
<8> # iptables -A block -j DROP
<8> ## Jump to that chain from INPUT and FORWARD chains.
<8> # iptables -A INPUT -j block
<8> # iptables -A FORWARD -j block
