I've been using the same mirabilis server for 2 years now (icq1.mirabilis.com), and it's on port 4000. I don't think they have changed it...
Hi, I went to the ICQ homepage and looked a few things up. Amazing what you can find when you look-) ICQ uses port 4000 for client to server stuff. But for peer to peer then it tries to use a port above 1024 [1023? I always forget] You can restrict the ports it tires to use. The problem is my firewall is somehow blocking peer to peer stuff. Sending messages back to the server works just fine but chat or direct messages have problems. Anybody care to look at the ICQ lines of my firewall and point out how stupid I am? # ICQ server (4000) # ----------------- ipchains -A input -i $EXTERNAL_INTERFACE -p tcp \ -s any/0 $UNPRIVPORTS \ -d $IPADDR 2000:4000 -j ACCEPT ipchains -A output -i $EXTERNAL_INTERFACE -p tcp ! -y \ -s $IPADDR 2000:4000 \ -d any/0 $UNPRIVPORTS -j ACCEPT ipchains -A input -i $EXTERNAL_INTERFACE -p udp \ -s any/0 $UNPRIVPORTS \ -d $IPADDR 4000 -j ACCEPT ipchains -A output -i $EXTERNAL_INTERFACE -p udp \ -s $IPADDR 4000 \ -d any/0 $UNPRIVPORTS -j ACCEPT # ICQ client (4000) # ----------------- ipchains -A output -i $EXTERNAL_INTERFACE -p tcp \ -s $IPADDR $UNPRIVPORTS \ --destination-port 2000:4000 -j ACCEPT ipchains -A output -i $EXTERNAL_INTERFACE -p udp \ -s $IPADDR $UNPRIVPORTS \ --destination-port 4000 -j ACCEPT ipchains -A input -i $EXTERNAL_INTERFACE -p udp \ --source-port 4000 \ -d $IPADDR $UNPRIVPORTS -j ACCEPT I think the problem should be in the server section. Maybe the second line with a ! but what I don't understand is the error messages I'm getting Sep 27 10:10:09 barley kernel: Packet log: input DENY ppp0 PROTO=6 other person:1198 me:2443 L=48 S=0x00 I=54283 F=0x4000 T=113 SYN (#107) Now I'd understand if it was the other way around but then I might just be confused.
