I tried following this guide to setup chrooted ssh: http://www.howtoforge.com/chroot_ssh_sftp_fedora7 I tried manual and script methods. I was never able to get it to work. I never touched my 'perforce' user, but now I am unable to connect to my perforce server running on the same machine. "WSAEHOSTUNREACH" I have no idea where to start. The p4d is running and I can ssh into the box.
My bad, turning off iptables gets around this. I know I didn't touch iptables at all, but I don't see how this could be related to the ssh stuff I was playing with.
These iptables look totally foreign to me aside from opening port 22 and 80, have I been hacked? Or is this normal... 224.0.0.251 means nothing to me. Code: ]$ sudo cat /etc/sysconfig/iptables # Firewall configuration written by system-config-firewall # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m udp -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT -A INPUT -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT -A INPUT -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT
It's used for multicast DNS: http://www.usenet-forums.com/linux-networking/68999-what-who-uses-udp-port-5353-a.html
