Guest Earthworm Jim Report post Posted May 2, 2008 So I'm giving Mandriva a go, and I've run into a weird snag - I've got two machines - the one I'm typing on now & another one right next to it which can't talk to each other. I can ping anything outside of my local network (ie - www.yahoo.com) from either machine. I can come here & post this question from etiher one. But they don't see each other pings & ssh's both hang (ssh is in connect, strace doesnt't want to attach to ping for some reason): ssh: Process 14993 attached - interrupt to quit connect(3, {sa_family=AF_INET, sin_port=htons(22), sin_addr=inet_addr("192.168.15.104")}, 16 I've got my security settings cranked down to "Poor" on both sides, verified "disabled = no" in xinetd.d/ssh.conf on both sides, verified that net.ipv4.icmp_echo_ingore* were all set to 0 in /etc/sysctl.conf, and obviously I'm here posting from one of the affected machines. When I had Fedora / windows systems on this same router they could see each other just fine. But now that I'm all Mandriva, nobody can see anybody on the local network What gives?

If it is there, then it will be a firewall problem with shorewall/iptables being used on these machines. You can easily test this once the port 22 has been verified for listening and accepting connections, and just doing: service shorewall stop service iptables stop and then try to connect to SSH and ping.

scarecrow 0 Report post Posted May 3, 2008 (edited) Can you do some cat /etc/hosts as well as cat /etc/hosts.allow cat /etc/hosts.deny and finally cat /etc/ssh/sshd_config in both machines? Edited May 3, 2008 by scarecrow Quote Share this post Link to post Share on other sites
