We are having an issue with our Debian Server, we host several services on it each using several ports (all are open in iptables), all users can connect to these fine, except osx users.
We have got the users to ping / traceroute the server, but it cannot even ping the IP, however pinging from Windows or Linux works fine.
This is really strange, i cannot see what is causing it.
This is not on a subnet, but over a internet network. result from OSX when traceroute:
traceroute to x.x.xx.xxx (x.x.xx.xxx), 64 hops max, 52 byte packets 1 * * * 2 * * traceroute: sendto: No route to host traceroute: wrote x.x.xx.xxx 52chars, ret=1 * traceroute: sendto: Host is down
Result from unix & windows is a standard sucessful ping at 11ms
When attempting to ping from OSX:
PING x.x.xx.xxx (x.x.xx.xxx): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 Request timeout for icmp_seq 3 ping: sendto: No route to host Request timeout for icmp_seq 4 --- x.x.xx.xxx ping statistics --- 6 packets transmitted, 0 packets received, 100.0% packet loss
