Hello all, I think I may have found a bug, but it may just be a problem with my understanding of how networking works. I have a machine running 2.0.27 and I can ping the machine www.analogic.com. However, if I try to telnet to the same machine I get an error message about there being no route to the host:
sailboat> ping www.analogic.com PING www.analogic.com (204.178.41.218): 56 data bytes 64 bytes from 204.178.41.218: icmp_seq=0 ttl=244 time=590.3 ms 64 bytes from 204.178.41.218: icmp_seq=1 ttl=244 time=34.3 ms --- www.analogic.com ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 34.3/312.3/590.3 ms sailboat> telnet www.analogic.com 80 Trying 204.178.41.218... telnet: Unable to connect to remote host: No route to host
I am assuming that there must be a route to the host in order for ping to work.
Here is the output of strace:
socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 4 getuid() = 502 setuid(502) = 0 connect(4, {sin_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr("204.178. 41.218")}, 16) = -1 EHOSTUNREACH (No route to host)
and the output of route: Kernel routing table Destination Gateway Genmask Flags MSS Window Use Iface localnet * 255.255.0.0 U 1500 0 19891 eth0 loopback * 255.0.0.0 U 3584 0 541 lo default uncw-gw.gate.un * UG 1500 0 25797 eth0
