A couple of weeks ago, when I was having trouble with my web server, I noticed that I don't have a localhost route:
]$ cat hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 lumcweb localhost.localdomain localhost 192.168.0.33 lumcweb.localdomain lumcweb 192.168.0.25 MossLinux MossLinux 24.94.162.101 smtpserver ]$ netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 169.254.0.0 * 255.255.0.0 U 0 0 0 eth1 default 192.168.0.1 0.0.0.0 UG 0 0 0 eth1
Yet my hosts files includes it. This server is running Fedora Core 2.
I can also ping the localhost just fine:
PING lumcweb (127.0.0.1) 56(84) bytes of data. 64 bytes from lumcweb (127.0.0.1): icmp_seq=0 ttl=64 time=0.071 ms 64 bytes from lumcweb (127.0.0.1): icmp_seq=1 ttl=64 time=0.063 ms 64 bytes from lumcweb (127.0.0.1): icmp_seq=2 ttl=64 time=0.060 ms 64 bytes from lumcweb (127.0.0.1): icmp_seq=3 ttl=64 time=0.063 ms
Should I be concerned?
