>Description:
When booted single-user, if the network 'de0' is configured
ping fails with the following error:
PING 158.52.19.254 (158.52.19.254): 56 data bytes
64 bytes from 158.52.19.254: icmp_seq=0 ttl=255 time=1.585 ms
ping: failed to clear cached route: Network is unreachable
This occurs on the machine with the dmesg above, and on a
SparcStation 10 Model 30, and on a Tyan Tomcat I P133, so it
appears to be general
>How-To-Repeat:
boot -s
fsck
mount -a
ifconfig de0 `cat /etc/ifconfig.de0`
ping x.x.x.x <- local machine on same ethernet wire
The contents of ifconfig.de0 are:
inet shadow netmask 255.255.255.0 media 100basetx
>Fix:
Do not have a fix. Telnet works fine to the same ip address.
