SUMMARY:ifconfig bad address during bootup

The problem turned out to be an entry in the nsswitch.conf file. The entry had been changed to

hosts: nis [NOTFOUND=return]


hosts: nis [NOTFOUND=return] files

Don't try this at home.

Thanks to all,



A Sparc 20 (Solaris 2.4) that's been running fine for over a year couldn't boot properly this morning. During execution of /etc/rcS.d/ the error "ifconfig bad address: thor" is displayed (thor is the hostname). Sunsolve says to look for bad characters in the hosts file or for extraneous files in /etc having extensions such as le0 that could mess up the script. Neither of these cases exist. We have managed to get the machine up by manually issuing the commands and replacing the host name with the ip address but I still can't figure out what's going on.

Any ideas?


p.s. The hosts file looks fine - localhost and all.
