 |
|
hi,
when i start ping (or tracerout, or any icmp protokol using program) i get:
# ping
ping: unknown protocol icmp.
??
But its getting worse, during compiling perl i now get during test:
lib/io_sock..........IO::Socket::INET: Bad protocol 'tcp' ...propagated at lib/io_sock.t line 37.
FAILED at test 1
But most programs still seem to work fine (like this mozilla 1.0, which i''m using to post), network seems to be ok, too. Any clues ?

What does your /etc/protocols file look like? Sounds like it might be wacked out...

it was a wrongly configured nsswitch.conf  after a "strace ping" i saw ldap requests for the protocol, which is obviously wrong 
The reason was i did copy some nsswitch.conf for ldap auth from somewhere, and didn't look into it very deeply
but now i did remove the ldap settings from the network files, and everything works fine agian. even ldap auth |
