hi all!
i'm using RH 6.0 with kernel 2.2.14,
glibc 2.1.1, bind-8.2-6.
i tried to make a ppp link for internet coenctivity.
the ppp link was ok but i couldn't resolve names
within lynx, netscape or LAN.
the problem seems to be at dnsquery.
when i call dnsquery in DEBUG mode it can talk to nameservers and
give results, but a simple call fails. I had to make it seem that
dnsquery is called normally but, in fact, is called in debug mode
( a script named dnsquery which calls the original program with
-d option and rest of arguments.... ). From that point my ppp
link gives internet conectivity in LAN !!!
I configured some time ago a similar RH 6.0 system and that
problem didn't appeared.
So, I'm asking you, why this problem ?
Software environment:
(i attached to this mail my configs so you can take a look )
and some strace outputs from dnsquery runs )
- resolv.conf
- nsswitch.conf
- host.conf
- outputs from route, ifconfig, ldconfig
- outputs from strace for dnsquery run w/o debug option !
TAKE A LOOK at dnsquery without debug !
it doesn't EVEN OPEN resolv.conf !!!!
why ldconfig gives me those messages, how can i get rid
of them and what does it mean "SONAME" ( i found some
vague explanations about this... ) ??
TIA for any help!
C-ya,

#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# nisplus or nis+ Use NIS+ (NIS version 3)
# nis or yp Use NIS (NIS version 2), also called YP
# dns Use DNS (Domain Name Service)
# files Use the local files
# db Use the local database (.db) files
# compat Use NIS on compat mode
# [NOTFOUND=return] Stop searching if not found so far
#
# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd: db files nisplus nis
#shadow: db files nisplus nis
#group: db files nisplus nis
passwd: files nisplus nis
shadow: files nisplus nis
group: files nisplus nis
#hosts: db files nisplus nis dns
#hosts: files nisplus nis dns
hosts: files dns nisplus nis
# hosts: dns
services: nisplus [NOTFOUND=return] files
