When ever I try to ping anything (root or otherwise) I get:

Yep, listed second. Here's the full version of it:

check your firewall rules. If you have any chains dealing with icmp packets, you can get that message as well. That's why I haven't implemented any icmp rules yet, because I still like to use ping and traceroute as well.

I have have made sure I have the most updated version of iptables. When i do iptables -L I get this.

[code]
[root:1@ 15:31:06~]>> iptables -L
modprobe: Can't locate module ip_tables
iptables v1.2.7a: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
[/code]

Haveing little iptables experience I figure this is the case because I'm not running iptables. Got a firewall I'm behind and trusting till I get iptables figured out. ( I know the guy who runs the firewall knows much more about iptables than I do.)

double/tripple check your nsswith.conf ... I once did install LDAP auth and had the same problem ... so check if your nsswith.conf has something like this:

services: files
networks: files

Thanks mglauche, that's a great direction I hadn't though about yet. It looks ok from what you said, but I'm not very familiar with this.

Here's my nsswitch (-headers). I did recently try to make changes including ldap (as you can see). I'm trying to setup an SAMBA/LDAP PDC-killer, which I'm still working on i.e. It doesn't work yet, maybe this has something to do with it.

use only the first 3 for ldap, change the rest to "files" as there's no real need to store them in ldap anyway (they usually should not change that often, and it makes the whole thing more complicated)

having services to "ldap .." is the source of your problem

I removed ldap from the services line, and the network line also. Now is there a service I need to restart to refresh this info, cause I'm getting the same error still.

Thanks for your help.
