Fedora issues (network)

[Dave Sampson]

hey Folks,

I think I am on the steep learning curve of SElinux issues. Not all of 
my problems are rooted in it but keep in mind that if everything seems 
ok then SElinux might be problematic.

I am runnning Fedora core 5
I have a moderate level of knowledge with Linux
I prefer RPM's but will compile where needed

network setup

modem/router Speedtouch 585
  Name: Avalache
    Required ports are being forwarded where needed for various 
services. I still might have missed something
2 computers
telemark: workstation/laptop
    Eurocom Viper M270s
snowdrift: server
    Compaq Deskpro

For all the challenges bellow I have read the MAN pages, found howto's 
read about fedora cases and non-fedora cases, and have asked peers where 
possible.

Some areas of trouble

SAMBA/NFS:
When SElinux on the server is off they work. when it is on they fail. 
The server and directories are visble in browsers, but accessing the 
directories fail. So is this somthing I can rectify in Desktop >  Admin 
 > Security > Selinux >  modify > Samba?
    telemark: Allow users to login to CIFS directories is checked
    snowdrift: Same

Both computers have SAMBA allowed for firewalls and router is passing 
the documented ports.

Any ideas?. Or maybe there is a post already (although I didn't find it)

VNC/Remote desktop

Follwed the fedora and VNC documentation. this includes setting up the 
vnc text files. let me know if you want them posted and which ones are 
important. Maybe I have one overriding another?
    telemark: Server of monitor 2
    mobile: Server on monitor 2

When I use vncviewer localy it works, when I got from telemark to 
snowdrift then I result in no route to host. although I can ping both 
the name snowdrift and its ip and get a positive response.

WIRELESS:
Alright here is a kicker... I have an ACX100 (D-link Dwl 650+) chipset 
for wireless card. I am using windows drivers through ndiswrapper

It works, but is combuersome. I use both a wired and wireless conection. 
my goal is the switch on the fly. i have tried hotplug, ifplugd and a 
bunhc of other stuff but am lost.

Currently when I boot my computer without a network connection I need to 
run a script first
#!/bin/bash

echo bringing up WLAN Device
sudo /sbin/ifconfig wlan0 up
echo ...
sudo /sbin/iwconfig wlan0 enc #########
echo ... ...
sudo /sbin/iwconfig wlan0 essid Avalanche
echo ... ... ...
sudo /sbin/dhclient wlan0
echo ... ... ... ...
echo finished bringing up WLAN Device
#End

Then I go into the network panel a activate network connection manually. 
there are two errors in the activation script looking for SLEEP commands.

Then it is going. What I want to be able to do is unplug my wired 
network and plug in pcmcia card and voila a seamless transport (ok I 
don't expect to keep a secured connection). Where to?

Those are my network related questions. I figured one thread could 
multiply instead of starting all the troubles in different threads.

Thanks for any help.

Cheers
