[linux] Pripojenie do firemnej siete

[minka na host.sk]

Ahojte!

Snazim sa pripojit svoj notebook s RH 6.2 do nasej firemnej siete kvoli surfovaniu a downloadom. Vsetko su v nej Windowsy.

Funguje mi dhcp, dostanem adresu. 
eth0      Link encap:Ethernet  HWaddr 00:10:A4:B0:72:87  
          inet addr:192.39.181.101  Bcast:192.39.181.255  Mask:255.255.255.0
          UP BROADCAST RUNNING  MTU:1500  Metric:1
          RX packets:501 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:1509 dropped:0 overruns:0 carrier:1509
          collisions:0 txqueuelen:100 
          Interrupt:3 Base address:0x200 
Neviem, preco su tam tie chyby v TX paketoch.

Mam nastavene DNS servre...

nameserver 192.168.1.2
nameserver 192.39.181.17
nameserver 192.39.250.90
nameserver 129.227.38.94
posledne tri su firemne

... a default gateway
network
NETWORKING=yes
HOSTNAME="SK-BB-MINKA-NB"

Dalej:

127.0.0.1		SK-BB-MINKA-NB localhost.localdomain localhost

Celkovo to vyzera takto:

Pri pokuse otvorit web-stranku cez Lynx mi tcpdump pise zhruba toto:

21:18:56.064590 eth0 > arp who-has 192.39.181.1 tell 192.39.181.101 (0:10:a4:b0:72:87)

21:31:42.004294 eth0 > 192.39.181.101.1538 > 192.39.181.17.domain: 33713+ PTR? 255.181.39.192.in-addr.arpa. (45)
21:31:44.426110 eth0 B 26.03.2001

Este som tam mal nejaky riadok konciaci UDP, ale ten som nezachytil.
Kolega vravel, ze nasa siet nepusta UDP komunikaciu.(?)

Rad by som vedel, kde robim chyby, preco mi to nejde, pripadne, kde sa o pricinach docitam viac.
Vopred vdaka.
