Imam 2 lan karti no mai raboti samo ednata. Kato dam
 ifconfig eth0 se izvezhda informatsiia za kartata, no pri
 ifconfig eth1 ne namira ustroistvoto. Kak da si aktiviram
vtorata lan karta.

Predi da stignesh do nastroikata na samiia interfeis (eth0,
 eth1 
etc.), triabva modulut na iadroto, koito e za suotvetnata
 mrezhova 
karta, da e zareden. Kakva e vuprosnata mrezhova karta? S kakvo 
iadro si?
  

Sled kato modulut veche e zareden i se uverish, che e tochno
 tozi, 
mozhesh da go vuvedesh v /etc/modules, za da se zarezhda avtomatichno.

 Iskam samo da dopulnia, che pri razlichnite distributsii se
 slaga suotvetniiat modul na razlichno miasto. Ako izpolzvash
 slackware e dobra ideia da slozhish modula v
/etc/rc.d/rc.netdevice
 Pri Debian, RedHat e dobra ideia tam kudeto ti e kazal N.
 Antonov. Sushtoto se otnasia i za statichno up-vane na mrezhoviiat
 interfeis. Vsiaka distributsiia si ima opredeleno miasto za
 zadavane na IP adres, mrezhova maska, default gateway i t.n.
 Naprimer pri slack 9.1 si ima edin fail
 /etc/rc.d/rc.inet1.conf, pri Debian /etc/network/interfaces
ako se ne luzha!

Tochno taka, sled kato e zareden pravilniiat modul,  interfeisite se 
opisvat v /etc/network/interfaces i se  aktivirat s komandata:  
/etc/init.d/networking restart  Ako iskash instrument za nastroika 
na mrezhovite interfeisi,  mozhe da si instalirash etherconf. 
Prenastroikata im stava s  povtorno izvikvane na konfiguratsionnata 
komanda:  dpkg-reconfigure etherconf

 Mersi mnogo za pomoshta i dvete lan karti trugnaha(dobavih
 sis900 v /etc/modules), no sega ima drug problem tova e
sudurzhanieto na /etc/network/interfaces

 # /etc/network/interfaces -- configuration file for ifup(8),
ifdown(8)

# The loopback interface
auto lo 
iface lo inet loopback

 # The first network card - this entry was created during the
Debian installation
auto eth0
iface eth0 inet static
address 10.11.164.2
metmask 255.255.255.252
broadcast 10.11.164.3
network 10.11.164.0
gateway 10.11.164.1

#Internal interface SIS900
auto eth1
iface eth1 inet ststic
address 192.168.0.1
netmask 255.255.255.0
broadcast 192.168.0.255
network 192.168.0.0

 no sled kato Debian startira lan kartite niamat prisvoen IP
adres i triabva da gi nastroivam s ifconfig

 Oburni vnimanie na reda auto. Tam triabva da izredish
 niterfeisite, koito da se vdigat avtomatichno. Znachi triabva
da pishe:

auto lo eth0 eth1

T.e. mahni dolnite auto eth0 i auto eth1 i gi naredi otgore na purviia red sled lo.

 Kato dobavi tova v /etc/network/interfaces restartira li
mrezhovite interfeisi s /etc/init.d/networking restart?
 Vse pak triabva da se izchete na novo faila. Sushto taka ako ne
 si dobavil v /etc/network/options e dobre da napravish
 slednoto ip_forward=yes i syncookies=yes. Tova e za da kazhesh
 na sistemata da prehvurlia trafika ot ediniia na drugiia
 interfeis. Taka shte mozhesh da polzvash internet zad tazi
 mashina. A drugoto razreshava pone niakakva minimalna zashtita ot
 DoS ataki. Sushto taka proveri dali vuv faila
 /etc/network/ifstate i /etc/network/spoof-protect figurira
 sled eth0 i eth1. V ifstate suotvetno eth1=eth1. Tozi fail
 se obnoviava v zavisimost ot auto zapisite v interfaces. I ne
 e nuzhno vsichki interfeisi da gi dobaviash v reda auto lo.
 Failut se izchita i analizira iztsialo, taka che nachina po koito
 si gi dobavil sushto e pravilen, a i spored men e po-nagleden
 i lesen za chetene, a uveriavam te chel sum kakvi li ne
 programi, za koito niama da komentiram kak sa napisani, no
 ako na tozi koito e pisal tova mu e bilo udobno shteshe da
 programira samo na edin red. Za tova i skriptovete e hubavo
 da si budat dobre podredeni. Proveri vse pak tezi nastroiki.
 Mezhdu drugoto vupreki, che ifstate se generira ot sistemata
 tova ne oznachava, che ne mozhesh da si dobavish svoi red tam.
Naprimer ti da si napishesh eth1=eth1.
 Ami ne se seshtam drugo kakvo da kazha, osven che sled vsiaka
 takava promiana e hubavo da restartirash mrezhovite interdeisi
s reda, koito ti pisah v nachaloto.
Uspeh!!!

 SHTe probvam i tova koeto napisa Grigor Lekarov no ako ne
stane ostava samo edno

pravia fail ethconfig v /etc/rc.boot/ sus sudurzhanie
#!/bin/sh
ifconfig eth0 10.11.164.2 netmask 255.255.255.252
ifkonfig eth1 192.168.0.1 netmask 255.255.255.0
route add default gw 10.11.164.1
i gotovo

 i gotovo ama ne. Kato napravia tova koeto napisah KDE-to ne
 mozhe da startira, a kato izpulnia /etc/init.d/networking
restart

debian:~# /etc/init.d/networking restart

done.

predpolagam che problema e v tova no ne znam kak da go opravia

 Imash niakakva greshka na 16-ti red v /etc/network/interfaces.
 Niamashe da e zle da poustnesh tseliia konfiguratsionen fail za da
vidim kakvo tochno ne e nared tam.
 I oshte neshto. Vuzmozhno e da vurnikne greshka ako suzdadesh faila
 pod vinboz editor ponezhe toi si slaga v kraia ne reda simvoli
 0x0D, 0x0A ili v ASCII 13, 10. Po printsip v Linuks krai na
 red se belezhi samo s 0h0A. Za tova poniakoga
 konfiguratsionnite  skriptove ne se chetat pravilno. Spored
men e dobre da dadesh da vidim kakvo ima na red 16 v skripta.

Opravih greshkata no samo vtorata lan karta se startira

 Imash greshka v red 10. Triabva da e netmask, a ne metmasc. Za
 tova ne ti raboti purviia interfeis. Opravi tozi red i
restartirai interfeisa. Veche vsichko triabva da e nared.
Uspeh!!!

 Prav si tova beshe. Mersi mnogogo za pomoshta na vsichki. Mai
triabva da pisha po vnimatelno konfiguratsionni failive. :-)

 E, vse pak Linuks ne e kato vinboz i triabva malko poveche da
 se vnimava pri konfiguriraneto mu. Veroiatno za tova vse oshte
mnogo ot vurlite vinboz potrebiteli ne haresvat Linuks.
 Na men ne e nuzhno da blagodarish. Kazhi samo edno CHRD. Tova
stiga ;-)
 Nadiavam se ot tuk natatuk po-malko trudnosti s Debian da
imash. Tova e naistina dobro distro :-)
 Aide az prekratiavam rabota i spiram i neta, che gosti me
chakat :-)

 Takam Vie dobre ste sa opravili ama i az imam podoben
 problem ne mi zasicha lan kartata (tiliks - debian baziran)i
 pishe che ne mozhe da chete /etc/network/interfaces kak da go
oravia nov sum obiasnete mi kato na maloumen :)
