dhcpc & R.H. 5

[Robert Heryan]

Zdravim,
potreboval bych trochu pomoci. Mam R.H. 5, jede mi sit, ip adresu
ziskavam z
DHCP serveru (W NT). Muzu pingovat jakykoliv pocitac v siti (nejen
ping), ale nejak
nemuzu pingovat sam sebe. Pise to Unknow host. Na DHCP servru jsem
zjistil,
ze adresa, kterou mi pridelil, nema prirazene jmeno. V W95 se o to
udajne stara nejakej
WINS (asi Black :-)). Posledni dobou jsem do toho hodne stoural, a tak
se stalo,
ze DHCPC hlasi "failed", ale vse je pri starem. Mam pocit, ze jsem neco
zmenil v ifup
je tam komentar zacinajici RRR. Nemohl byste se nato vsechno nekdo
mrknout?
Mozna by stacilo, kdyby jste mi nekdo poslal zmineny ifup
(/etc/sysconfig/network-scripts/ifup).
Za kazdou trosku budu vdecny.
