It gives correct IP addresses and subnet masks using DHCP DHCP is an Ethernet protocol and is not used in PPP. PPP will automatically get an IP address for you and the peer. PPP does not use subnet masks, as it is a point to point protocol, and there are only two addresses on the link - which don't even have to be on the same range. >but browsers cannot find any sites. So fix /etc/resolv.conf. In windoze, look at ipconfig ans see what it is using for DNS servers. >May be, such providers do not support UNIX like systems? (UNIX is not >so popular in our country :(, so it's possible). UNIX is popular - the ISPs don't pay their staff to answer questions from UNIX users. They are probably using Linux (or *BSD), but won't admit to it. >I using SuSE Linux 9.1, with KDE 3.2 >resolv.conf is empty Is there a file /etc/ppp/resolv.conf ? What's inside it? >KPPP is setted up to localhost domain and automatic DNS setting "automatic DNS setting" has the broken tool called kppp using the "usepeerdns" option to pppd. See the pppd man page. Perhaps your ISP doesn't support that option, as it was developed by microsoft, and is not an official part of the ppp protocol. See RFC1661 and RFC2153. Old guy .
