Yes I can connect anywhere from this server! There's also running apache, fpt, telnet etc.

And I administrate the server on console from another station, and often i open ftp on this server to download tar gzs like apache, php etc...

Just ask for namend.conf because i wans't sure about it. but when I do it manually by nslookup on the solaris box. I get all mx result diffrent hosts.
tryout for berlin.de

nslookup
> set quertype=mx
> berlin.de
Server: ns02.ch.abatos.com
Address: 143.99.32.11

Nicht-autorisierte Antwort:
berlin.de MX preference = 100, mail exchanger = zeus.nic.dtag.de
berlin.de MX preference = 10, mail exchanger = mx0.berlin.de

zeus.nic.dtag.de internet address = 194.25.1.124
mx0.berlin.de internet address = 195.243.105.32

so the dns resolver works...

also could I send Mails to my server via smtp... but it's belin.de like my nslookup example. I get a postmaster message that it could find the host, but by nslookup, on the same server... it find the host!!! There's a brocken pipe between sendmail and dns resolving... im a bit confused about that!

So I don't know what I do wrong. And I'm not new to unix. So where are additional config for sendmail to dns resolv. I don't find more than sendmail.cf resolving entrie.

thank you!
.... i dont really what's wrong.

NAME
desproxy-dns - DNS for dynamic connections SYNOPSIS
desproxy-dns dns_server proxy_host proxy_port OPTIONS
None DESCRIPTION
If you have direct DNS access then you don't need to do anything else. You know you have direct DNS access if you can resolve host names to IP addresses. NOTE: as desproxy-dns listens in port 53 (which is less than 1024) you may need administrator privileges to exec desproxy-dns (in fact if you are running UN*X, you actually have to run desproxy-dns as root). OK, so you have a dns server accessible now. But your computer doesn't know anything about that. You must configure your network accordingly (again, need to be root in UN*X). Edit /etc/resolv.conf and add the line "nameserver 127.0.0.1". You don't have to restart anything. Just test ping and see if it works. ENVIRONMENT
None. FILES
None. SEE ALSO
