i tried running a search but i didnt get back anything clear, so here it is
what port do samba servers run on???
thanks, and sorry if its against the rules or anything :\

i guess they re running on the std netbios ports 135 137 139 .. are nt they ?

Yes, try google "samba ports" for more info.

then is there any scanner for linux taht can detect those samba systems ?
or maybe is there a distinct port that is used only for samba? is there?

Try google "samba scanner, linux".
For your second question about distinct ports, no.
137 through 139, inclusive. Both udp and tcp.

samba uses all the ports that cifs and netbios uses, off the top of my head that would be 135 137 138 139 445 (check /etc/services for the more athoritative answer), your best bet would be to use the latest greatest nmap with the -sV switch to identify the service running on that machine and of course you would want to do some os identification because nobody runs samba on a windows box I recomend the use of xprobe as a quick and easy way to fingerprint the os

yes i'm ok with 135 137 138 139 and 445 !!

i have its samba scanner and exploit together . for command to run samba type ./asmb xxx.xxx
and it will scann that range.
And when u get shell must pach it and run vckit to get pass... and i think that exploit is only for linux
