VMWare, Windows 2000 host, Red Hat 9.0 guest, virtuelna lokalna mreza, fantomski otvoreni portovi.konfiguraciju vidite iz subjecta... evo onoga sto vraca netstat -tau u linuxu:
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 *:ftp *:* LISTEN
tcp 0 0 *:ssh *:* LISTEN
tcp 0 0 192.168.192.129:ssh 192.168.192.1:1184 ESTABLISHED
udp 0 0 *:bootpc *:*
Znaci otvoreni su samo port 21, 22 za incoming konekcije.
Firewall u linuxu nije instaliran.
Medjutim... LANGuard Network Security Scanner 3.2 u Windowsu 2000 vraca ovo:
21 - Ftp => File Transfer Protocol
22 - Ssh => Remote Login Protocol
25 - Smtp => Simple Mail Transfer Protocol
110 - Pop3 => Post Office Protocol 3
68 - bootpc => Bootstrap Protocol Client
111 - RPC => SUN Remote Procedure Call
143 - imap => Internet Message Access Protocol
445 - Microsoft CIFS => Common Internet File System
517 - talk
1167 - phone => Conference calling
1434 - ms-sql-m => Microsoft SQL Monitor
2049 - nfsd => Network File System daemon
Dakle postoji jos mnostvo "fantomskih portova", pored ocekivanih cije postojanje ja ne mogu da objasnim. (verovatno ce neko iskusniji imati sta da kaze na ovu temu)
Kada pokusam telnet 192.168.192.129 25 (ili 110), konekcija se otvori, ali samo na kratko!
Unapred hvala!
