Hi All! I've been to www.grc.com, and when my Apache port is blocked I'm getting true stealth mode. Excellent site! The only thing that concerns me is this: when I do netstat -lt (on SuSE 8.1 pro), netstat tells me that SMTP is waiting for incomming tcp connections. topaz:~ # netstat -lt Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address tcp 0 0 *:www-http *:* LISTEN tcp 0 0 localhost:smtp *:* LISTEN I'd rather SMTP didn't listen for incomming connections - even though port 25 is fully stealthed. I don't run a mail receiver/server. I collect all my email from my ISP's mail server, using fetchmail. I have tried disabling SMTP, using postfix stop, but fetchmail has problems collecting and delivering my mail locally with this. Is there any way to tell SMTP to work with fetchmail, WITHOUT listening for incoming tcp connection requests from port 25? Your help much appreciated. Regards Keith Roberts. P.S. I managed to get X11 to stop listening for incoming connections from port 6000. Here is my script: #!/bin/sh # # /usr/X11R6/bin/runX-no-listen # a simple script wrapper to start the X11 server # without listening for incoming tcp connections. # last updated 2003-08-13 startx -- -nolisten tcp # end of wrapper
