when it comes to firewalling, i'm still very much a newbie but i portscanned myself from my server @home and got one result and portscanned the same server from work and got a different result this shouldn't happen right? what am i missing?
it may be worth mentioning that i recently added the following line to my ipchains file in hopes of allowing ftp traffinc in and out properly. before, i'd always get the message "falling back to PORT...." when i tried to ftp in using ncftp: -A input -s 0/0 20 -p tcp -y -j ACCEPT it worked, but i don't really know what it did. i don't know what it means really i just copied the line lokkit had written for port 21 and changed the portnumber i'm stumbling around in the dark here... help?... anyone? i've attached the results from both scans: from my server @home: ----------------------------------------------------------------- [root@gunslinger root]# nmap my.home.ip.nnn -sT Starting nmap V. 2.54BETA22 ( www.insecure.org/nmap/ ) Interesting ports on (my.home.ip.nnn): (The 1539 ports scanned but not shown below are in state: closed) Port State Service 21/tcp open ftp 22/tcp open ssh 80/tcp open http Nmap run completed -- 1 IP address (1 host up) scanned in 1 second [root@gunslinger root]# nmap 127.0.0.1 -sT Starting nmap V. 2.54BETA22 ( www.insecure.org/nmap/ ) Interesting ports on gunslinger.tenagra.ca (127.0.0.1): (The 1538 ports scanned but not shown below are in state: closed) Port State Service 21/tcp open ftp 22/tcp open ssh 25/tcp open smtp 80/tcp open http from my work machine: ----------------------------------------------------------------- [root@hephaestus root]# nmap -sT my.home.ip.nnn Starting nmap V. 2.54BETA22 ( www.insecure.org/nmap/ ) Interesting ports on (my.home.ip.nnn): (The 1538 ports scanned but not shown below are in state: filtered) Port State Service 20/tcp closed ftp-data 21/tcp open ftp 22/tcp open ssh 80/tcp open http _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
