When I run a portscan with nmapwin to my linux box form the internet it shows me the following ports as open:
[...]
23/tcp open telnet 25/tcp open smtp [...]
The rest is definitely blocked by the firewall rules (only to outside interface). The firewall log shows that the ports are blocked. I see the portscan and I see that, for example, Port 25 is denied.
Maybe the mnap of this host is just broken or such? I use REJECT (also ipchains) as policy, and mnap from outside shows what I expect.
Wired: On Port 10000 i've webmin running only reachable from the inside. Why does nmap show snet-sensor-mgmt ????
What kind of policy do you use for reject/deny and what type of scan? What happens when you i.e. telnet to your box? With REJECT, I get a connection refused immediatly.
Why shows nmapwin (and other port scanners) that so many ports are in the state OPEN???
Maybe it's broken... oki, Steffen -- Dieses Schreiben wurde maschinell erstellt, es trägt daher weder Unterschrift noch Siegel.
