Re: [CentOS] Inquiry:Problem with nmap

[hadi motamedi]

Thank you for your reply . Sorry that I was not exact on my previous message
. Actually , my CentOS host is @172.18.98.1 and the network element is @
172.18.0.1 . To this end , my host can ping the network element but when I
try to scan its ports to see which one is open the nmap cannot distinguish
and returned the message that I sent you . I hope this clarifies my
situation here .

I dont know your network structure, but in your last email it sounds if
you could ping the host and now it looks like you're dropping everything?

iptables -P INPUT ACCEPT

This will allow all input to your host.

Thank you for your reply . But still it cannot get through :
"
#nmap -sS -p 20-80 172.18.0.1
Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Note: Host seems down. If it is really up, but blocking our ping probes, try
-P0
Nmap run completed -- 1 IP address (0 hosts up) scanned in 91 seconds
"

[CentOS] Inquiry:Problem with nmap

[hadi motamedi]

Dear All
Can you please do me favor and let me know how can I solve my problem with
nmap , as described below :
"My CentOS server can ping the network element , but when I try to scan its
open ports to see which ones are open at now the nmap cannot distinguish
them and returned as they are being filtered :
#nmap -sS -p 20-80 172.18.0.1
Can you please let me know how can I modify my nmap command to get through ?
Thank you in advance
