Subject: lots of tcp port 445 traffic
Date: Tue, 07 Dec 2004 00:54:08 +0800	[thread overview]
Message-ID: <41B48EB0.3030307@phreaker.net> (raw)

Hi,

I get lots of tcp port 445 traffic when I do a tcpdump -n port 445, 
could it be an attack?

I check on the syslog files at /var/log/syslog, it shows this as below: -

Dec  7 00:36:40 fw01 kernel: Neighbour table overflow.
Dec  7 00:36:46 fw01 kernel: NET: 32 messages suppressed.
Dec  7 00:36:46 fw01 kernel: Neighbour table overflow.
Dec  7 00:36:51 fw01 kernel: NET: 27 messages suppressed.
Dec  7 00:36:51 fw01 kernel: Neighbour table overflow.
Dec  7 00:38:14 fw01 kernel: NET: 6 messages suppressed.
Dec  7 00:38:14 fw01 kernel: Neighbour table overflow.

When I try to ping my router IP address, I get this message below: -

connect: No buffer space available

I did tried running the below command and it seems not helping much: -

iptables -I cus2jarwan -p tcp --dport 445 -j REJECT --reject-with tcp-reset

or

iptables -I cus2jarwan -p tcp --dport 445 -j DROP

How can I stop this tcp port 445 traffic?  Or how can I prevent it?

Regards,
ro0ot
