Disable Echo Reply
2007-12-25 1:03:00
I keep getting the following on several of the systems in my
network. I have commented out the echo lines in both the
/etc/inet/services and in /etc/inet/inetd.conf but I can not
seem to stop the DOS on my network. The below output goes on
for several hours and has basically put the network at a crawl.
The systems are running Solaris 8 and 9 different updates.
Anyone else run into this problem, and what else can be done to
prevent echo replys from the systems inside the network.
TIA,
