No it's not. Every Unix system has this.
First a lot of connects to rshd:
>Feb 22 15:04:39 nasa in.rshd[447]: connect from 200.231.198.213
>Feb 22 15:04:39 nasa rshd[447]: Connection from 200.231.198.213 on illegal
>port
Then inetd refuses connects to the rshd port. Oh and others too I see,
you are really being bombarded here:
>4:58:31 nasa in.telnetd[286]: refused connect from 200.231.198.213
>4:58:31 nasa in.telnetd[287]: refused connect from 200.231.198.213
>4:58:31 nasa in.telnetd[288]: refused connect from 200.231.198.213
>4:58:31 nasa inetd[63]: telnet/tcp server failing (looping), service
>terminated
>5:04:38 nasa inetd[63]: shell/tcp server failing (looping), service
>terminated
>5:07:35 nasa inetd[63]: auth/tcp server failing (looping), service
>terminated
If you read the manpage of inetd you'll find out that if a service is started
more then 40 times in 60 seconds inetd will stop the service. Modern
versions of inetd should then restart the service after 2 or 5 minutes;
old versions did not do this!
Also in the manpage you'll find how to increase this limit if you are so
inclined.
