you can also use inetd/xinetd |
| 10 |
|
| 11 |
for inetd you add line like this: |
| 12 |
1521 stream tcp nowait nobody /bin/echo /bin/echo "It worked" |
| 13 |
to /etc/inetd.conf |
| 14 |
|
| 15 |
and then send SIGHUP to inetd process |
| 16 |
|
| 17 |
with xinetd it is similar, just you a add a new file with different syntax |
| 18 |
|
| 19 |
this is permanent (works until you remove that line and let inetd to |
| 20 |
reread its configuration), so it is a quite good method how can you (for |
| 21 |
example) disable ping for certain server, but still have a way how to |
| 22 |
'ping' it using telnet (available everywhere) for support people, etc ... |
| 23 |
|
| 24 |
there are reasons for disabling ping (icmp in general) because of security |
