sysctl command



Normally ... you have it installed, you will not let SNP tools .. still it ....?? telnet
Let's telnet and ftp to the port to shut it ...^^
Unless your server is multi-user ... and people feel more convenient telnet port .. it does not matter to do with friends ..
As for the security part of it to think of ...>__< ..

Ado ...
1. To amend / etc / inetd.conf file

In the front you will see under this part ...
# Ftp stream tcp nowait root / usr / libexec / ftpd ftpd-l
# Telnet stream tcp nowait root / usr / libexec / telnetd telnetd-h

Remove with # that for the sake of this feature ... obviously I will mark it in blue ...

2. Inetd restart

Method 1: # kill -1 `cat / var / run / inetd.pid`
Method Two: # ps ax | more to find inetd-wW .. look at some of its pid then # kill -1 PID
Method 3: # reboot

3. Testing ..
Then use telnet ohaha.ks.edu.tw .... Can not you find telnet connect to your computer ...^^

4. Follow-up ..
In case you go back on the ... re-file the # inetd re-run inetd can be removed .. ..

5.inetd.conf new part (new installation)
# SNP 0.91
ptelnet stream tcp nowait root / usr / local / libexec / ptelnetd ptelnetd
prlogin stream tcp nowait root / usr / local / libexec / prlogind prlogind
pftp stream tcp nowait root / usr / local / libexec / pftpd pftd
ppasswd stream tcp nowait root / usr / local / libexec / ppwdd ppwdd
#
6./etc/service new part (new installation)
#
# SNP 0.91
#
ptelnet 970/tcp
prlogin 971/tcp -> If your machine has a firewall, then separated
pftp 972/tcp Please do not forget to use the port to open your Oh ....^^
