How to remove telnet from OS X 10.8 ??

[Pallidus]

I know this is hardly the most appropriate forum but it's the only computer one I'm registered in and I don't frequent apple forums so my question is:


I would like to disable the ability to use the tenet command on the Mac OS X 10.8 terminal.

What do I have to do, what specific file do I have to delete ?? it's in system ? library->??

Also on mountain lion why is there no option to turn IPv6 off?? it only shows me link-local or wtf

Just throwing some ideas... I don't know macosx at all. Try locating telnet via "whereis" equivalent. Then move the binary out as "telnet_" and compile a dummy C binary, like
int main(void){return 0;}
and call it telnet; so every time telnet is called it always succeeds, but nothing really happens.

os x is just a rebranded bsd, terminal command seem to all work the same.


I found a way, I have to edit the 'services' file and put a # on telnet


but the fucking thing says 'You don't own this file'

I don't see how it's different from Linux. You need to edit it as root with "sudo".

I know Real the problem is that sudo nanoing the 'services' file on the terminal is a fucking pain

it has like 6000 lines and you have to arrow scroll etc...

is there any other way???

also what blocks should I block, telnet , ssh, but what others do hackers use for remote logins and code execution

basically I just need 80 and 443 all other ports can be blocked but # a million lines :/

The Firewall has a GUI, so use that instead if you want to block ports. The file you're trying to edit is for service processes, not ports.

You do not need to delete anything.

Make a backup copy of /etc/services, then simply block the telnet service ports with a comment “#.”

#telnet 23/udp
#telnet 23/tcp

He already said that in post 3.

I blocked ssh and telnet, now I have to find shit like samba and those services that the ukrainians so love to exploit.


to use nano in os x's terminal with a file the size of 'services' is a fucking pain....

is that 'vim' thing working in os x's terminal?

anyway to edit this file using a normal text editor?

Yes. However you can install a graphical version of vim for OS X:

Do you think about TextEdit?

sudo /Applications/TextEdit.app/Contents/MacOS/TextEdit filename
