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

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?

You could just enable root user in OS X, log in as it and then edit your files from a comfort of a gui if you wish and disable it after you are done your changes.

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

There is also emacs and nano which come with OS X.

Drop to terminal,

sudo networksetup -setv6off Wi-Fi
sudo networksetup -setv6off Ethernet

thanks gbudny that worked, editing with text edit makes everything much easier


What I need to ask is what services should I block:

telnet

ssh

I need to block that windows one samba because the hackers use that too.

anymore obvious ones?

I think you should block Telnet

"Because it isn?t as secure as SSH, Telnet access isn?t enabled by default"

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.
