How to remove telnet from OS X 10.8 ??

[deanjo]

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.

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

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.

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.
