Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Thanks to comment if that works or not...

If you have already typed that snippet or you know you already have IO::Interface::Simple perl module, you can type only the last command :

perl -e 'use IO::Interface::Simple; my $ip=IO::Interface::Simple->new($ARGV[0]); print $ip->address,$/;' <INTERFACE>

( The first perl command will install the module if it's not there already... )

Alternatives

There are 5 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

Doesn't work on MacOS X.

Correction: It might work if I install the required module. Thanks for sharing IO::Interface::Simple. I'll check it out.

Comment by putnamhill 363 weeks and 6 days ago

Doesn't work in Solaris 10.

Comment by billbose 363 weeks and 5 days ago

What is the output of

perl -e 'use IO::Interface::Simple; my $ip=IO::Interface::Simple->new($ARGV[0]); print $ip->address,$/;' <INTERFACE>

?

Comment by sputnick 363 weeks and 5 days ago

"cpan" command doesn't exists on Solaris, maybe on OsX too, so you should install the module :

perl -MCPAN -e 'CPAN::Shell->install(IO::Interface::Simple)'

and then use the last command :

perl -e 'use IO::Interface::Simple; my $ip=IO::Interface::Simple->new($ARGV[0]); print $ip->address,$/;' <INTERFACE>
Comment by sputnick 363 weeks and 4 days ago

You can try that one if you have quoting problems on certani Unices :

export x=IO::Interface::Simple; perl -M$x -e1 &>/dev/null || cpan -i "$x"; perl -M$x -e 'my $ip=$ENV{"x"}->new($ARGV[0]); print $ip->address,$/;' eth0
