I started using a MacBook, and would like to know any recommendations for a terminal emulation program. I currently use SecureCRT when I am at work. If you have any recommendations I would like to hear them as I sure the community would as well.

Thanks Nick

I use Telconi for Cisco, it works for Cisco only.

For MAC there is ZOC, which is very likely secure CRT alternative, however, I tried it and found that it is useless sometimes, it gives you troubles more than solutions, it is very buggy and unstable.

If you're using a Keyspan USB/Serial Adapter (which you should), you don't need an emulation program, use Screen.

screen /dev/tty.KeySerial1

Type that in a terminal window after you've connected the adapter and you're all set. If you want any further info on Screen you can man it.

Digital,

Thanks for the information. Where can I get more information about screen. What does "man it" mean.

Thanks Nick

Well, terminal emulation is more general than just connecting via the console interface of the device, it includes telnet/ssh as well.

Well, you can use screen to connect via console, but there is no features, no tracking, no export features ... etc

I believe ZOC is very likely an alternative to SecureCRT, however it is a little bit buggy. You can use Telconi for telnet/ssh with a lot of automation features.

PS: man the applications means to issue the command man screen in a terminal window, that will give you the help pages or manual pages.

Thanks

I switched over to a Mac a little over a year ago. I use ZTerm with a KeySpan adapter. Works great for console connections.

"no features" when you use screen? what are you smoking?

screen provides scrollback, copy and paste, activity monitoring, logging and a pile of other features, all available from the keyboard (no need to get RSI reaching for the mouse!).

eg. wanna save a copy of the config of an IOS device when you're stuck on a serial console?

  • show run (and page through it)
  • hit ctrl-a then [ (you're now browsing the terminal's history buffer)
  • move up to the last line of the config, and hit return (you're now marking a section to copy).
  • now hit ? to search, and enter, say, "^hostname" (without the quotes), which'll get you near the top.
  • move up a few lines and hit return
  • now you have a copy of the config in screen's paste buffer, which you can write out to a file with ctrl-a then >
  • it'll write it somewhere like /tmp/screen-exchange by default: you can rename this into the location you want.

Don't be scared of the command line on a Mac! It's extremely powerful. screen is an indispensable tool for using the unix command line effectively. There's no need for expensive software like ZOC and such ($80 for a terminal emulator?!), since you can telnet or ssh directly from a shell in the Mac's Terminal app.

If you google "screen tutorial", the first link (at kuro5hin.org) is worth a read.

Have fun!
