Telnet in latest Cygwin

Telnet in latest Cygwin

[Andy Davidson]

Hi,

I have the latest Cygwin, setup is v2.819 (64 bit).  I want to install telnet but the inetutils package isn't in the installer any more.  It doesn't seem to be in the last version I installed around a month ago.  Any clues ?

Andy

The package still exists and 'telnet' is in there.  Try a different
mirror if the one you're using isn't showing the package.

Andy was asking about 64 bit.  Inetutils hasn't been ported to 64 bit
Cygwin yet, that's why it's missing.  I'd suggest to use ssh instead.
Telnet is inherently unsecure and ssh is a wonderful replacement.

Unfortunately, it doesn't work where you explicitly need to use telnet.
F.e. to connect to PON terminals.

Though, I fail to see, how Cygwin telnet is different from, say PuTTY. Or
native Windows telnet.

Windows 8 doesn't come with telnet.exe installed by default, and when 
you install it from Programs and Features, it's invisible to Cygwin 32, 
apparently due to the SxS madness.

Cygwin 64 *does* see it, but attempting to run it just drops you right 
back at a prompt, immediately.

Even if it did run, wouldn't things like Ctrl-] break due to the 
problems Cygwin currently has running interactive native console programs?

Windows' telnet.exe doesn't even run particularly well within cmd.exe. 
Telnetting to a local web server here, it didn't do local echo properly, 
so I couldn't see whether I'd typed "GET / HTTP1.0" correctly.  (I had 
Cygwin telnet.exe renamed to cygtelnet.exe during this time, to ensure I 
wasn't picking it up by accident.)

Have you tried sysnative in case installing telnet gives you a 32-bit
version as well as a 64-bit one?

Different versions of Windows have come with one of two telnets.
Early and late versions came
with the white-on-black, no-local-echo you have.  The others came with
black-on-white,
with-local-echo, window-closes-when-connection-closes.  IIRC, the one
that closed when the
connection closed was dropped from Windows prior to HTTP persistent
connections being widely
supported, so was never useful for diagnosing HTTP.

Basically, Windows telnet (both versions) is proof that MIC.  Microsoft Is Crap.

but telnet is an invaluable tool for command line troubleshooting tcp
network connectivity issues to SMTP, HTTP and other services by manually
typing the protocol commands into the server.  ssh can't do that

There's also netcat (nc).

http://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fnc%2Fnc-1.107-4&grep=%2Fnc.exe

Re: Telnet in latest Cygwin

[zeev]

You can use the 'nc' (aka netcat) instead of telnet

nc localhost 80

From a cygwin terminal it will give an equivalent result to 'telnet
localhost 80', and far better than Microsoft's #$&%#*%&$# telnet

Search for 'nc' in the cygwin installation.

good luck

Thanks for helping but you're responding to a message from October.
Please don't resurrect old discussions.
