SSH 1.2.26 on Solaris 2.6

[Kins Orekhov]

Hi all!

Have some strange problem on Solaris 2.6 machine (sparc).
I'm trying to do following:

machine1$ tar cvf user@machine2:/tmp/filename.tar /etc \
--rsh-command=/usr/local/bin/ssh

And I got a message: 
tar: Cannot open user@machine1:test.tar: No such file or directory
tar: Error is not recoverable: exiting now

There's the same message even if I try to create filename.tar on machine1!
But that command works just fine on Linux boxes (RH6 and Debian2 on x86)!

Any suggestions?

TIA

Kins.
