I use rsh in conjunction with CVS on my linux box to access a repository kept on a Solaris system. Or at least I *used to*. I've just upgraded to RedHat 7.1 and now rsh to those hosts doesn't work any longer. I just get errors like the following: prompt> rsh -d <hostname> uptime poll: protocol failure in circuit setup No matter what command I do, I get this error. Mystifyingly enough, at the same time, rlogin works just fine. The only thing I can think of is that RedHat 7.1 comes with a new version of rsh that is more fussy about some protocol than our Solaris systems are. I am still able to use CVS w/ rsh from Windows 2K (for shame!), so the problem seems to be Linux. Any of you had experiences like this? [I also find that smbfs works less well than it did on the 2.2.21 kernel I had built before the install....] R
