CVS and rsh questions

[Paddy T]

Hi

I have a question regarding how CVS works.
How is CVS dependent on rsh?On some client machines
here,cvs client-server works fine even though rsh is
not installed on that machine.(Unix server-NT/win 98
clients)It says in the manual that for :server
method,CVS uses rsh.So how does CVS work on those
machines?Can someone tell the difference between
internal and external rsh client?
And sometimes,some people get the error
"Cannot login as local user "xxx" and remote user
"xxx" ;permission denied by rshd"

What is rshd?
They get it suddenly;once a guy committed something
and at the next commit immediately afterwards,he got
this error.It went away just as suddenly after
rebooting the machine.What causes this error?I checked
the CVS/Root file/s;nothing copied from another work
space or like that.
I will be thankful to anyone who can clarify these
questions.

TIA,
Paddy Thomas
