Hi !
Is rcp broken somehow ?
I want to write a new IOS image to my routers flash.
I want to try rcp instead of tftp.
Here a session trace with debug ip tcp rcmd enabled.
Proceed? [confirm] =
Address or name of remote host [172.16.2.1]? =
Source username [ios]? =
Source filename [c2500-ios56i-l.121-5.T.bin]? =
Destination filename [c2500-ios56i-l.121-5.T.bin]? =
The returned username is ios(36008C) =
Accessing rcp://ios@172.16.2.1/c2500-ios56i-l=
.121-5.T.bin... %Error opening rcp://ios@172.16.2.1/c250=

Router config looks o.k.:
ip rcmd rcp-enable
ip rcmd rsh-enable
ip rcmd remote-host andreas 172.16.2.1 andreas enable
ip rcmd remote-host cisco 172.16.2.1 cisco enable
ip rcmd remote-host cron 172.16.2.1 cron enable
ip rcmd remote-username andreas
ip rcmd source-interface Ethernet0
/home/andreas/.rhosts has proper permissions:
-rw------- 1 andreas andreas 174 1 Dez 07:56 /home/andreas/.rhosts
c2516
172.16.2.2 (is the routers IP).
I played around with two settings in /etc/pam.conf
# r-utils are broken; ensure this doesn't bother folk
#rshd auth required pam_deny.so
rshd auth required pam_permit.so
My /etc/inetd.conf looks like this:
shell stream tcp nowait root /usr/libexec/rshd rshd
added this to /etc/inetd.conf as a test, kill -1 <PID of inetd>
exec stream tcp nowait root /usr/libexec/rexecd rexecd
Did I overlook something ???

The other way around works fine ...
