Hi all, I'm trying to rsh in to a bunch of machines and use perl to do a search and replace of some text. It doesn't give any error message(s), but it also doesn't change the file on either the local box or the machine I'm rshing to.

This runs and *seems* successful by using normal rsh, but actually changes nothing. Note that it failed using the first two authentication methods, but is OK the last time. This is consistent with other commands with rsh that work. 

#/usr/kerberos/bin/rsh remote-host /usr/bin/perl -p -i -e
's/^#\s+NETDUMPADDR=/#\+NETDUMPADDR=\nNETDUMPADDR=ip-address-here\n/g'
+ /etc/sysconfig/netdump
connect to address ip-address-here: Connection refused
Trying krb4 rsh...
connect to address ip-address-here: Connection refused
trying normal rsh (/usr/bin/rsh)

even though this works, i.e. actually replaces text, on the local system:

#/usr/bin/perl -p -i -e 's/^# NETDUMPADDR=/# NETDUMPADDR=\nNETDUMPADDR
+=ip-address-here\n/g' netdump

I suppose I could rcp from the remote host to the local host, change it, then copy it back, but that seems kinda kludgey. Anybody know what I'm missing here?
