From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.7.5) Gecko/20041217 Description of problem: Option to use old kerberos version (-PO) is not working. Option for new kerberos version (-PN) works fine. man rcp: -PN -PO Explicitly request new or old version of the Kerberos ��rcmd�� protocol. The new protocol avoids many security problems found in the old one, but is not interoperable with older servers. (An "input/output error" and a closed connection is the most likely result of attempting this combination.) If neither option is specified, some simple heuristics are used to guess which to try. Version-Release number of selected component (if applicable): rsh-0.17-24.1 How reproducible: Always Steps to Reproduce: 1. rcp -PO -r <remote_host>:/<remote_fs> /tmp Actual Results: rcp: invalid option -- P Expected Results: remote copy from remote host to local fs. Additional info: I use -P0 (zero) and -PO (O) to proof if my syntax is wrong. But both options did not work.
Sure, the man page is for kerberosized "rsh" version but you run classic "rsh" without kerberos support. /usr/bin/rsh /usr/kerberos/bin/rsh $ /usr/kerberos/bin/rsh usage: rsh host [ -PN / -PO ] [ -l login ] [ -n ] [ -x ] [ -f / -F] command OR rsh [ -PN / -PO ] [ -l login ] [-n ] [ -x ] [ -f / -F ] host command $ /usr/bin/rsh usage: rsh [-nd] [-l login] host [command] You need to install krb5-workstation rpm package.
