Description Norman Back 2020-04-19 13:05:51 UTC 
With <host-name> <=sys-kernel/gentoo-sources-5.5.9 net-misc/netkit-rsh works correctly.
rsh <host-name> connects to <host-name>
With <host-name> >=sys-kernel/gentoo-sources-5.5.1- net-misc/netkit-rsh fails to connect.
rsh <host-name> does nothing with no errors reported.
 


Reproducible: Always

Steps to Reproduce:
1. boot a remote system with >=sys-kernel/gentoo-sources-5.5.10
2. rsh <host-name> where <host-name> is the remote system above.
3. rsh does not connect to the remote host but simply exits without error
Actual Results:  
rsh does not connect to the remote host but simply exits without error

Expected Results:  
rsh connects to <host-name>

Comment 3 Norman Back 2020-04-19 13:11:15 UTC 
I suspect other protocols, other than netkit-rsh, may also be affected.
Comment 4 Norman Back 2020-04-30 11:21:14 UTC 
Fixed in 5.6.8 by commit 82c9ae440857840c56e05d4fb1427ee032531346
