However, I do not have DNS running. I do not have localhost listed in /etc/resolv.conf. /etc/nsswitch.conf lists 'hosts: files dns' and putting my ssh origination id in /etc/hosts has no effect. It appears to be related to code in canohost.c. Before I start debugging, I thought I'd ask if anyone knew if there is a reason for this behaviour, or where it might be coming from (specifically).
