On FreeBSD 5.1, it appears, speaking both from the man page and from an actual test, that host does not use /etc/hosts at all. It would be nice to have a command which uses getaddrinfo() but host does not. ping would be a better test: ~ % ping localhost PING fetiche (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.253 ms The name 'fetiche' was found in /etc/hosts. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I'm not sure what I'm looking for here. The machine that runs the ssh client is a Win XP box named 'bigdaddy'. That resolves on the Win XP box: C:\Documents and Settings\tomlinson_dr>ping localhost Pinging bigdaddy [127.0.0.1] with 32 bytes of data: Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 Reply from 127.0.0.1: bytes=32 time<1ms TTL=128 The FBSD box running sshd also resolves: blacksheep# ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.519 ms So what do I need to do? As I understand it, their needs to be an entry for the client machine in /etc/hosts which I have.

AFAIK, I'm using sshd from the base system with defaults. How can I check? Also, I use courier-imap. With desktop machines physically attached to my LAN, I don't have the IMAP clients using SSL and I get no delay connecting. However I have a laptop that I bring home from work on occasion and it is configured to use SSL. When I use it with a wireless card on my home LAN, I seem to get similar delays when using it's IMAP client. Might the two be related? Thanks for your help!

Are you using privilege separation? If you are, the ssh daemon is not looking for hosts in /etc. It will be looking somewhere else for the /etc/hosts file. Are you using sshd from the base?

How to Setup Reverse DNS on LAN?
When connecting via ssh to my FBSD boxes, it takes over a minute before the connection is established. Searching the archives suggests that this is due to a failed reverse DNS lookup that must time out before connecting. Suggestions include adding the hosts to the local host file which I've done. However this does not seem to provide reverse DNS resolution which appears required. For example, I have a Win XP machine at 192.168.1.3 named 'bigdaddy' and a FBSD box at 192.168.1.2 named 'blacksheep'. blacksheep contains a line in /etc/hosts: 192.168.1.3 bigdaddy bigdaddy.mykitchentable.net Using the 'host' command, I see that 'bigdaddy' gets resolved: blacksheep> host bigdaddy bigdaddy.mykitchentable.net has address 192.168.1.3 But 192.168.1.3 does not: blacksheep> host 192.168.1.3 Host not found, try again. Short of setting up named, is there a way to solve my problem?
