I just recompiled the kernel from -rHEAD and started logging things while I connected to my dialup provider. Apparently lo0 does have the 127.0.0.1 address *and* the LOOPBACK flag but somehow fails. When (near the end of the following log) I back only this change out, the problems go away :/ The strange thing is that my named listening on lo0 DOES reply, as you can see from the tcpdump output, but the reply never reaches the ssh process that initiated the query. ===== keramida@gray[05:05]/home/keramida$ ssh -l charon -p 666 -v labs.gr OpenSSH_3.5p1 FreeBSD-20021029, SSH protocols 1.5/2.0, OpenSSL 0x0090607f debug1: Reading configuration data /home/keramida/.ssh/config debug1: Applying options for * debug1: Reading configuration data /etc/ssh/ssh_config debug1: Rhosts Authentication disabled, originating port will not be trusted. debug1: ssh_connect: needpriv 0 ^C root@gray[05:04]/root# tcpdump -i lo0 -s 128 -v -n tcpdump: listening on lo0 05:05:34.616515 127.0.0.1.49181 > 127.0.0.1.53: [udp sum ok] 24818+ AAAA? labs.gr.
