Hi List;
I have a machine I want to ssh to with no passwd. I've done this on my local
fedora 7 box:
$ ssh-keygen -t dsa -f .ssh/id_dsa
$ cd .ssh
$ scp id_dsa.pub user@remote:~/.ssh/id_dsa.pub
Then I connected to the remote box and did this:
$ ssh user@remote
[remote-box] $ cd .ssh
[remote-box] $ cat id_dsa.pub >> authorized_keys2
[remote-box] $ chmod 640 authorized_keys2
[remote-box] $ rm id_dsa.pub
[remote-box] $ exit
The scp took like 5min
Then I try and connect like this (remote box is 172.16.128.128) :
$ ssh -v 172.16.128.128
and I get this:
OpenSSH_4.5p1, OpenSSL 0.9.8b 04 May 2006

At this point ssh hangs for like 4 or 5 minutes, then I get this:
debug1: Server accepts key: pkalg ssh-dss blen 433
debug1: read PEM private key done: type DSA
debug1: Authentication succeeded (publickey).

Last login: Tue Sep 4 16:26:13 2007 from 172.16.128.1
Then it hangs again for another 2 - 3 minutes and finally I get a prompt.
the remote box is a windows XP box in vmware on my local fedora box running
cygwin
Usually really long timeouts that eventually work are caused by failing
DNS lookups as the remote side tries to reverse-resolve the connection's
IP address. From the target box, what does 'nslookup 172.16.128.1' (or
wherever your fedora box is) say and how long does it take? Another
possibility is that the remote side is trying an IDENT query on the
socket address to log the user name and a firewall drops (instead of
rejecting with an ICMP) the request making the query hang until it times
out.
