It hung, and I hit Ctrl-C:

At this point, I think it crashes and reboots... it doesn't even respond to a ping.

Code:
OpenSSH_3.5p1, SSH protocols 1.5/2.0, OpenSSL 0x0090701f
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Rhosts Authentication disabled, originating port will not be trusted.
debug1: ssh_connect: needpriv 0
debug1: Connecting to beckman [192.168.1.148] port 22.
debug1: connect to address 192.168.1.148 port 22: No route to host
ssh: connect to host beckman port 22: No route to host


Your ssh connection appears to work but at three occasions in your debug output it seems like you simply don't get what the target node returns. The ping not returning to your node does not necessarily imply that your target node is dead/rebooting (check with who -b). There may be a problem with the routing. Do both nodes have a route defined to the other node? Can you connect to the originating node from node "beckman"?

ssh-argv0

SSH-ARGV0(1)						    BSD General Commands Manual 					      SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.	If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).
