It's trying to do a DNS lookup on you when you login and failing to do so. Which are you logging into, eth0 or eth1?
192.168.56.1 is the address of the VBox adapter running on the host os (remember, the machine in question is a vm running under VirtualBox). That is the same address I specify as the gateway on the several OL 5.x vms I also have running on this system. From the host os:
HTML Code:
Ethernet adapter VirtualBox Host-Only Network:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::b4f9:a17a:f469:25a4%16
   IPv4 Address. . . . . . . . . . . : 192.168.56.1
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . :
The vm has two nics. The first is configured in VBox as NAT, is assigned to eth0, and is DHCP. The second is configured as host-only, is assgned to eth1 with a fixed ip address of 192.168.56.102. That is the address used to connect to it. My hosts file (on the host os, from where I am executing putty) has this entry:
Code:
192.168.56.102          vblnxsrv02.vbdomain vblnxsrv02

Found the solution. When configuring eth1 (mapped to the VBox hostonly adapter) I supplied the address of that adapter as the gateway address. Going back through some logs, I saw that when building an OL 5.x system, I was never prompted for or presented with a field for a gateway address when configuring the NICs. I never really gave that a thought when the 6.3 setup did so, so I just filled it in and went on my not so merry way. Rebuilt the machine and deliberately left the gateway field blank, and solved not only the immediate problem (the long delay on login) but also the question of "what is different between this 6.3 setup and my previous 5.6 setups".

Thanks to all for your inputs.
