Original Question:
I have a small problem and wonder if someone can help.
I am running a server with 4.0d and am using it at my nameserver for a
couple of lantronix servers etc that have been set up.
I had a lantronix server go bad. It has a bad port on it so I received a
new one. I set the lantronix server up exactly like the old one and then
put the new one in place. I changed the IP Address of the new one to
exactly match the old one. Everything looks to be the same.
The old one would connect to my unix server directly and then when
logged out all the user would have to do is type telnet alfred and it
would be there.
Does Unix have a limit on hardware addresses etc who can access the name
service or how does nameservice work?? I did use the original ip address
and also tried the ip address of our backup lantronix server. Nothing
seems to work. Everything seems to work except telneting by name.

We use lantronix for print servers, not the telnet capability ... but
here's
a couple o' things to check.
Not being sure what you did to init the new unit ...
(e.g. did you both "set" and "define" the addr info?) Regardless ...
With lantronix reset to factory default settings, from another host you
can:
arp -a | grep "lan.tronix.ip.addr"
if [ "there's an existing arp entry for the address" ]; then
arp -d "corresponding hostname"
fi
arp -s "lan.tronix.ip.addr" "lan:tron:ix:mac:addr"
ping "lan.tronix.ip.addr"
# ... the point of this exercise is that it will force the
# ... lantronix unit to pick up and retain the address.
telnet lan.tronix.ip.addr
# ... you can now "set/define" to your heart's content.
Remember that you need to BOTH set and define values to have them
persist
across a reboot of the lantronix.

Ok, It seems like there is a table of hosts and ip addresses in the
lantronix servers. you might need to create this table on the new
lantronx
server.
What I actually did:
Step one: (from another Unix host)
/usr/sbin/arp servername
/usr/sbin/arp -d servername
Step two : from the lantronix server
set/define host hostname host_ip example(set host
serv05 xxx.xxx.xxx.21)
init server delay 0
Now it works just like the old one.
