Hello Folks,
Re: PING by NAME on 3000
Yep, Lars hit the nail on the head (or the head of the nail?)...
----------
The nslookup I use is "/BIND/PUB/bin/nslookup" which "only" performs the
"arpa" name lookup.
The ":netcontrol status" command returns the "ns" node name of a
system as configured in NMMGR.
:netcontrol status
...
NODE NAME : ECTOR.ATL.HPCOM
If I use the 'ns" node name with the nslookup it will fail:
:nslookup ECTOR.ATL.HPCOM
*** l3107ns1.ssr.hp.com can't find ECTOR.ATL.HPCOM: Non-existent host/domain
----------
The ":netcontrol status;net=lan1" command returns the IP address of
a system as configured in NMMGR.
:netcontrol status;net=lan1
...
NETWORK IP ADDRESS : $0F2C3034 15.44.48.52
If I use the IP address with the nslookup, it will return the "arpa"
name for the system (assuming a working/configured Domain Name Server).
:nslookup 15.44.48.52
Name: ector.atl.hp.com
Address: 15.44.48.52
----------
The ping in NET.SYS does not offer a ping by name, only IP (Sorry).
----------
The ping in NETTOOL supports lookup by both "ns" name and "arpa" name:
:nettool.net.sys;info="ping;ping ector.atl.hpcom;quit"
...
Pinging ECTOR.ATL.HPCOM
64 bytes from 15.44.48.52 : icmp_seq= 1 time= 4 ms
...
64 bytes from 15.44.48.52 : icmp_seq= 5 time= 2 ms
------------- FINAL STATISTICS -------------
5 packets transmitted, 5 packets received,0 % packet loss
round-trip (ms) min/avg/max = 2/2/4
:nettool.net.sys;info="ping;ping ector.atl.hp.com;quit"
...
Pinging ECTOR.ATL.HP.COM
64 bytes from 15.44.48.52 : icmp_seq= 1 time= 5 ms
...
64 bytes from 15.44.48.52 : icmp_seq= 5 time= 2 ms
------------- FINAL STATISTICS -------------
5 packets transmitted, 5 packets received,0 % packet loss
round-trip (ms) min/avg/max = 2/2/5
----------
Also, some one on the 3000-l list asked about a reverse lookup...
Yes, the "/BIND/PUB/bin/nslookup" will return an IP address if the
input is the "arpa" node name and will return the "arpa" node name
if the input is the IP address:
:nslookup 15.44.48.52
Name: ector.atl.hp.com
Address: 15.44.48.52
:nslookup ector.atl.hp.com
Name: ector.atl.hp.com
Address: 15.44.48.52
Note: On my machine I have done a newlink command for nslookup.
I hope this helps!
