Sounds like you may be having a gateway redirects problem. One symptom
is connections that have been working are randomly dropped and can't
reconnect. Run NETTOOL.NET.SYS as system manager and enter
NAMEADDR;ROUTING;GATELIST and you'll get a list of where your traffic
is going. You may see some IP addresses going to non-existant gateways.
These would be the IP addresses you say have been working before but
now don't work and your work-around has been to reassign new IP's to
the boxes. If you see this, exit NETTOOL and do a NETCONTROL
NET=LAN000;UPDATE=INTERNET (replacing LAN000 with your network name of
course). This should reset your gateway list and maybe solve your
problem for the moment.
The real problem in a situation the above solves is Cisco routers send
redirect directives that HP3000's pay attention to, without question
(and according to the standards). It's the Cisco equipment at fault.
They should be configured to not issued redirect command packets.
Hope this helps!

Well, I thought I had it licked. Since I changed hops to 3 (based on
seeing 3 routers in tracert), things seemed ok. Then came in Monday, 2
remote sites having trouble connecting...sort of. They can use email
and access web (through head office firewall), but as soon as they log
on to the hp (vt-mgr), they get welcome messages, main menu is fired up
by logon udc, end of conversation - no further data is seen, no
response, only exit is kill reflections. They should see the menu start
up dialogue asking for date, printer etc.
When this problem surfaced first, we changed MTU on the PCs down to
1400 on those that needed it. This time, we found some PCs hadn't had
their MTU changed, we did that and they worked. Other PCs that already
had their MTU changed, we only got working by changing their IP
address, which is the same thing we had to do to get spooled network
printers working again......
Is there a setting in VT-MGR or NMMGR that I need to look at? Is there
a way I can kill a spooler thread that has got hung up on a network
printer - took a long time for some printers to die and be able to
stopspool on them. We have had 250+ vt-mgr sessions before, and we
weren't up against that limit.
Help!!!!!!!

Make sure there are no firewalls (or routers with possible filter rules)
between you and the printer you're checking.
For some of our local printers:
:snmpget.net.sys 10.102.82.44 0 1.1.0
Name: system.sysDescr.0
Octet String: HP ETHERNET MULTI-ENVIRONMENT,ROM
K.07.15,JETDIRECT,JD38,EEPROM K.08.04
:snmpget.net.sys 10.102.144.83 0 1.1.0
Name: system.sysDescr.0
Octet String: HP ETHERNET MULTI-ENVIRONMENT,ROM
A.05.03,JETDIRECT,JD24,EEPROM A.05.05
This system is MPE/iX 6.5, though snmpget should work the same on older
OSes as well. You can try a :HELP SNMPGET.NET.SYS to ensure that the
parameters are the same on your system:
:help snmpget.net.sys
USER DEFINED COMMAND FILE: SNMPGET.NET.SYS
parm gateway, community, variable,
v2="",v3="",v4="",v5="",v6="",v7="",v8="",v9=
"",v10="",v11="",v12="",v13="",v14="",v15="",v16="",v17="",v18="",v19=""
,v20=""
option nobreak

Chris,
Thanks - here is what I get from snmpget--
:snmpget.net.sys 192.168.56.141 0 1.1.0
Error in request. Request status is 42. (SNMPWARN 909)
The snmp_parse function failed in varbind list.(SNMPERR 42)
I get the same result on a local subnet (192.168.2.200, 3000 is
192.168.2.2) printer also.
Does this tell us anything??
TIA,
jp

John,
Make sure SNMP traffic can get through to/from your printer.
From your 3000, you can test this by:
:snmpget.net.sys 192.1.1.2 0 1.1.0
(where 192.1.1.2 is the IP address of the printer in question)
You should get a general status/description return from the printer. If
not, check for firewalls or routers blocking SNMP traffic. The 3000
spooler uses SNMP to determine printer status, so blocking that traffic
will cause the spooler to lose track of the printer...

Subject: [HP3000-L] hp laserjets on adsl network (Private ip) spooled
from mpe-problems
We have just gone over to a private ip network via adsl links, from
being on a frame relay(bridged - mixture of nextworked and serial
printers). For a few weeks we were ok, but lately I am seeing printers
giving IPRECCV \messages, losing the spooler, and going unresponsive. I
can ping them, and reach them with web browser, but the spooler cant
see them , cant print anything. Stopping and starting spooler, abortio
until none left, nothing helps. Only thing that works is to change the
IP address....These are a mix of 1200, 2300, lj5, so its not model
specific. They are all default configs - syslog max=10,syslog
pri=7,idle timeout=270,ttl/slp=4, but WINS data or syslog server. My
network provider is saying talk to HP, not our problem....
anybody BTDT please? Getting hard to keep up with it - 3 different sites
in quick sucession this morning... DO I need more network, config
change? Console only shows the spooler error - connection terminated by
something. Where can I get more detailed info?
TIA,
jp
