Can anyone tell me why when trying to use the Domain Manager in
ProbewatchV3.1 for Windows I get "Error accessing agent probe3!
While retrieving domains Error: Cannot open SNMP session with agent".
I can talk to the probe using Probewatch from an Ultrix platform ok.
I have launched the Data Capture ok and uploaded successfully.
Thanks,
Giles.

Gil, I have similar problem with my PC see 1759. I am using a DECPC 425 SL (486; 8 MBytes mem and PCMCIA XIRCOM adaptor card),a so called Workbench PC (OLIVETTI). I have spend already a day to fix that one without result , installing deinstalling the softwrare, changing IP stack, upgrading the XIRCOM driver and so one. What I see is that after several minutes, the PC can't communicate with the agent, I think also that this problem occurs when the load is high on the segment you want to monitor. From DOS you can ping on everything excepts the probe, but the probe is well reponding if you access it from another system, so the problem is in the PC and I should say in the IPStack or in the configuration ? If you wait a while then you are able to access the probe again. I did the same on DECPC 325 a DEC one (386; 8 Mbytes) same IP stack as in the kit, same XIRCOM adapter card, same config and it WORKS. Unfortunatly I don't have the time and other PC to play with, what I suggest you is to install it on another PC, that may perhaps help for the debugging of this problem. Best regards, Robert | |||||
| 1778.2 | This is a limitation of the PC. | SEOSS1::HARB_GE | George Harb, CNS, SEO6-15, 545-4202 | Thu Dec 15 1994 12:03 | 11 |
I've seen the same problem using the Frontier NETscount PC client
running on MS Windows (it's the same software as Probewatch). There is
a limitation with the IP stack with respect to the number of SNMP
sessions that can be active at any one time. You'll find that if you
close any other window that you launched with probewatch, you'll be
able to open a new one.
That's just the limitation of the PC. Best bet is to go to a UNIX
platform.

| 1778.3 | Make UDPMaxSock = 20 | NAC::FORREST | Wed Dec 28 1994 16:20 | 5 | |
I've noticed that this problem pretty much disappears if you edit
PWTCP.INI and increase UDPMaxSock to 20.
I think the problem is that the buffers allocated for UDP traffic
is too small for PROBEwatch.
