HP Procuve Manager - Discovery of endpoints 1

[JimInKS]

Just installed HP Procurve Manager software -

I am having trouble getting it to discover PC's on the network. It seems to have found my 3 procurve switches (what manager calls interconnect devices) and my printers (end nodes), but only 1 unknown device (the PC the procurve manager is intalled on).

I have made sure that the 'Ping Sweep' settings seem reasonable and I can see manager doing a 'Ping Sweep', but no other PC's or network devices are being discovered.

If I understand Manager correctly it should discover every IP address on the network with the dumb devices, like most PC nics, falling into the 'unknown device' category.

Any ideas anyone?

When you look at the regular Newtork Neigborhood, is all the computers showing up there? Also, is there any kind of security features on the work stations that might prevent the Switches from getting the information, and from installing it's management tool on the workstation?

 

[JimInKS]

Yes, all computers show up in network neigborhood. I can ping them from my PC that has the Procurve Manager software installed on it. I just have a small (about 70 PCs) plain vanilla network.

I don't want any management software installed on the PC's, I would just like to be able to see what IP addresses are on each port of my switches. The old Toptools software used to do this.

I found the same problem with the new HP Management software, I went back to the top tools. It was a lot easier to work with.

Hi ,

I wrote something in perl to do this based on the mac tables of 2524 switchs and mac table of my routers.
If you a interested in i can shared it , in fact, as i'm not programmer, i would be interested if someone can have a look and shared any improvements .

Bye.

I found that i could not get end nodes to come up either.
Then i thought, doesn't this work becuase of snmp?
Are all of your end nodes running smnp?
Try turning one on and see that helps.
Are all of your w/s HP?

My experience has been like PoliMalaka. I installed SNMP on my workstations and even the Windows 98 workstations were getting "discovered."

FWIW,

Well, one of the problems is that snmp opens up a host of security issues.
Will your administration/leadership allow for this?
If you are this, are you willing to take the risk?
Also, will the snmp machines show up on the network diagrams? I can't get them to show up there.

 

[JBruyet]

Yes, my administration/leadership is ok with this, but I think it's primarily because I told them I wanted to do it. As to the security issue, my network is only about 60 workstations in two sites. My regular users know who is and isn't supposed to be using the machines. I'm pretty anal about permissions too, which irritates some of my users. Thusly, yeah I'm willing to take the risk. And lastly, all of the workstations that have SNMP installed do show up in the maps. That really makes locating a computer easier as I can tell which site it's on.

My 2 cents worth,

I don't think snmp is a good idea here as we have a segment of our user population that is quite transient. Oten someone will come into the building with a laptop or PC (not approved for use with appropriate Antivirus software etc.) and will plug in and go and sometimes even kill us.
We have more than 500 active network connections to manage, so locking the ports to a single MAC would be cause more much trouble than it would be worth.
Locating the offending devices isn't too difficult though.
The more difficult task would be enabling snmp on all the network devices.
Any suggestions?

 

[JBruyet]

Sounds like a nightmare to me. If someone tried bringing in a laptop here everyone would be asking them if they had talked to me about it. I make it a point to let people know about what's going on with the network--spam filter stats, file sharing servers I find by doing network sniffs (Kazaa, Gnutella), viruses intercepted by my mail server, stuff like that. As I involve them and let them know what I'm doing and why they kind of help me police the network. If you're asking specifically if I have an idea on how you can install SNMP on all your computers, I don't know but my guess is you should be able to do it through a policy or a script. I don't know any further than that. Hope you get this figured out and running!

raztaboule - I'm very interested in your script!
