How exactly does the software upload feature work in TCM? I've been trying to update some cards from behind a firewall, and have not had much luck. I've opened up incoming tftp (udp port 69), but I still get the "tftp timed out" error.
Is there a (semi) easy way to just do this with ucd-snmp, some perl, a tftp server, and the correct OID's? How are the cards indexed for software download?
It can be done. If I remember correctly, and its been a while since I've really looked into this. There are SNMP values that are set on a row in a table to tell the NMC to download the code using tftp. (Which you probably figured out so far) I don't remember the SNMP values off the top of my head, but I think I remember that it is documented in a lot of the software upgrade release notes from 3Com. Should be able to grab that and it'll tell you. The problem that I suspect that you're running into is that tftp will often "float" its port numbers....meaning that the initial contact is made to the tftp server on port 69, with the source port being a higher port number, then when the tftp server responds, it will use the port that the client sourced the connection from along with its own high port number...this means that the tftp "connection" (its udp, so its not a "true" connection in the tcp sense) no longer uses port 69 at all. This may be where your firewall is running into problems. :/ -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
