Follow-up Comment #4, bug #18969 (project lwip):
Made quite a bit more progress...
udp_bind() is ok... it turns out that it really was hanging at the call to
snmp_cold_trap(). I commented that out (work on that another day) and
started working on the snmp get stuff.
sending get to my lwIP SNMP embedded system:
receives udp packet... good
starts doing various tests .... good
completes recognition of iso.org.dod.internet ... good
when processing snmp_search_tree() always returns NULL
Good thing - it no longer crashes
Bad thing - I haven't figured out why it won't do the search tree. I'm
trying to send get iso.org.dod.internet.mgmt.mib-2.system.3, and .4 (which it
looks like the code should respond to). The ident length that is passed to
snmp_search_tree is 4 (which I expect). The ident value is 02 00 00 00 (I
have a routine to print as bytes)... I'm guessing each time through the while
loop will drill down to the next level so that isn't too odd (I double checked
that I was sending the right info with a packet sniffer). It takes the
MIB_NODE_SC branch and then returns NULL...
Any new words of wisdom on what to look @ next?
Thx,
TimS
