If I change the type of the object to INTEGER, it works. So, I have proved that
mib2c does not like IpAddress. But, I have to use IP address for this object
type, because it is an Ip address. Please help!

Re: Crosscompiling Netsnmp-5.6.rc1 for arm-unknown-linux under Cgywin
Hi, Following up with my previous email, I've changed my script to ./configure \ --host=i686-pc-cygwin --target=arm-linux --with-cc=arm-unknown-linux-gnu-gcc \ --with-cflags="-s -static -O2 -Dlinux -mcpu=arm9" --with-endianness=little \ --enable-mini-agent --disable-applications --disable-scripts \ --disable-manuals --with-default-snmp-version="1" \ --with-mib-modules="llc_snmpagent" \ --disable-mibs \ --enable-static --disable-shared \ --disable-debugging \ --with-sys-contact=hayashi_...@yahoo.com --with-sys-location="art" \ --with-logfile="/var/log/snmpd.log" --with-persistent-directory="/var/net-snmp" echo echo "Make ..." echo make && echo "Cross-compilation Completed!!!" || exit $? echo echo "Make Install..." echo make install && echo "Installation Completed!!!" || exit $? and I noticed 2 things: 1. I need to delete /usr/local/sbin/snmpd.exe previously compiled for Cygwin, so the binary snmpd can be created for my target board. 2. I cannot run `snmpd` on my host, but it runs with the following error on my target `error while loading shared libraries: libpthread.so.0: cannot open share object file: No such file or directory`. Notice that I tried to compile the agent statically, but still asking for share libraries. Should I modify the agent Makefile? Thanks!

I was also be able to extend the agent with my own mib (LLC-MIB.txt), with source file `llc_snmpagent.c` and `llc_snmpagent.h`. Everthing works fine on my PC, snmpget, snmpset, and trap generation. Now, I am trying to cross-compile it for a embedded board with a ARM9 core runing Linux 2.4. I already tested the cross-tool-chain from the board provider with some simple programs. And it works fine. I use the following script to crosscompile netsnmp under Cgywin for my target board (ARM9): echo "Cleaning Make ..." echo make clean echo echo "Cleaning Configure ..." echo make distclean echo echo "Configuring ..." echo ./configure \ --host=arm-unknown-linux --target=arm-unknown-linux --with-cc=arm-unknown-linux-gnu-gcc \ --with-cflags="-g -O2 -Dlinux -mcpu=arm9" --with-endianness=little \ --enable-mini-agent --disable-applications --disable-scripts \ --disable-manuals --with-default-snmp-version="1" \ --with-mib-modules="llc_snmpagent" \ --with-sys-contact="leo@commscope.com" --with-sys-location="art" \ --with-logfile="/var/log/snmpd.log" --with-persistent-directory="/var/net-snmp" echo echo "Make ..." echo make && echo "Cross-compilation Completed!!!" || exit $? make install && echo "Installation Completed!!!" || exit $? The script runs fine without errors, however, when I checked the agent `snmpd`, it is compiled to run under Cgywin, not ARM9. I found out by runing the `snmpd` on Cgywin and it works, plus the file as .exe suffix `snmpd.exe`.

question about OCTET STRING encoding within an index
While testing and reviewing my SNMP test harness I've come across an instance of a variable with an index I can't explain (on my Fedora box). snmpwalk -v1 -cpublic -On localhost vacmContextName .1.3.6.1.6.3.16.1.1.1.1.0 = STRING: So the index on this column is '.0' (which is defined as an OCTET STRING). What I'm confused about is... is the zero: a) the length of the non-existent NULL string that follows? or b) is it a string that contains a NULL? Normally I would have expected something like: 3.65.66.67 to represent the string 'ABC' where '3' is the length (aka number of sub-identifiers) variable length fields types as the 'n-1' parts of an index MUST be length encoded, but ISTR that if its the last variable in an index list, that the length always is omitted? As in: snmpwalk -v1 -cpublic -On localhost snmpNotifyRowStatus .1.3.6.1.6.3.13.1.1.1.5.105.110.116.101.114.110.97.108.48 = INTEGER: active(1) where the index (a 'name' associated with the row) is 105.110.116.101.114.110.97.108.48 ie. 'internal0' where there was no length specified. Does this mean that an empty OCTET STRING (or OBJECT IDENTIFIER) as the last INDEX component is a special case?

RE: how can I decode a PDU?
What if you make a small program that gets the PDU from the serial and relays it to net-snmp using a socket to 127.0.0.1 UDP port 161 and relay back the answer to the serial, sort of a bridge between serial and socket. No need to decode the PDU. In this way net-snmp would do the work for you and you'd only have to develop a subagent to handle the objects involved. Subagent that will also work if accessed through LAN.

Re: How to add rocommunity public without using conf-files
Thank you Wes, I'll try it.
I know that it is no good style, but we don't want to make it configurable.
Hopefully, the writing of the usr\bin file is disabled, because it looks
pretty strange on a windows system.
However, Thank you Wes.

Re: SNMPv3 inform request overrides USM parameters of the configured user
Thanks for the pointer Wes, but I dont think I am confusing between the two (Traps and Informs) since I am using the engine Id of the receiver while creating the user in USM for the Informs. I also debugged this further and found that there is a function 'create_user_from_session' which gets invoked while sending the INFORM message. In this function the user is fetched from the current user list; even if the user exists with the correct engine id (that of the receiver) and security name, the USM parameters (protocols and keys) of the user are being overwritten with some session USM parameters (the default session priv protocol is DES). I am not sure why this is being done; I have written to the coders mailing list and awaiting a reply for the same. -Datta.

As far as I can tell, the protocol specifies the maximum number of subidentifiers within a single OID, but not the number of varbind that are allowed in a single request. A very quick look at the code seems to indicate that this constant is simply there to simplify the handling of the command-line arguments. I don't believe it's dependent on anything in the SNMP protocol itself.
