hi everybody, i found the problem with the 3des encryption i have comparen the snmpsend source code with the snmpsharpnet source code and the problem is in the EncryptPDU encryptionKey = ExtendShortKey(encryptionKey, secret, engineId, authProtocol);
and this step is missing i think in snmpsend and thats why the calculated key is wrong i will try to imnplement this extra function if someone wants to try, i can offen an open port to a working 3des agent, all the free available 3des agents are also not correct implemented thanks k1 ------------------------------------------------------------------------------ _______________________________________________ synalist-public mailing list synalist-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/synalist-public
