Well, not so sure here. I checked with tcpdump or strace, and snmpd sends this: 0\201\220\2\1\1\4\6public\240\201\202\2\4\0327\373\313\2\1\0\2\1\0000t0\16\6\n+\6\1\4\1\202\211w\n\t\5\0000\16\6\n+\6\1\4\1\202\211w\n\6\5\0000\16\6\n+\6\1\4\1\202\211w\n\2\5\0000\20\6\f+\6\1\4\1\202\211w\n\r\1\3\5\0000\20\6\f+\6\1\4\1\202\211w\n\r\1\2\5\0000\16\6\n+\6\1\4\1\202\211w\n\6\5\0000\16\6\n+\6\1\4\1\202\211w\n\1\5\0 and gets exactly that: 0+\2\1\1\4\6public\242\36\2\4\0327\373\313\2\1\0\2\1\0000\0200\16\6\n+\6\1\4\1\202\211w\n\t\201\0 After which it crashes. Probably gets something inappropriate... but still, it shouldn't just crash IMO. >> There was a similar case back in 2005, with no fix though: >> >> http://groups.google.com/group/mailing.unix.net-snmp-users/browse_thread/thread/2454a5a796fb5814/1e7ebe0455051c7a > > From a quick scan of that thread, it looks as if the underlying problem > was a bug in squid, which failed to handle GETNEXT requests for two or > more varbinds correctly. > Are you also working with squid - or do you have different proxied > applications? It's a different proxy application. -- Tomasz Chmielewski http://wpkg.org ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
