Add bracket match of CS (clearsilver) file in VIM
1. download matchit.zip for vim (script 39) and install it following the instruction
2. disable the vim default cs (c sharp) filetype plugin by doing:
cd /usr/share/vim/vim63/ftplugin/
sudo mv cs.vim csharp.vim
3. create out own cs filetype flugin
mkdir ~/.vim/ftplugin
vi cs.vim, and enter the following line:
:let b:match_words='<:>,<\@<=[ou]l\>[^>]*\%(>\|$\):<\@<=li\>:<\@<=/[ou]l>,<\@<=dl\>[^>]*\%(>\|$\):<\@<=d[td ]\>:<\@<=/dl>,<\@<=\([^/][^ \t>]*\)[^>]*\%(>\|$\):<\@<=/\1>'
4. done! now press % match < > and things like

net-snmp proxy
For Net-snmp proxy to work, you have to specify the following in your net-snmp snmpd config file:
----------------------
com2sec -Cn default
group v1
access any noauth exact all none none
proxy -Cn -v 1 -c .1.3
----------------------
for example:
--------
com2sec -Cn mycontext secname_public default public
group group_public v1 secname_public
group group_public v2c secname_public
view all included .1
access group_public mycontext any noauth exact all none none
proxy -Cn mycontext -v 1 -c public localhost:1161 .1.3
-----------
This will work.
Simply specify "rocommunity" and then add the proxy line does not work!!

build net-snmp on Windows
This is how to build net-snmp (version 5.4.2) on windows :
0. install MS visual Studio Express 2008 VC++
0.1 build openssl, copy headers and libs to visual studio include and lib directories according to net-snmp readme.WIN32
1. read file readme.WIN32 section "Manual build using Configure / nmake"
2. cd win32
3. change file build.pl line 34
#if (! (-d $ENV{MSVCDir})) {
to
if (! (-d $ENV{VCINSTALLDIR})) {
4. perl Configure --with-sdk --with-ssl --config=debug --prefix="c:/usr"
5. add the following code to the beginning of win32\net-snmp\net-snmp-config.h
#include
#include
#ifdef WIN32
#include "windows.h"
#include "winsock.h"
#include "iprtrmib.h"
#include "tlhelp32.h"
#include "iphlpapi.h"
#endif
also
change NETSNMP_DEFAULT_MIBS to:
#define NETSNMP_DEFAULT_MIBS "IF-MIB"
6. in file c:\tools\net-snmp-5.4.2\win32\netsnmpmibssdk\Makefile
comment out the 2 lines containing "winExtDLL.obj"
7. in file C:\Program Files\Microsoft Visual Studio 9.0\VC\INCLUDE\openssl/ossl_typ.h
comment out these two lines:
//typedef struct ocsp_response_st OCSP_RESPONSE;
//typedef struct ocsp_responder_id_st OCSP_RESPID;
8. in file snmplib\snmpTcpDomain.c, remove 2 includes files, and add socketlen_t define
#if HAVE_WINSOCK_H
#define socklen_t int
//#include
//#include
#endif
9. repeat last step for file snmplib\snmpUdpDomain.c, apps\snmpnetstat\inet.c, apps\snmpnetstat\inet6.c
10. nmake (you will see warnings about /YX, GX and unsafe use of strcpy, etc. they are safe to ignore for now.
I wish it is easier than this. Maybe next year. :-)

Yes, I confirm that the winpcap driver follows that model.

This is a good idea, but I'd leave it for the next winpcap release. We are sort of freezing the development to focus on fixing the last bugs in 3.1, so I'd prefer not to change the interface with libpcap now. The same applies to the "user buffer not emptied after a setfilter" problem.
