我想构建新版本的 Open Pegasus Client (2.14.1)。不幸的是,我正面临一些构建问题。有人知道这些问题的一些解决方法吗?
我的环境是:
我的场景很简单:
这些设置:
call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\vcvars32.bat"
set PEGASUS_ROOT=D:/Dev/pegasus-2.14.1/pegasus
set PEGASUS_HOME=%PEGASUS_ROOT%
set PEGASUS_PLATFORM=WIN32_IX86_MSVC
set path=%path%;%PEGASUS_HOME%\bin
set OPENSSL_HOME=D:/Dev/OpenSSL-Win32
set PEGASUS_HAS_SSL=true
buildmu"=> 成功构建并复制到 "/bin"文件夹。我会
喜欢构建 Pegasus 所以:“make build” => 一段时间后我得到了这个
错误:
Message.cpp(433):错误 C2065:'magic':未声明的标识符
在\pegasus-2.14.1\pegasus\src\Pegasus\Common\Linkable.h 文件中,所以我
有两个选项:a) 将构建配置切换到 DEBUG(设置
PEGASUS_DEBUG=true) b) 从第 62 行中删除 DEBUG 条件
Linkable.h 文件然后,不幸的是,我再次尝试构建 Pegasus
我收到此错误:
错误 LNK2005:_OPENSSL_Applink 已在 SSLContext.obj 中定义
在这一点上,我不知道如何解决这个问题。我只是试图删除这些行:
# ifdef PEGASUS_OS_TYPE_WINDOWS
# include<openssl/applink.c>
# endif
来自 SSLContextRep.h 文件。在此修改后,我能够获得 Pegasus 客户端二进制文件。但是这些二进制文件只在没有 SSL 的情况下工作,当我想使用 SSL 通信时,我总是遇到错误:“
Pegasus 异常:'无法连接到 10.199.1.139:5989。连接失败。'。”,所以我认为这是因为我在 SSLContextRep.h 中修改了代码。
Pegasus Tracer 的输出:
SSL:未连接 1 错误:140740BF:SSL 例程:SSL23_CLIENT_HELLO:无可用协议(protocol)
SSL:删除的 SSL 套接字
有谁知道有什么问题?有人拥有一些(更好的)Windows 环境配置步骤来构建 OpenPegasus 吗?
非常感谢您提供任何帮助。
编辑:
我需要能够在没有证书的情况下工作。因为我使用 SSL 与各种存储阵列通信,但我没有它们的证书。因此我使用 SSLContext 的这个构造函数:
SSLContext sslContext(String::EMPTY, NULL, String::EMPTY);
这种方法在 OpenPegasus 2.13 版本中对我很有效。
最佳答案
Outputs from Pegasus Tracer:
SSL: Not connected 1 error:140740BF:SSL routines:SSL23_CLIENT_HELLO:no protocols available SSL: Deleted SSL socket
这是消息的来源:
$ grep -nR "Deleted SSL socket" *
src/Pegasus/Common/TLS.cpp:172: PEG_TRACE_CSTRING(TRC_SSL, Tracer::LEVEL3, "---> SSL: Deleted SSL socket");
以及第 172 行附近的代码:
SSLSocket::~SSLSocket()
{
PEG_METHOD_ENTER(TRC_SSL, "SSLSocket::~SSLSocket()");
close();
delete static_cast<SharedPtr<X509_STORE, FreeX509STOREPtr>*>(_crlStore);
SSL_free(static_cast<SSL*>(_SSLConnection));
PEG_TRACE_CSTRING(TRC_SSL, Tracer::LEVEL3, "---> SSL: Deleted SSL socket");
PEG_METHOD_EXIT();
}
如果你查看
.../src/Pegasus/Common/SSLContext.cpp
,你会看到:SSL_CTX* SSLContextRep::_makeSSLContext()
{
PEG_METHOD_ENTER(TRC_SSL, "SSLContextRep::_makeSSLContext()");
//
// create SSL Context Area
//
SSL_CTX *sslContext = NULL;
if (!(sslContext = SSL_CTX_new(SSLv23_method())))
{
PEG_METHOD_EXIT();
MessageLoaderParms parms(
"Common.SSLContext.COULD_NOT_GET",
"Could not get SSL CTX");
throw SSLException(parms);
}
int options = SSL_OP_ALL;
SSL_CTX_set_options(sslContext, options);
if ( _sslCompatibility == false )
{
#ifdef TLS1_2_VERSION
// Enable only TLSv1.2 and disable all other protocol (SSL v2, SSL v3,

#else

"TLSv1.2 protocol support is not detected on this system. "
" To run in less secured mode, set sslBackwardCompatibility=true"

throw SSLException(parms);
#endif
}
// sslv2 is off permanently even if sslCompatibility is true
options |= SSL_OP_NO_SSLv2;
SSL_CTX_set_options(sslContext, options);
#ifdef PEGASUS_SSL_WEAKENCRYPTION
if (!(SSL_CTX_set_cipher_list(sslContext, SSL_TXT_EXP40)))
{
SSL_CTX_free(sslContext);
sslContext = NULL;
MessageLoaderParms parms(

"Could not set the cipher list");
throw SSLException(parms);
}
#endif
if (_cipherSuite.size() != 0)
{
if (!(SSL_CTX_set_cipher_list(sslContext, _cipherSuite.getCString())))
{
SSL_CTX_free(sslContext);
sslContext = NULL;

我会出于两个原因放弃该功能,并添加如下内容。
首先,它是编写为客户端和服务器的非晶例程之一。我从使用 OpenSSL 的经验中发现,您对
SSL_CTX* GetClientContext()
和 SSL_CTX* GetServerContext()
有单独的函数。其次,从安全工程的角度来看,您不允许人们因
PEGASUS_SSL_WEAKENCRYPTION
或空密码列表之类的东西而进入不良状态。你把枪拿走,这样他们就不能用脚开枪了。SSL_CTX* SSLContextRep::_makeSSLContext()
{
PEG_METHOD_ENTER(TRC_SSL, "SSLContextRep::_makeSSLContext()");
SSL_CTX *sslContext = NULL;
if (!(sslContext = SSL_CTX_new(SSLv23_method())))
{
PEG_METHOD_EXIT();
MessageLoaderParms parms(
"Common.SSLContext.COULD_NOT_GET",
"Could not get SSL CTX");
throw SSLException(parms);
}
// TLS 1.0 and above. No compression because it leaks information.
static const long options = SSL_OP_NO_SSLv2 | SSL_OP_NO_SSLv3 | SSL_OP_NO_COMPRESSION;
SSL_CTX_set_options(sslContext, options);
const char* const PREFERRED_CIPHERS = "HIGH:!aNULL:!kRSA:!PSK:!SRP:!MD5:!RC4";
int res = SSL_set_cipher_list(sslContext, PREFERRED_CIPHERS);
if(res != 1)

TLS 1.2 和 AEAD 密码套件是一个非常好的选择。但是,对于大多数意图和目的,TLS 1.0 及更高版本没问题。
我认为这可能是客户端中
0x140740BF
的原因。它来自 SSLContext.cpp
824 行:SSL_CTX_set_verify(sslContext,
SSL_VERIFY_PEER | SSL_VERIFY_CLIENT_ONCE, prepareForCallback);
看起来服务器需要证书。
...但通常您会收到不同的 TLS 警报。
并且来源没有调用
SSL_set_tlsext_host_name
,所以 SNI 似乎被破坏了。您可能应该为此提交一份错误报告...$ grep -nR SSL_set_tlsext_host_name *
$
您必须弄清楚客户端在哪里建立连接,并将其设置为
SSL*
选项:SSL_set_tlsext_host_name(ssl, hostname);
SSLSocket::SSLSocket
附近的某个地方可能是一个不错的选择,因为它的构造函数接受一个字符串,并且 sslConnection
在 ctor 中可用。SSLSocket::SSLSocket(
SocketHandle socket,
SSLContext * sslcontext,
ReadWriteSem * sslContextObjectLock,
const String& ipAddress)
但我很确定您需要的是 DNS 名称而不是 IP 地址,因为同一 IP 上不同服务器的多路复用首先导致需要 SNI。
但我可能是错的。
const String& ipAddress
实际上可以是一个 DNS 名称。关于c++ - 打开 Pegasus 2.14.1 客户端连接问题,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/30567717/
