sslbio.cpp哪里去了？？

makefile里少编译了一个文件，参考openwrtbuildv2.sh就知道少了openssldl.o，makefile改成
CC?=gcc
CXX?=g++
CFLAGS+=-fexceptions -DOPENSSL=1 -O2
CXXFLAGS=-fexceptions -DOPENSSL=1 -O2
LIBS=sendmsg.o openssldl.o cJSON.o nonblocking.o sslbio.o ngrok.o main.o

clean:
rm -f $(LIBS) ngrokc
编译通过，请大神修正一下

我编译的原版ngrok服务端，它是证书编译的，没有toke功能，所以ngrokc连不上。
请问有办法解决证书认证问题吗？或者有没有带toke功能的服务端，我想自己架设服务器。
感谢您

按照openwrt傻瓜式教程，可以成功编译出ngrok，但是放到/usr/bin中启动时提示：BusError

first，非常棒的项目！小巧精悍，各个平台都可以使用，Thanks for sharing ~~

貌似ngrok-c 不支持openssl 1.1版本，而且在openssl 1.1的环境下运行也会报错

ngrokc v1.48-(2019/01/23)
OpenSSL init fail.
Please check if the OpenSSL is installed.
OPENSSL_add_all_algorithms not found.

由于 OpenSSL 1.0 到 1.1 API有很大的变化，导致很多APP不兼容，可能ngrokc也不支持？

于是验证了一下（以下测试在 x64 系统下进行）：

ngrokc 运行时，调用ssl库时是优先寻找 libssl.so 和 libcrypto.so, 然后才是 1.0版本的so

## file openssldl.cpp
 ssl_handle1 = dlopen("libssl.so", RTLD_LAZY);  
    if (ssl_handle1 == 0)
        ssl_handle1 = dlopen("libssl.so.1.0.0", RTLD_LAZY);
    if (ssl_handle1 == 0)
        return "Erro ao carregar libssl.so";
    ssl_handle2 = dlopen("libcrypto.so", RTLD_LAZY);
    if (ssl_handle2 == 0)
    ssl_handle2 = dlopen("libcrypto.so.1.0.0", RTLD_LAZY);
    if (ssl_handle2 == 0)
    {
        dlclose(ssl_handle1);
        ssl_handle1 = 0;
        return "Erro ao carregar libcrypto.so";
    }

而我当前系统同时存在 openssl 1.0和1.1（1.1是后来安装的）

libssl.so 及 libcrypto.so 均是指向最新的1.1版本

# ls -l /usr/lib/libssl.so*
lrwxrwxrwx 1 root root     13  6月 22 10:06 /usr/lib/libssl.so -> libssl.so.1.1
lrwxrwxrwx 1 root root     24  1月 17 2018 /usr/lib/libssl.so.10 -> /usr/lib/libssl.so.1.0.0
-r-xr-xr-x 1 root root 514670  3月 15 2018 /usr/lib/libssl.so.1.0.0
-rwxr-xr-x 1 root root 688857  3月  1 10:37 /usr/lib/libssl.so.1.1

ls -l /usr/lib/libcrypto.so*
lrwxrwxrwx 1 root root      16  6月 22 10:05 /usr/lib/libcrypto.so -> libcrypto.so.1.1
lrwxrwxrwx 1 root root      27  1月 17 2018 /usr/lib/libcrypto.so.10 -> /usr/lib/libcrypto.so.1.0.0
-r-xr-xr-x 1 root root 2668513  3月 15 2018 /usr/lib/libcrypto.so.1.0.0
-rwxr-xr-x 1 root root 3367180  3月  1 10:37 /usr/lib/libcrypto.so.1.1

于是我改动了 openssldl.cpp，让它优先使用 1.0版本的库

## file openssldl.cpp
 ssl_handle1 = dlopen("libssl.so.1.0.0", RTLD_LAZY);         # 这里有改动
    if (ssl_handle1 == 0)
        ssl_handle1 = dlopen("libssl.so.1.0.0", RTLD_LAZY);
    if (ssl_handle1 == 0)
        return "Erro ao carregar libssl.so";
    ssl_handle2 = dlopen("libcrypto.so.1.0.0", RTLD_LAZY);        #  这里有改动
    if (ssl_handle2 == 0)
    ssl_handle2 = dlopen("libcrypto.so.1.0.0", RTLD_LAZY);
    if (ssl_handle2 == 0)
    {
        dlclose(ssl_handle1);
        ssl_handle1 = 0;
        return "Erro ao carregar libcrypto.so";
    }

重新编译，运行正常

ngrokc v1.48-(2019/01/23)
{"Type":"AuthResp","Payload":{"Version":"2","MmVersion":"1.7","ClientId":"7fbd328269da12e9def746d781503778","Error":""}}
{"Type":"ReqProxy","Payload":{}}

libstdc++.so.6' library contains
unsupported TLS bcm96480 mips 32
这个库是直接从编译器中复制出来的，编译无错误，运行就报此错误，无解求助

文章中的脚本应该不适合x86吧？我尝试了好几次都出错

之前一直用openwrt 15.05 CC 的SDK来编译ngrokc，一直是成功的，但是1.33/1.34/1.35，每次编译都出现：

看到很多类似如下的日志，可以设置不写入syslog吗？

没有http验证路由器直接暴露在外网太危险了 原生的客户端是有http验证这个功能的 请问如何实现 给个思路就成

RT

当Sdname含有"."时断线重连后会有问题！
测试发现如果Sdname:abc.bcd
第一次运行一切正常，
访问路由器网址为abc.bcd.XXXX.com
当路由器断线后ngrokc重连后会只会返回abc不是返回的abc.bcd
此时访问路由器的网址则变为abc.XXXX.com

命令行实在不在行啊，想找luci用，看到这里有2个但是必须配合1.25，应该怎么解决？

Sublime+Sublimelinter有一堆leak提示。
路由器的内存本来就少，不能这么浪费吧。。。

这个客户端如何把自签的证书编译进去？

编译了最新版ngrokc v1.44-(2017/07/25)，服务端是Ubuntu 16.04上通过apt-get install ngrok-server安装的，运行时提供了受信的SSL证书

HTTP和TCP channel都能正常使用，但HTTPS始终得不到客户端的数据返回，请问可能是什么原因？

另外，我看到有文章提到需要提供一个config文件，里面配置trust_host_root_certs，但ngrok-c貌似并不支持config文件输入

1、先编译openssl（buildlib.sh无法成功编译，后修改了Makefile编译成功），CC=mipsel-openwrt-linux-g++，生成了libssl.a和libcrypto.a，拷贝至ngrok-c-master目录。
2、修改openwrtbuild.sh，出现报错，求助！！！谢谢。

嵌入式设备 应用这个转发模块 当连接的路由器更换/重启，获取dns失败，转发失败？没有相应的判断处理吗？int net_dns( struct sockaddr_in *server_addr, const char *host, int port ) 返回-1！

I try to compile the ngrok-c client for my WNDR3800 Router which runs openwrt CC(14.07). I was using the VPS which runs Ubuntu 14.04 for the work. I followed every step you mentioned and still get the error information....Could you please help sort it out? Many thanks.

我们需要修改openwrtbuildv2.sh文件，将第二行和第三行环境变量环节注释掉，然后将CC改arm-linux-gcc具体如下图所示

这种方式最简单！！！！

!/bin/sh

export PATH=$PATH:'/home/cijliu/work/asuswrt-merlin/release/src-rt-6.x.4708/toolchains/hndtools-arm-linux-2.6.36-uclibc-4.5.3/bin'
export STAGING_DIR="/home/cijliu/work/asuswrt-merlin/release/src-rt-6.x.4708/toolchains"

mkdir $DIR

搭建好asus-merlin编译环境之后，设置PATH和STAGING_DIR路径，然后从PATH下找到对应路由器版本的CC编译器名称并在本脚本中修改。

另外，大神您提供的简书教程中，忘了提示编译者修改CC编译器那一步了~~~

非常感谢您的工作，让我能用上最新版本的路由器客户端，哈哈

自己改了一个纯C的（在ubuntu中运行还算正常）移植到嵌入式系统中，同时有超过5、6个连接时就会崩溃，不知道从哪个方面入手查错。
还有没有人有纯C的ngrok啊？

如题ngrok.cpp:279:23: error: iso c++ forbids comparison between pointer and integer [-fpermissive]

环境为网件4300v1，OpenWrt CC 15.05.1 r49389，用的ipv6线路，一直刷update dns，域名和线路都是通的，添加hosts也不行，换成ipv4的域名就ok了

我这边下载了lede-sdk-17.01.4-bcm53xx_gcc-5.4.0_musl-1.1.16_eabi.Linux-x86_64.tar.xz 和ngrok-c
并参考Openwrt-Ngrokc编译教程
因为型号不同所以将相应的openwrtbuild2.0.sh修改为

分别尝试了4个GCC都无法找到。
不知道是不是缺少了什么东西？

我的服务器有验证Password功能,我看客户端默认是空的,所以只能把服务器的密码设置空才能,能不能添加一个参数,让运行时可以验证Password

我自己编译了libpolarssl.a ，但不管是放在工程目录还是建的polarssl目录下都无法编译成功，提示是编译nonblocking.cpp或sslbio时失败，将这些文件中的include<polarssl/xxx>都改为""还是不行，求指导

我在用ngrok-c的过程中发现，有时ngrok服务器重启或者ngrokd进程死掉后，再启动ngrokd时，发现ngrok-c不能自动重新建立通道，如果正常使用中断网又恢复后，能否自动重连？

能加入自动重连的功能吗？
在openwrt下，3G网络
先执行ngrokc，tcp模式，本地端口22
用ifdown 3g关闭网络
10s后开启网络ifup 3g
等待拨号成功
拨号成功后，发现远程通道未恢复

最后给你一个openwrt的编译包。
这个包在放在源码编译目录的packages目录下
或sdk编译目录（packages）下都可以用。
只是放在sdk编译目录下时，需要解除依赖（比如openssl）
或将源码包和packages的feeds中的相关工程包（比如依赖的openssl）
拷贝到sdk的packages目录下即可编译
