我们有带有RedHat 6.5操作系统的linux机器。
当我们试图在端口8182上打电话到本地主机时,连接被拒绝:
service iptables status
Firewall is not running
telnet localhost 8182
Connection refused
cat /etc/selinux/config
SELINUX=DISABLED
SELINUXTYPE=targeted
关于如何找到连接被拒绝的原因的任何建议,即使防火墙关闭并且selinux被禁用也是如此。
我有一个Redhat服务器(Red Hat Enterprise Linux Server release 7.2 (Maipo)),它可以在re/boot上重置iptable规则。
根据第6版文件,我执行:
/sbin/service iptables save
返回:
The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemc
我最近下载了链接中提到的代码。我的GCC版本是4.1.2。在console中开始出现以下错误之前,编译过程至少进行了一个小时。
LLVM支持声明我需要使用gcc44-c++,这在我们的机器中是不可用的:
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
# yum install gcc44-c++
Loaded plugins: security
ppsd-nonprod-base
我尝试用"g++ -std=c++11 -o w w.cpp“编译下面的程序,得到错误”cc1plus: error: unrecognized command line option "-std=c++11“”。已尝试使用g++ -Dstd=c++11 -o w w.cpp进行编译,并获得以下错误集:
In file included from /usr/lib/gcc/i686-redhat-linux/4.4.7/../../../../include/c++/4.4.7/iosfwd:41,

我按照github中的这些说明克隆并构建了boost库。
./b2命令的末尾告诉我
Boost C++库已成功构建!
The following directory should be added to compiler include paths:
/home/user/Desktop/boost
The following directory should be added to linker library paths:
/home/user/Desktop/boost/stage/lib
我应该如何处理这些文件夹?我想把boost放在“为了让gcc看到它而应该去
我目前正在努力连接一个简单的库。
我从这里编译并成功安装了G729实现,如下所示:
cmake . -DCMAKE_INSTALL_PREFIX=/usr
make
make install
当我检查符号是否存在时,它们是否存在:
nm /usr/lib64/libbcg729.so | less
....

我想在我的机器上卸载tmux。我的tmux版本是:
tmux next-3.4
which tmux给了我:
/usr/local/bin/tmux
我试着用sudo yum remove tmux卸载它,我得到:
Updating Subscription Management repositories.
No match for argument: tmux
No packages marked for removal.
Dependencies resolved.
Nothing to do.
Complete!
我的机器信息如下:

我收到了这组gcc的错误,我似乎无法从谷歌或手册页面中得到答案。对于这意味着什么或者从哪里开始寻找,有什么见解吗?
