scp: Connection closed问题记录过程

再传输文件时，提示错误。这个问题挺奇怪的。

再看secure日志：

最后能解决办法的是，通过重新安装openssh-server安装包。再次编译的时候，不添加--sysconfig=/etc/ssh   这个参数即可。
2 ]8 G: ]8 N5 C" n
./configure --prefix=/usr/local/openssh --with-ssl-dir=/usr/local/openssl/
4 i# H, a) `) \& c保持这样即可。
9 ?* d. \/ t/ P' S5 l3 y( S不再执行rpm -e openssh-server这个操作

, L( h. P& ?8 }
后面操作这样即可；
