Build sftp with openssh in linux (including note) and opensshsftp
To build sftp, three parts are required: zlib (including zlib, zlib-devel), openssl, and openssh. The required rpm packages are available in csdn.
1. openssl is installed in general linux systems, including rehat and centos.

OpenSSH is a free open-source implementation of the SSH Secure SHell protocol. It uses secure and encrypted network connection tools instead of telnet, ftp, rlogin, rsh, and rcp tools. OpenSSH supports SSH protocol versions 1.3, 1.5, and 2. Since OpenSSH 2.9, the default protocol is version 2, which uses the RSA key by default.
1. Why is SSH used?
Using
Recently several hosts on line, on the line of the host in the security compliance scan, found the following openssh vulnerabilities. A few of them are old-aged vulnerabilities, mainly cve-2014-1692 vulnerabilities (OpenSSH schnorr.c vulnerabilities) for the new vulnerabilities of the January. Because the host does not have an extranet connection configured, and for different versions of SuSE and Redhat, it
