julyclyde http://www.openssh.com/releasenotes.html OpenSSH 6.7/6.7p1 Changes:Support for tcpwrappers/libwrap has been removed.
[root@RHEL openssh-6.6p1]# ./configure --help | grep with-tcp-wrappers
--with-tcp-wrappers[=PATH] Enable tcpwrappers support (optionally in PATH)
[root@RHEL openssh-7.9p1]# ./configure --help | grep with-tcp-wrappers
[root@RHEL openssh-7.9p1]#
SSH 官方说 6.6 之后版本不支持 tcp-wrappers,但 CentOS7.6 自带的 OpenSSH7.4p1 版本是可以支持 tcp-wrappers,所以想知道这是如何实现的,并希望通过自行编译升级 OpenSSH 7.9 的时候恢复这个功能。
