两台虚拟机，一台redhat，一台Debian ，从 redhat登陆到Debian（192.168.110.114）- [root@compute3 ~]# cat /etc/redhat-release
- Red Hat Enterprise Linux Server release 7.1 (Maipo)
- vyatta@vyatta:~$ cat /proc/version
- Linux version 3.10.83-1-amd64-vyatta (abuild@build-worker3) (gcc version 4.4.5 (Debian 4.4.5-8) ) #1 SMP Wed Jul 8 03:22:17 UTC 2015
把以上的修改都做了，现在卡在 debug1: Local version string SSH-2.0-OpenSSH_6.6.1 和 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.5p1 Debian-6+squeeze5 之间了，
就是显示完Local version string SSH-2.0-OpenSSH_6.6.1要等好几秒才显示debug1: Remote protocol version 2.0, remote software version OpenSSH_5.5p1 Debian-6+squeeze5
整个ssh过程大约要个好几秒才能出现输入密码的提示。
其他的从各个版本的redhat和各个版本的centos互相ssh登陆都是秒开，唯独这两个虚拟机，难道是Debian系的和redhat之间的问题？搞不明白问题出在哪里了- [root@compute3 ~]# ssh vyatta@192.168.110.114 -v
