本文主要是介绍用strace工具来解析ssh的登录密码，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
首先要开ssh服务，查看一下。。
root@unbuntu:/etc# ps -ef |grep ssh
root 3996 1 0 13:51 ? 00:00:00 /usr/sbin/sshd
root 4463 3996 0 15:04 ? 00:00:00 sshd: nova [priv]
sshd 4464 4463 0 15:04 ? 00:00:00 sshd: nova [net]
root 4466 4310 0 15:04 pts/1 00:00:00 grep ssh
root@unbuntu:/etc# strace -p 4464
Process 4464 attached – interrupt to quit
select(4, [3], NULL, NULL, NULL) = 1 (in [3])
read(3, “/210/270/232z-/231lh,/341_/377/351/22X.tNVHFw/25=/310/235″…, 8192) = 144
write(4, “/0/0/0/17/v”, 5) = 5
write(4, “/0/0/0/nnovaserver “, 14) = 14
read(4, “/0/0/0/5″, 4) = 4
read(4, “/f/0/0/0/1″, 5) = 5
write(4, “/0/0/0/0011″, 5) = 5
read(4, “/0/0/0/t”, 4) = 4
read(4, “2/0/0/0/1/0/0/0/0″, 9) = 9
write(3, “/243/273r</267/245F/374/201H(|~>f/36/337/306/367/341/374″…, 32) = 32
write(4, “/0/0/5//31″, 5) = 5
write(4, “/0/0/0 /206/347/3/357/16/223/315/23_/267;/32/231/325/263″…, 1326) = 1326
exit_group(0) = ?
Process 4464 detached
上面解析到的就是我的ssh服务的密码，对应的用户是nova… [好害怕...]
上面这些需要开一个ssh的client来验证…
nova@unbuntu:~$ ssh 192.168.150.244 [回车]
nova@192.168.150.244’s password: [确认对端已经监听，解析 strace -p pid ]
Linux unbuntu 2.6.24-19-server #1 SMP Wed Jun 18 15:18:00 UTC 2008 i686

剩下的，你就可以看你的密码了，其实还有别的工具，truss…
strace -p $(ps -ef|awk ‘/ssh nova@192.168.150.244/&&!/awk/{print $2}’)
