AIX 昨天SSH还可以登录 今天缺无法登录 但是telnet却可以登录

# stopsrc -s sshd
0513-004 The Subsystem or Group, sshd, is currently inoperative.
# startsrc -s sshd
0513-059 The sshd Subsystem has been started. Subsystem PID is 33358020.
#  telnet localhost 22
Trying...
telnet: connect: A remote host refused an attempted connect operation.
# ifconfig -a




ssh [email protected]
输出如下：
#[/]lssrc -s sshd
Subsystem         Group            PID          Status
sshd             ssh                           inoperative
#[/]startsrc -s sshd
0513-059 The sshd Subsystem has been started. Subsystem PID is 824454.
#[/]lssrc -s sshd
Subsystem         Group            PID          Status
sshd             ssh                           inoperative
在起ssh的进程时似乎就有异样

ssh的配置文件是不是有问题，看看日志。
