1. administratively prohibited: open failed

    用 SSH 打了一个洞,然后发现这个错误:

    1. [[email protected].io ~]# ssh [email protected].8.8.8 -D 0.0.0.0:9999
    2. channel 2: open failed: administratively prohibited: open failed
    3. channel 3: open failed: administratively prohibited: open failed
    4. channel 4: open failed: administratively prohibited: open failed
    5. channel 5: open failed: administratively prohibited: open failed
    6. channel 4: open failed: administratively prohibited: open failed
    7. channel 5: open failed: administratively prohibited: open failed
    8. channel 4: open failed: administratively prohibited: open failed
    9. channel 5: open failed: administratively prohibited: open failed
    10. channel 16: open failed: administratively prohibited: open failed
    11. channel 17: open failed: administratively prohibited: open failed

    查看一下错误日志:

    1. [[email protected].io]# tailf /var/log/secure
    2. Jul 28 21:15:46 bwg sshd[5158]: error: connect_to driver.google.com: unknown host (Name or service not known)
    3. Jul 28 21:15:46 bwg sshd[5158]: error: connect_to driver.google.com: unknown host (Name or service not known)
    4. Jul 28 21:15:47 bwg sshd[5158]: error: connect_to driver.google.com: unknown host (Name or service not known)
    5. Jul 28 21:15:47 bwg sshd[5158]: error: connect_to driver.google.com: unknown host (Name or service not known)
    6. Jul 28 21:15:48 bwg sshd[5158]: error: connect_to driver.google.com: unknown host (Name or service not known)

    嗯,域名写错了,那肯定访问不通的,应该是 drive.google.com

  2. 通过跳板机访问内部机器

    1. [[email protected].io]# ssh [email protected]目标机器ip -p 22 -o ProxyCommand='ssh -p 22 [email protected]跳板机ip -W %h:%p'
