【问题描述】:
目标:通过SSH连接蚂蚁矿机,发送poweroff命令。
命令:plink.exe -v -t -ssh antminer -l root -pw xxx poweroff
Connecting to 10.0.1.11 port 22
We claim version: SSH-2.0-PuTTY_Release_0.70
Server version: SSH-2.0-dropbear_2012.55
Using SSH protocol version 2
Using Diffie-Hellman with standard group "group14"
Doing Diffie-Hellman key exchange with hash SHA-1
Host key fingerprint is:
ssh-rsa 1039 xxx
Initialised AES-256 SDCTR client->server encryption
Initialised HMAC-SHA1 client->server MAC algorithm
Initialised AES-256 SDCTR server->client encryption
Initialised HMAC-SHA1 server->client MAC algorithm
Using username "root".
Sent password
Access granted
Opening session as main channel
Opened main channel
Allocated pty (ospeed 38400bps, ispeed 38400bps)
Started a shell/command
sh: poweroff: not found
Server sent command exit status 127
Disconnected: All channels closed
所以连接工作正常,是命令的发送出错了。 以下是应该发生的情况:(这次手动发送命令)
命令:plink.exe -v -t -ssh antminer -l root -pw xxx

The system is going down for system halt NOW!

FATAL ERROR: Server unexpectedly closed network connection
有人知道为什么通过 plink 发送命令“poweroff”会失败吗?
