Question

bash脚本尝试通过以下方式连接远程主机：

CNX=$(bash -c 'exec 3<> /dev/tcp/'$OPCION'/'22';echo $?' 2>/dev/null)
   if [ "$CNX" = "1" ]; then
     telnet "$OPCION"
   else
      ssh -vvv "$OPCION"
fi

但它完成了这个错误：

ssh_exchange_identification: read: Connection reset by peer

[myuser@vmlnx01 .escrip]$ ./menu

Usar CRTL + C para salir.

连接到没有脚本的远程主机成功：

^C[myuser@vmlnx01 .escrip]$ ssh RemoteRouter

ACCESO RESTRINGIDO

myuser@RemoteRouter's password:

远程主机是路由器，它显示此日志：

RP/0/RSP1/CPU0:Apr  5 03:55:46.210 : SSHD_[65590]: %SECURITY-SSHD-6-INFO_GENERAL : Client 10.108.120.4 closes socket connection
RP/0/RSP1/CPU0:Apr  5 03:55:46.211 : SSHD_[65590]: %SECURITY-SSHD-3-ERR_GENERAL : Failed in version exchange

SSH连接问题仅由bash脚本引起
