だから私は、リモートサーバーにsshして、その端のiperfサーバーを起動するプログラムを持っています。それが実行されると、クライアント側からそのサーバーを iperf します。
たとえば、静的に IP アドレスを指定すると正常に動作します。
p=pexpect.spawn('ssh -t -x paddy@20.20.20.20 ' + iperf)
しかし、私が使用するときではありません:
p=pexpect.spawn('ssh -t -x paddy@'+ADDRESS+' ' + iperf)
私は得る：
'pexpect.TIMEOUT'
ADDRESS は間違いなく正しく入っています。何がうまくいかないかについて何か考えがありますか？
