使用VPS搭建的翻墙用VPN在最近一次系统升级后经常出现连接断开和无法连接的现象(619等错误),
调查了linux的系统日志(syslog),发现每次连接失败都会出现以下日志内容,
GRE: read(fd=6,buffer=80504c0,len=8196) from PTY failed: status = -1 error = Input/output error, usually caused by unexpected termination of pppd, check option syntax and pppd logs
CTRL: PTY read or GRE write failed (pty,gre)=(6,7)
CTRL: Reaping child PPP[13354]
CTRL: Client XXX.XXX.XXX.XXX control connection finished
