我在基于Linux的服务器上运行NetExtender以连接到另一家公司的专用networking。 连接工作正常，但在一个月内，如果连接丢失，它不会自动重新连接。 该程序被configuration为在连接终止时自动重新连接，它尝试重新连接但不成功。
如果我手动login到服务器并closuresnetextender，然后重新启动，它工作正常，但我需要此程序始终运行。
以下是断开时的日志

谢谢
有时会断开连接，但客户端应该能够每次重新连接。 我认为这是NetExtender客户端的问题。 我们之前在Linux上遇到了问题，唯一的解决方法是等待Sonicwall发布更新的客户端！
由于手动重新启动它可能工作，也许解决方法是使用监视服务（如监视）来检查连接？ 例如，Monit可以每分钟在通道的另一端ping一些东西。 如果没有回应，Monit可能会杀死并重新启动连接。 http://mmonit.com/monit/
一个示例monitconfiguration将是
check host myserver with address 192.168.1.1 if failed icmp type echo count 2 with timeout 10 seconds then restart start program = "/bin/bash /home/me/netextender-startup-script.sh" stop program = "/bin/bash /home/me/netextender-stop-script.sh"
您必须根据您的Linux发行版来定义启动和停止脚本…
