Does anybody know, or has anybody worked with Korenix JetNet 4508v2? This Switch has a very important Bug in the Firmware. SSH is working fine, but for a period of time. Then, ssh is not working anymore, and unfortunately you dont have direct access to the switch. I am working remotely, and i have to call the Colleague there to restart the Switches. Can anyone suggest any solution to this issue? Thanks in advance.
As stated in the comments you can't solve an problem inherent in the hardware/firmware if there's no update fixing it. Latest firmware seems to be 1.4a and possibly the 5 year warranty isn't over yet, so you could RMA.
However, you can work around - either
- replace the faulty device (best)
- reboot by scheduled script before the problem comes up (only possible when it's predictable)
- reboot by other means if SSH is dead (telnet, serial, ...)
- connect the device to a PDU where you can remotely toggle the power; this can also be done automatically by a monitoring script
