 |
|
Is it possible to schedule an Ethernet Port to be Disable and Enable at certain times via a Script.
For example: Eth01 is Disabled at 11pm & Eth01 is Enabled at 6am.
I am not a Linux Admin and I have no idea who to write the Script. Any and All assistance is greatly appreciated.

Redfive, it worked beautifully, but I ran into one problem. I had to refresh the DHCP on the port to get the IP Address.
I tried waiting but it did not work.
Do you mind assisting me with the command to refreshing the DHCP, so that I can place it below the command to bring Up the ETH port?
And can a timer be included, for instance; 5 seconds after the port is UP.
Or a separate CRON Job that I can run 1 minute after bringing the ETH port UP?

this is so funny, not two weeks ago i implemented the exact same thing, was about to post a 'what am I doing wrong?' when I realized i needed the full command path for it to work
| Code: | | /sbin/ifconfig ETH00 down |
Might I suggest you try a static IP on your interfaces (on the setup - network page) to lessen the need to renew dhcp requests.
