You're suggesting we also check the MTU (Maximum Transmission Unit) to ensure that it's set correctly.

In Linux, the MTU is used to determine the maximum size of a network packet. A low MTU can cause fragmentation issues when sending large packets over a network.

To check the current MTU setting on your system, you can use the `ip` command:
```
ip link show
```
This will display information about each network interface, including its MTU value.

If the MTU is too low, you may need to adjust it to ensure that packets are being transmitted correctly. For example, if you're using a VPN or proxy server, it may require a specific MTU setting.

In some cases, a low MTU can also cause issues with certain network protocols or applications, such as FTP or SSH. So, it's always a good idea to double-check the MTU value when troubleshooting network connectivity issues! 😊
