What Is device enp0s29u1u2 ?

Thanks in advance.

[doktor5000]

That is a wired network connection. Please show the output of

Code: Select all

/sbin/ip a
ls -al /etc/sysconfig/network-scripts/ifcfg*

Aprt from that, is there any actual issue with your network except for those messages?

[nigelc]

Here It is:

It' is still working

[doktor5000]

If you want to get rid of the error, then move away / delete or fix /etc/sysconfig/network-scripts/ifcfg-enp0s29u1u2 - this is the config file for that interface.

[nigelc]

How do I

delete or fix /etc/sysconfig/network-scripts/ifcfg-enp0s29u1u2

thanking you.

[doktor5000]

If you want to fix it, take a look at the content of it using e.g.

Code: Select all

cat /etc/sysconfig/network-scripts/ifcfg-enp0s29u1u2


and fix what's wrong, or post the content here, along with some context information.

If you want to delete it, simply delete it

Code: Select all

drakconnect --del

or if that interface is not offered there then delete it manually

Code: Select all

rm -f /etc/sysconfig/network-scripts/ifcfg-enp0s29u1u2
