brctl missing

[togabob]

I just installed CentOS 8, and am unable to find brctl. Tried installing bridge-utils, but the package is not found by yum.

Any idea how to get brctl?

Thanks!

What do you want to do with the brctl?

You might be able to achieve the same result with tools that are available.

Same thing for me, I'm trying to play with Linux bridges in CentOS 8, but "bridge-utils" is not available. Of course I can use other tools like "ip", but I need exactly to use "brctl", it is deprecated, I think that's why it has been removed completely from CentOS 8. What will be the most correct way to bring back "bridge-utils" ?

It's deprecated and removed and the functionality is now present in either the ip bridge command or the bridge utility.

It's not coming back so you might as well accept that and work around it.

Sorry, but as far as I can see, you:
* fail to answer the question
* are close to XY Problem. See http://xyproblem.info/

I used 'nmcli' to create a linux bridge in CentOS7. You can give it a try.

My question was "What would be the most correct way to bring back bridge-utils ?"

And what kind of replies I received ?

Anyway, the main point here is that RedHat/CentOS team is breaking backward compatibility. In the past if the system doesn't contain "bridge-utils", my scripts would install it, by issuing "yum -y install bridge-utils", now bridge-utils is completely removed, this is not good at all. Backward compatibility is king, so breaking it, is a nasty thing.

[TrevorH]

Backwards compatibility is often broken at major version release times. That's when you get to make changes to cater for e.g. CentOS 7 to 8 differences.

According to https://access.redhat.com/documentation ... ctionality , bridge-utils was deprecated in 7.7 .
It is completely natural to be removed on the major release.

Using brtstl it was possible to get the spanning tree topology, for example:

Code: Select all

# brctl showstp br0

Tell me please, is there any way to get this information in rhel/centos 8 with "tools that are available"?
