What is the purpose of 'zypper -remove patterns-openSUSE-minimal_base'
I know what it does, but is it necessary? Does this minimal_base package prevent you from installing certain packages at a later date? Or you just making things nice n neat?

It's been quite some time, but if I remember correctly it interfered with some packages that we needed as the "minimal" blocked adding a bunch of stuff.

Do they have a tui for firewall-cmd yet?

Not that I have seen.

I want to down vote RedHat.

@scottalanmiller said in Slow SSH Logins on Linux:

Often remote SSH logins on Linux can experience a lengthy delay. This is often caused by the SSH daemon on the server defaulting to attempting a DNS lookup of the SSH client attempting to connect to it. Typically we do not want this behaviour as client systems often cannot be verified in this manner but awaiting a DNS timeout can be rather annoying. Many systems configure this on by default. I see this in the Red Hat family including RHEL, CentOS, etc.

The fix is simple, just explicetly add the line:

UseDNS no

To the /etc/ssh/sshd_config configuration file. The default is “yes” and there should be a comment to this effect as well. After making the change, simply restart the SSH daemon for the change to take effect.

service sshd restart

Ran into this the other day. Windows to Linux was pretty slow, but Linux to Linux (using our Bind server) was super fast. Turned off DNS and GSSAPI and it was fine from Windows.

@scottalanmiller said in Linux: The Role of DRBD:

I added a header into the main topic list for that. But it is going to be later in the Advanced Topics, section. Oddly, I know of pretty much no standard Linux Administration tomes that cover DRBD. It's so core, very odd that it so often gets missed.

Could it be that most Linux Admin's don't know about it until they go searching for it? ...That's how I found out about it.

You would hope that the people writing the books would know, though!
