Followed that yesterday and all went OK

Thanks for feedback!

Great job @scottalanmiller and welcome aboard!

Hope you enjoyed the experience!

Now if you want to play with it, I recommend you to use our CLI (http://docs.openio.io/cli-reference) or you can deploy our S3/Swift implementation (https://github.com/open-io/oio-sds/wiki/Install-Guide---OpenIO-Swift-S3-gateway).

Feel free to send me some feedbacks, I'm here to help!

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.

Way to necro a post, security and firewall ar of the upmost importance. No system ever needs to be setup open this way....

I think that he was being tongue in cheek.

Okay, I didn't get it LOL

That looks like a win if you didn't need any data from that system...

Export the Schema just in case, lol.

@DustinB3403 said in Linux: Checking Filesystem Usage with df:

Will there be a topic on "managing inode in linux"

Yes, but it is going to go into an "Advanced Topics" section. Just as LVM and MD will have high level "normal" admin sections and eventually delve much deeper in advanced sections. I want to cover everything in a "normal admin" capacity like you would learn from the RHCE up front. Then go back and cover the nitty gritty details that other admin books don't. So it will basically take two passes but the hope is that the first pass will take you from "starting point" to "competent Linux Admin" then the second part will go where normal admin guides don't tread.

It doesn't update as "new" when I just update the list. Only if I comment on the thread.

Who knows, everyone is pretty confused by this one.

Did you check the repos before calling me an ass or taking the word of some random person on a forum? I don't think so. You are so insistent that this is my fault and wanting to call me names that you are blindly willing to assume anything. Bottom line.... one official spokesperson for the company responded that the issue should not exist after asked directly if it was fixed. A random person on another forum made a comment about something that doesn't exist and you took their word for it as a reason to badger me.

Here are the full contents of the repo for those interested.

So where is the PHP7 package that you are berating me about? Please provide me the link as I cannot find it.

For those who were still having problems getting Mattermost running on CentOS 7, I was also having the same problems and couldn't get beyond the postgres install. I found another guide and with a few tweaks, I was able to get this running.

https://www.howtoforge.com/tutorial/install-mattermost-with-postgresql-and-nginx-on-centos7/

The change that was required from this guide was in the "Download and Extract Mattermost"

Instead of...
[root@mattermost ~]# wget -q "https://github.com/mattermost/platform/releases/download/v2.0.0/mattermost.tar.gz" -O mattermost.tar.gz

Use this...
wget https://releases.mattermost.com/3.3.0/mattermost-team-3.3.0-linux-amd64.tar.gz

Then in the next block, instead of...
tar -xvzf mattermost.tar.gz

Use this...
tar -xvzf mattermost-team-3.3.0-linux-amd64.tar.gz

After that, follow the guide to the letter and it will get you to this...

The "working data" that I mentioned that scrolls by quickly before our summary chart appears from this example looks like the below output. Generally we can ignore this, but it can be useful should there be an error to see where something has gone wrong.
