We ran into this issue last week with several legacy applications we soon hope to commit to the bone yard...

I haven't read the article yet,... but would be nice if it is available on Windows -

However, that said. I can just set up a VM and run there.... I don't do a massive amount of managing Linux Servers, but sometimes it would be helpful..

Not even on most Linux yet.

Oops. :-)

Just as a comparison, here's what it would look like with Ansible:

name: Recursively own html files file: path: /var/www/html owner: apache group: apache state: directory recurse: yes

@matteo-nunziati said in Anacron Jobs on a CentOS 7 Server:

@JaredBusch well never considered the workload on servers. I don't know how they manage it! maybe not so many use unattended upgraqdes in debian.

I definitely feel like Ubuntu users don't keep their systems as up to date ;)

/proc/version usually has pertinent information across most systems.

Edit: I looked closer. It's just the OS name (RHEL/Ubuntu) and kernel version. Never mind.

So that is where we are now. A missing package, unclear documentation and yum unable to resolve dependencies for some of the remaining packages. As the support community showed no interest in Kopano being used in production and actually got angry that we wanted to, we decided to halt here. But there is the documentation in case anyone runs into this and wants to pursue it further.

Planning to test this out soon.

Interesting: Fedora 25 starts to panic with RAM < 512MB at the beginning of the kernel init phase, even in text mode. Just had a look at the manual which clearly says that Fedora requires 1GB of RAM.

Looks like I'm out of luck and have to stick to Ubuntu / Debian.

Another thing to note is with RHEL/CentOS 7.3 they recommend a 1GB boot partition instead of 512MB.

Just an aside.

Should work as long as you keep an eye on it. Ubuntu for example likes to keep old kernel and initrd images there until you clean them up (e.g. apt autoclean etc)

Ya I usually keep 3 and remove the others but I think the images are getting big enough they needed to adjust the size. If you do anew install it defaults to 1GB.

To make what?

Fixed

In case anyone else is wondering, you can easily schedule OS ticket to fetch emails, by setting up a cron job that "runs" the cron.php file in the OSTicket directory. Just open up /etc/crontab and enter this line:

***Assumes your php directory and OSTicket install are at the locations specified below.

This causes OSTicket to poll the mailbox that is defined in the OSTicket email setup area in the OSTicket GUI, every 5 minutes.

Did anyone ever figure out if there was a way to setup files for firewalld? Or was the XML service files the way to go?

XML I think.

That's what I was afraid of. We're using IPTables on all of our OEL7 servers right now but I think moving to the default firewalld may be a good idea. I'll have to look into the XML config and see how much more difficult, if at all, it is over the IPTables file. It's a shame we can't just copy a single file around anymore but the XML files probably won't be too much more difficult.

Ya it's not bad at all. Here's the config from my Identity Management server. It's pretty similar to /etc/sysconfig/system-config-firewall on RHEL 6, just in zone specific XML files.

<zone> <short>Public</short> <description>For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.</description> <service name="http"/> <service name="https"/> <service name="ntp"/> <service name="dhcpv6-client"/> <service name="kerberos"/> <service name="ldaps"/> <service name="ssh"/> <service name="dns"/> <service name="ldap"/> </zone>

Those services are predefined right? You can also build your own services via the same process.

Ya and you can define specific ports. I prob could have grabbed a better example.

No, I think I've got it just need to investigate actually setting these up.

I'm running the same version on Ubuntu and mostly idle CPU utilization and disk usage here.

@travisdh1 said in Installing Linux Malware Detect and ClamAV on CentOS 7:

Any reason to use LMD instead of or in addition to rkhunter?

Doesn't rkhunter focus only on root kits?

Mostly, but this was the first time I remember hearing about LMD.

@scottalanmiller Also, using just using the root domain name for the conf file name is potentially confusing depending on how much you are hosting.

Even for my gaming website, I have a bunch of sub domains setup.

www.daerma.com.conf goes to the root and www.
oc.daerma.com.conf is owncloud
obelisk.daerma.com.conf is my nodeBB forum

That does not even get into what do you do about the ones that you have multiple TLD names for such as .it, .com, .org, etc.

I can't believe that they don't have a RHEL package at least!

@NashBrydges said in Installing a Basic LAMP Stack on CentOS 7:

@scottalanmiller I haven't yet. About to give it a try. Stuck to legacy since that was what I was reading everywhere.

Where is everywhere? Technet says to not use legacy.

https://technet.microsoft.com/en-us/windows-server-docs/compute/hyper-v/supported-centos-and-red-hat-enterprise-linux-virtual-machines-on-hyper-v

Legacy is a fallback driver that you never want to use, it's low performance and high overhead. If you needed that for CentOS, it would make Hyper-V a silly, non-production ready platform. But Hyper-V is a good, solid performer.

Not only that, but I install all of my CentOS 7 VM's as Generation 2 when on Hyper-V they work perfectly with default settings for everything except secure boot. Uncheck secure boot. Everything else is 100% default settings.

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!

@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.
