@dashrender What do you mean by this? Usually the people who say things are too "Preachy" use words like cuck and SJW in casual conversation, and are ok with the current crop of concentration camps that exist in America today.

@jaredbusch Ok thanks doing that now.
They do this quickly, i got the ticket open and closed in less than 30 minutes.
But what about the config?

Not once in 10 years have i had to change this setting for an Outlook user.
Not even people with 15GB mailboxes who have never erased an email from Inbox or Sent folder.

Have a LAMP server on vultr. It needs to be able to send mail to our office.
Never setup postfix before.
is it
sudo apt install postfix
Choose Internet Mail
Choose myworkdomain.com when it asks
sudo ufw allow postfix
sudo systemctl restart ufw
Add the ip to my spf.
Then something like php mail() will work?

Looks like this for Dark Theme users

Where's the Comic Sans version?

Ive got this sorted now. The file i was editing was snmp.conf
This was wrong, as the file setting up the snmp listening daemon, what you are going to query from your nms, is snmpd.conf.

I looked at what engineer gave me and made some modifications to what i was doing.
This is a basic config that you can put in /etc/snmp/snmpd.conf and have it work with an NMS.
There is a ton more stuff like Version 3 and some other things you can do, but for my purpose this is just fine.
There are some configurations that are pages long, but this one just gives your nms the ability to query anything in the standard .1 subtree, at least i think that is what is happening.

@dashrender 3.5 each way to work, occasional road trips.

My 2001 has a bit less than 108,000 miles. Drive it every day.

I will. Kind of embarrassing, i work for a company that specializes in linux devices and snmp. I broke down and went to one of the engineers here, asked him to send me snmp configs from one of our models. First time i think am asking them for help instead of other way round.

Why would anybody go to the kwikemart, buy lottery tickets with their own money, then put them in the company Mega Millions pool?

Does anybody actually know how to set this up for a Linux box?
In Windows, I install the service. Then I open the SNMP service, type in a read only name and the allowed hosts, the ip/dns of observium/opennms. Then in observium/opennms I type in the name of the Linux box and the read only name. That is it. snmp data flows, charts are drawn, alerts can be sent.

In Linux, I install snmp, then goto /etc/snmp/ and see there is 3 files here, snmp.conf, snmpd.conf, snmptrap.conf.
Then I goto net-snmp.org and read about it.
http://www.net-snmp.org/wiki/index.php/Com2sec The !@#$ is this, com2sec?
Then they give this example conf file. Ok but using this snmp.conf doesn't actually let me add the Linux box to my observium/opennms.

# Map 'disks' community to the 'disksOnly' user
# Map 'everything' community to the 'allThings' user
#         sec.name   source    community
com2sec   disksOnly  default   disks
com2sec   allThings  default   everything
 
# Map 'disksOnly' to 'diskGroup' for SNMP Version 2c
# Map 'allThings' to 'allGroup' for SNMP Version 2c
#                sec.model sec.name
group diskGroup   v2c      disksOnly
group allGroup    v2c      allThings
 
# Define 'diskView', which includes everything under .1.3.6.1.2.1.25.2.3.1
# Define 'allView', which includes everything under .1 (which is everything)
#                  incl/excl   subtree
view    diskView   included    .1.3.6.1.2.1.25.2.3
view    allView    included    .1
 
# Give 'diskGroup' read access to objects in the view 'diskView'
# Give 'allGroup' read access to objects in the view 'allView'
#         group     context   model   level    prefix  read       write   notify
access    diskGroup   ""      any     noauth   exact   diskView   none    none
access    allGroup    ""      any     noauth   exact   allView    none    none

What is source? Is that where I put in the name or ip of my observium/opennms?
I know view acces group, wtf is com2sec. How do I get a Linux box to connect to an nms like opennms/observium?

Probably because dank weed doesnt exist in the midwest or northeast.

The USCERT has been very busy this week, sending out a couple dozen alerts.
https://www.us-cert.gov/ncas/alerts/AA18-284A
This one is interesting, it details readily available and legit tools that are used in exploit attacks around the world, includes usage examples and mitigation.

There is Snip and Sketch, the replacement for Snipping Tool.
Not sure at all, but the only difference between these two i see is the toolbar, and the Sharing option.

I wish the Sharing part would recognize i have Nextcloud installed and give me the Share with Nextcloud option, but it only shows MS options here.

Apparently : are used all the time in Mail From and Rcpt To addresses these days from people like sendgrid. This is news to me; I dont think this is in the RFC. Just had to update our mail rules.

I have been setting up snmp monitoring for the every device at work. I am mostly done with the setup and testing, just need to roll it out.
One thing that really needs addressing in all of these products(observium, nagios, sw, every other one) is network adapters. Specifically the fact that all these products think my desktop, and all other desktops have a couple dozen network adapters each. where is this information being gleaned from? Why cant i see 25 network adapters in my desktop?
Currently listed for my desktop


Just ridiculous.
This desktop has exactly 2 physical nics, not 25.
Here is a view of all adapters from control panel

4 listed here, because i have a vpn client and virtual box installed along with 2 physical nics.

Are you all stoners or something? That is the only time i hear the word is in reference to smelly weed; in general it refers to a musty smell.

I installed it on my workstation and one remote user until they pulled the update due to it deleting folders and files in some cases.
