I have all our mail going through our Spam filter. In the last 24 hours our OutgoingQueue has hit over 400. All of them are no names on sender and receiver. How do I check if a linux box has been compromised. I cannot turn it off at this point.

How can I tell if one of our linux boxes is a spam generator?

RE: UFW rules question
@Emad-R said in UFW rules question:
Ok you dont need to make any deny rules, cause by default this is working. Just put the stuff you wish to make exceoption and allow
Then this should be good?

UFW rules question
I am trying to troubleshoot some weird access on one of our webhosts. I only want 80 and 443 accessible from anywhere, I'd like 587 to be only pointing to our mail server IP, and only want SSH to be allowed from our WAN IP. Am I missing anything?

@WLS-ITGuy What version of vsphere are you running?
6.7u2
They say it is supported...

REHL 8 is - But using the drop down and selecting Fedora it says it isn't.
Either way, I'll just use REHL 8 and be done.
The drop down list told you RHEL isn't, either. Yet we know it is. ESXi is just broken.
That one doesn't actually tell me it isn't supported:
But the other RHEL one does. So clearly it's broken if it gives conflicting information. In one case, RHEL isn't supported, then RHEL 8 is. But RHEL 8 is still RHEL.
I understand. I guess they don't update the dropdown in the software

was getting things set up in vsphere to find out that Fedora is not supported
It says Fedora on the list you provided
Yes, and once you select it, the 2nd picture shows that it says it isn't supported.
OIC, lol. It says RHEL is not supported? Something is screwed up.
No. This should clear it up:

@WLS-ITGuy said in Reverse Proxy install question:
Not that it matters to me but was curious if anyone knows why?
Because there is no reason to. It's the same as RHEL. So you just choose RHEL. The whole "selecting the OS" thing is weird.
Ahh - that makes sense!
Thanks - I learned something today...I can go home now.

RE: Does 64 bit or 32 bit really matter?

Presumably the OS is 64 bit so shouldnt matter.
OK. Linux servers to start. The 32 bit app requires some 32 bit library stuff that I cannot find for Debian 9/10 so I was thinking I could install on a 32bit and go from there.
Do you need to be on Debian? Linux 32bit is a dead animal pretty much across the board. I'm assuming that this is dead software without support? What's the plan in the future as these libraries get more and more rare?
It actually isn't dead. I'm not sure why they haven't made the switch the 64 bit. They just updated the software back in June.

They are both virtual machines but not thin provisioned.

@WLS-ITGuy Are the installs big?
One is. The one server has a 200GB hard drive but is only using 16GB. The other is almost 1TB.
So why not create a "new 20GB" version of that 200GB and move the services? I could see how you'd want to save the space. But it seems like a lot of effort if only for 180GB.
Makes sense to me.

Assuming these are both Linux systems, asides from being 32-bit and 64-bit, maintaining these can't be causing you a huge amount of effort to maintain.
Not really, was just looking at dead space usage and if I could combine them with minimal issues I thought it might not be a bad idea. I can leave them as is.

@DustinB3403 said in Does 64 bit or 32 bit really matter?:
@WLS-ITGuy Are you specifically thinking to switch just because it's 32-bit? What is the driving factor here?
Just trying to see if it would be a viable option based on the issue of not able to get the 32bit lib files needed in Debian9/10.
The other software needs to be upgraded so I was thinking of killing two birds (combining servers/resources) if I could.
If it is best to keep the 64bit server separate then I can do that also.
