SG-3100 switch weird behavior (resolved)

@johnpoz said in SG-3100 switch weird behavior (resolved):
so another work around might be to use TCP for your syslog ;) Then there would be acks and switch would know that IP.. I don't believe pfsense can send tcp syslog though, at least not with the default. Not sure if the syslog-ng package would allow for that?
That would work but I don't think there is TCP for that purpose, at least that I'm aware of.
The raspbery pi 4b is a 4GB model, so its not much for a syslog server in which there is everything indexed for fast search.
It is using elasticsearch for that task.
The ping cron job is pretty light for a network and RAM usage perspective, so I'll stick with this option.But yes, something running TCP would have solved that too..
Graylog is a very powerful tool to have in the network, take a look at my dashboard :)
I can search everything, things such a mac address, an IP, a port, a device who accessed a network folder, unifi devices logs, use a firewall rule Tracking ID to see if some user matched that rule and what time it happened.. There is no limit, really.

@stephenw10 maybe the unifi switch uses just a much longer cache timeout value. I would think switch cache timeout would be of decent length to be honest.
My cisco's have a 5 minute default.

It could be, unfortunately the unifi switch mini is pretty basic, there is no SSH access or something like that, that means that everything you can do with it its located in the controller's GUI..
To adopt it, I had to use an option 43 string in the DHCP options because there isn't a way to SSH to it and use the set-inform..
Edit: What I was thinking when I designed this network is to have low power usage and speed..
1 - Synology NAS DS218+
2 - Raspberry Pi 4B
3 - Raspberry Pi 3b
4 - NanoHD
5 - Switch mini
6 - SG-3100 -
@mcury yeah I am well aware of graylogs power ;) hehe
If your bored, or want to give back. There are prob some interested users here that could benefit from a walk thru on how you setup your system..
edit: yeah I picked up one of those flex mini's to play with.. I run unifi APs, etc. I wasn't overly impressed with it. Its tiny, it can be poe powered, its cheap... I could see some very valid use cases for it. I was planning on replacing the little smart switch I have behind my tv with it.. Just haven't gotten around to it as of yet - so for now it sitting on my shelf..

Sure, I can share everything about it, I'll prepare something to post here on how to configure it and use it in a Raspberry Pi :)
I can see that happening already, a bottle of coffee and keyboard stroke sounds :)

It is a nice little device, it does the job and it is nice for small places, specially if you need PoE.
I'm happy with it to say at least, of course I miss my old Cisco days :) -
@mcury once you put it up, I will give it a go via a VM maybe. I don't as of yet have a pi4 to play with.. Been looking for an excuse to get one hehe.. But they have been hard to find as well, I would prob go with the 8GB ram model as well.
My current pi's most likely under powered to run graylog for sure, even if strip down to bare essentials for stuff.
edit: yeah I had some stuff connected to it just in my computer room (home office) hehehe I was seeing lots of disconnects and reconnections.. Trying to recall what was causing it now, have to see if I put that info up here or might of been another forum.. I for sure agree for the price its a very handy little switch to have.
It wasn't actually disconnecting - if I recall it was something to do with it seeing different IPs for pfsense because of the different vlans that were trunked through it - and how pfsense uses the same mac for different vlan interfaces..

Raspberry Pis are to expensive right now, there is a shortage on the market, go for the VM for now and when the prices are OK, you get one
I'll prepare that, I have some .txt files full of things to share about Graylog.
8GB would be much better than 4GB, you would be able to gather much more data.
Here 4GB is enough for 3 days of logs only.. But that would also depend on how much messages your Graylog server receives per day.Sure you can optimize the firewall rules to don't log everything too, like connections for the firewall IP port 53 for an example..

@mcury oh found that thread were talking about the disconnects.. If your interested ;)

Pretty sure that was thread that got me to get the mini ;) hehe

I read that thread, you helped me to decide about getting one for myself. :)
You were drinking a beer hehe -
@mcury said in SG-3100 switch weird behavior (resolved):
You were drinking a beer
That is something I do quite often, if not bourbon or scotch heheheh or of late been doing martini's I mix it up sometimes vodka sometimes gin. I found they great stuffed olives with garlic and jalapeño heheh

eheh, who never? :)
I have been drinking Amstel, its a Lager beer -

Yeah I know Amstel ;) Light is currently my day to day beer.. Its got decent flavor and about half the calories..

Today is a good day for a beer, too hot over here..
I received a few guests last weekend and they came from another state, so I didn't ask them to bring their own beer..Next time I'll ask them to stop at the market, otherwise no beer. :)

Done, english is not my first language so I hope its okay.
