Logging question, see when a client disconnects?



  • I have an issue where I static mapped a PC, and it drops out after some time. I don't know when… So in order to try and solve the problem I was going to see when this happened. If it was after 20 mins when the computer when idle, or 30min, or 235 min randomly or whatever.

    Is there a way I can see the moment that a static mapped PC went "offline"?

    (Any advice as to why this is happening would also be great!)

    EDIT: This was the only connection that I had Domain Name and MAC listed out. I tool the name out and left in the MAC. Maybe Windows stops saying what the name of the device is sometimes? IDK, I'll see if that makes a difference. Still haven't been able to find anywhere to see when a specific IP stops responsing or goes offline.

    I tend to say : go check that computer why it stops being "online".

    You could use Routing => Gateways and Add a 'ping' to that IP. You will find out when it goes away - stops replying.
    The why part : check the computer.

    "offline" in Status > DHCP Leases just means there is no active ARP entry for that IP address in the firewall's ARP table.

    Right, ok, can do.



  • UPDATE: Ok… So it seems that when I skip my switch and go PC right to a port on the pfsense box, no issues. Stays up perfectly.

    So it's something in my Netgear GS108 managed switch that's causing the connection to drop at some still unknown interval.

    For some reason, I've lost the ability to get into my managed switch's config page - so I'll unplug it all and figure that out without pfsense in the way.

    I'm not sure there are going to be any relevant options in the switch's config, but we'll see!?

    The netgear GS108 is garbage. I have a GS108PE here collecting dust because it kept ceasing to pass traffic.

    I had a gs108T v1 I believe back a bit - and yeah it would just crash, where not passing traffic couldn't get to the management gui.  Then sometimes on power cycle it would just loose its whole config..

    What specific model do you have of the gs108?

    It's a GS108Tv2.

    For some reason it's config page became inaccessible via pfsense's IP for it. IDK. I'll see if I can get into it and look for power managment settings, or do a factory reset maybe. Best lead I have so far.

    If you had vlans setup on it and now stuff not working and you can not get to the gui.. And you have power cycled it - yeah it prob lost its config.



  • I didn't have VLANs set up. There are some VLAN options in the config that you can't delete but are basically blank.

    Yea, not being able to log in, then power cycle and no problem is concerning. I looked around for power options and found SLEEP and "short cable mode" which are both to save power it seems, both were always disabled.

    I'll try a factory reset and also see if there is a firmware update for it. After that…. Maybe I'll try changing ports and then replacing it.



  • Fixed it for now at least.

    Turned that port to fixed speed on the switch side (doing it on the router side didn't help) and for whatever reason, it hasn't gone down in days.
