@FreeMindedCH said in RAM Disk Settings: What RAM disk sizes would you recommend for a Netgate SG-2440? Any idea why the very same installation does not show this behaviour an a PCEngines APU? Hi, Why would you want to use a RAM disk? is it very important to have in your system....? in front of me a colleague described very well why it is not advisable to use (especially if you have little physical RAM in your system, such as 2 or 4GB on the APU MOBO) here is a great and detailed description of @bmeeks: https://forum.netgate.com/topic/155220/swap-usage "Using RAM disks will make your problem orders of magnitude worse! Do you know what swap is for and what it actually is? Swap memory is a type of temporary RAM. When there is not enough physical RAM to hold the information the currently running processes are using, the operating system will cycle currently idle sections of RAM out to a special file on the disk. So any currently loaded process that happens to be sleeping or otherwise not actively using CPU at that exact instant can have some or all of its data removed from RAM and written to the swap file on disk to free up RAM for use by another active process. Then, when that sleeping process "wakes up" and starts execution again, the operating system reads its data from the swap file and copies it back into RAM. This is an extremely slow set of processes compared to keeping the data in RAM the whole time. So usage of swap is basically to be avoided. When you start using swap, things are going to get very slow very fast. A RAM disk uses part of RAM to hold data that is normally written to disk. So you would be taking up even more precious RAM to act as a disk drive and thus increase the operating system's need to use the swap file. You leave the OS even less free RAM to use for processes since a RAM disk reserves some RAM to be a disk drive. RAM disks today are generally a bad idea on pfSense. I suggest you avoid using them altogether. As @DaddyGo mentioned, you are using some memory intensive packages. 4 GB of RAM is really not all that much for the packages you have. Are you sure you really need Squid? With the widespread use of HTTPS today, the utility of caching with Squid is reduced unless you are using some type of MITM. Squid can use a lot of disk space, too. The ntopng package can also be quite resource intensive as an Snort. So together, all those packages can give your firewall a real workout with only 4 GB of RAM available. That's why your firewall is resorting to use swap space, and it is having trouble even with that. This is because swap space is configured during pfSense installation and is a fixed size. Your error messages indicate you are exhausting your swap file space."

Maybe I'm overcomplicating things. If the switch is mirroring the port connecting the router to the switch (thereby capturing all traffic from the router), will it even get an IP from the router and does it even need one set as a static IP? I've not seen any data from Snort for alerts in >48 hours which has me wondering. However, when I ran a packet capture, it seems to be capturing all packets.

If it wasn't 64-bit it couldn't even have made it that far, it would have had an exec format error much earlier in the boot process before loading the kernel.

okk, but its solved now :)

Thanks man. Just got there. Gunna close this. Cheers.

Thanks everyone for the responses. Everything works now. Something in an older config backup had the wrong username.

@jdeloach said in CD (ISO) installer for 2.4.5-p1 is too large to write to a cd: I use a DVD to write the ISO to instead of a CD. Seems to work just fine. I use Windows, don't know if there are issues with using a Mac. I think most folks on here use a USB memory stick but I prefer to stay with DVDs. It worked. Thanks much

Thank you for your response, I actually got it working. it was actually 65 error. How I got fixed it by putting 1500 into the MTU and set WAN interface hard code to 1 gig auto. It is working great now and I did a quick backup! I am actually running static IP that was assign to me by Comcast. Thanks

Hi @Derelict thanks for your help. I will test your recommendation soon, I had a trouble with hosting, the system crashing and I will have to reset and reinstall When I can set all good, I will test your recommendation, and I will to continue with this thread. Thanks you very much

I would suggest contact support - when I asked for an image, I had link in like 1 minute.. There is zero reason to searching around the archives of the internet.. Just contact them - you do not need a support contract for such a question And yeah its good idea to have current image, don't get me wrong... But the time for that is like when you first install it.. Just keep a copy ;) Reason I contact them is wanted factory version of lastest image for my sg4860. And then for the 3100. You use to be able to download them off the portal.. But now you can not get factory version without contacting them for new versions that come out. Is this netgate appliance, or you just using the CE version?

everything worked well and then suddenly stopped working, I am puzzled over this question which is disturbing me more than anything else, i see that i not only me encountered such a challenge but i am unlike others not. I had to be able to disable it from Console too otherwise i would need to make reinstallation..

It looks like a larger amount of RAM is taken up for paging, couild this be ZFS file system?

Hi all, apologies for the delay. Took me awhile to find another identical gigabit card to test with since cleaning the riser and card connector with isopropyl didn't work unfortunately. I also had to get a new modem from ISP since mine was way out of support. It is now working fine with DHCP, appears to have been hardware gremlins in the gigabit card and the old modem being clunky with DHCP.

@videogamingtown said in First time install - Web interface not loading?: Got it working after changing the subnet, thanks. . Glad you got it sorted out.

My PC is in network 172.23.134.0 and i can ping normally in this network. I don't know if this are being a problemm You can ping 8.8.8.8 from this network? If so then what is the problem? I cannot help if you are only going to provide little pieces of information each time you think it may or may not help. Provide a full diagram of your network and all LANs, servers (squid?), smart switches. For example, in that diagram show LAN A is able to ping 8.8.8.8 but not access a website, LAN B cannot ping and so on. Are all 3 LANs different interfaces on pfsense? Show that in the diagram.

Awesome, thanks @viktor_g :) I'm pretty new to BSD so was hoping there might be a workaround. Appreciate you taking the time to set it out

@calical So enabling the DNS forwarder resolved the issue for you as well?
