15.7 Legacy Series / Re: CPU usage

« on: July 19, 2015, 03:59:34 am »

Hello

Yes I´m using a realtek onboard NIC and using only Firewall, DHCP and DNS Forwarder.

I´m aware that the load will fluctuate according to traffic, but it´s almost constant, I’ve checked the RRD graphs, it was almost constant for hours.

As I have said before, once I had a load of 75% constant with no traffic at all.

Since the reboot yesterday, the firewall stopped working, WAN cannot connect to the Gateway, no matter how many times I reboot same result and there was no change in configuration. The LAN works normally.

The log is full of messages like this
“kernel: arpresolve: can't allocate llinfo for 192.168.25.1 on re0_vlan400”

One detail, it´s a system with a single NIC, so I´m using VLANs for WAN and LAN.

I´m really thinking about reinstalling the system.

New TOP -SH from this morning.

now the reported usage is 50% with even less traffic than yesterday.

Here it is.

Am I right to believe that php-cgi is the culprit?

15.7 Legacy Series / Re: CPU usage

« on: July 16, 2015, 10:02:25 pm »

There´s no VPN in use and the Traffic is about 2mbits both ways right now.

Yesterday it was 40mbits DOWN and 1mbit UP with about 1% usage and load averages at 0.

Checking now it´s still reporting 25%.

How should I track which process is the culprit?

15.7 Legacy Series / CPU usage

« on: July 16, 2015, 04:30:22 pm »

Hi, I´m having an a strange issue, after say 2 days of usage the Firewall starts do report constant CPU usage of 25%, before it was almost constant at 0%~1%, this with more traffic than now.

Occasionally I´ve seen reported usage of 75% with absolutely no traffic.

On both cases a reboot returns the usage to 0% for a few days.

This is on a quad-core i5 2Ghz

Any Ideas?

Thanks in advance.

What I actually want is to update the NO-IP dynamic DNS when it happens, the script help to know it happened, but how do I call this update from cron?

Sorry but I am a newbie to OPNSense.

Thanks

15.7 Legacy Series / [SOLVED] Help with Dynamic DNS

« on: July 07, 2015, 02:22:22 am »

Hi, First post here.

I setting up a Firewall for my home network, and having some trouble with dynamic DNS updates.

I am forced to use an ISP provided router that can´t be set as a bridge, so I set the firewall as its DMZ, as far as forwarding ports its working OK. But since the firewall WAN port have a never changing IP address, when the ISP changes my external IP, I´m forced to manually force the Dynamic DNS update to set it to the new External IP or it still points to the old IP.

There is some way to make it update say like every 5 minutes?

Thanks in advance.
