FreeBSD is a free Unix-like operating system that is a direct descendant of BSD. FreeBSD contains a significant collection of server-related software in the base system and the ports collection, it is possible to configure and use FreeBSD as a mail server, web server, Firewall, FTP server, DNS server and a router, among other applications. Although FreeBSD does not install the X Window System by default, it is available in the FreeBSD ports collection. A number of Desktop environments such as GNOME, KDE and Xfce, and lightweight window managers such as Openbox, Fluxbox and dwm are also available to FreeBSD.

I am trying to install FreeNAS from a USB on a server and am running into all sorts of problems. I have used UNetBootIn, Universal USB Installer, and ISO to USB to try to get the ISO on the stick, but they don't boot because there is a missing boot loader. So I did a search and discovered that the only way to install from a Windows computer was to use Win32 Disk Imager. However, that required an .img file and all I had was an ,ISO file. So, I used PowerISO to make a .img file from the ,ISO file. This resulted in:
Can anyone provide any insights into how I am supposed to be doing this?
No /boot/loader
FreeBSD/i386 boot
BTX halted

Yesterday I installed FreeBSD on a virtual machine with some web tools to use as a hobby webserver.
My project includes perl scripts, but when I try to run them in my browser a get the whole script shown as a text, instead of getting executed as a program.
So I did some digging and found that I had to do some CGI configuration. So I added the line AddHandler cgi-script .pl to /usr/local/etc/apache24/ht
I am using a web interface for the server called webmin, if that could be of importance.
Thank you for helping!

How to create a md (memory disk) file in freeBSD,
basically I want to keep / ( root ) in memory and hence I want to use memory disk ( md ). Also I want to ensure that it's like that boot over boot

Hello,
I use FreeBSD ipfw, I want to measure current speed in bytes per second and packets per second for monitoring.
If I have a pipe and two queues in it, ipfw doesn't give current speed when executing 'show'. If I try to measure speed by counters (ipfw rules), I don't get real speed because counters measure queue input, some packets can be dropped in queue or pipe.
Please, help.

Hi,
I created a few different zpool configs on ZFS using FreeNAS and I'm trying to figure out a way to reliably benchmark the performance.
I first tried it from a remote host connecting to an SMB share. In Windows I can't get any higher than 60 MBps. Both using a normal file copy (big file) and using various benchmarking tools. On linux I tried filling up a file using
to a smb mapped drive using a simple dd if=/dev/zero of=/mnt/cifs-share1/test1.
On to the host itself: So far I tried the default way using iozone which ships with FreeNAS. But the results seem to be high to be true so the question is how do I do it reliably and how to interpete the results?
The result I'm getting is:
sudo iozone -i 0 -R -l 5 -u 5 -r 4k -s 10G | tee -a /tmp/iozone_results.txt

Hello ,
We are building an IDS/IPS/Waf system that reads the packets from PF_Ring and apply rules to IPTables / Netfilter / Ntuple .
That software needs to access to userspace for iptables and kernelspace for netfilter. So we already pipe the both side.
But our main concern is about the performace issue. Time is our biggest enemy and need to solve the problem in mikro / mili seconds.
So where is the best place working area for our main core of software for performance ? kernel area or user area ? and why .
Thanks for information

I am sorry , i am very new on freebsd but i need help to convert this rules to pf rules. Should some one help me ?
Also is there any command like on centos to watch pf dropped / rule hitted packets like watch iptables -nvL
Thanks

Interestingly enough I have no problem using let's encrypt on Windows platform and figured it was going to be a breeze on *nix... Running into a slew of issues. For one I am trying to use certbot to facilitate this. When I issue the correct commands and webroot I see it builds the .well-known folder but it does not build the acme-challenge folder. If I try to manually create the acme-challenge folder it deletes it after the sudo certbot certonly --webroot -w /var/www/example -d example.com -d www.example.com command (with my domain info substituted of course) with the following error:

Super frustrated as everything in *nix is always easier, right? Well not this time LOL. Any suggestions would be appreciated!

Hello,
I would like to know if there is a way to create a Symlink-like file but with the difference that the file it points to gets executed when the link is read and the output is what I get from reading it.
It should work on freebsd/linux.
Thanks
Best regards

I heard iOS is tailored from FreeBSD so I'm hoping to be able to do something like
"ps -ef |grep email_client_process"
if it's not there, then restart it.
Reason is our MobileIron email+ client kept getting killed by iOS as iOS sees it
as a 3rd party/foreign process.
any chance of doing this on an MDM controlled device?

I inherited a FreeBSD box that is forwarding email using Postfix through various JLS (jails).
Two days ago I switched the MX record(s) to point to a third party service that is going to replace this FreeBSD server.
When I log into the FreeBSD machine and look at the logs (specifically to see if mail is flowing), I see two or three messages in a handful of jails.
A week ago before the MX record change there would have been 20 emails every few minutes, so something obviously changed, which was expected.
What was NOT expected was to see ANY mail flow through the FreeBSD machine.
My question is: Should I expect to see some mail for an extended amount of time? I'm asking because I thought that once I changed the MX record - with a TTL of 300 for all 5 priorities - that it would handle all the mail.
Thanks for your help!

No matter what NTP server address i put in it says "server could not be reached". I tried setting it to force and rebooting it but that didnt do anything either. I'm not understanding why this wont work because i can clearly ping from FreeNAS to my other servers that i want to use as a reference.
I also tried doing it through shell but I don't know if I have the commands correct...
