Welcome to the Mirror Services infrastruction site by BOINC Team Belgium. On here, you will find software mirrors of various Linux® and UNIX®-like operating systems distributions. The mirrors sync once an hour (or once per 2 hours for ISO mirros) using rsync with a Tier 0 or Tier 1 mirror
You can check the installation date of a FreeBSD server by looking at the /var/log/bsdinstall_log file, which typically contains a line indicating when the installation began.
Alternatively, you can use the command stat -f '%SB %N' / to see when the root filesystem was created, but this may not reflect the actual installation date if the system was modified later.
In tcsh, you can do:
(ls $argv > filelist) >& /dev/nullNote that >& redirects both stdout and stderr, but since stdout has already been redirected elsewhere only the stderr will make it through to /dev/null
Check Listening Ports with netstat
netstat is a command-line tool that can provide information about network connections.
To list all TCP or UDP ports that are being listened on, including the services using the ports and the socket status use the following command:
sudo netstat -tunlpThe options used in this command have the following meaning:
-t - Show TCP ports.
-u - Show UDP ports.
-n - Show numerical addresses instead of resolving hosts.
-l - Show only listening ports.
-p - Show the PID and name of the listener’s process. This information is shown only if you run the command as root or sudo user.
To check the CPU temperature on FreeBSD, you can use the command sysctl -a | grep temperature after loading the appropriate driver for your CPU type with kldload coretemp for Intel or kldload amdtemp for AMD processors. Make sure to add the driver to /boot/loader.conf for automatic loading at boot time.
You can list devices on FreeBSD using commands like geom disk list, camcontrol devlist, orgpart show to display information about the disks and their partitions.
geom part list shows the partitions in FreeBSD. Similarly geom md list will get you the "memory disk" devices
You can list devices on FreeBSD using commands like geom disk list, camcontrol devlist, or gpart show to display information about the disks and their partitions.
- The Linux screen command is a versatile tool that allows you to run terminal applications in the background and switch back to them when needed.
- It supports split-screen displays and can be used over SSH connections, even after disconnecting and reconnecting.
- With screen, you can create new windows, run multiple processes, detach and reattach sessions, and share sessions between multiple users in real-time.
With the Linux screen command, you can push running terminal applications to the background and pull them forward when you want to see them. It also supports split-screen displays and works over SSH connections, even after you disconnect and reconnect!
Here is another reverse lookups done using dig command:
$ dig -x ip-address-here
$ dig -x 75.126.153.206FreeBSD uses try the drill command:
drill -Qx 54.184.50.208Any number of unwanted or troublesome behaviours may ensue.

Depending on the context of an error, it's not unusual for an operating system halt to fail in response to shutdown -p now.

Ideally: things should be more graceful.
Realistically: it's sometimes necessary to force off the power.

I want to use a live USB iso of FreeBSD to mount my actual system ans change a config file.
My problem is, I can't mount it because I get an error thay says that the filesystem is "read only" (reffing to the ISO filesystem).
Is there another way to do it? Can I make the filesystem read-write?

Create a mount point under /tmp/, mount the file system there. /tmp is a tmpfs and rw.
Something broke. The VPS would not boot:
ZFS: out of temporary buffer spaceSo this sounds like a missing step in the automated upgrade flow. Normally, using new features in zpool is deferred until you choose to upgrade the pool after the reboot, so you get to see the warnings. At a guess (because I'm on FreeBSD 11.4 still), the OpenZFS migration forces the issue to do the zpool upgrade early and they missed the gpart requirement. //
boot from the current rescue disk
bring ifaces up
scp a current/13 zfsbootcode file
install that
//
gpart bootcode -p /root/Downloads/gptzfsboot -i<gpart index of freebsd-boot> <block device>
with that just use the correct path from gptzfsboot
or just dd if=/root/Downloads/gptzfsboot of=/dev/vtbd0p1 if you are brave
zfs: out of temporary buffer space
posted in: computer | 0
system: FreeBSD v13.0-p7
reason: the bootloader is broken (e.g. after update)
solution: reinstall the bootloader(s) to your boot disk(s)
- Boot from recent FreeBSD image
- find out the devicenames and boot partition number from your boot-disks
gpart show
(the partition named “freebsd-boot” is the boot partition on every disk) - reinstall the pMBR and GPT ZFS bootloader (for every booting disk)
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i <boot-partition-number> <devicename>
(e.g.gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0)
(e.g.gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1) - reboot

Task: View / Display FreeBSD Routing Table
Use the netstat command with -r option as follows:
$ netstat -r
$ netstat -rnHow do I save routing information to a configuration file?
If you reboot FreeBSD box, the routing configuration will be lost i.e. the routing information will not persist. You need to edit /etc/rc.conf file to set defaultroute:
# vi /etc/rc.confSet default route by editing defaultrouter variable:
defaultrouter="192.168.1.254"How about using FreeBSD as an Enterprise Storage solution on real hardware? This where FreeBSD shines with all its storage features ZFS included.
Today I will show you how I have built so called Enterprise Storage based on FreeBSD system along with more then 1 PB (Petabyte) of raw capacity. //
There are 4U servers with 90-100 3.5″ drive slots which will allow you to pack 1260-1400 Terabytes of data (with 14 TB drives). Examples of such systems are:
I would use the first one – the TYAN FA100 for short name.
The build has following specifications.
2 x 10-Core Intel Xeon Silver 4114 CPU @ 2.20GHz
4 x 32 GB RAM DDR4 (128 GB Total)
2 x Intel SSD DC S3500 240 GB (System)
90 x Toshiba HDD MN07ACA12TE 12 TB (Data)
2 x Broadcom SAS3008 Controller
2 x Intel X710 DA-2 10GE Card
2 x Power Supply
Price of the whole system is about $65 000 – drives included.
From time to time, security issues are found within software. The FreeBSD package management system relies upon pkg-audit and the Vulnerability database to alert system administrators that attention is required.
WireGuard is an open-source modern VPN (Virtual Private Network) solution that utilizes cryptography protocols to create secure network connections between devices. It's efficient and offers improved reliability than traditional VPN protocols like IPSec. This guide explains how to install WireGuard VPN on a FreeBSD 14.0 and securely configure network tunnels on the server.
