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.

Hi,

I'm currently running Solaris and need to convert the following syntax from FreeBSD Gpart to Solaris Format.  I know Solaris has Gpart as well but will this format work on Solaris or does it have to be converted?  Also to note I'm not a Solaris, Linux, Red Hat, guru so please write out exactly what the syntax is or in detail how to go about this.  Also if someone could reference an article or let me know what the following means "-s  ,   -b   ,    -l    ,    -a  "

gpart create -s gpt disk1
gpart create -s gpt disk2

gpart add -t freebsd-zfs -b 2048 -a 4k -l log0 -s 500MB disk1
gpart add -t freebsd-zfs -b 2048 -a 4k -l log1 -s 500MB disk2

gpart add -t freebsd-zfs -a 4k -l cache0 disk1
gpart add -t freebsd-zfs -a 4k -l cache1 disk2

zpool add LumiPool log mirror gpt/log0 gpt/log1
zpool add LumiPool cache gpt/cache0 gpt/cache1

Thanks

Important Lessons on Recovering from Petya

In their most recent webinar, Skyport Systems explores ways to isolate and protect critical databases to keep the core of your company safe from harm.

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

Hi
I am trying to make Squid working on FreeBSD 11
I have two NIC's internal INT_IF and external EXT_IF.

My NAT is working but I am not sure if this is redirection issue or squid.conf

--- /etc/pf.conf
nat on $EXT_IF from !($EXT_IF)->($EXT_IF:0)
rdr on $INT_IF inet proto tcp from any to any port www -> 127.0.0.1 port 3128

pass in  on $INT_IF inet proto tcp from any to 127.0.0.1 port 3128 keep state
pass out on $EXT_IF inet proto tcp from any to any port www keep state


pass in quick on { lo0 $INT_IF } all
pass out quick on $EXT_IF inet proto {tcp,udp} from any to any keep state

pass out quick on $EXT_IF inet proto { tcp,udp,icmp} all

I'm trying to configure my server firewall to only accept connections that are coming from an Xfinity user.  I don't have a static IP, but was wondering if Xfinity owned a block, or something like that.

I'm setting this up on a FreeBSD server.

Just got word that there has been "suspicious activity" on my server.  It has something to do with the file mysite.com/.mail

Can someone help me lock things up?

I've changed my root password so far.

I'm wondering if a NUC of type DCCP847DYE would be easily expandable for storage (NAS) purposes. 'Unboxing' shows a SATA socket (see attached)
