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

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.img bs=1G count=5 There I get up to 106 MBps and then I guess I'm hitting the 1 Gbps Ethernet connection speed limit.

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
         

Excel chart generation enabled
        Record Size 4 kB
        File size set to 10485760 kB
        Command line used: iozone -i 0 -R -l 5 -u 5 -r 4k -s 10G
        Output is in kBytes/sec
        Time Resolution = 0.000001 seconds.
        Processor cache size set to 1024 kBytes.
        Processor cache line size set to 32 bytes.
        File stride size set to 17 * record size.
        Min process = 5
        Max process = 5
        Throughput test with 5 processes
        Each process writes a 10485760 kByte file in 4 kByte records

        Children see throughput

Hello ,

We need to install eth-tool on freebsd. As far as i searched on the net it is not possible but i am very suprised to see this on free bsd man's page

Hello ,

I am using intel X550 fiber interface but it has unsupported SFP+ modules so i need to apply this command on freebsd   :
modprobe ixgbe allow_unsupported_sfp=1,1


Thank you

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 ?

iptables -t raw -D PREROUTING -p tcp   -m tcpmss --mss 1460  -m ttl --ttl-eq=118 -m length --length 48  -d 178.20.227.138   -m u32 --u32 '32&0x0000FFFF=0x2000'  -j DROP 

iptables -I FORWARD 1 -i p4p2 -m ttl --ttl-eq=252 -m length --length 1048 -d 185.9.157.211 --match string --algo kmp --hex-string |000000000000000000000000000000000000000000000000000000000000| -j DROP

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:

Detail: Invalid response from

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

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 have a mail server on a FreeBSD box. Can you tell me how to tell what kind of email server is running on this FreeBSD?

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...

I know that I can organize a single directory listing with:

LS -LTR

How would I look for all .php files on the whole drive, with the latest being at the bottom?

Any ideas?

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.

I'm trying to figure out what the very top (dot) directory is, and why it shows that it was created today.

I'm having trouble getting FTP to work on our server.

When I check auth.log it contains:

Jul  5 13:06:29 216-55-xxx-xxx sshd[57421]: Accepted password for ftpuser from 67.177.xxx.xxx port 58996 ssh2
Jul  5 13:06:29 216-55-xxx-xxx sshd[57423]: subsystem request for sftp by user ftpuser failed, subsystem not found

Any ideas?  It's been a LONG time since I configured this server.
