I built my new Home 'Backup Server' last year and never got around to moving over the Two ( full of Data !) 2T hard drives 'Raid 1' Mirror from the old server to the new one. My old Backup server only had Two x 2T 'Raid 1' Mirror drives but the new one I have 3 pairs of 2T drives in 'Raid 1' Mirror, Raid set 1, Raid set 2, Raid set 3. I am using 'mdadm' software Raid. I want to replace the Raid set 1 (No Data on them ) drives on the new server with the old ones. What is the correct way to do it with out loosing any data.

Building A New Home Backup Server/Store. Since my 5 year old backup NAS is full 2 x2TB drives, and the desktop pent III is getting old now (some bulging capacitors !) I bought a new 10 drive bay space case ( with more capacity ), and 4 new 2TB drives. PS and Gigabyte GA-H170M-DS3H MB with 6 x SATA ports. I will use my two old 2TB dives out of my old unit and another SATA HD for the PCLinuxOS Darkstar OS to run it. I want to set this machine up with 6 x 2TB 3.5" hard drives for now, Then using two raid cards have spare capacity for expansion if needed. Three Raid sets all 'Raid 1' Mirror. Raid set 1 = (my two old hard drives ) SATA port 0 & 1 on the MB (not fitted yet !). Raid set 2 = 2x2TB drives SATA port 2 & 3 Raid set 3 = 2 x 2TB drives Sata ports 4 & 5 I have got in to the MB Raid set up screen and can see the four 2TB drives, set up Raid set 2 ok using ports 2&3 , but then trying to set another raid set 3 up with Raid 1 mirror it will not let me set it up. Any ideas why ?. Can you normally set up more than one mirror raid set on a motherboard ?. or Should I just forget the MB raid set up and use Mdadm ?.

Have You Checked Your Firewall Logs Lately ?. I am seeing in my Home Hardware Firewall (Smoothwall SWE3.1) hundreds/ thousands of hits on Port 23(TELNET) some on 2323 and 22 I have page after page of logs that show the hits are getting more and more each day. :'( This is the MIRAI and its variants (MEMES being one of those) Malware. My firewall is working overtime but doing a good job. Anyone else seeing anything ?.

Thanks for feedback. @ elsiegee40 PM Sent . The facts as I know them, while I was visiting her last week I looked at her laptop network settings, using DHCP to the firms LAN IP = 10.255.156.223, Gateway of 10.255.156.1 DNS 10.255.156.2 Netmask 255.255.255.0 I could see there feed comes through a 'pfsence' Hardware Firewall. Checking her laptops Network IP address / Gateway and DNS settings I noticed the DNS and Gateway where different and it looks like it's DNS server is the the mail server for this firm ! I did try to view the Gateway IP address in a web browser and it seems to bring a 'ThisFirm's web page up. I then did the same with the DNS IP address and got a 'login' page for there internal mail server It looks like there server has lots of services running on the same server, DNS, email hosting etc... and all using the same external IP address, as they use different ports . It is the external IP address has an rdns of mail,thisfirm.url The website for the firm and all there Ethernet LAN is handled via another IT. . I can access the laptop via 'Teamviewer' from home to do maintenance . Because our home ISP = Eclipse (Kcom) she cannot use there SMTP mail servers on port 25 as she does at home, I have set it up to use SMTP.gmail.com port 587 for the outgoing mail server, this has worked well while she was at uni and other courses for the last 5 years. On her laptop I have an automatic back up system (using 'Luckybackup') to my server at home and that sends me an email using 'sendEmail' via the command line (Linux Terminal ), looking at one of them at the headers/source code I can also see the rDNS company name on that as well. re. 'I would use postfix to strip out internal server names from headers' not sure what post fix is. !.

You can still view email headers on iphone which she uses.

I think the use of unauthorized VPN are not permitted !. A VPN to where ?

Is There A Way To Hide A Domain Name In A Private Email ( not the firms Emails ! ) Message Headers/Source Code. ? My daughter has started a new job and gets free accommodation with it and free internet which is run off the sites main domain server on a separate .net LAN which I would think does admin offices and shops and other staff accommodation etc. On a test private email she sent me to our home, looking at a email message header/source code I can see one section says ' Received: from localhost.localdomain (mail.domain name of firm.net. [xxx.xx.xxx.188]) ' >>>>>Name of firm and it's IP address removed !<<<<< It looks like this internet facing IP address for the firm has rDNS, using 'Whois' gives the location etc. It's telling the world (if you know how to view an email header !) where she works and worse still where she lives, which nowadays for a young lady living alone is not a good idea. A email test using a web mail Does not show the firms name or IP address eg Gmail, she uses 'Thunderbird' mail browser on a 'PCLinuxOS' run Laptop. The flat is served by a (locked) WiFi access point from the local LAN . If I set her a separate access point / LAN for her flat could it be configured to hide the firms name on the emails sent ?.

I have a AP6522 Access Point for use at home / garden. 1..Does anyone know if you have to use all four aerials ? 2...Is one aerial transmit and the other receive on one radio ? 3.. What 'telnet' command do I use to change the radio channels ?

Are you talking about the access point works well ?. Did you use coax cable with it ?.

I've now got a Motorola-AP6522 and 4 outside/inside aerials, POE. Extreme ML-2452-HPA5-036 - Antenna outdoor 2G5G3dB Omni http://www.thebarcodewarehouse.co.uk/Assets/Documents/Motorola/Motorola-AP6522-Datasheet.pdf Does anyone know how much coax I could use for the aerials before I get bad attenuation of the signal ?

I have a old WRT54GS (Router) that I used for an internal Ethernet cable fed 'WiFi access point' only, it has Two removable aerials and I was thinking of using one, waterproof it and mounting it on my outside gable mounted TV and FM aerial mast, The top of the mast is about 2 metre above the ridge, mounting the WRT54GS in side and using some coax cable to connect the two. I want to improve the WiFi coverage all over my large garden as it has one or two dead area's at the moment. With the Bipolar aerial it should radiate to all my garden as the house is in the center of the half acre garden. Will it work ?

I spent more time on this today. The problem seems to be the part of first cable that I put in 20 years ago to my garage (about 40 metre's long) which turns out to be 4 core screened to 'Def 10' standard, it was never intended for Ethernet but it was worth a try. I tried sending internet down it but it was very poor, so even with another switch there it did not stand much chance of sending Ethernet to my workshop. The cable route to my garage and workshop is now converted for telephones use and works very well for that. Thank you all for your help.

1. Have I got the pins right ?. 2. Would anther switch at 25 Metre's help ?. 3. Even if the cable was too long / not the correct type would the three lights on the on the switch light ?.

Ethernet Cable From House To Workshop, will not work. I have used some Ex BT SWA underground (Drop-wire that was left after BT man did not take it away some years ago) , It's two twisted pair and I have used a short piece of Ethernet cable 2000mm long to join on to it at the house end and it has a RJ45 socket at the other. House to Workshop Ethernet cable to RJ45 socket Pair one Pin1 Pin 1 Pin 2 Pin 2 Pair two Pin 3 Pin 3 Pin 6 Pin 6 It's about 150 Metre long. Plugging the house end in to a Switch No lights show up, plugging the workshop end in to either another switch or my laptop do not connect.! I have tested the cable for continuity with an test meter (Each core = 5.6 ohms that's by shorting out one end to the SWA and using a test meter at the other SWA to core being tested.) Also test for insulation between each conductor also to SWA all ok. What am I doing wrong ? Why does it not work ?.
