19inch.net)Nineteen Inch ("19inch") is Paul Sladen's consultancy and also provides various web hosting, DNS, e-mail services, shell access, vservers and other ISP-type services on a few Debian GNU/Linux boxes: hutch, starsky, columbo and some others in Nottingham and London.
If you get stuck, contact Paul Sladen by telephone
(0115 922 7162) or email sladen+www@19inch.net (prefered).
If you think the name is a bit strange; the standard size for [rack-mounted] computer and telecoms equipment is nineteen inches wide.
The dialup number is
0845 079 5652
which is Lo-call rate.
(If you have a shell account or dedicated/virtual server, you can logon
with username@yourserver, allowing you or your
customers to use dialup access with the same details as you would use
for normal POP3/FTP details.
This number support 56Kb V.90, single and bonded dual ISDN.
Domains hosted with 19inch, or which have DNS hosting through 19inch should be set to use the following (DNS) nameservers:
| DNS Nameserver | IP address (shouldn't be required) | Location |
|---|---|---|
starsky.19inch.net
[1] |
80.1.73.116 |
Nottingham, at Flexeprint |
jasmine.wyrdweb.com |
194.153.168.126 |
Telehouse London, Jump Networks |
janeway.hambule.co.uk |
195.177.252.77 |
Finchley, London, at Demon |
[1] people
with a shell accounts on muse, who are also managing
their own DNS on should replace starsky.19inch.net.
with muse.19inch.net. as the primary nameserver.
Having three DNS servers across three physically diverse
networks, and under three seperate TLDs providers an extra degree
of stability. In the event that both starsky and
jasmine were to be unavailable owing to maintenance
or dual failure, the externally managed box at Demon
(janeway, run by Tom Bird) would still be able to
supply backup MX records to ensure that email
continues to flow to the true extend that it can.
This represents a considerable improvement over most ISPs who place both/all of their nameservers on consecutive IP addresses directly connected to the same network, and often the same switch/hub in the same building. If Internet access is lost to thet building, or a piece of networking hardware fails, even the information that describes backup/alternate services cannot be fetched. (eg. Diverting mail to MX backup servers).
To save you typing out all our details, the companies running the top level .com/.org/.net domains use shortcuts called NIC Handles to store all our details in one nice easy one that can be changed and updated in one go.

everything currently maps to the same place.)

Generally you should use your own Dialup/Broadband ISP's SMTP server which is restricted their particular customers, generally by IP address/network. Suspect you knew that already; but since I'm OK as long as people authenticate themselves somehow I've setup a few extras:
| Service | Server | Port (default, standard ports) |
|---|---|---|
| Plain SMTP | {Your Dialup provider's mail server} | Port 25 |
| Authenicated SSL SMTP | smtp.19inch.net |
Port 465 |
| Authenicated SMTP | smtp.19inch.net |
Port 25 |
| Pop-before-SMTP [2] | pop3.19inch.net |
Port 25 |
[2] This method does not use any extra authenication for *sending* using SMTP, A successful login via POP3 to fetch-down or check your mail is regarded as enough to allow you to temporarily send mail regardless. This is done by adding your IP address to the list of hosts allowed to use us as a "Smarthost" for a period of 5 minutes. Your mail software should therefore be configure to check for mail before trying to send outgoing emails to our servers.
(Forget the silly SPA `Secure Password Authenication', that's dogey and requires saving plain-text copies of passwords on the server--not good.)
Websites have moved around, mostly on hutch now:
FTP upload ftp://username:passwd@ftp.yourdomain.co.uk Website http://www.yourdomain.co.uk Usage statistics http://www.yourdomain.co.uk/usage
We do not allow, or enable the Telnet protocol on any of our servers as it is insecure and transmits passwords in plain-text.
If you have a shell account on one of our servers, you will need to login using SSH (Unix Secure SHell) which provides for encyption of all data, including your passwords and most critically your login client.
PuTTY is a very good client for Win32 Windows systems (Win95
and WinNT upwards). The program is distributed with a companion
called pscp (Putty Secure CoPy) which is a Win32
console (you need to run it from one of them `DOS Box'
things) version of the Unix scp; you could even
rename it to scp is you wished.
Niftytelnet
and MacSSH
and good SSH programs for the Apple Macintosh. MacOS X is
built ontop of Unix and has SSH natively built in, to use it,
select a console and type
ssh user@hostname.com.
OpenSSH, or a commerical
version of SSH is probably installed on most Unices/GNU-Linux
machines already; and chances are you're already using it if you
use Unix! ;-). To
install SSH onto a Debian GNU/Linux system, simply type:
apt-get install ssh
Mindterm is a Java SSH client that can be useful if you are stuck in a CyberCafé and are unable to run a native SSH client. You should download and run it on your own server. (An embedded webpage can be found at muse.19inch.net/mindterm/.
SSH has the ability to do loads of magic on top of when you have logged into a remote machine (the `screen' from the remote computer will come up on your Desktop even though it is many miles away across the Interweb). One of the these features is to automatically compress the data going between you and the remote machine. We typically see 10:1 compression from the remote computer to you.
Payments should be paid in pounds sterling, electronically via bank transfer (BACS/CHAPS) or standing order. Cheques will only be accepted when they include an additional £20.00 processing fee:

Sometimes we may need access to your dedicated or virtual-server; to enable this to happen safely, SSH needs to be setup on your server so we can gain access using SSH keys (this means that we don't have to know any of your passwords, or root passwords).
SSH is normally setup so that you can't log straight into
root using SSH without first needing to login as a
normal user and then using `su', or
`sudo' to perform root commands. Access can be
enabled for particular keys by setting the following line in
`/etc/ssh/sshd_config' which allows for login with
SSH keys, but you will still be refused if you're trying to login
using a root password.
PermitRootLogin without-password
Remember that we still have to type a password to unlock our half
of the keys to enable us to login. To allow root login by our
keys you should copy the contents of hostmaster-19inch-net.pub.txt
into the file `/root/.ssh/authorized_keys on your
server.
To check that these keys have not been tampered with, a copy of
the fingerprints of the keys above has been signed with
Paul Sladen's personal
GPG/PGP key (0xe90cfa24). Please check the file hostmaster-19inch-net.asc.txt.
