Cannot print to an HP Laserjet 1020 using Terminal Services

by on Jul.22, 2014, under Networking, Windows Info

Terminal Services can only print to your LPT printers (with proper driver installed on the server). In order to print to network printer or USB printer,

1. Install the printer normally (connecting via TCP port or USB port) and make it a shared printer (ie. \\COMPUTERNAME\PRINTER)
2. Install ANOTHER instance of the printer, using the LPT1: (or LPT2:) port
3. Launch an administrative command prompt, and map the LPT port to the shared printer instance:

net use lpt1: \\COMPUTERNAME\PRINTER /persistent:yes

Now, you have an LPT: printer. If you set it as your default printer you can print locally, and Terminal services should now allow you to print from your TS session, as well.

Happy Birthday, Internet!

by on Mar.12, 2014, under Amusement, Networking

On this day in 1989, British computer scientist Tim Berners-Lee presented to CERN management a proposal for a “universal linked information system” called Mesh, meant to help staff at the Swiss research center coordinate their work. Today, what we now know as the World Wide Web turns 25. Berners-Lee gave several interviews for the occasion. Looking back on his creation, he told CNet he’s glad the Web has developed as a “non-national” entity but deplores that most people on the Web still stick to their own cultures and their own ways, using the technology to reinforce their biases rather than open their world:

“I’d like it if developers on the Web could tackle the question of how to make Web sites that actually make us more friendly to people we don’t know so well,” he said.

Public Time Server info

by on Dec.20, 2013, under Computer Stuff, Networking

People are always asking me which time server to use. Here’s the list of time servers hosted by the NIST. You *should* use time.nist.gov, in order to let them round-robin your requests across all of their servers, for load-balancing purposes.

Review time!! Boolean ANDing

by on Oct.08, 2012, under General Info, Networking

A new, wild Nancy beat her husband hard.
ADDRESS – Get IP address 172.32.45.36 = 10101100.00100000.00101101.00100100
NETMASK – Get subnet mask 255.255.248.0 = 11111111.11111111.11111000.00000000 = /21
WILDCARD – Find wildcard mask/bits = 00000000.00000000.00000111.11111111 = 0.0.7.255 (11 bits)
NETWORK – Drop wildcard mask from IP address = 10101100.00100000.00101000.00000000 = 172.32.40.0
BROADCST – Add wildcard to the IP address = 10101100.00100000.00101111.11111111 = 172.32.47.255
HOSTMIN – Drop the wildcard mask, and add 1 = 10101100.00100000.00101000.00000001 = 172.32.40.1
HOSTMAX – Add the wildcard mask, minus 1 = 10101100.00100000.00101111.11111110 = 172.32.47.254
HOSTS/NET – 2*(WILDCARD_BITS)-2 = 2(11)-2 = 2x2x2x2x2x2x2x2x2x2x2 = 2048-2 = 2046
Find hosts per net using the formula 2 to the power of the bits in the wildcard mask, minus 2.

32-bit IPv4 Network Address
Octet1 Octet2 Octet3 Octet4
128|64|32|16|8|4|2|1.128|64|32|16|8|4|2|1.128|64|32|16|8|4|2|1.128|64|32|16|8|4|2|1
11111111 . 11111111 . 11111000 . 00000000 = 255.255.248.0
10101100 . 00100000 . 00101101 . 00100100 = 172.32.45.36

And I’m sorry, but no. I can’t make it ANY simpler than that. ;)

@AuthenticatorTypeId INT,
@AuthenticatorInstanceId INT,
@ExternalAuthenticatorId VARCHAR(255),
@EncryptedPassword VARCHAR(256)

/************************************************************
Start of editing required section

SET @DisplayName = ‘System Administrator’ — Display name (Not always used)
SET @Authentication = ‘BAS’ — ‘BAS’ for BAS authentication
SET @EncryptedPassword = ‘7B7ECF0DAF70D040345D8DD92607E274969F4BA5DFDFAEAC5DE775E5340CDF605D5762EC5D326498ADBE72E7434897025A8702D0237046F554DBCA5769B90154:7637B189’ — Encrypted string of password ‘blackberry’

/************************************************************

IF @Authentication LIKE ‘BAS’
