# Tab Sorcery

A helpful script for simplifying connections to servers and devices on your network.

----------------------
## Shell Setup
Add the script as a source file in your shell prompt, such as a line similar to this:

```
. $HOME/git/tab-sorcery/tab-sorcery.sh example.com 127.0.0.1 bob.user
```

Arguments are:
```
Scan Domain (example.com)
Nameserver address (127.0.0.1)
Default username (bob.user)
```

Once done, all hostnames in the DNS zone should be available for SSH/Telnet/RDP by a tab-completable alias of just the hostname (in new shell sessions).

#### Can I change the window geometry for rdesktop?
Yes! You simply need to export a variable *before* calling the tab-sorcery.sh script. The variable to export is called **SORC_GEOM_RDP**, which will take the form of [width]x[height].
Example:
```
export SORC_GEOM_RDP='1280x720'
. $HOME/git/tab-sorcery/tab-sorcery.sh example.com 127.0.0.1 bob.user
```
The default window geometry that is used if this variable is either unset, or if an invalid value is detected is **1600x900**.

## DNS Setup
You'll likely want to create a DNS zone specifically for this script for better control over the hosts included. I would recommend using a TLD not normally available, to be sure you don't have any overlap with existing DNS names. This domain doesn't need to be publicly queried, and actually it's probably in interest of security if it isn't.

The best way to explain the zone set up is by example. Let's assume you create the zone "**not-a-real.lan**" and you have 5 hosts, known as *host1.not-a-real.lan* through *host5.not-a-real.lan*.
If you create the following entries (BIND format shown):
```
$ORIGIN not-a-real.lan.

host1		IN	A	10.0.0.1
host2		IN	A	10.0.0.2
host3		IN	A	10.0.0.3
host3		IN	TXT	"cisco"
host4		IN	A	10.0.0.4
host4		IN	TXT	"windows"
host5		IN	A	10.0.0.5
```

#### How will this work on the client?
In this case, the script will create aliases called *host1* through *host5*.

Hosts 1, 2, and 5 will connect with, for example, `ssh -t your.username@10.0.0.1`

The `host3` alias is tagged with a TXT record for cisco, so it will be: `telnet 10.0.0.3`

`host5` is tagged as a Windows host, so it will use: `rdesktop -g 1600x900 -u your.username 10.0.0.5`
