What is redbrick
---
## Login
How to ssh
----
Does anyone need a redbrick login or password?
----
## Type this in your terminal
`~$ ssh username@redbrick.dcu.ie`
- Your password won't show up for those damn screenlookers
----
---
## Multiplexer
A terminal multiplexer is used so that you can have multiple terminals open but in the one terminal window
----
## The Choice
Tmux vs screen
----
### Tmux
- Lighter than screen (which ~~is shit~~ we don't use)
- Better plugins
- Scriptable
- Already setup, just type `tmux` to get it going
----
### Auto Attach
- nano ~/.zlogin
- add the followin line `tmux attach -d`
---
## IRC Clients
irssi or weechat
----
### Weechat
- Command Line irc client
- Some advantages over irrsi
- Looks nicer
- Easier to install scripts
- alternatives include irssi
----
#### Useful Commands
- /script
- **iset.pl** - nice interface for changing settings
- **screen_away.pl** - sets away status when you detach from screen
- **cmdind.pl** -tells you is its command or message
- **grep** - lets you grep in weechat
- **pushover.pl** - notification center
- Remember to /save when you update settings
- And run /autojoin --run
---
## Webspace
- Open up the FTP Client (Winscp and filezilla)
- Login to
- Host: sftp://redbrick.dcu.ie
- User: RedbrickUsername
- Pass: RedbrickPassword
- Port: 22
----
- Navigate to public_html/ (it's in your home directory)
- Drag and drop your file to upload or select from the filesystem
- SSH into the Redbrick
- In your home directory (~) enter the following commands:
```
cd public_html
chmod 755 .
```
- You would have to create this file first
`chmod 644 index.html`
This sets permissions for the folder and file
---
### SSH Keys
Make ssh easier
----
### Step One
- Create the RSA Key Pair
`keygen -t rsa`
----
### Step Two
```
Enter file in which to save the key (/home/demo/.ssh/id_rsa):
```
You can press enter here just to store in home
```
Enter passphrase (empty for no passphrase):
```
- Set a passphrase for the key
- It's up to you whether you want to use a passphrase.
----
### Step three
- Copy the public key
`ssh-copy-id username@redbrick.dcu.ie`
