All serious jailbreakers know that SSHing is an essential.
Here is a little walkthrough on how to install OpenSSH:
- Open Cydia and scroll down the main page to where it says “OpenSSH Access How-To.” Tap that option.
- On that page, click the blue linked text “Open SSH” in the first step. You’ll be presented with the OpenSSH package page. Click the install button in the top right corner, confirm when it’s finished, and return to Cydia.
- Open the Settings app from your home screen and go into your Wi-Fi settings. Click the little blue arrow next to the Wi-Fi network you’re currently connected to. Make a note of your IP address in the “IP Address” field (it should start with 10 or 192).
- To connect to your iOS device from your computer, use an SSH-capable application like Terminal on OS X or puTTy on Windows. Type
ssh root@YOUR_IP_ADDRESS(replacing YOUR_IP_ADDRESS with your actual IP address). When prompted, enter your password. It’s alpine by default. Once finished, you’re connected! You can also use an SFTP application like Cyberduck to connect as well, but that’ll limit your interactions to pretty much only file transfers.
- Lastly, you want to change your password. To do this, type the passwd command. You’ll be asked for a new password. Type it (nothing will show up for privacy reasons) and press enter. Type it in again to confirm it. Assuming you type your password correctly, you will be told it was changed successfully.
That’s it! Enjoy SSH’ing with your iOS device.
IMPORTANT:
Make absolutely certain that you alter the password of the mobile account! As mentioned above, by default it is “alpine”, but until the root and the mobile account passwords are changed, your phone is at high risk!

Here are the exact words from The Dev Team Concerning iTunes 8.2 and other informative updates:
Yesterday, Apple started pushing out their official iTunes 8.2, which supports mobile devices at firmware 3.0. Here’s why you jailbreakers and yellowsn0w-users shouldn’t really accept that “Update now?” question:
•Most people aren’t at 3.0. In fact 3.0 is still in beta and has lots of bugs (especially related to push updates).
•It breaks your ability to use QuickPwn, PwnageTool, and iPhone Tunneling Suite (ssh over usb). We don’t think this is a deliberate breakage of these tools. It’s just that Apple has updated a low-level USB protocol that normally only Apple cares about (but jailbreakers care about).
•So far, the only appreciable change to iTunes 8.2 is the Genius function working on videos.
•It may actually break Palm Pre’s connection to the device (please give us feedback on this).
This update is one of those that incidentally breaks QuickPwn and PwnageTool. It doesn’t seem like an anti-jailbreak. But nonetheless, it will break your ability to re-run QuickPwn or PwnageTool’s dfu-entry.
Because this update isn’t a deliberate anti-jailbreak measure, it’s easily fixed in our tools. But we really don’t want to update our tools until 3.0 is out, so please don’t update to 8.2 if you think you’ll need to rejailbreak your device. 
YellowSn0w on 2.2.1 and beyond
We see many questions about whether yellowsn0w can ever be made to work on firmware versions past 2.2 (or equivalently, basebands past 02.28). This is probably a good place to address those questions:
If there is a yellowsn0w update for firmware after 2.2 (or basebands after 02.28), there is no way it would ever be released before 3.0 is official. It just wouldn’t make any sense to release an exploit for something that only those who have beta 3.0’s (NDA signers) could use. Most people in the world aren’t NDA signers. Any yellowsn0w update for 3.0 would need to happen *after* 3.0 is officially available

SSH’ing is a useful skill to know. It can help get apps to work, enable you to create custom backgrounds and icon images, copy content directly from your iPod, and so much more. Once you get used to the navigation, it is quite easy and will help you become a better hacker. Now, onto the steps.
1. What You Need
- A jailbroken iPod (read my previous posts on how to get your iPod jailbroken)
- In Settings, click general, auto-lock, never
- Make sure you have WiFi and a computer or this will not work
2. Install OpenSSH on your iPod
- In installer, go to install, all packages, OpenSSH
3. Download and install WinSCP
4. Enter your information
- To find your host name, turn on your iPod and go to settings, WiFi.
- On your selected network, click the blue arrow on the right
- The IP Address is your host name, type it in the box in WinSCP
- The Username is root
- The Password is alpine
- Click Login
- It will take awhile on your first try
- Always keep searching and waiting until it is found
- When the warning comes up, click Yes
- You are now inside your iPod
5. What to do now
- I know this is going to bug a lot of you, but I am not going to tell you what to do yet
- Keep reading the site to see what you actually did this and why it is extremely useful
- I guess you will have to keep coming back to the site to check for updates (which will be soon)
- Note: Don’t mess around with the fies you now are capable to edit. It could damage your hardware
