SSH try outs for fun
Experiment 1
Question
What is the question you'd like to pose for experimentation? State it here. can you ssh to a system in a home network by server name.
Resources
Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment. -*www.google.com
Hypothesis
Based on what you've read with respect to your original posed question, what do you think will be the result of your experiment (ie an educated guess based on the facts known). This is done before actually performing the experiment.
State your rationale. I belive that while sitting at the main computer. i can log onto my green server by utilizing the ssh command.
Experiment
How are you going to test your hypothesis? What is the structure of your experiment? step 1 sitting - such a relaxing first step
2 unix use command line, windows- putty or such. 3 used ssh command to connect. sucess
Data
Perform your experiment, and collect/document the results here. First two times had no success
- called server with server name.
- Ip address of the main computer(@ 4am )
Analysis
Based on the data collected:the [osibilities of conectting thr multitpule tunnles via ssh could be infinit
- Was your hypothesis correct?
- Was your hypothesis not applicable?
- Is there more going on than you originally thought? (shortcomings in hypothesis)
- What shortcomings might there be in your experiment?
- What shortcomings might there be in your data?
Conclusions
What can you ascertain based on the experiment performed and data collected? Document your findings here; make a statement as to any discoveries you've made.
====Experiment 2====installing driver
Question
What is the question you'd like to pose for experimentation? State it here. if the usb stick used to install ubuntu holds no grub loader. can it be installed via other card.
Resources
harddrive - from old computer. usbcard poccessing enough mem space for ubuntu 10.04
Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment.
Hypothesis
by reinstalling ubuntu srever to a new assinged computer. One can etemp to install the grub bootloader onto the non-bootable drive.
State your rationale.
Experiment
How are you going to test your hypothesis? What is the structure of 1 wipe a SD card clean of any privous information. 2 Threw (installed) ubuntu 10.04 iso. on card. 3 inserted card into usb port on blink machine. 4 started and intialized boot to sd within bios of motherboard. 5 reinstall boot loader
Data
-sd wipe- success iso installation- success boot to sd - success grub bootloader- fail.
Analysis
The drive sleected for the installation may be one of the issuse faced here. The chosen procedure is a simple and easy way of handling a boot issue. yet more knowledge on installation error contingency planning must be done.
Based on the data collected: based on the experiment the hypothesis wolud have been successful if not for hard drive malfunction. it is a highly use meathod.
Conclusions
