| − | The sensor nodes we have ordered are from Crossbow technology ([http://web.archive.org/web/20071012145715/http://www.xbow.com/Products/productdetails.aspx?sid=264 http://www.xbow.com/Products/productdetails.aspx?sid=264]) |
||
| + | If the documentation is correct, it looks like I'm getting the old fingerprints while the server should be using the new ones... |
||
| − | Basically, the sensors operate in 2.4GHz ISM band. The range of the radio module is about up to 50 m indoor and up to 300 m outdoor. |

||
| − | The PacketParrot application which is provided with TinyOS does not work on directly on the Iris motes. Thus, the following modified version can be used instead. The modifications are basically replacing the special radio component, which is used for sending and receiving, by the generic AMSenderC and AMReceiverC components. |

||
| − | cd Downloads |

When trying to connect to
shell.stud.informatik.uni-goettingen.de
via ssh, it tells me that the fingerprint is
SHA256:L+FCMj2bm8x/BfR8AdaaLnqTmFD35D0EYNlFG7a2dt8,
which is documented here to be the old fingerprint, so it should only have been in use till april 2017.
So, is the documentation incorrect or is the shell server still using the older fingerprint (at least sometimes)?

shell server fingerprints
Also, the fingerprints for ssh-ed25519 is the same on shell.informatik.uni-goettingen.de and shell.stud.informatik.uni-goettingen.de, but does not match any of the fingerprints documented. I get the following fingerprint: SHA256:H4FLNG2aNYRZ3jxepIx5E0s0a2ZvtZbbmVLt56b+nK0. What is the correct fingerprint? If the documentation is correct, it looks like I'm getting the old fingerprints while the server should be using the new ones...
