# I get a permission denied when trying to SSH
Unfortunately SHA-2 RSA keys are not currently supported.
Unfortunately, due to a shortcoming in Go’s x/crypto/ssh package, we do not currently support access via new SSH RSA keys: only the old SHA-1 ones will work. Until we sort this out you’ll either need an SHA-1 RSA key or a key with another algorithm, e.g. Ed25519. Not sure what type of keys you have? You can check with the following:
$ find ~/.ssh/id_*.pub -exec ssh-keygen -l -f {} \;
If you’re curious about the inner workings of this problem have a look at:
# Generating a new SSH key
ssh-keygen -t ed25519 -C "your_email@example.com"
- When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.
- At the prompt, type a secure passphrase.
# How do I update a post?
Updating a post requires that you update the source document and then run the scp
command again. If the filename remains the same, then the post will be updated.
# How do I delete a post?
Because scp does not natively support deleting files, I didn't want to bake
that behavior into my ssh server.
However, if a user wants to delete a post they can delete the contents of the file and
then upload it to our server. If the file contains 0 bytes, we will remove the post.
For example, if you want to delete delete.txt you could:
cp /dev/null delete.txt scp ./delete.txt pastes.sh:/
Alternatively, you can go to ssh pastes.sh and select "Manage posts."
Then you can highlight the post you want to delete and then press "X." It will ask for
confirmation before actually removing the post.
# When I want to publish a new post, do I have to upload all posts everytime?
Nope! Just scp the file you want to publish. For example, if you created
a new post called taco-tuesday.md then you would publish it like this:
scp ./taco-tuesday.md pastes.sh:
# Can I create multiple accounts?
Yes! You can either a) create a new keypair and use that for authentication
or b) use the same keypair and ssh into our CMS using our special username
ssh new@pastes.sh.
Please note that if you use the same keypair for multiple accounts, you will need to always specify the user when logging into our CMS.
# Can I pipe my paste?
Yes!
echo "foobar" | ssh pastes.sh
echo "foobar" | ssh pastes.sh FILENAME
# if the tty warning annoys you echo "foobar" | ssh -T pastes.sh
