mac OSX version 10.11.3
Astana studio build: 3.6.1.201410201044

i get this error whenever I try to connect to an SFTP server using an SSH key that has already been setup (and tested through the terminal application). i tried unchecking the "Use public key authentication" box (under properties for the SFTP server) but when i save and reopen properties, it just goes back to what it was set to before...

i just tried creating a test sftp connection with just a regular password, no ssh key and it gave me the same error, so i don't think its an ssh key issue...

Aptana only carries support for 1 (?) cipher, the diffie-hellman one. Most SSH servers don't support this cipher anymore.

I'm wondering about this as well. I'm no longer able to connect to some remote systems as those old ciphers are obsolete and have security patches have disabled them on many machines. Will this ever be fixed, or is Aptana basically an abandoned project, and we need to look for a different IDE?

Im using the synapse plugin for Sftp access to my website...

I've used aptana for years, since v2.something. I really liked it... until this broke it for me.

I'm not going to re-introduce outdated, insecure KEX protocols to my webservers just because the sFTP / ssh libs can't be updated in the IDE.

Sad to see you go, Aptana but I guess it's time for a full-time switch to Atom.

i have tried what user vasc0x sugested, but didn' t worked for me... then I deleted /home/federico/.ssh/known_host file, and stablished an sftp connection from the terminal : sftp user@host . it created the file again... then i could connect to my server in aptana correctly... i do not recomend you to do what i did... you may loose other server keys... buy they easily can be recover doing sftp from the terminal when prompted
The authenticity of host '[XXX]' can't be established.
ECDSA key fingerprint is XX:XX:XX...
Are you sure you want to continue connecting (yes/no)?
answering yes....

Hey @vasc0x - It worked like a charm. Can you tell me what it does exactly?
