svn-ssh under ubuntu

Question

I use putty+pageant on Windows to be able to access the svn server by using ssh. I have my private key that works.

I'm now trying to use the same key on a Ubuntu VM.

I used the .p12 key in Firefox and it works well.

The problem is I can't use svn. I tried to follow the istructions that I found in several places on internet but it did not work.

The problem is that I don't know whether I did everything correctly.

I'm using a .p12 file format for the private key.

I renamed the key as identity and I copied it in the .ssh folder for my account. I also changed the /etc/ssh/ssh_config file uncommenting the line:

IdentityFile ~/.ssh/identity

I used the command:

svn co svn+ssh://myusername@path_to_rep

The result is still

svn: Network connection closed unexpectedly

I removed the -q option in the [tunnel] section of the subversion config file and now this is what I can see:

Agent admitted failure to sign using the key.
Agent admitted failure to sign using the key.
Agent admitted failure to sign using the key.
Permission denied (publickey).
svn: Network connection closed unexpectedly

Answer 1

openssh uses a different key format from putty. You would need to use puttygen to convert/export your putty key into a format that openssh can use.

1. Open PuttyGen
2. Click Load
3. Load your private key
4. Go to Conversions->Export OpenSSH and export your private key
5. Copy your private key to ~/.ssh/id_dsa (or id_rsa).

6. Create the RFC 4716 version of the public key using ssh-keygen

   ssh-keygen -e -f ~/.ssh/id_dsa > ~/.ssh/id_dsa_com.pub

7. Convert the RFC 4716 version of the public key to the OpenSSH format:

   ssh-keygen -i -f ~/.ssh/id_dsa_com.pub > ~/.ssh/id_dsa.pub

8. Fix the permissions of the private keyfile:

   chmod 600 ~/.ssh/id_dsa
