Hello

It isn't working for me :)
I run ssh-user-config. It asked me which keys I like to create and if I like to add them to
authorized_keys.
$ /usr/bin/ssh-user-config
*** Query: Shall I create a SSH2 RSA identity file for you? (yes/no) yes
*** Info: Generating /home/meyer/.ssh/id_rsa
*** Query: Do you want to use this identity to login to this machine? (yes/no) yes
*** Info: Adding to /home/meyer/.ssh/authorized_keys
cat: /home/meyer/.ssh/id_rsa.pub: No such file or directory
*** Query: Shall I create a SSH2 DSA identity file for you? (yes/no) yes
*** Info: Generating /home/meyer/.ssh/id_dsa
*** Query: Do you want to use this identity to login to this machine? (yes/no) yes
*** Info: Adding to /home/meyer/.ssh/authorized_keys
cat: /home/meyer/.ssh/id_dsa.pub: No such file or directory
*** Query: Shall I create a SSH2 ECDSA identity file for you? (yes/no) yes
*** Info: Generating /home/meyer/.ssh/id_ecdsa
*** Query: Do you want to use this identity to login to this machine? (yes/no) yes

cat: /home/meyer/.ssh/id_ecdsa.pub: No such file or directory
*** Query: Shall I create a (deprecated) SSH1 RSA identity file for you? (yes/no) no

*** Info: Configuration finished. Have fun!

It create $HOME/.ssh with an empty authorized_keys and no keys:
$ ls -alh $HOME/.ssh
total 4.0K
drwxr-xr-x 1 meyer Kein 0 Nov 23 09:06 .
drwxr-xr-x 1 meyer Kein 0 Nov 23 09:06 ..
-rw-r--r-- 1 meyer Kein 0 Nov 23 09:06 authorized_keys


Thanks for any hint
Matthias
