Generating DSA keys of different length

[Greg Lambert]

What do you mean by "defined"?  ssh-keygen lets me specifiy values different that 1024 without complaining.  In fact it created keys of different length.  although I am having trouble verifying that the key length is equal the number of bits I specified:
 
/home/greg/.ssh$ ssh-keygen -b 512 -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/greg/.ssh/id_dsa): 
/home/greg/.ssh/id_dsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/greg/.ssh/id_dsa.
Your public key has been saved in /home/greg/.ssh/id_dsa.pub.
The key fingerprint is:
34:f8:02:39:2a:f8:67:3f:8a:e9:40:b5:a8:20:75:58 WELLIE at OMVSH

/home/greg/.ssh$ ssh-keygen -l -f /home/greg/.ssh/id_dsa
512 34:f8:02:39:2a:f8:67:3f:8a:e9:40:b5:a8:20:75:58 /home/greg/.ssh/id_dsa.pub
/home/greg/.ssh$

dsa is only defined for 1024
