Hello Friend's

[root@server .ssh]# ls
id_dsa id_dsa.pub

I don't think it comes by default (but I may be wrong or it may differ on OSes), you could check the id_rsa.pub file, at the very end it might have a comment which can indicate who created the file.

those filee use/still use for connection by pubkey ,
if you coneected to server, that only auth' by key,
you should save it,

Yes it's only used to connect to other boxes; so your server isn't in danger because of it. But I can imagine that if the server is compromised, these keys could be used to ssh into other boxes, making the server a proxy.

However it's not very likely. Still I would check the files, also the file creation date and see if you can think of why they're created.
