Am I hacked??

Hi. Still running Suse 8.2. When I log in as a user, gkrellm shows 2 users logged in. In shell, the "user" command shows "currentuser currentuser currentuser", three times. Thats it. My 9.1 install on a different box shows only one user after the "user" command. Am I hacked? -- Jim Flanagan linuxjim@jjfiii.com
