That would be a symlink to the executable for that process. Normal ps lives in /bin so the link should point at /bin/ps. If it is connecting out to a remote host, it's likely not the normal ps, just something that's masking itself to make it less likely to get picked up. -- David Hollis <dhollis@xxxxxxxxxxxxxx> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
