Hi -
I've just done a "complete" install of Taroon on a scratch box, with
iptables firewalling disabled. The following services are listening on
external network interfaces:
Port State Service
22/tcp open ssh
68/udp open dhcpclient
111/tcp open sunrpc
111/udp open sunrpc
123/udp open ntp
1010/udp open unknown
6000/tcp open X11
ssh (we don't want to lock users out after an upgrade), ntp and dhcpclient
(both manually configured during install) are reasonably justified, IMHO,
but what is the justification for having rpc.statd, portmap and X11
listening by *default* (especially on a machine that hasn't been configured
to use NIS)?
rpc.statd and portmap aren't the exclusive domain of NIS. Both are
enabled by default and used by NFS as client or server. I think they
could be disabled by default instead of being enabled by default.
You can disable both services:
# chkconfig --level 12345 portmap off
# chkconfig --level 12345 nfslock off
If you don't want the NFS server:
# chkconfig --level 12345 nfs off
