can ping without firewall; no port 631
Well, since I wrote the below, I've learned a little more about Samba, and got them to at least acknowledge each other. Still can't use Gaurd dog. Still cant print from one to the other.
I'm learning I'm learning
I recently installed mepis 7 on both my laptop and laptop. (I came from Mepis 6.5). since the change I can't get these computers to recognize each others existence, except to be able to ping from one to the other if the firewall (Gaurdog) is off. And I can't discover that port 631 (I believe that is the port for the print server) is open. I don't really know how to find out, or how to open it if it is closed.
Laptop is Amd-64 with a 32bit distro. Desktop is Compaq Presario AMD64 with 32bit distro.
I'm still quite a nuB, so if I haven't given enuf info here, please tell me what you need to know and (hopefully) how I can find out.
. Thanks, Sonshyne5

cups-lpd
cups-lpd(8) Apple Inc. cups-lpd(8) NAME
cups-lpd - receive print jobs and report printer status to lpd clients SYNOPSIS
cups-lpd [ -h hostname[:port] ] [ -n ] [ -o option=value ] DESCRIPTION
cups-lpd is the CUPS Line Printer Daemon ("LPD") mini-server that supports legacy client systems that use the LPD protocol. cups-lpd does not act as a standalone network daemon but instead operates as a socket-activatable systemd(1) service. OPTIONS
-h hostname[:port] Sets the CUPS server (and port) to use. -n Disables reverse address lookups; normally cups-lpd will try to discover the hostname of the client via a reverse DNS lookup. -o name=value Inserts options for all print queues. Most often this is used to disable the "l" filter so that remote print jobs are filtered as needed for printing; the examples in the previous section set the "document-format" option to "application/octet-stream" which forces autodetection of the print file format. PERFORMANCE
cups-lpd performs well with small numbers of clients and printers. However, since a new process is created for each connection and since each process must query the printing system before each job submission, it does not scale to larger configurations. We highly recommend that large configurations use the native IPP support provided by CUPS instead. SECURITY
cups-lpd currently does not perform any access control based on the settings in cupsd.conf(5) or in the hosts.allow(5) or hosts.deny(5) files used by TCP wrappers. Therefore, running cups-lpd on your server will allow any computer on your network (and perhaps the entire Internet) to print to your server. You should use configure the firewall to limit TCP port 515 access to only those computers that should be able to print through your server. cups-lpd is not enabled by the standard CUPS distribution. Please consult with your operating system vendor to determine whether it is enabled on your system. COMPATIBILITY
cups-lpd does not enforce the restricted source port number specified in RFC 1179, as using restricted ports does not prevent users from submitting print jobs. While this behavior is different than standard Berkeley LPD implementations, it should not affect normal client operations. The output of the status requests follows RFC 2569, Mapping between LPD and IPP Protocols. Since many LPD implementations stray from this definition, remote status reporting to LPD clients may be unreliable. SEE ALSO
