Perderabo;

Thanks for the input. I haven't thought about the dcd/dsr thing, but I have used the PC in question as a serial terminal when hooked up to another PC running agetty quite recently. Doesn't that mean that dcd/dsr shouldn't be an issue in this case?

I noticed another thing just now, the UNIX machine has several "CS" lights. Is this some type of "Clear to Send" indicator? You see, the "CS" light above the DB9 port (male) where I've plugged my null modem cable in isn't lit, which worries me a bit. Instead, the "CS" light goes on first on the Ethernet card (a BNC connector type, so I have no way of hooking anything up that way) and then on something that looks like a 50-pin SCSI port (female). After maybe 30 seconds, the light changes to the Ethernet card again and then it keeps changing between the two repeatedly until I turn it off.

I'm new to the concept of hardware terminals, but is it possible that the VT100 terminal was in fact plugged in on the SCSI-port?

EDIT; I took a closer look at the Ethernet card again. There's a 15-pin female port underneath the BNC port. Could perhaps that be where the terminal was plugged in?

oidentd_masq.conf

oidentd_masq.conf(5)						File Formats Manual					      oidentd_masq.conf(5)

NAME

       oidentd_masq.conf - oidentd IP masquerading/NAT configuration file.

DESCRIPTION

       If you are using IP masquerading or NAT, oidentd can optionally return a username for connections from other machines.  Support for this is
       specified by calling oidentd with the -m (or --masq) flag and by creating an /etc/oidentd_masq.conf file.

       oidentd can also forward requests for an IP masqueraded connection to the machine from which connection originates by way of the -f option.
       This  will  only  work if the host to which the connection is forwarded is running oidentd with the -P (proxy) flag, or if the host's ident
       daemon will return a valid reply regardless of the input supplied by and the address of the host requesting the info  (some  ident  daemons
       for windows do this, maybe others).

FORMAT

       <IP Address|Hostname>[/<Mask>] <Ident Response> <System Type>

       The  first  field  contains the IP address or the hostname of a machine that IP masquerades through the machine on which oidentd runs.  The
       mask parameter can be either a network mask or a mask in CIDR notation.	A mask of 24 is equivalent to  255.255.255.0,  a  mask	of  16	is
       equivalent to 255.255.0.0, etc.

       The second field specifies the reply that oidentd will return for lookups to the host matching the IP address specified in the first param-
       eter.

       The third field specifies the operating system the machine matching the first parameter is running.

EXAMPLES

       <Host>[/<Mask>]		<Ident Response>    <System Type>
       192.168.1.1		     someone		 UNIX
       192.168.1.2		     noone		 WINDOWS
       192.168.1.1/32		     user1		 UNIX
       192.168.1.0/24		     user3		 UNIX
       192.168.0.0/16		     user4		 UNIX
       somehost 		     user5		 UNIX
       192.168.1.0/255.255.255.0     user6		 UNIX
