Hi, I was wondering if any real-world type people out there have managed to nab HDB uucp. System V uucp is woking to a point, but I'm finding the six character limitation on machine names to be a problem. Serval of the machines I want to exchange mail with are non-unique in the first six characters. The result is that mail winds up not getting delivered properly. I also have problems with the host that I talk to, neoucom, not recognizing my machine, impulse, when I poll them for my mail. Neoucom says, oh impuls is calling in, that ain't in my systems file, I'm not gunna forward any mail there. I don't really want to rename my system. I asked a person who has a license to the Sys V, version 2 source to look at the files used to build uucp. He told me that removing the system naming restrictions would be more difficult than changing a few #defines. Apparently, the restrictions are pretty much embeded. I haven't seen the code (for obvious reasons!), so I take him at his word that it isnt't worth thinking about modifications of the 3b1's uucp. Does anybody know what the rationale for chopping off system names (including your own system's) to six characters in uucp is? Or, am I just being stupid and missing something? --Bill

There's a variable in the form files called Flen (I think) that you can modify to allow an entry of more than 6 characters. I'm not sure what the names of the form files are (I'm an "unreal" AT&T type :-) and have HDB), but they reside in /usr/lib/ua; I think they're called Lsys[something- or-other].form. If you don't want to edit those form files, you can set your node name by logging in as root and executing setuname -s systemname -n systemname. No six-character restriction applies with this. For the names of other systems you communicate with, just edit /usr/lib/uucp/L.sys, and make any changes to the system names listed you need to. This is what I used to do before I got ahold of HDB. Just as an aside, I also wish it were possible for the multitudes to get HDB. The uucp that comes with the 3B1 is pretty pathetic. Sean

The six-letter system name restriction seems to be hard-coded into
/usr/lib/uucp/uucio itself. I asked the administrator here to
examine his copy of Sys V, relase 2. Apparently, uucico is built
from cico.c, pk0, pk..., and uucp.h found in /usr/src/cmd/uucp.
He told me that there is an #ifdef for SYSNSIZE in uucp.h, but
alas, there are many places in the code that have the decimal
constant 6 "hardwired in" dealing with the system name size. Since
I do not have a license **I have not looked at this code** (which
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
is for the vax release anyway).
If the uucp on the 3b1 is built from the same source code and
SYSNSIZE was not undef'ed at compile time, AND the code was not
fixed-up to change the constants to #ifdefs, then there isn't much
hope for the 3b1.
Uisng setuname doesn't seem to help, uucico always still logs into
the other machine with Shere=impuls.
Happy holidays,

The form file for setting the mail name of your system is /usr/lib/ua/Namesys.form. Flen is set to 6, so you'd have only to change that to a larger number to get a longer node name. As far as "Mail Names of Other Systems" is concerned, the only easy fix (that I'm aware of, anyway) is to edit /usr/lib/uucp/L.sys. UA calls /usr/bin/mailsetup to set up connections to other systems. That program is "mc68k executable" and doesn't use form files. Sorry 'bout the incorrect info. Sean

That doesn't seem to matter to uucp which blithely still pipes up with Shere=impuls (instead of impulse) when uucp from another system logs in. It is true that the mail headers gnerated (by mailx) have the full name, impulse, in them so UNAME is getting set correctly.
