The host to which I dial up for uucp transfers has a different name for my machine than the actual one. I tried changing things in the sendmail.cf file, but still the host responds (once I'm logged on) "you are unknown to me". Is there any thing else that I have to change? Thanks. Dan.

With release 3.x of Ultrix, uucp uses the first element of your hostname to identify itself to the remote system. Usually only the first 7 or so characters are significant. So, if you system is named "prettything.nowhere.com", the system you are trying to call should have entries in it's uucp files for "prettyt" - though depending of the version of uucp "prettything" or the full name may work... For either "bat" or "bat.wing.tv.com", it would simply be "bat". The sendmail.cf file has nothing to do with this and as far as I know, there is no way to override ultrix's use of hostname for this purpose, so you must get the people on the system that you are calling to update their uucp control file appropriately. Newer versions of uucp contain explicit support for aliases, but Ultrix uucp doesn't (or at least it's neither evident nor documented). -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

You didn't specify the type of uucp that you were running, so..... I will tell you about my experiences using the uucp distributed with AT&T System V rel. 2 and above. This version of uucp is often called HoneyDanBer (HDB) uucp after its authors. We support many client sites using TB+ modems and uucp. We ship files of all types using simple uucp. When our company connected our different machines together using StarLan, the software didn't like the machines having identical names. (All of the client sites use the same name in their Systems file.) When we changed the system names to accommodate StarLan, the client sites all said "you are unknown to me." We were faced with changing all of those systems files remotely. Instead we found the MYNAME modifier in the Permissions file. The permissions file is normally used to specify what machines can do when they call your system. However the MACHINE entries are used to specify permissions when you call another system. One of the options in a MACHINE entry is MYNAME. This allows you to use any name you wish when you call another system. Here is a sample entry. MACHINE=remote \ MYNAME=alias_name Where remote is the name of the machine you are calling, and alias_name is the name the other machine expects. By adding this entry to the Permissions file on all our machines, we continue to call clients from any machine, w/o changing anything on the other end. (how VERY wonderful, since I would have had to make the changes. :-) To verify that you are calling a system using the alias_name, use $ uucheck -v to check your uucp files. You should see something like: When we call systems(s): (remote) [* Stuff deleted *] Myname for the conversation will be alias_name. This knowledge has been gleaned from reading between the lines of the AT&T manuals, and a book titled: "Managing uucp and Usenet" by O'Reilly & Associates. (ISBN: 0-937175-09-9) (A Nutshell Publication) (You can order toll free by calling 1-800-338-NUTS. (NUTS=6887 for you European types. :-) This is a really good book if you do a lot of work with uucp and Usenet. It covers the most popular versions of uucp (Not just HDB). It sure beats digging the info out of the man pages. (That like pulling hen's teeth :-) Hope this helps anybody who has this particular problem.
