Digital Equipment DecServers do this over LAT - a proprietary protocol similar to rlogin/telnet ... If you have any Vaxes running VMS at your site you can use one of their servers but you have to originate the login to the console from another DecServer. It works pretty well but the limitation, of course is that you need VMS to load the Decservers. ---- Jay W.

We have an unusual situation that I'd like to user a terminal server for. I'm interested in opinions on which terminals servers might be able to accomplish what I want to do. We have quite a few machines in our lab. Using a lab machine requires connection to the consoles (there are two) via RS-232. However, you can do lots of work without ever being in the physical presence of the machine. Right now we've run serial connections to some async ports on a time sharing machine and you can use tip, kermit, etc. to get your hands on the consoles without having to visit the lab. You can be in your office and use your workstation, which is a much more comfortable and productive environment for many people. Nice as this is for the users, it's a pain for the sys admins. If someone wants to use a particular lab machine via tip, they have to have a user id on the machine that has its console connections. We also get to string lots of serial cable from the lab into the computer room. It's ugly, it's inflexible, there's got to be a better way. What we really want to do is hook up the console ports to a terminal server and have people telnet/rlogin to the terminal server and then come out through the serial ports--exactly the reverse of how you'd normally use a terminal server. I'm told that most terminal servers don't have the ability to accept incoming telnet/rlogin sessions in the quantity necessary to make this viable. Anyone out there have some suggestions?

Just a few nits. One, LAT is only as proprietary as UNIX is. If you pay the license fee you get the spec and code. Second, VMS now supports host initiated LAT connects. This is great for VAX<-->VAX connections but is also useful in the environment described by the origonal poster. Third, LAT is available for a wide range of systems beside VMS. From our company, LAT is available for systems such as IBM R/6000, SGI, Sun, Mips, Alliant, Stardent, Tektronix, Data General, Encore, Modcomp, Arix, Sequent and others. Your last comment about needing VMS is false. There are also a number of terminal server vendors that support a telnet/lat gateway ability such as Datability. >---- >Jay W.

Actually, most terminal servers that I have seen will allow you to do this... I am doing it with cisco terminal servers on a routine basis. I know that others work as well.

Now, if you're willing to buy a non-DEC server, I know of at least one that will use TFTP to download its code from a TCP host if it can't find a DEC machine that supports MOP. Once the download is complete, you have both Telnet and LAT on the server. On the other hand, if you're willing to buy a non-DEC server, you can get a server that supports both TCP and LAT and loads itself from a floppy disk, from Xyplex. Of course, those are a little pricier. DISCLAIMER: neither I nor the Boeing Company are endorsing anything here. -- Jeff Carroll carroll@ssc-vax.boeing.com
