PPP Over Predictive Support Modem

Pete G — Wed, 24 Apr 2002 12:36:03 GMT

Hello all,

I was wondering if it is at all possible to utilize the predicitve support modem to establish a ppp connection to ftp files from a vendor. The machine is a HP L3000 running HP-UX 11.00. I haven't used ppp in years, and that was on a Linux box to conect to my ISP. Any help on this would be greatly appreciated. Thanks.

Pete

Hi there.
Why opening the system up to everybody, who can dial into the modem ?
btw, the speed is really not satisfying.
Why do these people not use kermit as filetransfer protocol ?
We do this with a software company to transfer new versions.

I have no choice over how we can connect to them. I, personally, would have preferred something like a sftp connection. I need to ppp then once on I will be able to ftp the files from them. To save money, I was hoping that I could use the already configured port and modem being used for Predicitive Support. If that can be done, then I can start trying to get the ppp end going. I have been editing the example files and so far have managed to get pppd running and writing to /var/adm/pppd.log ;) I have no real experience with ppp on HP, as I stated. This is not something I am enjoying but, sadly, is something I have to have in place by the end of May.

Peter,
The support modems won't support ppp. We tried it and eventually we had to have a ASE engineer us a complete ppp solution, he had to use US Robotics modems. I wouldn't spend too much time on predictive however. HP is rolling out ISEE, which is the replacement for predictive.

Hi Peter,

Reflection has an own protocol, embedded into the terminal-emulation software.
I am pretty sure, that other products have similar features.

Volker

This is from the online documentation:

You can transfer files in Reflection using the Transfer command on the File menu. You can transfer any type of file, not merely text files, to and from a host computer. Use Reflection to transfer files between your PC and an HP 3000 (including Classic, MPE/iX, and POSIX), VMS (including Digital VAX and Alpha computers), ULTRIX, or UNIX system. Or, transfer files to any host or electronic service that supports the Zmodem, Xmodem, Kermit, or SuperKermit protocols. Reflection includes its own proprietary protocol, called the "WRQ/Reflection Protocol."

Before you can transfer files using Reflection's proprietary protocols, there are two steps you must perform:

1 Upload the host program.

Host programs are provided for HP 3000, VAX/VMS (DEC), AXP machines, and UNIX operating systems. A system administrator may have already uploaded the host program; if so, you can skip this step.

2 Configure the file transfer settings.

Click Transfer Setup on the File menu to configure the file transfer settings. For most situations, you can configure for file transfers by choosing a preset configuration in the Protocol panel.

really simple, just tried it for interest!
Took 5 Minutes!
You simply run the delivered Reflection Macro like this:

Initializing Global Variables...
Getting Upload Options...
Preparing Reflection for Upload...
Preparing Host for Upload...
Uploading Unxlink2 Source Code to Host...
Uploading "unxlink2.c" to Host...
Trying WRQ Protocol ("RUN VAXLINK2")...
Trying WRQ Protocol ("unxlink2")...
Trying Old-WRQ Protocol ("unixlink")...
Trying Kermit Protocol...
Creating a Mini-Kermit Program. Please Wait...
Starting Kermit Transfer...
Uploading "unxxfer2.c" to Host...
Trying Kermit Protocol...
Compiling WRQ Transfer Host Program. Please Wait...
Testing Unxlink2...
Restoring Host System...
unxlink2 successfully uploaded and compiled on host.
Done.

Relocate the unxlink2 executable to a suitable location and adjust permissions afterwards. Customize filelocation in Reflection client. You'll get a nice dialog to move the files (see attachment)
