My company has 300 shop-based laptops that dial-up head-office servers via PSTN daily to transfer their sales data and to collect a group of other files at the same time. The files normally exchanged are quite small - about 10K - but ocassionally we have to sent 1-2Mb files up to the laptops. They are transferred at any time of day or night and the dial-up lines are frequently problematic so we often get breaks, failures and re-tries. The servers are running NT4.
We have been using Kermit under Windows 95 up to now to make the dial-up connection, negotiate the connection an therafter manage it. The problem is that we are moving to a VPN later this year and will need to use Dial-Up Networking to make the connection. We have experimented and find that Kermit is flakey over DUN. It is still a single-user system and we are having to create multiple windows on the server. The negotiation between Kwermit and DUN is not very reliable and sessions can hang under some circumstances.
We would like to move away from Kermit and use FTP. However, there is nothing in FTP to manage the connection. I wonder if there is a wrap-around aplication we can use to manage the session, retries, logging, timing out etc. I'd rather use a proprietry product if one exists as I want something that is very robust.
