uutry time not reached

The venerable uucp program isn't used much anymore because with the ubiquitous Internet, modem to modem communication isn't needed much anymore. However, uucp runs over tcp/ip also and can be convenient and useful in certain situations, so it isn't entirely dead: uucp and xc is an example of where it might still be useful.

You don't have to worry about network failures: uucp will make sure the job gets done as soon as connectivity is back. You don't have to worry about logging either. You can stagger large distributions by specifying acceptable usage times for different machines. Most of the nitty gritty details are already taken care of: you just issue the uucp command and forget about it.

Normally, uucp would be configured to spool file transfer requests and attempt the transfer during certain time periods (when phone rates were low or during periods where machine load was less). You could also manually force a dial attempt with "uutry machinename" but if insufficient time had elapsed between attempts, you'd get something like "retry time (2400) not reached" (the 2400 is configurable). You could over-ride that with "uutry -r machinename".

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
