[Nottingham] flexLM and clock error

[Moses O'Hara]

Hi Dave, 

I guess it'd depend on how the software monitors the clock / date. If it's a simple case that it rights the information to a file some where and uses that to crossreferance your license then changing the file should work ( i suspect if this is the case the s/w people have already tried this with there fixes). If the s/w people can't resolve it then it's probably going to be just as quick to backup changes and restore from a back up. 

More and more s/w manafactureers are using uniquely identifiable traites of the computer to aid with licence enforcement. Techniques such as recording repeating discrepancies of the crystal osc. and building it into the installation so it can't be re disributed. If this is the case and the surge / pigeon soldering has changed one of the said characterisitcs of your hardware then it sounds like reinstall time (be it s/w or os). 

If this doesn't appease pehaps a 'little' bit of strace work might be called for to identify what flexLM is referancing. Iif you've not done this before it can be quite time consuming and tideous ( | less on standby :-) ) 

Have the s/w people offered any other avenue to a fix? Is it a reseller or the manafacturers themselves?

Might be worth while loggin a call with the UoN Staff IT Helpline fi ti hasn't already been done. 

Moses.

We have a piece of comericial software with a flexLM licence, running on a RH9 machine. A while ago we had a couple of power related problems (one surge that blew the motherboard, and then the boss blew the power with some dodgy soldering!), which caused the clock to reset (sometime in 1929?). Once this was set again most things ran fine, but the licence file had identified that the clock had been 'diddled with' (I believe that is the technical term), and this software will now not run. 

The software people have sent though a couple of programs to try and fix this, but nothing seems to have worked. They're still trying, but I wondered if the list might have any suggestions...

Cheers,

Dave
