problem with shared memory
« on: May 25, 2007, 01:23:29 PM »
Hi,
  I got a problem with shared memory.
Actually our linux system is using by 2 users. We have an application which will generate a shared memory segemnt and is used by all the users. That segment is related to fonts.If the other user is owner for this segment then I am not able to get the fonts on my display. But if I am the user then we both are getting the fonts. Not able to understand why it is so..permissions on that segment is 777 only.
  when I am trying to figure out the difference b/w both the accounts, actually I am logging as an NIS user where as she is having local machine account. but this is not giving problem, b'caz I tried by using another local system account, stiil we have the same issue.
  Please help me to know exactly where the problem is...

  One more doubt is when we create an account in a linux machine, to generate encrypted password will it use diferent algorithms.. means if one is generated using MD5 based algorithm and another one is DES algo.
like.

Hmm..... problem is somewhat different..................
I am not sure but may be its related to group policy

Check following things:

1) Check the groups in which that users belongs ...............
2) Check wheather acl's are enabled or not ?
3) Check wheather SUID bit is set there or not?
 

Ricky , Dragoncity Any comments?
