...e methods used don't work for me. I won't pretend I understand linux or samba permissions because every time I think I've got it, I turn out to be wrong. So here goes. Let's say I have 3 users & 2 groups. each group has it's own directory. user1 is a member of grpA & grpB (needs rwx access to grpA & grpB directory & all files). user2 is a member of grpA (needs rwx access to only grpA directory & all files. user3 is a member of grpB(needs rwx access to only grpB directory & all files. When a user creates a file I want the file to have -rwxrwx--- (...

Hi, When I try to do anything on my samba system a connection is made to IPC$, but this is mapped to a directory /root/tmp. This seems odd. To make matters worse ordinary users cannot access this directory, so the only user who can access the IPC$ share (ie, do anything at all) is the root user. What have I don wrong. I cannot find any reference to IPC$ being linked to a directory

I have not really used lm before and I was hoping for some help on a simple problem. Here is a toy version of the problem I want to solve. y x grp -.9 1 a -.8 2 a -.7 3 a -.7 1.5 b -.5 2.5 b -.3 3.5 b -.19 2.7 c -.11 3.7 c -.41 4.7 c I want to fit a model that has one y-intercept and three slopes, one for

Does samba returns the universal groups for the user using wbinfo or some other command? Does samba rettun the domain local group assigned to user for trusted domain? Suppose we have a forest with two domains A and B. Doamin B has a domain local group of 'grpB'. Domain A has a user called 'user1' and it is a member of "DomainB/grpB". Does samba return the above group when queried for the groups of "user1"? Thanks for your help.

I'd like to do a simple one-way ANOVA comparing the means of 6 groups. But it seems like the only way to do an ANOVA in R is to specify some sort of model, where there is an outcome or dependent variable that is a function of independent variables (linear model). But I don't have a linear model, I just want to do a simple ANOVA (and f-test) to compare the means. How do I do
