vsftp - some users see files, some don't, but all users are in same group

anon091 · 01-18-2010, 11:22 AM

When I have different people log into our ftp and browse to the same folder, some people see the files inside, some don't. all the user accounts are in the same group, which has permission to this folder. but the one user who can see the files is the owner.

how can i fix it so everyone in that group who's the owner of the folder can see the files?

Did you mean, only root was able to see the files, others did n't
is n't it ?

use chmod

#chmod 755 -R <folder name>

no, i meant the owner user of the folder could see them, but members of the group couldn't. but now, without me changing anything, group members can see the files now .. WEIRD

may be "umask" has changed.

checkout default umask =022 => no other can see the files except owner.
if it is changed every user can see.

change umask value to default . i.e. 022

where do i find that at? nobody would have been changing settings on the server.

a person can change his umask value. may be some users modified their umask value's.

how do i check it?

open your terminal

Code:

#umask

if you recive 022 , then permissions are RWXR-XR-X

you can modify by simple teminal command.

Code:

#umask 077

now create a file and check. only owner can see the files. others are restricted.

none of the people who couldn't see the file temporarily have CLI access, so that can't be it. must just have been the server or ftp clients not behaving well together.

You might want to

chmod g+s dir_in_question

which will ensure all files (subsequently) created in that dir are group owned by the dir's group.
