I have a folder in /srv/backups. I have a users group that has access to the backups folder with rwx access.
I have added myself to the users group
but when i try to cd into the backups folder i keep getting a permession denied.
Any ideas on what im doing wrong?
The reason is that your groups don't get updated until you log out and back in.

I am able to login to my SSH account, then while creating a file in the location /var/www/html it give me permission error . It seems that the owner of this folder is root. How can I able to get access to this folder to upload files ?
According to your description, if you want to upload your files to Azure VM, you could upload files to your /home/user's folder, then copy them to /var/www/html.
I have a file(file) with permission 500. In Linux, I tried to copy (using cp) that file into a folder (a) whose permission is 600. Even though folder have write permission, I am getting " cannot stat `a/file': Permission denied error.
Could anyone explain why is it so?
Is it because directory does not have executable permission ?
Execute bit allows the affected user to enter the directory, and access files and directories inside.

I am using RStudio server (Version 0.98.994) on Ubuntu 12.04.
Our group works on a external share drive together and would like to open the same project.
When I open a project file created by other colleagues, I got an error with permission denied (Sorry I cannot show the error message as I already changed the permission manually).
After checking the file permission, I found the default permission is "-rw-r--r-x" for *.Rproj and .Rhistory, "drwxr-sr-x" for ".Rproj.user". So no write permission for group.
In the external share drive (no sure about system, should be Linux), the default permission is rw for group.
How could I change the default permission for *.Rproj, .Rhistory and .Rprojt.user?
Thanks for any advice. Please let me know if my question is not clear.
EDIT:
I created new file and folder in the external share drive from command line. The default permission is -rw-rw-r-- for file and drwxrwsr-x for folder, as I expected. It seems RStudio server created these new files with their own default permission.
Could I change the default permission of these files *.Rproj, .Rhistory and .Rprojt.user when RStudio server creates them? i.e. Add write permission to group.
The default permissions for Directories are 777 which is read/write/execute and for Files it is 666 which is read/write. But then every system has a umask value, which is normally 022.
So when you create a directory it will have permissions 777 but it will take away the umask value of 022 and leave you with your default permissions of 755 which is rwxr-xr-x
You can change the value of umask by simply entering the command
umask=055
This will set the umask value to 055 and whenever you create a new file/directory, 055 will be taken away from the permissions.
Again look at a newly created directory with permissions of 777 and the umask value is taken away so the directories permission is 722 which is rwx-w--w-
Again look at a new directory with permissions
I am using Jenkins to build my project in a Linux machine. During build operation files are read from a source location and files are to be copied to a new destination location.The source and destination locations are input by the user from Jenkins UI. I want the user to be able to select any folder located within his/her home folder as source or destination. For example: /home/jdoe/folder.
Currently, any folder inside /var/lib/jenkins, with jenkins:nogroup user-group, can be selected. However, a folder inside /home/jdoe/folder with same (jenkins:nogroup) user-group, and with the same permissions as the folders within /var/lib/jenkins, cannot be selected. I get a permission denied error on trying to read or write inside /home/jdoe/folder.
What can I do to enable reading and writing to a folder within the home folder of the currently logged in user? Can I set up Jenkins in a certain way to be able to do that, or do I have to change group settings for the home folder?Could you suggest a good configuration for me to be able to make this work?
Would there be any difference in using Jenkins on an Windows platform?
First make sure that the folder is having read-write access for jenkins user group.
sudo chmod -R 77 /home/jdoe
Also as in comment by Daniel, grant execute permission on the /home/jdoe folder.
sudo chmod a+x /home/jdoe
I have a cloud hosting linux solution. I had vsftpd working on it, but after having issues and tinkering with a lot of settings, I now have an issue where users can login using FTP and connect to the correct home directory, navigate within it, download files but they cannot upload files to the server. They get a time out error, which appears to be a permissions error, but I can't narrow it down any more than that. /var/logs/syslog gives nothing away.
The folders belong to the users. The parent www folder is set to 555. Can anyone help with this issue at all?
Cheers,

Try to set the permissions to 755, 555 doesn't allow writing for anyone. Are your user and group different?
You also may need to enable logging for FTP server. The time out error may include some other errors, not only permission denied.
To have extended logging change the variables in your ftp config file:
dual_log_enable=YES
log_ftp_protocol=YES
xferlog_enable=YES
syslog_enable=NO
and check the log file name there.
you must create a folder into user folder (Example : /var/www/user1/upload).
and set permission 777 (Example : chmod 777 /var/www/user1/upload).
then upload file into this folder.
