I cannot access home samba share from windows. Windows client displays a permission denied error. The problem is not Linux permissions for the user directory, permission is still denied when permissions are to 777. I don't think the problem is selinux, because no denials appear in any logs. I don't think it's an extended attributes issue from xfs, because I don't see any attributes

I used setenforce 0, and I was extremely surprised to see a burst of selinux denials appear in the journal. So I corrected the problem with: setsebool -P use_samba_home_dirs 1 And updating some policies. Thanks very much! I have never before dealt with selinux denials that don't appear in the journal until "enforcing" is changed to "permissive". Is this a samba

Dear R-listers, I would like to carry out a very basic descriptive analysis of homicides rates in Italy, taking into account both the spatial dimension (103 provinces) and the temporal dimension (10 years), but no covariates.

:( Exactly as the title says, A majority of online gaming sites and browser based mmo games refuse to load on to a mozilla browser with WINE installed. Examples are www.armorgames.com www.freeonlinegames.com www.bigpoint.com What they do is they load a little bit so I can see the website, But then it freezes up and im forced to quit the session and start over again...with the same results...

All, I am running into a situation in which one of my ext3 filesystems is getting hung during normal usage. There are three ext3 filesystems on a CompactFLASH. One is mounted as / and one as /tmp. In my test, I am copying a 100 MB file from /root to /tmp repeatedly. While doing this test, I eventually see the copying stop, and any attempts to access /tmp fail - if I even do ls /tmp the

Hey all, Long time user of Centos, I really love what you guys are doing here. I have a farm of 50 Centos 4.1 machines. (originally 4.0 updated with yum up to current 4.1).

Funny that they were the only ones that are booted into the new kernel! The rest

I'm upgrading my primary server from RH 7.2 to CentOS-4.3.ServerCD. I REALLY like the ServerCD. Who needs all the fluff that comes with a standard distro? If I want a system-config-gooey I can run Xnest [1] and ssh -X from my laptop. Anyway I have two questions: 1) How can I collectively stop all the NFS, portmap, whatever? I'm hoping it can be manipulated as a group because occationally
