Restricting mirrors off a repo
by Mauricio Tavares 21 Jan '17

21 Jan '17

What is the best way to specify which mirrors off a repository you want to use? Have a host with rather restricted egress rules and want to allow it to reach a couple of mirrors for each repo it needs. And, yes, I am not ready to mirror them locally.

by Zulqarnain Khan 21 Jan '17

21 Jan '17

Hi, hopping everyone is fine. I am using a Centos 7 server based on Nginx. I am using the server for providing downloadable data. Around 8 TB per day is downloaded. The server was working fine and perfectly. I hired a freelancer to limit the download speed as i am unexperienced with linux (Worst Mistake Ever) he messed up the server and after 4 hours said he cant impletement a simple limit_rate in Nginx. So i said to him revert back the changes and he said its done. Since then i am getting this error abrt-cli list --since 1484935231 Error typed in terminal http://prntscr.com/dy6c4a Here is the Nginx log file http://prntscr.com/dy6k54 Here is my Php-fpm log file http://prntscr.com/dy6koa There servers is taking too much time to respond. Even a simple yum is taking time to respond. Listing directories is also taking time. So please help me out.

Standard Dracut configuration file /etc/dracut.conf
by SUDHANSHU BHUTANI 21 Jan '17

21 Jan '17

Hi Centos Experts, I want to have hands on /etc/dracut.conf file which standard centos 7.3 is using to create initrd.img present in the DVD ISO : /isolinux/initrd.img >From where can i get /etc/dracut.conf, so that i can create exact replica of initrd.img which centos 7.3 is sending in DVD ISO. ? Can any one please send me standard centos 7.3 dracut configuration? My goal is to change some kernel configuration in standard centos 7.3 kernel. I will be adding some new drivers statically and will be building new vmlinuz. I will also be building initrd.img compatible with this new kernel image. Then, i will copy these 2 newly formed images to /isolinux/ in my dvd-iso-layout folder and try to make a new ISO. This ISO should boot well. I need to prepare one complete ISO, which has my new modified kernel and modified initrd Currently, i am facing lot of errors in dracut. Not sure, what am i missing in my initrd.img. Sometimes, it says "/dev/root" does not exist. What command shall i use in centos 7.3 to make a new initrd.img which i can transfer to my ISO for new installation? Regards Sudhanshu

amanda and selinux
by Jon LaBadie 21 Jan '17

21 Jan '17

Anyone familiar with the selinux policy for the amanda backup software package? I'm getting lots of data not being backed up. For example, under /home there are 2 directory trees owned by root. Those get backed up, user home dirs do not. No AVC denials nor messages in /var/log/messages or journalctl log. But if I turn off selinux enforcing, or set amanda_t type to permissive, complete backups are made. I expected the selinux policy would have allowed amanda to be able to read all files. Else, how does one make backups? I'm seeing this on CentOS 7.2, Fedora 24 & 25. Amanda packages from the respective distro repos. As far as I can tell, the selinux policies are the same in all three. But then, I know little selinux speak. Jon -- Jon H. LaBadie jon(a)jgcomp.com 11226 South Shore Rd. (703) 787-0688 (H) Reston, VA 20190 (703) 935-6720 (C)

Can/should I mix entropy sources?
by Steve Snyder 20 Jan '17

20 Jan '17

I've got 2 sources of entropy in my CentOS7 system, a hardware RNG and the Intel rdrand instruction. Is it advisable to just use a single source or can/should I mix the 2 sources? If I mix the 2 sources how is it done? Presumably I could use the rngd service to handle the Intel source, but would it be a problem if 2 entities were writing to the entropy pool? Thanks.

SSSD cache case-sensitivity
by Robbert Eggermont 20 Jan '17

20 Jan '17

Dear all, I'm running CentOS 7.3 with SSSD. I'm using sssd-ad to talk to an AD backend. Group names in the AD contain capitals. When sssd-ad is working normally, group names returned are all lowercase. However, when the AD backend goes offline, group names returned from the SSSD cache contain capitals. The change in case breaks stuff (sshd's AllowGroups, for one). Has anybody else seen this behavior? Is there a way to make the group names uniform, whether they come from sssd-ad or the cache?

CentOS 7 httpd cgi script file not able to write to /tmp
by Jerry Geis 20 Jan '17

20 Jan '17

Hi all, I have a script running in httpd. The script runs fine. However I want to "echo" some debug information into a file. The file is never created. Is there some security thing that has to be enable/disabled to allow a script in httpd to write to a file? Thanks, Jerry

[OT] VOIP
by TE Dukes 20 Jan '17

20 Jan '17

Hello, I changed ISPs a few weeks ago and now I'm on cable. In doing so, I lost the ability to use the DSL as a FAX line. So, I bought an OOMA. Turns out it uses a number of ports, three of which are reserved, 53 TCP/UDP, 110 TCP and 443 TCP. These ports have already been port forwarded from my cable modem/router to my server. I'm thinking this isn't going to work unless I change some ports on my server, which I'm not willing to do. I spent over 30 minutes with their support people last night. It appears the ports cannot be changed on the OOMA device. Are there any work arounds? TIA
