[CentOS] Firewalld zone conflict
Hi, In CentOS7 I have added two zones using firewall-cmd, each for different ports/services and interfaces when I try to --add-source to the second zone with an IP that is already in the first I am getting an 'Error: ZONE_CONFLICT' message. Am I trying to do something illogical or is this a feature? Cheers, Colin. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] SELinux prevents my PHP script from sending mail
On Wednesday 02 May 2012, Alan M. Evans wrote: Hello all... I maintain an amateurish email list for my wife's website on my CentOS 6 server. Once-a-month, she sends mail to mylista...@mydomain.com and the /etc/aliases file redirects that to my script: mylistaddr: | /usr/bin/php-cgi /var/www/html/mydomain/email-cgi.php The script, in turn, reads the recipient addresses out of a DB and composes and sends the mails. This all worked great until this month's mailing. Now sendmail just bounces the mail back 554 5.3.0 unknown mailer error 255. When I see programs complaining about unknown conditions, I usually suspect SELinux first, and sure enough... setenforce 0 then everything works like a charm. I wonder what changed between last month and this month? Anyway, I checked the audit.log file and found the relevant AVC denials. I created a local policy (audit2allow) to circumvent the denials, which helpfully prevented the denial messages in audit.log. But the maillist script still fails identically as long as SELinux is enforcing. And now nothing shows up in audit.log. So SELinux is preventing sendmail from calling my maillist script and not reporting the reason. How do I go about figuring out what's broken and how to fix it? Do you have the httpd_can_sendmail boolean on? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] centos rpm package description list?

As I know, we have reference sites like rpm.pbone.net and dag.wieers.com etc that we can search for an rpm package by its name. But what we have if we want to find a rpm package by its description rather than its name? Say we want to find how many solutions do we have for Image processing or Speech processing on centos, so if we know the solution is GIMP so we can search for its rpm package on the mentioned sites but what we can do if we just know the rpm package description?

It shows usable disk space of approx 940 GB but the OS does not see it instead it shows all the 4 * 500 GB HDD. Try discarding the array and rebuilding, perhaps using a different RAID level, see if that makes any difference. I have vaguely similar machines and have not encountered this type of problem, and I'm pretty sure all this range are certified for RHEL. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] [OT] Label Printer Recommendations
Greetings Folks, I am after any recommendations or experiences using Label printers to print barcodes with CentOS, we currently using Star TSP700's but they're not clear enough for the scanners we have. There seems to be plenty of choice but not much Linux support going on, 'Never had anyone ask for Linux drivers before..' seems to be the most common answer when trying to buy. I have also tried a Brother P-Touch QL-550 but can't seem to get that to print at all using the Foomatic drivers available online.

[CentOS] Canon Printer Woe

I have it working on XP and OS X both via USB and network but am having no success with either on CentOS 5.4 . Print jobs seem to be processed correctly by CUPS but the printer doesn't respond at all and the jobs show up as completed in the CUPS job list. I do not know how to test the ccpd daemon but it seems to be running. Any pointers greatly appreciated.
