I am trying to chown certain directories and binaries for the Apache user. How can I (a) find out the user Apache is using, and (b) the current owner on a given (or group of) folder(s) / file(s)? Thanks

SSL accelerators anyone?
by Florin Andrei 02 Jul '07

02 Jul '07

Anybody using hardware SSL accelerators on CentOS? The architecture that I'm looking at is CentOS 4 32 bit and Tomcat, and the motherboards can accept PCI Express cards. But I'm interested in any observations at all, even on different software and hardware versions - what works for you, what to stay away from, etc. -- Florin Andrei http://florin.myip.org/

Centos 5 32-bit vs 64-bit question
by Scott Ehrlich 02 Jul '07

02 Jul '07

I'm trying to install a custom greeter into a newly installed 64-bit Centos 5 system. I originally tried to modify Xsession to include xpop /path/to/text_to_dispay as the first executable line, but that didn't work. Then I read about gdmconfig which led to gdmsetup which led to custom.conf. Nothing, so far, is producing a custom banner prior to login. Is this an issue with CentOS 5, an issue with the 64-bit version, or something else I need to learn? Thanks. Scott

CentOS version of /srv/www/htdocs ?
by Rogelio Bastardo 02 Jul '07

02 Jul '07

I'm installing NagiosQL on CentOS 4.5 and am trying to follow these instructions http://www.nagiosql.org/wiki/Documentation "....decompress the nagiosql-*.tar.gz to a directory accessible by your webserver (e.g. /srv/www/htdocs)" But since there is now /srv/www/htdocs folder on my installation, I'm not sure what to do on CentOS instead. Any advice?

dumb sendmail question -- how to get outbound messages to use "example.com" instead of hostname?
by Jeff Potter 02 Jul '07

02 Jul '07

Hi List, I have a dumb sendmail question, and I'm wondering if anyone can point me in the right direction (besides "sendmail list is two doors down on the left" ;-). One of our clients has a bunch of servers -- CentOS 5 -- that are on only a private network that's NATted to the outside world -- that is, those servers can initiate outbound connections fine, but don't have valid IPs / hostnames as far as the outside world is concerned. The problem is the hostnames of these machines don't exist in real DNS anywhere, so when they try to send mail to the outside world, other mail servers are seeing an invalid domain in the from address and summarily rejecting the messages (which makes sense). I need to figure out how to tell sendmail, when sending outbound messages, to use the domain name "example.com", instead of "subdomain.example.com". It would seem simple in /etc/mail/sendmail.mc: MASQUERADE_AS(`example.com')dnl LOCAL_DOMAIN(`example.com')dnl FEATURE(`masquerade_envelope')dnl FEATURE(masquerade_entire_domain)dnl MASQUERADE_DOMAIN(betsy.example.com)dnl (Followed by a make -C /etc/mail; service sendmail restart) This doesn't seem to work. The odd thing is that, when I send a message out to an external address of mine, the bounce back to root *does* get through successfully -- the from address at that point is "MAILER-DAEMON(a)example.com" so it allows it. Thoughts? I'm thinking I'm missing something realllllllly basic. best, Jeff

custom SELinux?
by Florin Andrei 02 Jul '07

02 Jul '07

I need to upgrade a server running an old Fedora version. The new OS will be CentOS 5 64bit. I want to put /var/lib/cyrus and /var/spool/cyrus (all the variable files for the Cyrus IMAP server) on the same partition like /home - this way, all the "user-related stuff", home pages and email, stays on one partition. The problem is SELinux. On Fedora, I had to customize the SELinux attributes so that SELinux would grant the Cyrus processes access to the Cyrus stuff in /home But, after doing a relabel of the whole disk, the custom attributes were wiped out. I want to avoid that on CentOS 5. So, I need to tell SELinux "hey, this stuff under /home/foobar/spool/cyrus is just like /var/spool/cyrus, don't relabel it to something else". How do I achieve that? -- Florin Andrei http://florin.myip.org/

good resources for making RPMs
by Rogelio Bastardo 02 Jul '07

02 Jul '07

Could anyone recommend some good resources I might go to for making an RPM? (Ultimately, I'd like to make a dpkg. I hear alien is a good way to do that, but am open to any other ways of doing so.)

Re: [CentOS] dumb sendmail question -- how to get outbound messages to use "example.com" instead of hostname?
by Brent L. Bates 02 Jul '07

On our servers here are some sendmail.mc lines referring to our domain. May be they will help. These are from our main server: define(`confDOMAIN_NAME',vigyan.com)dnl CLIENT_OPTIONS(`Family=inet,Addr=vigyan.com')dnl define(`SMART_HOST',`vigyan.com')dnl FEATURE(`smart_host_domain',`vigyan.com ')dnl These are from our slave servers: CLIENT_OPTIONS(`Family=inet,Addr=slave.vigyan.com')dnl MASQUERADE_AS(vigyan.com)dnl MASQUERADE_DOMAIN(vigyan.com)dnl FEATURE(`allmasquerade')dnl FEATURE(`masquerade_entire_domain')dnl FEATURE(`masquerade_envelope')dnl define(`SMART_HOST',`slave.vigyan.com')dnl FEATURE(`smart_host_domain',`vigyan.com ')dnl Good luck.

by Jordi Espasa Clofent 02 Jul '07

02 Jul '07

Hi all, I'm planning to use Bacula in production environment. I've seen the Bacula packages are not provided neither by any official repo nor any third popular repo (as rpmforge). ¿Anyone use bacula in CentOS 5? -- Thanks, Jordi Espasa Clofent
