Linux for zVM
by Shahin.Suleiman 02 Jul '07

02 Jul '07

Hello folks, I hope I am not on the wrong list. I am looking to install Linux under zVM 5.1 and I can barely spell LinUX. How should I go about it and what Linux distributions can be used under zVM? Thanks. Suleiman Shahin Systems Programmer Palm Coast Data (386) 447 2552

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

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.

Is BIND In CentOS 5.0 Broken?
by Eduardo Dela Rosa 02 Jul '07

02 Jul '07

Hi, I've just isntalled CentOS 5.0 in my machine; selected DNS server during the selection process. After the completing the installation, I wanted to configure my DNS server but it seemed that /etc/named.conf and other stuffs in /var/named/chroot/var/named directory are not there (i.e., *.zone, *.local, etc). Can anyone give me idea? This is the first time that I've tried CentOS; used to have Fedora Core and RHEL; but I know CentOS is a RHEL fork; just don't know what exactly the other differences are. Cheers! -- Eduardo Dela Rosa

installing progs from source on CentOS
by Rogelio Bastardo 01 Jul '07

01 Jul '07

I'd like to install NagiosQL on CentOS, but I don't see a yum package for it, so I'm going to download the source code. If I download it, where in CentOS's file system (i.e. in which directory) is the best place to untar, compile, and run it? (Sorry, I've been spoiled by packages!)
