Postfix and LDAP
by Ranbir 15 Dec '15

15 Dec '15

Hi Everyone, I thought I'd try asking here before joining the postfix mail list since I'm running postfix on a CentOS 7 box. I want to look up accounts via LDAP (an IPA server also on CentOS 7). I created an "ldap_aliases" file and successfully tested it with the postmap command: I can get the email address for an arbitrary user. But, when I add the very same file to main.cf, I don't see anything in the normal or debug logs for postfix that would indicate postfix is even trying to do a ldap lookup. Here are the relevant configs: # Virtual domains virtual_mailbox_base = /var/spool/mail virtual_mailbox_maps = hash:/etc/postfix/virtual_mailbox virtual_mailbox_domains = thesandhufamily.ca virtual_alias_maps = hash:/etc/postfix/virtual, hash:/etc/mailman/virtual-mailman, ldap:/etc/postfix/ldap_aliases NB: I believe I don't need to use ldap for virtual_mailbox_maps and virtual_mailbox_domains, but I could be wrong. All I get is errors like this: Dec 14 09:53:35 mailman01 postfix/lmtp[31011]: A968CC2516D: to=<ranbir(a)thesandhufamily.ca>, relay=10.200.5.24[10.200.5.24]:24, delay=1.1, delays=0.78/0/0.01/0.27, dsn=5.1.1, status=bounced (host 10.200.5.24[10.200.5.24] said: 550 5.1.1 <ranbir(a)thesandhufamily.ca> User doesn't exist: ranbir(a)thesandhufamily.ca (in reply to RCPT TO command)) Am I supposed to enable something else in postfix to make ldap work? What I've read about this seems to indicate I'm doing it correctly. -- Ranbir

Centos 6: qemu-kvm: Install guest win10 on host Centos 6
by Dario Lesca 15 Dec '15

15 Dec '15

I have try to install from iso Windows 10 on a centos 6 + qemu/kvm, but the guest not start and reboot after a while. Form this page: http://www.linux-kvm.org/page/Guest_Support_Status#Guest_Support_Status I understand that I must install at least qemu-kvm-2.3.0, but on the server (up to date) is installed qemu-kvm-0.12.1.2-2.479.el6_7.2 and there are no other updates. I can upgrade the server to Centos 7, but on Centos7 the max newer version of qemu-kvm is 1.5.3-105.el7_2.1 My question is: there is some way to install on Centos 6 up to date Windows 10, or I must upgrade / install Fedora 23 server (qemu-kvm- 2.4.1-3.fc23.x86_64) Many thanks for reply -- Dario Lesca (inviato dal mio Linux Fedora 23 Workstation)

CentOS 7, yum-cron
by m.roth＠5-cent.us 15 Dec '15

Hi, folks, Our bastion host decided to update itself in the middle of the night, which gave at least one user issues. So, the question is why? In both /etc/yum/yum-cron-hourly.conf and /etc/yum/yum-cron.conf, apply_updates = no. Has anyone else seen this? mark

Wifi Driver Broadcom BCM4322 not working with Centos 7.2
by melkor.kp 15 Dec '15

15 Dec '15

Hi, I've been using in the past the broadcom wifi card BCM4322 with Centos 7.1 one in the past, with kernel 3.10.0-229.7.2.el7 and driver 6_30_223_248 and it worked well. Now I updated Centos to 7.2 and the driver is not compiling any more under kernel 3.10.0-327.3.1.el7. Neither driver 6_30_223_238 nor 6_30_223_271. Does any body experienced the same issues?

boot order items
by Wes James 15 Dec '15

15 Dec '15

Just side note, when I boot with 7.2 now it has (Core) with Debugging before (Core) now. All the others are the other way around. Also, on my 2011 iMac, the 7.2 kernel won’t boot. I had to go back to the latest I had with 7.1. This has happened in the past, but some time later a newer kernel started working. Thanks, -wes

I don't dispute the value of GUIs. I have a comment and a question, first that in "the data center" my experience is that iptables rules are put into place and only rarely changed thereafter, like the network configuration at the server. But my question was partly this: What is the specific need for a continuously running daemon firewalld if what we wanted was a GUI front-end for iptables? Thanks....Nick Geo
