yum-cron email notification doesn't appear
by 1th＠setevoy.kiev.ua 11 Aug '14

11 Aug '14

Hi. I'm installed yum-cron and set: # by default MAILTO is unset, so crond mails the output by itself # example: MAILTO=root MAILTO="root(a)domain.org.ua" I see in log that yum-cron done it's job: # grep "yum" /var/log/cron Aug 11 03:08:02 venti run-parts(/etc/cron.daily)[4516]: starting 0yum.cron Aug 11 03:49:30 venti run-parts(/etc/cron.daily)[4761]: finished 0yum.cron And I see that packages really updated, but - I don't see email notifications in my mail box... I got notification from spamd, for example, but nothing from yum-cron. How can i find it in maillog? Some text from 'Subject'? # grep "yum" /var/log/maillog Doesn't give result. Or - some other way to check? Thanks for tips.

Centos 7 - iptables service failed to start
by Neil Aggarwal 11 Aug '14

11 Aug '14

Hello all: I did a fresh install of CentOS 7 on a new machine. I wrote /usr/local/bin/firewall.stop to remove all the firewall rules. It contains this code: # Flush the rules /usr/sbin/iptables -F # Set the default policies to accept /usr/sbin/iptables -P INPUT ACCEPT /usr/sbin/iptables -P OUTPUT ACCEPT /usr/sbin/iptables -P FORWARD ACCEPT I wrote /usr/local/bin/firewall.start to set the firewall rules. It contains this code: # IP definitions ETH0_IP=a.b.c.d # Load the FTP conntrak module /usr/sbin/modprobe nf_conntrack_ftp # Set the default policies to drop all packets /usr/sbin/iptables -P INPUT DROP /usr/sbin/iptables -P OUTPUT DROP /usr/sbin/iptables -P FORWARD DROP # Flush any existing rules /usr/sbin/iptables -F # Allow loopback traffic /usr/sbin/iptables -A INPUT -i lo -j ACCEPT /usr/sbin/iptables -A OUTPUT -o lo -j ACCEPT # Allow icmp protocol packets /usr/sbin/iptables -A INPUT -i eth0 -d $ETH0_IP -p icmp -j ACCEPT /usr/sbin/iptables -A OUTPUT -o eth0 -s $ETH0_IP -p icmp -j ACCEPT [ Additional allow rules here ] If I run the firewall.start script manually, it sets the iptables rules correctly. If I run the firewall.stop script manually, it removes the iptables rules correctly. The problem comes in when I am trying to execute this from systemd. I wrote /etc/systemd/system/firewall.service with this content: [Unit] Description=Iptables firewall Before=network.target Wants=network.target [Service] Type=oneshot ExecStart=/usr/local/bin/firewall.start ExecStop=/usr/local/bin/firewall.stop RemainAfterExit=yes [Install] WantedBy=multi-user.target Now, when I run systemctl start firewall.service, I get this output: Job for firewall.service failed. See 'systemctl status firewall.service' and 'journalctl -xn' for details. If I do systemctl status firewall.status, it gives me: firewall.status.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) journalctl -xn gives me this output: Aug 10 06:09:38 jamm23.jammconsulting.com systemd[1]: Starting Iptables firewall... -- Subject: Unit firewall.service has begun with start-up -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit firewall.service has begun starting up.

CentOS 6.5 printer weirdness...
by Robert Heller 10 Aug '14

10 Aug '14

Ok, it is consistent and repeatable: *Everytime* I do a routine 'yum update' on the CentOS 6.5 server (64-bit) the printers (both of them networked laser printers, one an [old] HP Laserjet 4200 and one a [new] Brother MFC-9970CDW), cups loses the ability to print (its filter chain becomes broken). According to the CUPS mailing list, this error is 'never' because of of problem with cups, but always with the 'underlying operating system' -- eg the 'underlying operating system' has messed with the filters CUPS uses for the printers. So is this a *known* problem? Or is there something Redhat has done to the distributed cups RPM (or is it something the CentOS developers have done to the Redhat source rpm)? I noticed that the update I just did included an updated cups RPM. The *appearent* cure (workaround?) is to delete the printers, and re-install them. Has anyone else had this problem? -- Robert Heller -- 978-544-6933 Deepwoods Software -- Custom Software Services http://www.deepsoft.com/ -- Linux Administration Services heller(a)deepsoft.com -- Webhosting Services

centos 7 iscsi saveconfig doesn't
by me＠tdiehl.org 08 Aug '14

08 Aug '14

Hi, I am working to get iscsi running using targetcli. So far everything seems to be working except for the fact that when I run saveconfig, exit the targetcli shell and reboot, the iscsi configs are gone. If I run restoreconfig, the configuration gets reloaded and all is well. Can someone tell me how to get the targetcli configuration to persist through a reboot?

Per process memory monitoring tool
by przemolicc＠poczta.fm 08 Aug '14

08 Aug '14

Hi all, I am looking for a tool which let me monitor memory consumption per process on CentOS 5/6. The tool should be able to save its history so I could see what amount of memory was consumed yesterday/week ago/etc by each process. Can you recommend anything like that ? Best regards P.

sssd and authconfig and ldap database lookups
by Mauricio Tavares 08 Aug '14

08 Aug '14

So I am feeling rather frustrated with sssd today: 1. I see that when you install sssd (this is centos 6), sssd.conf is not created. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/ht… implies that if I want to use sssd I need to create the sssd.conf file first. Any reason why? 2. I also noticed if sssd.conf is not there, authconfig won't create it even if you tell it to --enablesssd. How so? I thought that if you are using sssd, it would have stuff like kerberos and ldap (to pick a couple of examples) configured there. 3. It seems if I want to, say, define ldap_user_search_base I must do it directly in sssd.conf instead of passing some kind of argument to authconfig. Am I correct? If so, which files does authconfig affect? I thought it was the *proper* way to configure all the authentication thingies so to make sure they all played together. But, it seems that you have to configure sssd.conf and then use authconfig... or not. Brain hurts

KVM in CentOS 5?
by Marko Vojinovic 08 Aug '14

08 Aug '14

Hi folks, I've been trying to do some KVM virtualization on a C5 host, and to my surprise, there seems to be no kvm package in any of the repos. Yum install kvm says: No package kvm available. Nothing to do This machine is a CentOS release 5.10 (Final) with the 2.6.18-371.11.1.el5 kernel. Also, the docs related to C5 on http://wiki.centos.org/HowTos/KVM seem to be terribly outdated. What am I missing here? TIA, :-) Marko

rsyslog does not log on a separate partition/FS mounted on /var/log/
by Arun Khan 07 Aug '14

07 Aug '14

The system is an AWS Instance based on a community CentOS 6.4 AMI snapshot. The vdisk is as follows as shown below [1] The root LVM contains /var/log/ I have attached another block device with ext4 FS. I copied the files from /var/log to this device (mounted on /mnt) and then changed /etc/fstab to mount this device on /var/log on boot. However, I do not see anything being logged in /var/log/messages. To test the logging, I used the 'logger' command to log some string; nothing appears in /var/log/messages. 'service rsyslog status' reports the daemon is running. When I stop rsyslog, umount the /var/log device and then restart rsyslog, I can see that logs are being recorded in /var/log/messages. Using the 'logger' command I can see messages written in /var/log/messages. man pages of ryslog.conf and rsyslogd show nothing related to logs being on a separate device Any pointers to fix the problem would be much appreciated.
