Skype on CentOS 6.5
by Mark LaPierre 19 Aug '14

19 Aug '14

Hey Y'all, About a week ago my Skype installation stopped working. I can start it up but I can't log on. Does this have something to do with the recent update to LibC? Is there a repo som where that has the latest version of Skype for CentOS 6.5? When I go to the Skype web site I see that there is a version several versions newer available for RPM based Linux but that one won't even start. Can anyone offer some sound advice to getting my Skype running again?

Upgrade to m7.0 retaining some existing partitions
by Tony Molloy 19 Aug '14

19 Aug '14

Hi, I want to install 7.0 replacing an existing 6.5 installation. When I choose custom partitioning I can delete the old 6.5 partitions and create new partitions 7.0 but there doesn't appear to be any way to retain an existing partition, say /home for instance, over the installation. Am I just missing something obvious or any ideas on what the magic is. Regards, Tony -- Linux nogs.tonyshome.ie 2.6.32-431.23.3.el6.x86_64 #1 SMP Thu Jul 31 17:20:51 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

need-restart ?

19 Aug '14

Hi, today I updated the glibc packages on some CentOS machines. After the Update I checked which services/processes I have to restart "yum -C ps" or "needs-restarting" At the most machines I get no information about necessary restarts, but at two machines a long listing : 1 : /sbin/init 386 : /sbin/udevd-d 659 : /sbin/udevd-d 999 : /usr/sbin/vmtoolsd 1103 : auditd 1128 : /sbin/rsyslogd-i/var/run/syslogd.pid-c5 1170 : rpcbind 1188 : rpc.statd 1229 : dbus-daemon--system 1270 : /usr/sbin/acpid 1279 : hald 1280 : hald-runner 1325 : hald-addon-input: Listening on /dev/input/event2 /dev/input/event0 1329 : hald-addon-acpi: listening on acpid socket /var/run/acpid.socket 1350 : automount--pid-file/var/run/autofs.pid 1366 : /usr/sbin/mcelog--daemon 1386 : xinetd-stayalive-pidfile/var/run/xinetd.pid 1486 : /usr/sbin/abrtd 1494 : crond 1505 : /usr/sbin/atd .......

restarting the CentOS office hours
by Karanbir Singh 19 Aug '14

19 Aug '14

Hi Guys, For a few weeks we ran the CentOS officehours, that were fairly well recieved. And now that CentOS-7 is out of the door, it would be good to restart those again, and perhaps focus on conversations wider than just about the Project and the SIG's process. We should do those too, but we should perhaps also consider including technical content and howto's etc. Would there be interest in something of this nature ? Also, I'm looking for some help to organise and run these office hours, so please get in touch if you are able to spare an hour or so every now and again to help with this effort. regards -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Use postfix and spamd on CentOS 6 - looking for a shortest guide
by Alexander Farber 18 Aug '14

18 Aug '14

Hello fellow CentOS-users, on the net there are lots of Spamassassin related HOWTOs - describing how to create a shell script for Postfix and how to install Spamassassin and start its spamd daemon - step by step. Additionally antivirus setups are described... But I have a strong feeling, that this is unneeded on CentOS 6 - because there are already preconfigured stock packages for postfix and spamassassin. So I have installed the both packages and I have configured postfix (it works fine). Also I have started the spamd (and can see it in "ps uawx") with: # chkconfig spamassassin on # service spamassassin start So I'm just missing the connection between postfix and spamd. Could anybody using these 2 programs on CentOS 6 please share it with me? Should I add something (involving spamc?) into /etc/postfix/master.cf? Thank you Alex P.S. Below is my "postconf -n". I accept mails (here I'd like to filter spam) for 6 virtual domains and then forward them to different GMail accounts: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 header_checks = pcre:/etc/postfix/header_checks html_directory = no inet_interfaces = all inet_protocols = ipv4 mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost myhostname = www.afarber.de newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_destination_concurrency_limit = 2 smtp_destination_rate_delay = 40s smtp_generic_maps = hash:/etc/postfix/generic unknown_local_recipient_reject_code = 550 virtual_alias_domains = videoskat.de balkan-preferans.de simplex.ru larissa-farber.de bukvy.de slova.de virtual_alias_maps = hash:/etc/postfix/virtual

To route messages from origin to destination based on the DNS information relating to the delivery address correct? But SMTP is not intended for message composition, submission, final delivery, display, content checking or any other ancillary operation. And it is these ancillary operations that are the source of much of the complexity and nearly all of the confusion and difficulty experienced with setting up Mail Transfer Agents (MTA). For example, a major problem discussed WRT MTAs is the proper setup of SpamAssassin (SA). People talk about setting up SA to filter mail. But SA does not do that. It simply scores messages as to the relative likelihood that the message contents are UCE/SPAM. Likewise, ClamAV does not filter for virus infection, it simply detects and reports. To filter one must configure the MTA to respond to the reports of SA and ClamAV. And there are many ways of configuring that response. Sendmail uses Milters for example whilst Postfix uses policy daemons. These are fundamentally different approaches to the problem. However, Postfix can also provide a Milter-like interface. Thus the configuration options can get quite extensive and it is difficult to anticipate and describe 'normal' configurations in such a case. Using Amavisd-New (http://www.amavis.org/) with Postfix to configure SA and ClamAv to filter mail worked best for me. Trying to get Postfix to work directly with either proved beyond my ability. Even with Sendmail I found that MailScanner was essential to get SA and ClamAV working together. Given that Amavis and MaiScanner exist for the sole purpose of bolting anti-spam and anti-virus filters into Postfix and Sendmail I infer that most people have experiences similar to mine. The Postfix mailing list at Cloud9 is a good place to get help WITH SPECIFIC POSTFIX PROBLEMS. However, I believe that it would be, shall we say, unwise to ask for hand-held guidance setting up a Postfix MTA on that list. RTFM is perhaps the mildest response one could expect. On the other hand, asking a very specific question about what TFM is trying to say in a particular section usually elicits helpful replies. I suggest that you look at Amavisd-New from EPEL and probably ClamAV from the same source (do not mix EPEL and Repoforge packages in this case) and go from there. I believe that you will find that much easier to work with than trying to use SA directly with Postfix. -- *** E-Mail is NOT a SECURE channel *** James B.

Down-grading to an "obsoleted" package
by Toralf Lund 18 Aug '14

18 Aug '14

Hi, Does anyone know if there is a clean way to "downgrade" to the old rpm package when it was previously replaced by another that obsolete it? I mean, say that I have installed some rpm "A-1.0-1.x86_64.rpm", and along comes "B-1.0-1.x86_64.rpm", whose spec has Obsoletes: A Now, if I do "rpm -U B-1.0-1.x86_64.rpm" or "yum install B-1.0-1.x86_64.rpm" or (if B is available through an enabled repository) "yum update", what happens is that "A" gets removed and "B" is installed in its place. Then I decide I want to switch back to "A". So what do I do? I know that one answer is rpm -e B rpm -U A-1.0-1.x86_64.rpm - but what if A and B provide facilities required by other installed packages? I'll then have to pass "--nodeps" when removing B, but that's something that I really want to avoid as it means loosing control over whether all dependencies are satisfied. So is there an alternative? "rpm -U A-1.0-1.x86_64.rpm" alone seems to fail with file conflicts, assuming "B" replaces some of "A"'s files. In a real scenario I tried, there was no mention of the fact that something that was essentially a newer version of the same package, was already installed. "yum upgrade A" (when the package is available on a repository) fails in a similar manner. "yum localinstall A-1.0-1.x86_64.rpm" is a bit smarter - it exists with a message like "Cannot install package A. It is obsoleted by installed package B". "yum downgrade A" (via repository) says something like "No Match for available package: A-1.0-1.x86_64.rpm". "yum localdowngrade A-1.0-1.x86_64.rpm" would seem to have the highest probability of success based on the above, except that there is no such command :-/ Any other ideas? - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.
