Installing SOGo on Centos 5
by Nikolaos Milas 14 Feb '13

14 Feb '13

Hello, I was following directions at: http://www.sogo.nu/english/support/faq/article/how-to-install-sogo-and-sope… to install SOGo on CentOS 5.9 and, noticing that among the dependencies is memcached and rpmforge includes a much more recent version than EPEL, I preferred rpmforge and therefore I set a higher priority for rpmforge repo (see below). [Note: I guess I could have left out epel in the first place, because I saw that no package was used from there, yet I thought I should follow the directions at the above page, which claim that epel should be enabled, just in case.] So I did: # yum --enablerepo=rpmforge,epel,rpmforge-extras,sogo-rhel5 install sogo sogo-devel sogo-debuginfo where I have the following priorities set: [base] priority=1 enabled=1 [updates] priority=1 enabled=1 [addons] priority=1 enabled=1 [extras] priority=5 enabled=1 [centosplus] priority=6 gpgcheck=1 enabled=0 [contrib] priority=15 [rpmforge] priority = 2 enabled = 0 [rpmforge-extras] priority = 2 enabled = 0 [epel] priority=5 enabled=0 [sogo-rhel5] enabled=0 priority=3 but I got: ... perl-AnyEvent-5.340-1.el5.rfx.x86_64 from rpmforge-extras has depsolving problems --> Missing Dependency: perl(Net::SSLeay) >= 1.33 is needed by package perl-AnyEvent-5.340-1.el5.rfx.x86_64 (rpmforge-extras) Error: Missing Dependency: perl(Net::SSLeay) >= 1.33 is needed by package perl-AnyEvent-5.340-1.el5.rfx.x86_64 (rpmforge-extras) However, it seems an RPM is available at rpmforge-extras (and is > 1.33): # yum --enablerepo=rpmforge,rpmforge-extras,rpmforge-testing info perl-Net-SSLeay ...

Why this package isn't being used during dep solving? Any ideas? Am I doing something wrong? Please advise. Thanks, Nick

First, I am a *nix heretic. Second, I have been using one form of Redhat or another since v5.2 c.1999. For the past 11 years or so I have used Webmin (shielded through IPTables for those horrified at the security implications) to administer my servers, both local and remote. I simply could not get my job done in the time available without it or something much like it. The CLI of the underlying utilities is the final arbitrator of course and there 'man <utility_name>' is your ever-present friend (usually). Nonetheless, the syntax of even the most common *nix commands is often arcane and similar utilities frequently have such subtly different variations that ones mind is sometimes driven to distraction with the inconsistencies. A GUI, whether web based or not, at least clears away that problem for many routine tasks. In any case you will be forced to learn the cli for some utilities from the outset because there is no safe way of using them otherwise. And situations will arise where knowing how to creatively combine utilities with pipes on the command line will save a great deal of time and trouble. A GUI will never give you those opportunities. But for most day-to-day stuff a GUI saves a considerable amount of effort and prevents a great deal of error. Both of which for a newcomer to Linux are of great value. As others suggested, having a test server for experimentation is a really, really good idea. I tend to fire up guest instances on my kvm desktop for such 'proof of concept' trials but I suppose any crash-and-burn system would suffice. Good luck and welcome.

Eclipse CDT not working properly
by Toralf Lund 14 Feb '13

14 Feb '13

Hello again, Another problem with my new CentOS 6 installation: The C/C++ support in Eclipse seems to be partial or missing - even though eclipse-cdt is installed. Eclipse starts all right, and I get a C/C++ perspective, but: 1. If I open a C++ file, it's sent to an external editor. 2. C or C++ is not mentioned in Preferences. 3. I can't find a reference to CDT under Help->About Eclipse Platform->Installation Details I've tried reinstalling all the eclipse packages, and also resetting the workspace as well as the settings in ~/.eclipse, but it made no difference. On startup I get the following messages: CompilerOracle: exclude org/eclipse/core/internal/dtree/DataTreeNode.forwardDeltaWith CompilerOracle: exclude org/eclipse/jdt/internal/compiler/lookup/ParameterizedMethodBinding.<init> CompilerOracle: exclude org/eclipse/cdt/internal/core/dom/parser/cpp/semantics/CPPTemplates.instantiateTemplate CompilerOracle: exclude org/eclipse/cdt/internal/core/pdom/dom/cpp/PDOMCPPLinkage.addBinding CompilerOracle: exclude org/python/pydev/editor/codecompletion/revisited/PythonPathHelper.isValidSourceFile CompilerOracle: exclude org/python/pydev/ui/filetypes/FileTypesPreferencesPage.getDottedValidSourceFiles Has anyone else seen this? Any idea what's wrong? Is anyone here are using Eclipse for C++ development, anyway? Eclipse platform version is 3.6.1-6.13.el6.x86_64, CDT 7.0.1-4.el6.x86_64 (those are the latest from updates.) - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.

pcl to pdf
by Gregory P. Ennis 14 Feb '13

14 Feb '13

Everyone, I am currently using a vsifax program (pcltotiff) to convert pcl files to tiff files on a SCO Unix box, and then I am using tiff2pdf on a Centos 5.9 box to convert the file to a pdf. There are other commands that deal with multiple page tiff's and pdf's that are part of the process, but the above basic process has worked very well. The only thing I would like to enhance is a better resolution of the tif file and therefore the pdf file; the problem being the resolution capability of pcltotiff that comes with vsifax. I am limited on the SCO box as to what I can install; it is too old to admit to, and is scheduled to be upgraded to a new Centos system. Obviously, I can get the pcl file to the Centos system easily, do any of you have suggestions of being able to convert a pcl file to pdf on the Centos system. Greg Ennis

selinux and tinydns
by Philip Manuel 14 Feb '13

14 Feb '13

Hi all, tinydns starts up fine, selinux reports no issues (now after a day of clearing errors). If I turn selinux back to permissive in /etc/sysconfig/selinux, and reboot, tinydns responds to queries. If I turn selinux back to enforcing and reboot, tinydns does not respond. Monitoring /var/log/messages shows no errors from iptables/shorewall or selinux. The only way I can find an error is performing the following:- netstat -npl | grep tinydns # gives me the process id strace -f -p <process id> From this I can see that tinydns is reporting an error of:- recvfrom(3, 0x606720, 513, 0, 0x7fffc7321ec0, 0x7fffc7321edc) = -1 EACCES (Permission denied) I've got setroubleshoot set to send me an alert on first occurrence of an issue, so far none received. Does anyone know how I should proceed from here ? Thanks Phil.

check file changes within several directories
by Mihamina Rakotomandimby 14 Feb '13

14 Feb '13

Hi all, I forgot the name a sofware (I think it was something related to security) wich checks for file content/permission changes, on a cron trigger basis. I could then have the list of added/changed files. I dont want to use some selfmade git-based or "find|xargs"-based piece of scripts. Thank you. -- RMA.

Overdue upgrade of bind
by Robert Moskowitz 13 Feb '13

13 Feb '13

I am **FINALLY** starting in on upgrading my domain server. Right now it is still on bind-9.3.6 via Centos 5.5. Stepping right up to 9.8.2 in Centos 6.3. I am pretty good with zone files and the like, though I will finally get to tackle DNSSEC (and I can go to the sources Austien, Vixie, and Liu if need be or even the bind list!), but right now I have much more mundane issues. Like it looks a bit like the chroot tree has changed! In particular under /var/named/chroot/etc I use to put my named.conf with all the include files. Now I see sub-directories named and pki there. I am ASSuMEing that pki will be for the DNSSEC; but where is the documentation? I tried looking for readme files, but can't find anything related to the chrooted bind environment. What file is the location of named.conf set up in? The zone files look to go in the same place I have them on the old server under /var/named/chroot/named/var/named.
