mailgraph pages are in German
by Robert Moskowitz 24 Feb '17

24 Feb '17

I was pointed to mailgraph, and it looks kind of interesting. So I installed the rpm, only to find that it comes up in German. The German is hard coded into places like: /usr/share/mailgraph/mailgraph.cgi Anyone know where I can get an English version? thanks

help with RewriteRule regexp
by Robert Moskowitz 23 Feb '17

23 Feb '17

My regexp skills are somewhere infinitesimally close to zero. I have never really 'gotten' them. That said, I have spent a couple hours already search for help to write a rewriterule that works on a string in the URL. In particular I want success if either of the following were provided: webmail.domain (e.g. webmail.foo.com) server/webmail (e.g. www.foo.com/webmail) And I have not found anything like this, nor do I know even close enough of regexp to recognize something like this in another expression. Thanks for the help.

Centos7 whatprovides php-imap
by Robert Moskowitz 23 Feb '17

23 Feb '17

Would someone with a Intel Centos7 installation PLEASE find out for me: yum whatprovides php-imap Something is broken in my Centos7-armv7hl install, and I can't figure out what is broken without knowing where it is. Actually the warning I am getting is about php5-imap, but I suspect that in C7 it is just php-imap. thanks

Problems installing packages from the CD
by Mauricio Tavares 23 Feb '17

23 Feb '17

So I did a minimal install of centos 7 vm guest just to find out it did not install perl. Since as of right now I have no properly functioning network on that machine (different issue; we can talk about that in another post), I went for the next best thing: install CD. I grabbed the CentOS-7-x86_64-Everything-1611.iso CD (around 8GB), attached it to the guest, and mounted it on /mnt. Then I edited the cat /etc/yum.repos.d/CentOS-Media.repo # CentOS-Media.repo # # This repo can be used with mounted DVD media, verify the mount point for # CentOS-7. You can use this repo and yum to install items directly off the # DVD ISO that we release. # # To use this repo, put in your DVD and use it with the other repos too: # yum --enablerepo=c7-media [command] # # or for ONLY the media repo, do this: # # yum --disablerepo=\* --enablerepo=c7-media [command] [c7-media] name=CentOS-$releasever - Media baseurl=file:///mnt/ gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 I then run yum clean all and then decided to look for perl only on the cd repo, i.e. yum --disablerepo=\* --enablerepo=c7-media search perl It gave me back the pcre package, which is already installed. I did check the /mnt.Packages dir and there are plenty of perl-related packages including itself. yum --disablerepo=\* --enablerepo=c7-media list all shows only installed packages, some of which are shown (?) to have been installed from c7-media.

OT: hardware, IBM 3650 M2 won't power on
by m.roth＠5-cent.us 23 Feb '17

23 Feb '17

I've never seen anything like this. We moved it from the data center yesterday, and this morning I plug it in, and it won't power up. I find a manual for it online, and it says that on plugging it in, wait 3 minutes. The power button will flash 4x/sec, then slow down to once a sec, and at that time you can power it up. Well, it never stops flashing at 4x/sec. I've connected a network cable, wondering if it's in wake-on-lan; I've tried connecting to it via its management port, and *zip*. I'm not going to do, as several folks' posts that I googled (been at that for hours), cut the cable and solder in an on/off switch. I have taken the lid uff, reseated the PSUs, and the cable connecting to the front panel, and nada. Anyone got any ideas? mark

BOINC
by Alessandro Baggi 23 Feb '17

23 Feb '17

Hi list, I've installed boinc-client and boinc-manager from epel. After starting boinc-client with systemctl when I try to connect from boincmgr I get "Unable to connect to boinc client". I've added to unit file --allow_remote_gui_rpc and on netstat I get: tcp 0 0 0.0.0.0:31416 0.0.0.0:* LISTEN 4762/boinc_client On this machine there aren't iptables rules I've also added my current user to boinc group without success. I've tried also to run boincmgr from root without success. Reading from https://boinc.berkeley.edu/wiki/Client_configuration I've not found any usefull config parameters to save in /var/lib/boinc/cc_config.xml Selinux is Disabled. I've tried also to run from a root shell: /usr/bin/boinc_client Running the manager from root I can connect to the client but from simple user I cannot. So I don't understand where is the problem. What I can do to solve this problem? Thanks in advance.

question about directory size in linux..

on a CentOS release 6.8 (Final) I was looking around and noticed the following in a directory. [jason@server /app-vol/applications/]$ls -ld temp drwxr-xr-x 4 jason users 2899968 Feb 18 06:31 temp/ [jason@server /app-vol/applications/]$ How does the directory *itself* have a size of 2.8 megs? yes the contents in that temp directory add up to 2.8 megs, but.. umm. huh? when I run a stat on the temp directory, i get File: `temp' Size: 2899968 Blocks: 5672 IO Block: 4096 directory Device: fd02h/64770d Inode: 1836137 Links: 4 Access: (0755/drwxr-xr-x) Uid: ( 1022/ jason) Gid: ( 501/ users) Access: 2017-02-22 06:31:51.414190071 -0500 Modify: 2017-02-18 06:31:56.135448424 -0500 Change: 2017-02-18 06:31:56.135448424 -0500 on other "normal" directories, I see something like Size: 4096 Blocks: 8 IO Block: 4096 directory Jason
