Recommendations for webmail client on EL8
by Simon Matter 02 Mar '21

02 Mar '21

Hi all, I'm still trying to find solutions to replace some aging EL6 and EL7 systems. This time I'm looking at email. Postfix and Cyrus-IMAPd are not a problem and also additional things like DKIM are fine. However, I'm wondering what to use to replace good old squirrelmail with. We had a heavily patched squirrelmail with lots of nice things like avelsieve plugin. Since squirrelmail is dead and unable to run on newer PHP, I'd like to use some other tool instead. I was looking at Roundcube but it seems difficult on EL8 because a lot of PHP stuff is missing and not available as RPMs. I guess the same is true for the python things needed for Mailpile. In the end my list only contains Cypht, Rainloop and Afterlogic Webmail lite. Is there anybody running webmail on EL8? Can you make a recommendation on a certain tool? Thanks, Simon

bash: return status of an assignment
by Kenneth Porter 28 Feb '21

28 Feb '21

In the sqm-scripts package for managing network traffic shaping is this line for finding a program suitable for loading the kernel shaping modules: [ -z "$INSMOD" ] && INSMOD=$(which modprobe) || INSMOD=$(which insmod) It seems to set INSMOD to /usr/sbin/insmod, even though /usr/sbin/modprobe is available. (Both are symlinks to ../bin/kmod.) According to this article, the return value of the first assignment should be success and it shouldn't take the fallback statement: <https://unix.stackexchange.com/questions/270828/how-is-the-return-status-of…> Also working the issue here: <https://github.com/tohojo/sqm-scripts/issues/133>

How to install XFCE on CentOS 8?
by Simon Matter 27 Feb '21

27 Feb '21

Hi, Is anyone here running XFCE desktop on CentOS 8? If so, how did you install it? I just tried to install it from EPEL and this is what I got: # dnf group install Xfce Last metadata expiration check: 0:14:01 ago on Thu 11 Feb 2021 10:05:47 CET. No match for group package "NetworkManager-gnome" No match for group package "thunar-archive-plugin" I'm unable to find packages for NetworkManager-gnome or thunar-archive-plugin anywhere in CentOS 8 or EPEL 8. Did I miss something? Thanks, Simon

menu apps like make menu config
by Christopher Wensink 26 Feb '21

26 Feb '21

Good morning everyone, While vi, cat more or less can work (see what I did there..) for looking at every day Linux Administration, sometimes I think it's just easier to work with a menu based interface, where you can select and navigate messages and options, with a little bit of color, possibly function key interaction, and a working interface, similar to using make menuconfig for compiling the kernel and similar to performing a legacy text based install on a new system. Is there a master list of those kinds of apps that have a menu for looking at various things? Can anyone who thinks of more of these apps rattle off some other options such as: abc - for reading logs xyz for text based chat def - for a menu based browser ghi - for a text mail client, etc -- Christopher Wensink IS Administrator Five Star Plastics, Inc 1339 Continental Drive Eau Claire, WI 54701 Office: 715-831-1682 Mobile: 715-563-3112 Fax: 715-831-6075 cwensink(a)five-star-plastics.com www.five-star-plastics.com

OpenStack Training Recommendations
by Paul Heinlein 24 Feb '21

24 Feb '21

Our team at work is looking for OpenStack training options. The training should cover * overview of widely used OpenStack services * network architecture * installation and configuration * ongoing administration, maintenance, and troubleshooting * upgrading We'd prefer workflows based around Puppet or Ansible, since we know those tools, but operational continuity is more important than the tools used. We'd likewise prefer solutions oriented toward CentOS or RHEL, but, again, it's just a preference. We've investigated kolla-ansible for deployment, but we're not adverse to changing toolsets if the upside is right. I'd characterize our team as journeymen to expert system administrators. We specialize in supporting research groups. The training would be to provide skills and knowledge for our team to support OpenStack as a long-term in-house virtualization option. I'd love to hear your first-hand experiences with any specific training offerings. Thanks! (Note: we have other virtualization solutions in place. OpenStack is specifically required by researchers whose wider scientific communities have built workflows for that environment. Suggestions to ditch OpenStack for OtherGreatSolution will be ignored.) -- Paul Heinlein heinlein(a)madboa.com 45°38' N, 122°6' W

Hello, On a remote server (in an IPv6-only infrastructure) I am getting the following error when trying to update CentOS 8 Streams x86_64: $ sudo dnf upgrade --refresh Failed to set locale, defaulting to C.UTF-8 CentOS Stream 8 - AppStream 0.0 B/s | 0 B 00:16 Errors during downloading metadata for repository 'appstream': - Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=AppStream&i… [Failed to connect to mirrorlist.centos.org port 80: Permission denied] Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=AppStream&i… [Failed to connect to mirrorlist.centos.org port 80: Permission denied] Trying to retrieve the mirror list with wget gives similar errors (see log below). This is a development VM and I was playing with firewalld zones on this interface (drop, block, etc.) in order to see the most restrictive that I could use in order to update a system. But the error also appears if I switch back the zone to public. Could it be that my address has been blacklisted because of all these tests? >From my laptop, also running CentOS 8 Streams, everything is working as expected. Thank in advance for hints on how to analyze further!

Date question
by Jerry Geis 18 Feb '21

SO from the man page on date I can do current=`TZ=":America/Indianapolis" date` echo $current current=`TZ=":America/Los_Angeles" date ` echo $current And I get correct data. LA is 3 hours earlier. But doing this: current=`TZ=":America/Indianapolis" date +%s` echo $current current=`TZ=":America/Los_Angeles" date +%s` echo $current I get the same data - its not 3 hours different. What am I not doing correct ? Thanks, Jerry

Using C7 as host to C5 guest
by Jerry Geis 17 Feb '21

Hi all, I am using C7 as a host to a C5 image. This used to boot. I tried today to boot up the C5 image and it get stuck now on the boot screen. Any thoughts on why ? It stuck on the screen that shows root (hd0,0) Filesystem type ext2fs partition type 0x83 kernel /boot/vmlinuz-2.16.18-402.el5 Then nothing... I know C5 is way out of date - but have a couple places still using it. Thoughts on getting this to boot up ? Jerry
