40_custom be the default option
by Jerry Geis 18 Nov '19

18 Nov '19

Hi All - I have my 40_custom file setup. What is a good way to make that the default boot option ? I'd rather not count menu option lines and change GRUB_DEFAULT to that - as I am doing this remote. Thanks Jerry

I'm not looking for a 'per-script' solution. Logging when a job starts is performed by crond, so logging when it ends should also be done by crond. Despite the article I mentioned being from 2011, it seems that Debian 10 still supports the logging of when cron jobs end. Looking into this further it seems that Debian uses anacron, and then applies a patch which provides the '-L' option. I have raised this with the cronie project on github to try and see why this feature has not been implemented. (It may well be that there are good reasons for it having not happened.) A very quick look at the cronie code seems to indicate it may be possible to implement.

Place to run script command for all user/sessions
by Erick Perez - Quadrian Enterprises 16 Nov '19

16 Nov '19

Hi all, I would like to record user commands in terminal mode for remote supporters. I currently do that with the command "script - make typescript of terminal session". So far so good as long as I run a combo os screen/script at the command prompt, allow remote worker to control screen session and then at the end I do ctrl-d to save the script session. This however do not work (or at least is not practical) when I want to allow someone to login via SSH directly and unattended. What will be the place to insert "script" in order to call it for each login/logoff and sudo executions? As an alternative for my fellow coworkers I have setup a Windows 10 PC with putty and Teamviewer/AnyDesk on it. Remote supporters go into the Teamviewer/AnyDesk pc and then SSH using putty into the specified Linux box. Putty is setup as to record the entire session automatically. Linux boxes dont have GUI. Linux Boxes are Centos 7 x64 and only 3 are Centos 8 x64. Thanks for your comments. -- --------------------- Erick Perez ---------------------

Cron - log when job ends?
by John Horne 16 Nov '19

16 Nov '19

Hello, In trying to resolve a problem with a cron job, we can see when the job starts by looking in the /var/log/cron log file. However, I was asked if when the job ends could also be logged. (It seems to be something that crops up every so often over the years.) I found on the 'net this article https://serverfault.com/questions/248915/crontab-is-there-any-log-with-begi… which mentions a loglevel (-L) option, and by setting this to 2 it will log when a cron job ends. It sounds great, and just what we could use. The downside is that there seems to be no such option anymore. The article is several years old but the users says they are using anacron. Checking on both a CentOS 7 and Fedora 31 system, which both use cronie-anacron, I could find no mention of any loglevel. Does anyone know what happened to this option (why it was removed)? It would seem to be useful, but removed at some time. Thanks, John. -- John Horne | Senior Operations Analyst | Technology and Information Services University of Plymouth | Drake Circus | Plymouth | Devon | PL4 8AA | UK ________________________________ [http://www.plymouth.ac.uk/images/email_footer.gif]<http://www.plymouth.ac.uk/worldclass> This email and any files with it are confidential and intended solely for the use of the recipient to whom it is addressed.

C8 Questions
by Alessandro Baggi 16 Nov '19

16 Nov '19

Hi all, I've several questions about C8. I'm using 8 on my personal NAS and works very well. I'm running several VMs with centos 8 and noticed something: 1) Why corosync, pacemaker and pcs are missing on C8? They are only available on rhel with payments( rhel ha addons)? 2) Why there is only Gnome as available DE? I use centos on my workstation and I'm a kde-plasma user. XFCE is ok but not gnome. I tried fedora, it has all software that I need and it is a very good distro but I don't like too much update and its EOL (upgrade/reinstall every 13 months on a workstation is not so good for me). I don't want to be forced to install another stable distro like debian (This not means that debian is bad but I prefer centos). 3) I have a VM with C8 installed. I got several updates but I don't receive any update for 8 on centos-announce like for previous versions (6 & 7). Something has changed? 4) EPEL. I know that EPEL is a Fedora SIG but I use several packages from EPEL. There is a place to see what packages will be included in EPEL? For example, I tried to install audacious from epel but got errors for missing deps. Seems that EPEL8 is released but not ready. There is a ETA for this? 5) It's my impression or there are less packages in this release? 6) Why cockpit installed by default? 7) Why repo PowerTools was created? What is the main purpose? 8) Why NetworkManager is the default method to configure interfaces? I know that I can install network-scripts but I don't understand this change. Best regards, Alessandro.

how to know when a system is compromised
by Christopher Wensink 15 Nov '19

15 Nov '19

How do you know when a Linux system has been compromised? Every day I watch our systems with all the typical tools, ps, top, who, I watch firewall / IPS logs, I have logwatch setup and mailing daily summaries to me and I dive deeper into logs if something looks suspicious. What am I missing or not looking at that you security gurus are looking at? I subscribe to the centos and SANS newsletters, and I try to keep current on all technology with credible sources of articles online and with the Lynda library. What other sources of information do you use to stay current about the latest threats and technology updates? I appreciate the feedback. Chris
