The problem I think was that the syntax was one which worked for one OS and the dracut is meant to work for all Linuxes.. so they worked out a set of items which worked for Debian, SuSE, Mandrake, Fedora. The syntax change I think landed in Fedora right after RHEL-6 and was in RHEL-7 from the beginning. As the web page goes over, there are several different syntaxes which can be used for different environments.

The mac address isn't mandatory but you are then up to the whims of
the kernel, dracut, and whatever else is involved on what gets picked
for eth0. It works less often than it used to for me so I would end up
on a very very long rant tag.

That method was listed as deprecated in EL-7 and I think the method
you need to use now is
http://man7.org/linux/man-pages/man7/dracut.cmdline.7.html

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.

[CentOS] Cron - log when job ends?
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-begin-and-end-time 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.

[CentOS] udev on CEntOS7 - can't get a match, looking for tips...
The mtx binary requires my tape library to be assigned a sg# driver, but
the kernel periodically renumbers the sg devices. Normally, we would
write a udev rule to manually assign a persistent name, but it looks
like things have changed as I can't seem to get a match on CEntOS7. I'd
appreciate any feedback or pointers to help me get my rule working. My
two attempts are below.
cat /etc/udev/rules.d/90-local.rules
KERNEL=="sg[0-9]*", SUBSYSTEM=="scsi_generic", \
ENV{ID_SERIAL}=="1QUANTUM_D0H0112430_LLA", SYMLINK+="sg8"
SUBSYSTEM=="scsi", SUBSYSTEMS=="scsi_genric", \
ATTRS{model}=="Scalar i40-i80 ", SYMLINK:="sg8"
Neither rule above generates a match with udev, so I still have
something wrong. Right now the assignment is sg7 (but it's had other
names in the past.

It is good to do re-installs regularly to avoid problems like whatever
file-system in Fedora N does not work with containers (or some other
new feature).. but the Fedora N+1 filesystem does. You can only get
that availability by reinstalling or creating a new file-system which
you put stuff into... so in many ways a fresh install is usually good
to do every 4-6 releases so that you aren't debugging 'why doesn't
this new utility work'

I think you need to give a lot more explanation on what is going on because I (at least) have no idea how you are using a non-shipped text editor . Usually if a tool is not giving similar results...

That is how Red Hat ships the product. I expect that it is not a default stream because of internal rules on what is a default stream or not. [My guess** is that default modules can not be updated 'rapidly' so if FreeIPA 8 were shipped in 8.0 it would need to be long term maintained but if it is shipped as a non-default they can put out a FreeIPA9 whenever they wanted to.] ** While I work at Red Hat, I do not know what the rules for default/non-default are.

The ip commands have been around since Centos 6 if not earlier. you can do things with them that you can't do with ifconfig, such as setup policy routing rule sets..

There are multiple scenarios that you could be trying that meets that sentence, and some of them would be possible and others would not. Some scenarios will try to use the hardware UEFI to store variables and that will cause problems because the virtual systems will conflict when talking to the hostservers hardware (I think this would come up with certain secureboot scenarios but not sure).

The reasons I could see for very very slow nvme would be that something is trying to write too small a sector for the drive and flushing the drive. Depending on the nvme it might be set up to read mostly and write rarely, read/write even or write a lot/read in blocks. VM's usually are mixed use and get really weird behavior on the others. If the nvme is expecting large writes and it is getting small ones which don't "fit" it will 1) wear out the nvme because it is basically rewriting a full block every time even if it is only changing 5 k and 2) is slow because all those little writes are blocking.

Hi, Because RHEL releases are far apart, packages don't get automatically added to newer EPEL releases. Instead, packages are usually added after maintainers get a request through bugzilla. This allows the packager know that the software is needed and also to see if they have time to support another branch. I don't see the tool being deprecated in Fedora so it should be possible.

Having spent more time than I want dealing with systems which seem to be just like everything else but coming up with eth0 being eth4 (I am looking at you 40 Dell, HP and IBM boxes) on a reboot half the time.. I have come to see that a lot of scripts are full of race conditions and slowdowns to try and stop those race conditions from happening. If anything messed up from a kernel change, bios update, a switch update?, etc and you could be completely in the weeds wondering why imperative was failing. It was failing because it was never absolutely true. The problem is that as hardware rollouts have grown larger and larger spending time trying to figure out why 400 to 1000 out of 10,000 systems are weird.. is too much time. You want something which will try to figure it out itself and do the 'right' thing.. even if it means that eth4 on those 400 boxes are now the main interface versus the eth0 on the 3600. And yes.. as an non-neurotypical person.. I find that incredibly infuriating.. however I have also realized that most businesses don't care I and others find it that way.

One of which is: > It is the same evolution you see in other industries. Auto mechanics constantly complain about how the newer generation is 'dumber' for not knowing the beauty of a vehicle that the mechanic had when they were in their teens. [Of course they also rail on the fact that their grandparents car was a complete junk that was too simple to work.] Most of the tools we had 30 years ago in computers are like working on a Model T era vehicle. They allowed for a lot of configuration choices and fine tuning but they also were limited vastly in other ways. You can't run a fleet of 1000 Model TT trucks made in 1923 as well as you could 1000 1933 trucks. You ended up losing some of the knowledge of hand-crafting your own gears but you got the ability to go faster, carry heavier loads and better gas mileage without working as hard at getting a mile out of a quart. The transmissions of the 1933 were considered 'automatic' compared to some 1912 vehicles.. even if you had a clutch because you no longer had to get out and turn something to make it go in reverse. The 'truly' automatic transmissions of the 1950's were horrible and it wasn't until the 1970's where they became 'liveable'. Today trying to find a real stick shift is almost impossible as you find out that the most are really talking to a computer which does the shifting when it decides is optimal. As that happens the place where a programmer makes changes goes higher and higher. They no longer see a system by itself but see 10,000 nodes sitting in some cloud. They really could care less if 10% of them drop off because there is a tool which is going ot bring 1000 back online when that happens. However they may still be worrying about making a change 'low' level to them. It is just light years above where those of us with only 10 or a 100 systems can dream about. -- Stephen J Smoogen. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Thus even though you have the same source code, similar compilers etc.. there are going to be differences which have to be looked at to make sure it is really working. A CentOS kernel is not exactly the same as a RHEL kernel is not the same as a Oracle kernel is not the same as the one you recompiled locally. From most operational points they seem the same, but kernel patching is where those differences really show up. Yes it would be easy to set up some automated tool which 'made' kpatches.. and I expect they may 'work' for most systems. But I also expect that they would also eat babies more times than people would like. If sites really need them, they can set up the tooling themselves and make them work when they know they want it. Trying to make it a general purpose answer for something which may corrupt data 5 or 20% or 40% of the time.. is just waiting to be on Slashdot daily (wait do we do Slashdot anymore..

HOWEVER, the /etc/ssh/ssh_config will tell you that this is only last default: # Configuration data is parsed as follows: # 1. command line options # 2. user-specific file # 3. system-wide file # Any configuration value is only changed the first time it is set. # Thus, host-specific definitions should be at the beginning of the # configuration file, and defaults at the end. If the user sets things differently on the command line or in their .ssh/config file.. it will override your defaults. Another thing.. to determine how the policies are set, I would recommend reading through those config files. They will say that they are looking to include data in /etc/ssh/ssh_config.d/* which has /etc/ssh/ssh_config.d/05-redhat.conf on my system. Going into that.. it says it will attempt to Include /etc/crypto-policies/back-ends/openssh.config which will be pointing to the file you want. Since htat file might change in an update, you may want to override settings by putting the defaults you want in 01_site_defaults.cfg which would then get read in before 05-redhat.conf and be the ones to use. -- Stephen J Smoogen. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

You have to determine that you have a working kpatch (you can have one which works on 1% and corrupts 80% and crashes 19%), you have to determine that the patch fixes the problem (you can build patches which should do the right thing but don't), and you have to determine that it doesn't add in some sort of long term corruption of memory/disk/etc. That takes specialized kernel expertise, a large amount of varied hardware to test the patch on, some amount of time, and a very large test suite. You can also only live patch a system so many times and in only certain places. There are just some parts of the kernel which have to be rebooted and others you can put in a patch which works but your performance is going to be 25% of what it was before. There are other places that if you patch.. that is it.. try another and you hardlock. As much as some sites like to call it some sort of panacea for never having to reboot again.. it is really meant to be a tourniquet to air chopter the crash victim to a hospital.

So you end up with a circle of finger pointing where the user points to the OS manufacturer. The OS manufacturer points to the hardware. The hardware will point to the user for using the hardware outside of its specific 'recommendations' which you thought was a EULA. After a long set of time.. no one is happy and a lot of money/time was lost on something which can't be fixed. So the hardware gets dropped from the OS vendor's supported line to stop the circle.

The package is built inside a module and the -devel is a 'build-only' tool which doesn't get out of the build system. This is mainly because the libssh2 is only in there to make an app work which I think is being rewritten to use libssh but didn't make it in time.

Upgrade programs are usually tested for each Unix and Linux in the following manner: For A in Arch; do For B in Hardware-Type; do For X in Oldest_Supported_Major to Youngest_Supported_Major; do For Y from Oldest_Support_Minor to Youngest_Supported_Minor; do Install the OS-X.Y from original media. (maybe) Make changes as listed in manual (if you are lucky) Make known changes which broke major customer last time Run upgrade to OS-N.0 Reboot. If system boots; Pass else Fail; fi Done; Done; Done; Done; Fix all the Fails that you can.. or document that they can't be fixed in tech support. That still probably takes several QA people days of work to go through for an upgrade. Most systems that are lived in quickly fall outside of the scope of what the upgrade tests can find OR what the upgrade program can determine what to do. This is the main reason why you should do a rollout of a new operating system with a plan beyond yum --upgrade-system --YOLO So to make it work, what you normally have to do is continually treat your system like it could be nuked at any moment and you need to rebuild it from whatever is latest. That takes a lot of controls and work which most of us don't have time for.

Problem with rsync clones, they are asynchronous each file is copied separately so if the system is live and making changes, for instance a database server, the copy is not coherent. the ZFS file system is perfect for this stuff, you can snap shot and then ZFS send the snapshot or a delta between that snapshot and a previous snapshot and that creates a totally coherent copy made at a single point in time atomically. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

First there is a lack of packages available. Then there is the complaining that the OS is useless because it doesn't have ABC. Then there is finding the people who are challenged enough by the lack of packages to go learn how to package up stuff and make it available. Then there is a section where packages get uniform and together. Then things pretty much stay at that until the next CentOS major release... people either decide they want to skip to the next or just wait it out. So currently we are in the finding out the lack of packages and the complaining stage.

Usually when I run into this sort of issue it usually has to be fixed with an updated ppd driver from the vendor for that printer... usually the one they give to Apple and possibly one that was aimed for the country/area the language is not working on. I would then have to double set the printer with one for Western fonts and one for non-Western using 2 different ppds because things looked wrong one way or another.

USB is usually given a higher connection on the hardware because people get grumpy about mouse jerkiness. Some motherboards will give you multiple USB controllers where you have one which is highest priority so keyboard/mouse doesn't stop and the other is on a lower priority bus for disk transfers. Other motherboards stick them all on the same controller and you end up with everything frozen while a large USB transfer occurs. It doesn't matter the OS you are running when this happens the problems are in the hardware IO controllers and usually can only be 'fixed' by firmware (if you are lucky). [Which is why you can have 2 people with the 'same' motherboard unable to replicate each others issues until you burn them all to the same firmware all through out (and hope the manufacturer didn't change the MB somewhere in the runs.). My next suggestion was similar to what you have below. See if plugging in a different USB port mitigates the issue. If the mother board has a 2-3 vertical stacks, they sometimes have the furthest one from the keyboard on a different bus. Also see what the lsusb and lspci commands say.. they can sometimes point out a helpful hint. > Consider: you may have a gigabit Ethernet connection to the Internet, and > it is probably throttled to a small fraction of that speed by your ISP, yet > you can be pumping hundreds of giga*bytes* per second to your SSD while > your browser is blocked waiting for the remote server to respond.

When that happens your graphical workstation will slow down because your keyboard and mouse events and some other polling has to complete before it can do the next thing.

The hex number is quite large, and too big I suspect for the number of inodes
allowed on the partition.

I was going to say no to both of these, however the RPM package ('xymon') was
itself updated at around the time mentioned on Aug 02.
The hex number is equivalent to 1564754190 in decimal which, as an epoch time,
is '2019-08-02 14:56:30'. So it might be possible that '/usr/sbin/xymond' was
replaced and the hex number just indicates the time that occurred.
The downside is that the package update was a bit earlier than 14:56 though, so
the numbers don't seem to quite match up. Secondly, the whole xymon process was
restarted, but the server itself not rebooted, so I would expect all the
processes to be using the new executables rather than an older/deleted one. (I
am a little loath to restart the service at the moment as I may well lose the
info currently in '/proc/.../exe'.)
John.

I tried the minimum install and got the same result. Hard to diagnose an unresponsive machine.

[CentOS] Installation question?
I've been doing a CentOS 7.6.1810 net-install since last night. The machine seems ok but has been stuck with "performing post-installation setup tasks" for hours. This is an old Dell T5400 box, so it isn't blazing fast but ... Is there a way to pull up its skirt (so to speak) and check/monitor the installation activity while installing it? Having already started the installation? BTW, in the phase of the install process, is it still hitting the net? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

The problem is that encrypted servers initrd.img have the ip addresses set in them. I am not sure why it happens.. but it does.. I had to manually edit the initrd.img and find all the places where the old ip addresses were mentioned to make it work. You can't just make a new initrd because it copies these configs over from the previous one.
