Re: [CentOS] cluster ssh edit file with vi slow
Hi Ralf, That's not something I'd normally consider doing. Is it possible for you to edit just the local file and then use scp to distribute it? OK, you lose the cluster-wide mechanism but it woul be possible to set up a small script to bang off the copies in the background.

Re: [CentOS] Unexpected /etc/resolv.conf updates on CentOS 7
If you just want to tell NM to clear off and leave your resolv.conf alone do the following: If you don't want it to touch the contents of the file then remove all DNSx= parameters from all ifcfg files and add PEERDNS=“no” instead. Now you are solely responsible for setting the content of /etc/resolv.conf yourself. You may also have to edit /etc/NetworkManager/NetworkManager.conf and add dns=none to the [main] section.

I thought that there would simply be an update whenever a connection was established, and an addresses/network info was received (if using DHCP), and that the information would pretty much be left alone after that. However, I've lately found that a new file gets written every few hours even though there is no connection change (that I can detect), i.e. the same link is up all along. Does anyone have any ideas why that might happen? I thought at first that the updates could be linked to DHCP lease renewal, but on closer inspection, that does not seem to be the case. I don't see anything in the system log related to networking at the points where a new file gets written. I get the above behaviour for my home Wifi net. It seemed to start after I switched to a new router, but that might be coincidental. It's a problem for me because I'm also using "commercial" VPN software (not integrated with NetworkManager) that will create it's own resolv.conf file; it replaces data e.g. from Network Manager when VPN is enabled, and restores it on disable. If NetworkManager "refreshes" the information in the mean time, the DNS config for VPN is lost, and the link doesn't work as expected...

Re: [CentOS] external USB drives, strange result on reawaking
I'm sorry but I've moved away from Amanda so can't help. However one thing that your description does imply is that you keep the drives in the enclosure next to the machine. Unless you have some other mechanism for taking a remote backup, this is a bad idea. consider the aftermath of a fire, theft, electrical malfunction or virus infection. Adjacent drives may have either disappeared, melted, had their interfaces ruined or been corrupted. In any case, quite possible no use as backups. Best practice is to ensure that periodically a good backup (equivalent of a level 0) is taken and stored offsite. For domestic users that might be stored in a safe elsewhere, but offsite is the ideal. Sorry to nag, but better to act now than when you are faced with a new insurance replacement and no useable backup. Martin.

Re: [CentOS] Auditing all Linux clients with centralised server
A cut-and-paste from my Wiki: ---%< Remote logging Auditing, particularly from compute nodes, may be centralised to reduce the number of files needed to get a view of the cluster. Server The server machine must be configured to accept messages and must have a large enough logging area to store the records. The server listens on port 60. Configure this as tcp_listen_port in /etc/audit/auditd.conf. The server must only accept messages from a privileged port. If this is not done any userland process could inject nefarious messages. It is safe to configure the server to accept messages from any privileged port: tcp_client_ports=1-1023 in /etc/audit/auditd.conf. On the server increase tcp_listen_queue to 16 to ensure enough requests for connections can be handled during a power-on bootup. You will need to restart the daemon for these changes to come into effect. Clients The client machines may either forward messages at once or else batch them up in a queue. Generally machines with local storage should use the queue which preserves the log in the event of a crash. You will need to restart the daemon for all these changes to come into effect: systemctl restart auditd. Ensure the appropriate software and configuration is loaded: # yum install audisp-remote. /etc/audisp/audisp-remote.conf The client needs to know where, and to which port to send messages. As mentioned above, the client must send from a privileged port. remote_server= port=60 local_port=61 On diskless clients set mode=immediate, on other clients set mode=forward. Accept the defaults for queue_file and queue_depth. /etc/audisp/plugins.d/au-remote.conf By default the dispatcher is configured off, therefore remember to set active=yes to turn on the remote logging. /etc/audit/auditd.conf Once you are happy with the logging, turn off the local copy. For CentOS C7.3 and later machines use: local_events = no log_format = RAW --%< I have not tested this recently, it was last running (IIRC) on C6/7, so proceed with caution.

Even though I agree that they “taught the world how to copy”, at some point I dropped them, and wherever my word counts I recommend against Xerox. At some point they started making slight modifications to printer models thus making pretty much the same printers only with toners incompatible between models. Thus, each “model” was produced in smaller number, making aftermarket toner manufacturing unprofitable. That was only half of trouble, we were buying Xerox supplies anyway. But at some point they stopped making toners for printers as young as 6 years old if memory serves me. So, we had to throw away good working Xerox printers merely 6 years old, as you can not get toners for them. They, BTW, didn’t fix vulnerability in these older printers as well. Since that event my decision is: NO XEROX ANYTHING! For comparison: we had; still have HP 4050 that was getting a lot of use and beating it is 19 years old now, still works, you still can buy HP toner for that.

I haven't been following this thread closely, so may be off target. When pages are moved out of the working set they are either "clean" or "dirty". Clean pages have not been modified since they were originally moved into memory whereas dirty pages have been changed. A dirty page can become clean if it is written back to disk. Typically (though not always) this is a write to swap. Read only pages, such as code or data will always be clean, so can be dropped when required. When a hard fault occurs then pages have to be read from disk, somewhere. That somewhere could be swap, but can also be program images or files.

For EPEL and other EL repos you have to jump multiple Fedora releases to catch up. So in EL6 we were Fedora Linux 12. In EL7.0 we had to jump and rebuild from scratch a lot of Fedora Linux 18 and Fedora Linux 19 and then progressed up to about Fedora 24 as various parts got rebased and upgraded to 7.9. For EL8, we have to jump to Fedora Linux 28 and then each dot release rebase parts while keeping other parts back because rebasing is focused. [This means that if something needs glibc-2.32 you can't put it in EL8 without a lot of patching to make it work with whatever changed... but some other related components may be able to recompile fine.] Thus you need people who enjoy that kind of work to do this because EPEL is nearly all volunteer work. I had to work after hours or take vacation time to work on getting EPEL-8 out so that I could get focused effort on it.

Are you getting any mail? $ mail mail Subject: test test ^D $ If you get no message then logwatch isn't your issue. Next check your cron file, it ought to be in /etc/cron.daily/0logwatch Ensure that LOGWATCH_SCRIPT actually points to the code (typically /usr/sbin/logwatch) Check that the line for the following line: OPTIONS="--output mail" The actual invocation on my system is: $LOGWATCH_SCRIPT --range="between $day and yesterday" $OPTIONS As a final resort, edit 0logwatch and add the line "set -vx" just above the invocation. This will generate output which cron will attempt to send to root. Regards, Martin On 13/11/2020 12:03, Blaž Bogataj wrote: Hello I am trying to get logwatch working on CentOS 8.

Re: [CentOS] Laptop and NFS homedir
I've been playing with OwnCloud on a home network recently and it seems to be handling sync traffic well. A couple of points to make: 1) Be aware that the server and client repositories are different. You can do a lot with the web interface to the server, but you'll really want the client for ease of use. 2) Synchronising isn't instant. It can take a few minutes for 100+ MiB syncs, particularly since I was going W10 (clinet)->VM (server) ->host (client). Other than the above, it's basically set-and-forget. I can download photos onto the laptop, run GIMP on the C7 machine, and store the results on the C8 VM server quite happily.

There are some downsides though to be aware of: * HPLIP doesn't support all HP printers, and not as quickly as you might wish, so be prepared to find the nearest model for CUPS. * HP have sharp practice over toner cartridges. To be clear, software updates will invalidate full third party cartridges which end up on the skip. The phrase "sod the customer" comes to mind. On the plus side, quality is good.

Re: [CentOS] Default ACL inheritance question
Look at the acl(5) man page and you'll see that the ACCESS CHECK ALGORITH starts: IF the effective user ID of the process matches the user ID of the file object owner ... ELSE IF the effective user ID of the process matches the qualifier of any entry of type ACL_USER, THEN IF the matching ACL_USER entry and the ACL_MASK entry contain the requested permissions, access is granted, ELSE access is denied. ELSE ... The effective user ID is . This matches an ACL_USER entry (user:user-b:r--) so therefore consider the ACL_MASK. It is "---" so does NOT contain the requested permission, and therefore access is denied. Right, now we know why access is refused. Cast your eyes slightly further up the man page to OBJECT CREATION AND DEFAULT ACLS. Point 1 states that the object inherits the default ACL of the containing directory as its access ACL. So far so good, but point 2 states that the "file permission bits are modified so that they contain no permissions that are not contained in the permissions specified by the mode parameter". What I suspect is happening is that the mode parameter is set during file creation and so the mask is cleared to ensure that the creator's wish overrides the directory default. You need to either investigate the application (difficult, long winded), contact support (good luck), or find a way to live with it. Sudo is one solution, another is a script that does a setfacl -m m::rx logfile.

Re: [CentOS] CentOS 8 on USB disk
I'd be a bit careful with that one Joakim. If dd throws an error for any reason the sync will not run and your USB may be in a partially written state for some time. Since it is not mounted, there is no umount command to sync for you. If you pull the stick out shortly after the dd command was run you will have a partially written USB - nasty.

Having said that, with the current increase in interest in space activity the old Apollo 8 logo might give us some inspiration. See https://en.wikipedia.org/wiki/File:Apollo-8-patch.png for the original. My initial though is for the CentOS logo where the earth is and some sort of future at the Moon end. Perhaps a star? I'm a programmer not a "creative" so I'll allow artistic types to decide. If obscuring the CentOS logo with the lower band of the "8" is unacceptable, then it would be possible to keep the Earth and put the CentOS logo in place of the Moon. Not as strong a message, but still fun. The three astronauts' names cound be replaced with the word "CentOS", a slogan (please not "to infinity and beyond"), or simply blanked.

I have three USB disks, each of which is capable of holding half a dozen backups. Disk 1 has slots 11-19, disk 2 21-29 and disk 3 31-39.

Amanda (from base CentOS) -> USB removable disk -> firesafe. Backups on or by the computer might protect you from disk failures, but are useless in case of fire or theft.

Re: [CentOS] DNS bind - use of /etc/named directory
The '/etc/named.conf.rpmnew' file supplied is a bare minimum to "configure the ... server as a caching only nameserver (as a localhost DNS resolver only)". As soon as you start adding any structure to it things change, not just are added to. See '/usr/share/doc/bind-*/sample/etc/named.conf' for example. Probably the biggest "gotcha" is that as soon as you use _any_ views you MUST use views for _all_ zones. If you were to move the default '/etc/named.conf.rpmnew' to '/etc/named.conf' and add an 'include "/etc/named/*";', line as you suggest, you would be building problems for the future. Let's say you dropped in 'internal.conf' which had a simple 'view "internal" stanza - then your root hints, localhost, localhost IPV6 and reverse localhosts would disappear. Just what you wouldn't want at 00:51 ! What you can do safely is to include the zone definitions in a separate file (see '/etc/named.rfc1912.zones' for example) and include that file. Doing things this way means that your main configuration file can be written to either use views or not, and to just include your zone definitions in the appropriate place. See the sample file for an example. HTH, Martin On 04/12/18 00:51, John Horne wrote: > Hello, > > For many years we have modified the '/etc/named.conf' file to include local > settings.

Re: [CentOS] odd popups
No image found. This may be due to ABRT. Expand the details at the bottom of the pop-up and if the Vendor is "The ABRT Team", then the pop-up is benign. You can read problems you have encountered, but if a daemon or any other user hits a problem you do not have the authority to look at their processes. To further check this, go to Applications>System Tools>Automatic Bug Reporting Tool. You can look at the "My" tab, but looking at the "System" tab (for example) will trigger the pop-up. Enter the root password (if you know it) and you will see a list of System's problems.

If your failed disk is on (as an example) /dev/sdc, the command is: # dd if=/dev/sdc of=/home/dd-copy-of-sdc It will take a long time, and ensure that /home has enough space for the complete disk. Use kpartx(8) to make the disk visible and you can then mount the partitions. lvs(8) will tell you about any logical volumes and IIRC, lvchange allows you to activate them.

Once the firewall was off setting the multicast_querier seems to have done the trick.

[CentOS] Corosync on a home network
I've been trying to build a model cluster using three virtual machines on my home server. Each VM boots off its own dedicated partition (CentOS 7.3). One partition is designated to be the common /home partition for the VMs, (on the real machine it will mount as /cluster). I'm intending to run GFS2 on the shared partition, so I need to configure DLM and corosync. That's where I'm getting bogged down. The VMs and the real machine are bridged onto one ethernet. There is another ethernet in the main machine on a different network, but that is not used for clustering. The ethernet port is connected to a switch which in turn connects to a BT Home Hub 6. All four adresses are static, Network Manager is off, ssh works across the nodes without a password and ping gives sensible times. --%<--- # brctl show bridge name bridge id STP enabled interfaces br3 X no enp3s0 vnet0 vnet1 vnet2 virbr0 X yes virbr0-nic --%<--- When I start corosync each node starts up but does not see the others. For instance I see: --%<-- # corosync-quorumtool Quorum information -- Date: Sun Sep 10 12:56:56 2017 Quorum provider: corosync_votequorum Nodes:1 Node ID: 3 Ring ID: 3/28648 Quorate: No Votequorum information -- Expected votes: 4 Highest expected: 4 Total votes: 1 Quorum: 3 Activity blocked Flags: Membership information -- Nodeid Votes Name 3 1 192.168.1.52 (local) %<--- All four nodes are similar, but with different node IDs, IP addresses and Ring IDs. The documentation warns that not all routers will handle multicast datagrams correctly. I therefore attempted to force unicast communication by making the following changes from the distributed corosync.conf: transport: updu cluster_name: # crypto_cipher: none # crypto_hash: none # mcastaddr: 239.255.1.1 # mcastport: 5405 # ttl: 1 The following are unchanged: version: 2 secauth: off ringnumber: 0 bindnetaddr: 192.168.1.0 The nodelist is: -%< nodelist { node { ring0_addr: 192.168.1.2 nodeid: 1 } node { ring0_addr: 192.168.1.51 nodeid: 2 } node { ring0_addr: 192.168.1.52 nodeid: 3 } node { ring0_addr: 192.168.1.53 nodeid: 4 } } %<-- logging and quorum are as supplied.

Re: [CentOS] GPX files
Thanks for the suggestions. I'd seen gpsbabel, but simply converting the tracks doesn't appear to display them. Another user suggested a downloadable Google Earth, so I'll try that. Failing all else, I've used shell scripting in my day job for the last 18 years (and before that Digital's DCL for the previous 18 years). I'm just trying to avoid reinventing the wheel. Once again, thanks all for the suggestions.
