A reboot solved it, powering the device off/on made no difference, as did replugging the cable. Afterwards, I recalled that I had run a much belated yum update 2 or 3 days ago and had failed/forgotten to reboot. Probably some necessary item had gotten wedged somehow because of that. (seen it before, but not with a USB device.) Thanks for the reply, though.

The source has it here: https://github.com/rpm-software-management/rpm/blob/master/rpmpopt.in#L198 (this is how rpm knows to run rpmkeys for that switch) It appears that it was introduced in 2010, and the functionality was removed from rpm in this commit: https://github.com/rpm-software-management/rpm/commit/3cbda9c03f1feb872397f4afe75988b20746f403 and the man page was updated in this commit: https://github.com/rpm-software-management/rpm/commit/c6d98322f1d30ca8028efb63bfde24b554abfda1 -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Custom ISO
Thanks for hint. I have changed to this: genisoimage \ -v \ -J -R \ -V "$NAME" \ -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 \ -boot-info-table -eltorito-alt-boot -b images/efiboot.img -no-emul-boot -boot-load-size 18755 \ -o $DESTINATION_FILE . it now creates the ISO and is EFI bootable. However - I have a different issue arise. In normal install or EFI install (both) it hangs at "Starting dracut initqueue hook..." Only thing I am changing is the add the boot options for my kickstart file. So then I tried select the "standard" "Install CentOS 7" and it does the same thing, hangs at "Starting dracut". Any thoughts on that ? I am testing with virt-manager. Thanks, Jerry ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

[CentOS] network disconnection after several hours
Hello, Here is the context during the problem occurs : We have a new machine running on centos 8.From this machine, we restore a postgresql dump on an other machine runnning on centos 7.After several hoursof running, restore fails due to a disconnection (no route to host).But, if we disable the firewall on centos 8, restore succeed. Before having this new centos 8 machine, we had a centos 7 machine and all worked fine with firewall activated. Has anyboby an ideas, clues or something else?

[CentOS] Odd permissions
I've posted a couple times in the last month, that for some reason, since I rebuilt to CentOS 7 from 6 (same home directory, another partition, of course), when I log out, it restarts with me logged in, and only the second time I log out does it actually log me out. Still debugging that. I have logged in as root, and don't have the problem, so I'm assuming that it's something incompatible, or somehow mis-set in ~/.. Looking in ~/.cache, I found something weird: ~/.cache/gnome-control-center, which had permissions of d-w-rwxr-T Say *what*? Anyone got a clue as to why?

Are you really sure it happens because of the firewall? Anything in the logs indicating it happens because firewalld fiddles with something? I gues by firewall you mean firewalld. Usually such situations can come from NetworkManager with its default configuration. If, for some reason, an ethernet device looses link for a short time, NetworkManager is eager to bring down the interface and the result is the nice "no route to host" situation. To prevent NM from "helping" you in this situation, you have to install the server subpackage from NM - or get rid of it :-) Regards, Simon ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
