You might also be able to use package metadata to determine what language it is written in, both by the dependencies as well as the file lists.

[CentOS] iptables routing question when using multiple IP addresses
I've been searching around for a couple of days, and I just can't seem to find the answer I'm looking for. I have a 6.x box that I use as my gateway firewall. It has three NICs; 1 external, 1 internal, 1 for a guest network. I have various inbound traffic routed to separate internal machines based on the application (ie. http, smtp, ftp, etc). All works well, but I'd like to add a second IP address to the external NIC and then route a second https stream to a different internal machine. So https traffic on one IP address goes to one internal machine and https traffic on a second IP address goes to a different internal machine. Seems like it should be an everyday configuration, but I can't find any clear examples on how to do it. Could someone please point me in the right direction? Thanks, Ken Gramm ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

EL6 would have installed because EFI support at that point was mainly a "eh oh yeah we need to cover that?" type thing. EL7 should be clearer on this but it might have gone the other way. Can you try to see if Fedora 27 has the same problem? If it has then this is a problem that upstream needs to fix on EL releases. If it isn't then I would lean more towards the motherboard/bios combo saying something which says "my legacy support is iffy.. use EFI". After that it is usually what is the motherboard/bios level and is it updated type fixes then. >> Thank you for your patience on this. > > I didn't realize you were the culprit, so that's OK. ;-) > Well I am not the culprit.. it is just most of my ideas have been completely useless. > -- > Yves Bellefeuille > > > > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos -- Stephen J Smoogen. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

You might want to try a "yum check-update" manually (maybe only against the epel repo). If you get an error try a "yum clean all" and then try the "... check-update" again. I didn't have a problem just now with the epel repo, but then again always start my checks with a "clean all". Of course this isn't a CentOS repo, so if you continue to have problems a report would need to be made with epel/fedora. As a note/side question ... I've never understood why this script (which I never leave installed) is in "cron.hourly". I would think that "cron.daily" would be a sufficient frequency. This appears to be a centos "touched" script so can't tell if upstream puts it in hourly or centos does. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

To really get rid of it use a tool that wipes GPT headers, or a full wipe of the drive. gdisk has eXpert mode that has an option (z) to wipe GPT headers. https://en.wikipedia.org/wiki/GUID_Partition_Table#/media/File:GUID_Partition_Table_Scheme.svg ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Install CentOS 7 on MBR hard disk
So is the end goal to have dual boot? You want to preserve the existing Cent OS installation on this drive and also install Cent OS 7? The biggest problem is the installer is really not very smart when it comes to this use case. It's friendly for Windows and macOS dual boot, but fairly well faceplants with dual boot Linux. So invariably you have manual surgery to do pre and post install, or suffer. Run 'efibootmgr' by itself, if you get boot entries the system is definitely UEFI booted. If you get an error, it's legacy/faux-BIOS booted. Certainly legacy boot is the easiest work around, but it can have an effect on various things including drive and video modes that might be different than UEFI booting. e.g. one of my older systems when booting legacy brings up the SSD in IDE mode not SATA, and the system is slower. And it can only use discrete GPU, the integrated GPU is unavailable. So I advise testing before committing to legacy mode. Also, rare, but not all UEFI systems come with a Compatiblity Support Module (fake BIOS), in which case you're stuck.

We have been trying to get the 503 error rate down in the last six months and thought we had licked it with recent changes. We had moved down the error rate to 80,000 bad requests per day out of 13.5 million total ones which actually is a creep up from what we had last month. Most of the requests every day happen in the time frame of XX:00 -> XX:15 of every hour. Every proxy seems to give about 100 per day but 2 proxies seem to have had docker problems and have been each contributing 32,000 to 38,000 503's. We did find an error in the docker restart script which hopefully will drop this further. We are still evaluating why just those 2 proxies have so many more and will let you know what is found.
