Re: Cannot get system to boot older kernel w/ grubby

No, its a machine at a location which is in shutdown and there is no employee access, only remote access. So physical access to the machine is not a possibility at this time, unfortunately, that would make my life easy.

pxeboot install

I'm trying to add centos 8 to my pxeboot server and having zero success. i have rsync'd the centos/8/* files to my server's path /remoteinstall/boot/x64/images/centos8 (as I have done in the past with centos7 and centos6) I copied my pxeboot entry for centos 7 (which works fine) LABEL xc7 kernel ima...

Re: Any plans for WSL distro?

that's very disappointing. I enjoyed running centos under wsl.

Sad to see RedHat and Centos are slowly falling behind the times.

Mirroring outbound https traffic w/ iptables

I have a couple of IOT devices (thermostats) which talk to the mothership with https . They send a packet of data containing a querystring w/ parameters containing such items as current temperature, which I can view on my smartphone via their app. I'd like to be able to 'mirror' those packets to my ...

Re: nfsv4 idmapping between domains

All the clients are identical. They are pretty much a stock CentOS 7 rollout with a few minor configuration changes to integrate it into the network (e.g. join it to ad, change /etc/auto.master to set the global common mount point to something other than /net, etc.) I am hesitant to start fiddling a...

Re: nfsv4 idmapping between domains

What happens when you disable version 4 on old.mydomain.com? Hundreds of clients start puking with "protocol not supported" errors when they attempt to automount filesystems on old.mydomain.com. The clients do not seem to negotiate down in nfs versions. The NFS version is negotiatable between serve...
