While what I have shown seems to work fine, for a better experience, it is also a good idea to correct the SELinux fcontext labels for the new base directory, /rhome, on the server machine. This guide should help: www.unixmen.com/selinux-and-non-default-home-directory-locations/
i have been watching your videos for the past couple of days and they are just great especially that i am preparing for rhcsa , i know its been a while since you made this video i hope you plan to make more quality videos like this ,can you please make a video on how to setup an update server that acts as a single update point for all the servers on the network rather than updating each server seperately , i searched all over the internet and read many books but no luck , since i am coming from a microsoft background the concept of an update server in microsoft enviroment is nothing new , but in linux it seems something else . thank you again for the top quality videos your way of explaining things is far and beyond of what we are used to and keep up the good work ,you deserve the title of instructor of the year .
No, that was not done in this video. However, you are making a good point in general as sharing directories with NFS under the regular /home would likely not work without tweaking selinux a bit. The reason the demo still worked was because of the nonstandard rhome basedir used in the video. Thanks for sharing that point
Thank you. I am looking into the topic and may produce a short video when my schedule permits. It would likely consist of using the IdM/FreeIPA services to set up a Directory Server and add directory users. Then we would need to configure the individual machines (using Ansible) to consult the directory server and automount the home directory with autofs.
Indirect autofs mount allows us to use “map key substitution” to dynamically mount an export if the mount point dir name matches with the remote file system dir name. I demo this by adding a new user, jchan, which gets a new home directory created on the nfs server machine and we can mount it on the other machine without having to add a configuration line for autofs.
The showmount command does not work with NFSv4 servers which is what was used in the video. NFSv4 is the default on RHEL9. You need to mount the path to the shared export by naming it directly. To enable the NFSv3 protocol you need to modify the config files and open more firewall ports for RPC. Hope that helps.
@@rakeshgowdav2467I am not sure what you mean by “console” but if you are referring to the exam console environment, red hat has a TH-cam video called “inside a red hat certification” that shows exactly what the environment looks like. Hope that helps.
As long as the objectives on the exam are covered, it should score well. Using chpasswd is certainly one way to manage passwords so it is probably fine. The only issue I see with this method is that if it is run in an interactive shell, the password will be stored in plain text in the command history file.

Such a good video. I failed the first attempt mostly because I couldn’t get autofs working. Thanks for sharing.
Hey, what were the hardest questions in your exam if you remember still.. Ill do mine today
Thanks. I appreciate it
Did you disable selinux nfs_home_dir?
No, that was not done in this video. However, you are making a good point in general as sharing directories with NFS under the regular /home would likely not work without tweaking selinux a bit. The reason the demo still worked was because of the nonstandard rhome basedir used in the video. Thanks for sharing that point
really useful.
Could You share LDAP Server installation and configuration cause it still very useful in real job.

why using indirect method ? why not using direct method sir?
Indirect autofs mount allows us to use “map key substitution” to dynamically mount an export if the mount point dir name matches with the remote file system dir name.

Showmount -e hostname getting
Client_create error:RPC unknown host
For showmount -e IP address getting exports
Does anyone know the solution for this

@@beanologi Thanks
Could you make one video about console in the exam

doesn't work !
do you see an issue with echo betty:redhat | sudo chpasswd on the exam??
