[CentOS] migrating from sendmail to postfix, centos 6 to centos 8

2020-06-03 Thread Chuck Campbell
I have an email server/aggregator which delivers locally for root, and 
all other emails in my domain. It sends outbound email to my isp 
(networksolutins) masquerading as my domain via smtp. This is with sendmail.


It does not receive email from the internet via smtp. I use fetchmail to 
get incoming mail from multiple email/isp's. I use procmail for local 
delivery and serve emails using dovecot/imap. These all work fine.


I am getting new hardware for this machine, and plan to setup centos 8, 
which uses postfix, not sendmail. I've been trying to provision a vm 
with the proper configuration, but cannot get any emails delivered to root.


Is there a pointer to a configuration guide that will help me do what I 
want? I have googled about 100 setups, none of which are what I'm trying 
to achieve. They all suggest using an alias for root to a normal user, 
but them that user gets all of the cron, fail2ban, etc emails, instead 
of delivering them to root on the local machine.


Thanks,

-chuck

Re: [CentOS] Bridge network for virt-manager

Hello. I desire to get bridge network working using virt-manager.



The easiest way to set up bridged networking on CentOS 7 is:

    virsh iface-bridge eth0 br0 --no-stp

This command will create a new bridge interface, br0.  The existing 
interface, eth0, will be added to the bridge, and its current IP 
configuration will be migrated to the new interface.

[CentOS] Logitech webcam for use with CentOS 7

2020-06-03 Thread H
I am thinking of buying a Logitech C920S Pro HD or C922 webcam for the 
necessary video conferencing.

Is anyone using that with Zoom or perhaps with Jitsi? Do I need drivers? Any 
issues?

Thank you.

You may want to have a look at elrepo and the kernel-ml package. Doing
this yourself can be painful.

[CentOS] How to rebuild the kernel

2020-06-03 Thread Harsh chopra
Hi everyone,
I am using Centos 7.8.2003 kernel 3.10
. I was trying to build and install the latest linux stable kernel i.e.
5.7, I successfully did the process but accidentally messed it up by
copying the .config file again in 5.7 kernel src,I tried to rebuild the 5.7
kernel but got make error as I was still on 5.7 kernel.

Then I changed to 3.10 and tried to rebuild 5.7 but was not successful.
I tried to reboot the system but this time I was in the maintenance mode.

So if anyone could suggest any help in recovering the 3.10 kernel.
