Have you changed the postfix config at all? Because usually it is happy to deliver local mail for local users. The aliases file should have something like root: chuck where 'chuck' is the local user; that will put the message in /var/mail/chuck. There's a postfix config variable called 'local_recipient_maps' that determines what is a local recipient - but the default uses, amongst other things, the standard unix passwd file. P.

migrating from sendmail to postfix, centos 6 to centos 8
by Chuck Campbell 04 Jun '20

04 Jun '20

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 --

How to rebuild the kernel
by Harsh chopra 03 Jun '20

03 Jun '20

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.

Hi everyone, My PC don't have an integrated WLAN card, so I bought an USB WIFI device which use the MediaTek MT7601U chip(image 'dongle.jpg'). ------------------------------------------------------------------------------------------------------ My PC specification- OS = CentOS 7.8.2003. Processor = AMD Ryzen 5 1600. Mother-Board = GA-Gigabyte A320M-S2H ------------------------------------------------------------------------------------------------------- The lsusb lists devices- It is in the attachments below (ls_usb) Under /lib/modules/3.10.0-1127.el7.x86_64/kernel/driver/net/wireless/ - It is in the attachments below (wireless_list) Under /lib/modules/3.10.0-1127.el7.x86_64/kernel/driver/net/wireless/ralink/rt2x00 - It is in the attachments below (ralink_list) lsmod list - It is in the attachments below (ls_mod) ---------------------------------------------------------------------------------------------------------- I found the github page for installing MT7601U Linux driver "https://github.com/imZack/mt7601" I am having trouble in building the driver as the installation process requires Synology toolchain <http://sourceforge.net/projects/dsgpl/files/DSM%205.1%20Tool%20Chains/> and kernel source <http://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/5…> But I don't know which toolchain and Kernel source to install also I had to manually load the modules rt2800usb.So if anyone have any suggestion please let me know.

How can I define a local use with "@" in the name useradd "bob@myname" gives error. I "need" to have the @ sign in the name -is that possible. Silly reason - the system I am trying to send emails to the linux server has a bug. I'm trying to get around it. Thanks, Jerry

looking for ideas about how to create a constant data stream
by hw＠gc-24.de 30 May '20

30 May '20

Hi, I'm looking for a good way to create a constant data stream that will occupy a bandwidth of about 2--5Mbit/sec between two remote hosts over the internet. I have full access to the hosts involved. My first attempt to use scp to copy data from /dev/null on host A to /dev/null on host B, but scp says '/dev/null: not a regular file'. If something like that would work, I would be able to limit the bandwidth of this transfer in the router(s) involved so that it won't occupy all the bandwidth. Of course, it would be better if I could limit the bandwidth on the sending side rather than dropping packages. I could probably write some program to do that, but since I have never programmed such a kind of network application, it would be rather time consuming. Maybe there's already a kind of tool around that can do this. I need this to work around whatever settings my ISP has made 3 days ago that block my VPN connection so that I effectively can't reasonably work anymore. I do know what the problem with the connection is and that occupying some bandwidth would unblock the VPN; only there doesn't seem to be anything else I could about it.
