Dear Simon, every second IP-address is unwanted. We restarted? eno4: nmcli con down eno4; nmcli con up eno4 and the second address vanishes. Then after a few ours, the second ip address reappears. This is the config-file of eno2: # cat ifcfg-eno2 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes

Hi, Can you show as the config of eno4? And can you diff the config of eno1 and eno4. Looks like there is a difference somewhere. Regards, Simon > > > This server is equipped with four nics

Dear Mark, thanks for the additional hints.

What about eno2, you also have two IP addresses there and even in the same subnet, is this wanted or not? Can the second address of eno2 be found in the ifcfg file? Both eno2 and eno4 have "scope global secondary dynamic"

I think it does so and

Have you tried to use NetworkManager ? After all ,anything network related should be done by it. [root at system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy ? Connection 'dummy0' (9fdd74fa-c143-4991-9bac-0e542704ac89) successfully added. [root at system ~]# reboot Shared connection to glustera closed.

Anyone have any ideas? It's rather annoying that I can't get these to persist across reboots without using some kind of helper script.

Hello all, hoping someone can help me out here. I cannot get dummy interfaces on a new Cent8 build to persist across reboots. On Cent7 - this is the process I use: Create Dummies: # cat /etc/modules-load.d/dummy.conf dummy # cat /etc/modprobe.d/dummyopts.conf options dummy numdummies=4 # ip link add dummy0 type dummy ## - repeating a/ ascending dummyN adapters for as many needed # service

Hi all, I have done some tests for the new attributes "check" and "type", could you please help to have a check? And I have some questions about the patch, please help to have a look, Thank you!

No. Network Manager is always disabled on our builds since at least Cent5 days. The network stack has always been able to be managed properly without relying on Network Manager. Is that now an absolute requirement? It never has been prior.

Requirement is a very strong word , but you should consider using it and here is a short demo why: - By default, RHEL uses NetworkManager to configure and manage network connections, and the /usr/sbin/ifup and /usr/sbin/ifdown scripts use NetworkManager to process ifcfg files in the /etc/sysconfig/network-scripts/ directory. [root at system ~]# ls -l /usr/sbin/ifup lrwxrwxrwx. 1 root root 22 21

Dear Samba-List, i'm new to the list and new to samba. Right now I'm trying setup a samba ADDC serving around 50 Windows 10 clients and a couple of linux clients. My ADDC Host has two NICs, eth0 should be connected to the wan - network, eth1 should be connect to a 10.* network, serving the windows and linux clients. The ADDC is up and running, serving only the 10.* network. I

Got a problem: a user's workstation froze. He wound up rebooting, without calling me in first, so I dunno. But, and this is a show-stopper, when it came up, it came up with the firmware MAC, not the spoofed one. In /etc/sysconfig/network-scripts/ifcg-eth0, I've got the spoofed MAC address, and a UUID. In the grub.conf, I've got net.ifnames=0 biosdevname=0. But when I logged onto his

Hello, I have configured an samba AD DC for use with some windows and linux machines. The linux machines use samba for user auth and also as kerberos kdc for nfs mounts. This works fine so far but after a while the user can not access the nfs shares anymore. I tried to analyze the problem and finally found, that the obtaining a ticket for nfs service failes in this case because of a wrong

I got it. Thanks. The share is working. Only problem, I need some files to be only readable for the end user (templates) the problem is windows doesn't for some reason allow me to change the rights. I am using dutch windows so the error is dutch but translated it say. Can't connect/find active directory to verify or open claimtypes. Philip "Rowland penny via samba" <samba at
