Hi Baris, Thanks for your reply. I’ve set OS to iDrac Pass-through to disabled and indeed the idrac interface has disappeared:
[root@penguin1 ~]# ifconfig idrac idrac: error fetching interface information: Device not found Have I understood correctly that this cripples the Service Module? That may be a downside… Kind regards, Onno Van: "Kayaturk, Baris" <[email protected]> Datum: woensdag 9 juni 2021 om 14:46 Aan: Onno Zweers <[email protected]>, "[email protected]" <[email protected]> Onderwerp: RE: [Linux-PowerEdge] How to kill idrac addresses fde1:53ba:e9a0:de11:* ? Hi, Can you try to disable OS to iDRAC Pass-Through ? In iDRAC Gui go to iDRAC Settings >>> Connectivity >>> OS to iDRAC Pass-through Give a try by switching state to disabled Regards. -----Original Message----- From: Linux-PowerEdge <[email protected]> On Behalf Of Onno Zweers Sent: Wednesday, 9 June, 2021 2:36 PM To: [email protected] Subject: [Linux-PowerEdge] How to kill idrac addresses fde1:53ba:e9a0:de11:* ? Hi everyone, With our new iDrac9 poweredges we notice that Centos 8 lists a specific IPv6 address for the iDrac. [root@penguin1 ~]# ifconfig idrac idrac: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 169.254.0.2 netmask 255.255.255.0 broadcast 169.254.0.255 inet6 fde1:53ba:e9a0:de11:3648:edff:fee7:5fcb prefixlen 64 scopeid 0x0<global> ether 34:48:ed:e7:5f:cb txqueuelen 1000 (Ethernet) RX packets 717841 bytes 52346458 (49.9 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 940803 bytes 77477775 (73.8 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 As the forth segment is “de11”, I assume it’s a Dell specific thing. The problem is that we have an application that gets confused by this and thinks it can use this address for normal traffic (as it is not private IP space). I’ve been trying to turn the address off, but have not been very successful. In the iDrac web interface I can’t see this address anywhere, and the IPv6 setting for iDrac is disabled. In the OS, I can remove the IPv6 address like this: nmcli dev mod idrac ipv6.method ignore ; nmcli device reapply idrac But after a few minutes it returns. Does anyone know where this address comes from, and how to turn it off reliably?
