THX Nathan! I should be able to test both on new HW which require the HMAC-SHA256 soon and report back. I still do not understand why my output is different than yours, but this is just my lack of knowledge around ipmitool most likely. I will try on the new system and see.

Regarding IPMI.pm – Any reason the patch below was not merged? Can you consider merging it now to allow support? We have not merged the patch yet for two reasons: - We did not know how to test this change and verify that HMAC-SHA256 was getting used successfully. - We don't have access to any x86 hardware that supports HMAC-SHA256, so we were unable to test the change. If others in the community could update https://github.com/xcat2/xcat-core/pull/6391<https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fxcat2%2Fxcat-core%2Fpull%2F6391&data=05%7C01%7Cgberman%40lenovo.com%7C1a124a8017974cb4fefc08db1a5e0403%7C5c7d0b28bdf8410caa934df372b16203%7C0%7C0%7C638132763334353526%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=l8RtwQNkkg4KS7xw1W3a1PmXfzpKOh%2FXusjMslc7Vn4%3D&reserved=0> with a test description that can be used to verify the change and some results of that test from one or more x86 platforms that support HMAC-SHA256, it would give us more confidence in merging the PR. > 2. Ipmitool-xcat – We are using the latest package - ipmitool-xcat-1.8.18-4.x86_64 – but it still do not have Cipher Suite 17, although ipmitool-1.8.18 should have it (*).

HMAC-SHA1 may be still secure, but SHA1 in any context *looks* bad even if it isn't. github.com That change to IPMI.pm might alleviate. Double check if ipmitool with -C 17 will work, and if that will work, you may need IPMI.pm to change to support SHA256 in the hmac. ________________________________ From: Mark Gurevich via xCAT-user <xca...@li...<mailto:xca...@li...>> Sent: Thursday, February 23, 2023 1:35 PM To: xCAT Users Mailing list <xca...@li...<mailto:xca...@li...>> Cc: Mark Gurevich <gur...@us...<mailto:gur...@us...>> Subject: [External] Re: [xcat-user] ipmitool -I open vs lanplus vs lan xCAT uses raw ipmi commands to do ipmi communication.

Use "chdef -t site clustersite xcatdebugmode=0" to turn debug off. -----Original Message----- From: Michael Green <mis...@gm...<mailto:mis...@gm...>> Sent: Thursday, February 23, 2023 1:08 PM To: xCAT Users Mailing list <xca...@li...<mailto:xca...@li...>> Subject: [EXTERNAL] [xcat-user] ipmitool -I open vs lanplus vs lan Hello collective wisdom, What IPMI interface does xcat use? Is it lan or lanplus or open? (As in ipmitool -I ) Is it configurable? I have a bunch of new Dell servers in the lab that don't seem to communicate over lan or lanplus interface, only open and I have trouble provisioning them through xcat. I suspect it's because of lanplus not supported/missing from these servers. -- Regards, Michael _______________________________________________ xCAT-user mailing list xCA...@li...<mailto:xCA...@li...> https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Fxcat-user&data=05%7C01%7Cjjohnson2%40lenovo.com%7Cb9b6b5f64d5e47f91cf908db15cce89f%7C5c7d0b28bdf8410caa934df372b16203%7C0%7C0%7C638127742055309654%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=%2BHmEMMvgmId52mKnS1F40GTNMtmzDWrZZ9a18N9s1r4%3D&reserved=0<https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Fxcat-user&data=05%7C01%7Cgberman%40lenovo.com%7C1a124a8017974cb4fefc08db1a5e0403%7C5c7d0b28bdf8410caa934df372b16203%7C0%7C0%7C638132763334353526%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=SFPSExmofbkPzlaiHQT7EUyUnOKyT7NJkXblmo12bt4%3D&reserved=0> _______________________________________________ xCAT-user mailing list xCA...@li...<mailto:xCA...@li...> https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Fxcat-user&data=05%7C01%7Cjjohnson2%40lenovo.com%7Cb9b6b5f64d5e47f91cf908db15cce89f%7C5c7d0b28bdf8410caa934df372b16203%7C0%7C0%7C638127742055309654%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=%2BHmEMMvgmId52mKnS1F40GTNMtmzDWrZZ9a18N9s1r4%3D&reserved=0<https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Fxcat-user&data=05%7C01%7Cgberman%40lenovo.com%7C1a124a8017974cb4fefc08db1a5e0403%7C5c7d0b28bdf8410caa934df372b16203%7C0%7C0%7C638132763334509769%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=UJCFMBqHpVBi1o%2Fv1FnMRHMLUY4%2BJrGniKyefpuoRXA%3D&reserved=0> |
