Re: [xcat-user] Starting xcatd Error in GnuTLS initialization: Failed to acquire random data.
hi Pharthiphan Asokan, the error message "SSLEAY_RAND_BYTES:PRNG not seeded" is thrown out by openssl due to lack of random source and seed file on the node. Please check the openssl version on your management node, and check the existence of random devices by `ls -l /dev/*random` and seed file by `stat ~/.rnd` more details: https://www.openssl.org/docs/faq.html#USER1 --YANG Song (杨嵩)IBM China System Technology LaboratoryTel: 86-10-82452903Email: yang...@cn.ibm.comAddress: Building 28, ZhongGuanCun Software Park,No.8, Dong Bei Wang West Road, Haidian District Beijing 100193, PRC北京市海淀区东北旺西路8号中关村软件园28号楼邮编: 100193 - Original message -From: Pharthiphan Asokan To: xCAT Users Mailing list Cc:Subject: [xcat-user] Starting xcatd Error in GnuTLS initialization: Failed to acquire random data.Date: Thu, Jun 28, 2018 1:08 PM Hi, I start getting that following error while chaning the rootdir for diskless client. chdef -t osimage -o centos7.4-netboot rootimgdir=/install/netboot/centos7.4/x86_64/centos7.4-netboot Unable to open socket connection to xcatd daemon on localhost:3001.

Re: [xcat-user] resolv.conf multiple search domains
Hi Jeff, You can also customize /etc/resolv.conf. When a node boots up in statelite mode, it will by default copy all of its tmpfs files from the .default directory of the root image, for example /install/netboot/rhels7.3/x86_64/compute/rootimg/.default, so there is not required to set up a litetree table. If you decide that you want some of the files pulled from different locations that are different per node, you can use this table. The litetree table controls where the initial content of the files in the litefile table come from, and the long term content of the ro files.

After liteimg, the .defaults/etc/resolv.conf file contains just the dummy line. And on boot, I end up with a resolv.conf that looks like:search nameserver nameserver nameserver nameserver That is, the same domain is duplicated on the search line. The nameservers themselves are correct, though.I tried editing the .defaults/etc/resolv.conf file, but it had no effect.Obviously I am unclear on how that resolv.conf file is being generated, and any pointers that anyone can provide will be gratefully followed up.Jeff Berry, MRC CBU--Check out the vibrant tech community on one of the world's mostengaging tech sites, Slashdot.org! http://sdm.link/slashdot___xCAT-user mailing listxCAT-user@lists.sourceforge.nethttps://lists.sourceforge.net/lists/listinfo/xcat-user -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot___ xCAT-user mailing list xCAT-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/xcat-user
