Then that looks like the command 'getcredentials.awk ssh_dsa_hostkey' does not work when do the OS deployment. Does executing command 'updatenode <node> -P remoteshell' also failed with multiple retries?
Could you show me the output of 'lsxcatd -a' and the OS of your compute node?
Thanks
Best Regards

Then everything looks good.
If you are using xCAT 2.11, please enable the debug mode
# chdef -t site clustersite xcatdebugmode=1
And run 'updatenode <node> -P remoteshell', then show me the log in the /var/log/xcat/cluster.log from your MN.
Thanks

Could you try following steps on your compute node?
1. Enable mini server
/xcatpost/allowcred.awk &
2.Try to get rsa hostkey
USEOPENSSLFORXCAT=yes XCATSERVER=<MNIP>:3001 /xcatpost/getcredentials.awk ssh_rsa_hostkey
The output should like:

Refer to the following part of code in credentials.pm. You can get more messages in the /var/log/messages on you xCAT MN. xCAT is trying to send the file /etc/xcat/hostkeys/ssh_host_dsa_key to compute node. This file is generated during install xCAT. Could verify this file is existed?

Hallo,
i am very pleased with xCAT in general and only have a small problem, which i could work around, but id rather it worked as intended.
I have a bunch of diskless nodes, which i manage and everything is working as i wish apart from the host key transfer. the xcat.log on the nodes shows the postscript "remoteshell" takes about 20 min to execute
and if i have a look at the log on the managing node i get this

Jan 25 14:51:28 xcat xcat[19112]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02
which looks like the node cannot access the keys and after the 10 tries it generates a new key.
This is very unfortunate and i am out of guesses, where this problem originates from.
Could you give me a hint!?
Regards
Sebastian Hollizeck
