xCAT team is trying to create this issue.
Could you run the following command to enable the xcatdebugmode. Then do the os deployment and then to see what you can get from the syslog.
# chdef -t site clustersite xcatdebugmode=1
# service xcatd restart
Thanks
Best Regards

Hi,
is there any way i can make the remoteshell script work on boot? it really is bugging me, as the timeloss is substantial and the backlog of correcting ssh key later is also a lot of work.
System CentOS7.1
xcat Version 2.10 (git commit 79c7f6949c09e0b49875f10ede4b75b18ad4a0e7, built Fri Jul 24 05:27:07 EDT 2015)
Regards
Sebastian

It does seem like updatenode works if i use it later. here is a part of the STDOUT

Subject: Re: [xcat-user] getcredentials not working
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

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

/xcatpost/allowcred.awk &
2.Try to get rsa hostkey

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?
} elsif ($parm =~ /ssh_dsa_hostkey/) {
`logger -t xcat -p local4.info "credentials: sending $parm"` ;
if (-r "/etc/xcat/hostkeys/$client/ssh_host_dsa_key") {
$tfilename="/etc/xcat/hostkeys/$client/ssh_host_dsa_key";
} elsif (-r "/etc/xcat/hostkeys/ssh_host_dsa_key") {
$tfilename="/etc/xcat/hostkeys/ssh_host_dsa_key";
} else {
push @{$rsp->{'error'}},"Unable to read private DSA key from /etc/xcat/hostkeys";
`logger -t xcat -p local4.info "credentials: Unable to read private DSA key"` ;
next;
}
} elsif ($parm =~ /ssh_rsa_hostkey/) {
`logger -t xcat -p local4.info "credentials: sending $parm"` ;
if (-r "/etc/xcat/hostkeys/$client/ssh_host_rsa_key") {
$tfilename="/etc/xcat/hostkeys/$client/ssh_host_rsa_key";
} elsif (-r "/etc/xcat/hostkeys/ssh_host_rsa_key") {
$tfilename="/etc/xcat/hostkeys/ssh_host_rsa_key";
} else {
push @{$rsp->{'error'}},"Unable to read private RSA key from /etc/xcat/hostkeys";
`logger -t xcat -p local4.info "credentials: Unable to read private RSA key"` ;
next;
}
}
Thanks

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!?

Sebastian Hollizeck
