Re: [xcat-user] Using chrony instead of ntp?

2018-11-28 Thread GONG Jie
Hello Vinícius Ferrão,

Please make sure chronyd is installed on the node you intend to use it. And 
redo the xCAT ntp setup procedure on that node.

For the xCAT management node, do the following,
  1. Make sure chronyd is installed on xCAT management node.
  2. Run `makentp’

For xCAT compute nodes, do the following,
  1. Make sure chronyd is installed on xCAT compute nodes you intend to use 
chronyd
  2. Run `xdsh compute_nodes setupntp’, where compute_nodes is your node range.

Re: [xcat-user] [External] How to restrict xCAT's NFS shares?

2018-11-28 Thread Bin XA Xu
xCAT team are considering not to generate the default export entries for /tftproot and /install,  but you can follow up the documents to created it per your demand. (For example, some cases (service node,  statelite) requires NFS and you want to use xcat MN as its NFS server )
 
This will introduce some inconveniences.

Yes, you appear to be correct. I just, for testing, uninstalled all of xCAT. Then I manually removed the entries, and re-installed the xCAT RPMs. Lo and behold - it did in fact re-create the entries (but did not remove them when uninstalling xCAT).

I noticed that xCAT shares /tftpboot and /install as world-writeable. Is there a way to restrict these NFS shares to only the networks within the cluster, without making them globally available?
 
Specifically, xCAT creates this /etc/exports file:
 
/tftpboot *(rw,no_root_squash,sync,no_subtree_check)/install *(rw,no_root_squash,sync,no_subtree_check)
 
I would like it to instead create this:
 
/tftpboot  192.168.10.0/24(rw,no_root_squash,sync,no_subtree_check)
/tftpboot  192.168.11.0/24(rw,no_root_squash,sync,no_subtree_check)/install  192.168.10.0/24(rw,no_root_squash,sync,no_subtree_check)
/install  192.168.11.0/24(rw,no_root_squash,sync,no_subtree_check)
 
(where 192.168.10.0 and 192.168.11.0 are two networks defined in the network table)
 
Is that doable?

Hello Casandra,

Thanks for sharing the correct info. In a case of an already deployed xCAT on 
RHEL7, is it possible to change it back to chronyd instead of ntpd?

Which steps are needed?

Re: [xcat-user] [External] Re: Excluding a node from discovery?

2018-11-28 Thread Christian Caruthers
If you define the mac address and set the chain table so xCAT will not try to 
"do" anything with the node:

chdef {NODE} currstate=boot currchain=boot chain=boot

nodeset {NODE} boot

You probably don't need all of those chain table settings, but that should 
catch everything. This way, the DHCP server will not attempt to discover or 
install when a PXE request is received.

If mac address defined, DHCP server already knows this node. bmcdiscover will 
not send genesis kernel , but the node attribute will be replaced from discover 
packet if there are difference.

For the mtms-based discover, the bmcdiscover will send findme packet and 
looking for per-definied node with same mtm/serial. Yes, if it didn't find, 
that would cause bmcdiscover to think this node hasn't been discovered, the 
temp bmc discover will not be removed from xcat database.

The discover packet should contain same info as what defined for the storage 
node (CPU, disksize, mtm/serial, memory), i think you should just keep mac, 
mtm/serial for the storage node, it will not run into discovery process.

I am looking for a way to exclude one node from being discovered (MTMS-based 
discovery).

The background is that we have quite a few compute nodes, and one storage node. 
The storage node is managed separately, but is of course connected to the same 
networks as the compute nodes. If I blindly run bmcdiscover on the whole 
subnet, it will discover the storage node. The worst-case scenario is that I 
accidentally reformat it and lose data.

So I am looking for a way to keep this node from ever even being discovered in 
the first place. Any ideas?

I noticed that xCAT shares /tftpboot and /install as world-writeable. Is there 
a way to restrict these NFS shares to only the networks within the cluster, 
without making them globally available?

Specifically, xCAT creates this /etc/exports file:

/tftpboot *(rw,no_root_squash,sync,no_subtree_check)
/install *(rw,no_root_squash,sync,no_subtree_check)

I would like it to instead create this:

/tftpboot 
192.168.10.0/24(rw,no_root_squash,sync,no_subtree_check)
/tftpboot 
192.168.11.0/24(rw,no_root_squash,sync,no_subtree_check)
/install 
192.168.10.0/24(rw,no_root_squash,sync,no_subtree_check)
/install 
192.168.11.0/24(rw,no_root_squash,sync,no_subtree_check)

(where 192.168.10.0 and 192.168.11.0 are two networks defined in the network 
table)

Is that doable?

Thanks!

Casandra,

Thank you very much - I didn't know that. Just tried it on RHEL 7, and
makentp indeed detects that chrony is installed instead of ntp, and then
proceeds to configure chronyd.

Awesome!

Re: [xcat-user] Excluding a node from discovery?

2018-11-28 Thread Casandra H Qiu

You may need to remove mtms/serial number from storage node definition.
Also,  you should remove mac address from storage node definition,
"makedhcp -d storagenode "   to remove from DHCP lease file


Thanks,

Subject:[xcat-user] Excluding a node from discovery?



I am looking for a way to exclude one node from being discovered
(MTMS-based discovery).

The background is that we have quite a few compute nodes, and one storage
node. The storage node is managed separately, but is of course connected to
the same networks as the compute nodes. If I blindly run bmcdiscover on the
whole subnet, it will discover the storage node. The worst-case scenario is
that I accidentally reformat it and lose data.

So I am looking for a way to keep this node from ever even being discovered
in the first place. Any ideas?

Thanks!

Re: [xcat-user] [External] Encrypted passwords in passwd table

2018-11-28 Thread Jarrod Johnson
It can only work for the root passwd.  You can take the value in /etc/shadow 
and copy it in verbatim instead of the plain value.  Root password can be 
non-recoverably encrypted (you only need to tell the nodes how to prove someone 
knows a password, not actually know the password itself).  For things like 
IPMI, the password must be known by xCAT, and for such passwords there's no 
encryption available.

For IPMI, if wanting to have an encrypted storage of the password, you can skip 
xCAT configuration and use confluent which does have support for recoverable 
encryption, though the default behavior has decryption key in the clear, and if 
the user wants to protect the decryption key, the functionality exists but is 
not documented (it requires the user either type a password or chain it to a 
key of their choosing).  There has been plans to be able to bind copies of the 
crypto keys to system TPMs, but so far no one has actually asked for that.

Subject: [External] [xcat-user] Encrypted passwords in passwd table

Looking to set up encrypted passwords, and the only documentation I see it on 
the old SF site:

https://sourceforge.net/p/xcat/wiki/Encrypted_root_password_in_passwd.tab/

Is there any newer documentation? I didn't see it on the readthedocs site. 
Also, does this only work for the root password, or can it also be used for 
IPMI?
