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 14:46:48 xcat xcat[19066]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:47:06 xcat xcat[19070]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:47:17 xcat xcat[19073]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:47:35 xcat xcat[19076]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:47:52 xcat xcat[19078]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:48:08 xcat xcat[19081]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:48:19 xcat xcat[19083]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:48:36 xcat xcat[19086]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:48:47 xcat xcat[19088]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:49:01 xcat xcat[19091]: xCAT: Allowing getcredentials ssh_dsa_hostkey from cpn02 Jan 25 14:49:17 xcat xcat[19093]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:49:33 xcat xcat[19096]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:49:45 xcat xcat[19098]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:49:55 xcat xcat[19100]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:50:09 xcat xcat[19102]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:50:28 xcat xcat[19104]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:50:42 xcat xcat[19106]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:50:57 xcat xcat[19108]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 Jan 25 14:51:14 xcat xcat[19110]: xCAT: Allowing getcredentials ssh_rsa_hostkey from cpn02 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!?
