weird cluster error on sync

[Mark N]

I am getting a weird error.
When I execute
wsrep_sst_xtrabackup --role 'joiner' --address '172.19.56.89' --auth X:X' --datadir '/data/mysql_cluster_2/' --defaults-file '/etc/mysql/
my_cluster.cnf' --parent '28005'  ''
manually it says it is in a ready state. I thought apparmor might be an issue, but turned it off and also ran it as the mysql user.
For some reason, it still aborts.
I also run innobackupex  on the donor using the account specified and it works.

It seems it it is failing to setup a listening port on the node being added before it even tries to transfer stuff.

Hi Mark,

Do you have the socat utility installed?
