smartos vmunbundle exited with code 1

Smartos joyent_20130207T202554Z

vmadm send f59c8669-b709-42cb-98e8-a2f1fa1ee7bf |ssh destination.host vmadm receive

I get this error

vmunbundle exited with code 1

The problem was that, since I was doing some test, there was, on the destination, a zfs dataset for the same zone of a previous attemp.

Solution, on the destination,

zfs destroy zones/f59c8669-b709-42cb-98e8-a2f1fa1ee7bf

SmartOS, kvm, vnc and keyboard

I have had problems with the keyboard using VNC to connect to a KVM guest.
Keyboard mapping I mean.
The solution working for me was:

vmadm update <uuid> qemu_extra_opts="-k it"

linux scp and umask

I use CentOS 5.x
The problem is that if I use scp or sftp to copy a file on such CentOS server, the umask is not taken in consideration.
Behavior of scp and sftp is different.

Btw, a solution is to use openssh 5, but I don't like to alter the distribution, since CentOS 5 install openssh 4.

Using google I've found different solution (pam? etc.) but no one works for me.

So, a way to make what I want is:

For sftp

vi /etc/ssh/sshd_config
# override default of no subsystems
# Subsystem       sftp    /usr/libexec/openssh/sftp-server
Subsystem sftp /bin/sh -c 'umask 0002; /usr/libexec/openssh/sftp-server'

and restart sshd

And for scp

vi /home/myuser/.bashrc

adding (0002 or what you want)

umask 0002
