Hi Kern,

About your ssh Xforwarding issue...
You need to add the following line to your /etc/sshd_config file:

X11Forwarding yes

then just ssh to the remote machine using:

ssh -X remote-machine

and you should be able to run remote graphical apps using your local Xserver. 
Note that this is usually disabled by default because it is a security risk. 
But for machines on a trusted lan, it is not much of an issue. I am surprised 
that Red Hat would have Xforwarding turned on by default.

Disclaimer: I use Debian, so it may be different under SuSe (but most likely 
this should work).

Cheers,
Silas Bennett

Subject: [Bacula-users] Bacula Migration project status + misc


Hello,

Migration:
This is to let you know that the Bacula migration project is advancing nicely, 
though it is about 6 weeks behind schedule mostly due to an unplanned 1 month 
vacation and 2 weeks of little work because of a virus.

I've now got all the basic parts working quite well and they pass two new 
migration regression scripts, the first of which does two backups, then 
requests a migration of all jobs named *save, and finally does a restore. The 
second does several backups, then requests a migration of all volumes named 
Full* (or something similar), and then does a restore from one of the 
migrated jobs.  

There are many other forms of migration, but they should be completed rather 
quickly as most are just a question of getting the SQL correct.  

More problematic will be to try to detect and avoid as many Volume/drive 
deadlock situations as possible.  Currently Bacula has no Volume/drive 
deadlock detection, because it has not been really critical, but with 
migration, if you try to migrate from a Volume onto the same Volume, a 
deadlock will arise since it is not possible to read from and write to the 
same volume simultaneously (at least if it is a tape).

Over the next week, I am going to try to verify that the database schema as 
exists today is complete and that the upgrade scripts (untested) work.  Once 
that is done, and I document migration a bit, we can begin making beta 
releases.

Restores:
Recently in thinking about restores and looking at the current Bacula tree 
routines, I am convinced that it is relatively easy to make the current 
Bacula restores optionally function in an incremental manner -- that is to 
load one directory at a time as the user accesses that directory.  This means 
that a user with 6 million files in a Job could rather quickly do a Bacula 
in-memory tree restore in selecting only one or two directories or 
alternatively a few files.  It would not be necessary to load the whole 6 
million file entries in memory before the selection process can begin.

Unfortunately, if we are going to release version 1.40.0 before the end of the 
year, this new idea must be put on the shelf until later.

Best regards, 

Kern


Trivial stuff, but a bit incredible:
As most of you know, I have been slowed down because of what I call a dark 
cloud hanging overhead consuming my time with problems (hardware, software).  
Well, the cloud still seems to be here, but it is not striking me personally 
anymore. Since getting my Autochanger repaired, disabling a bad DVD drive, 
and switching distros, I have had essentially zero problems other than the 
normal learning curve for the new distro.  

On the other hand, the cloud has struck a charitable organization about 300 
meters from where I live, where I happen to do volunteer system 
administration (as well as Bacula backups, of course). First their firewall 
apparatus went belly up, and when I replaced it with a brand new one, I found 
the server dead.  Well, the server, though limping along, is now suffering 
from bus errors, and dying once a day.  Though the cloud is not longer 
striking me, I am still spending a lot of time resolving the damages caused 
by this cloud ...   It is about time it moved on, and hopefully it will take 
the hot weather with it ... :-)

PS: more trivia while I have you on the line:
If anyone on the list understands X privileges, perhaps you could point me to 
what needs to change to make X work between machines.  Previously, I could 
always run a graphical program on any of my computers on my network from my 
development desktop after sshing to the remote machine. Now I find running as 
non-root:

  (on SuSE machine)
  ssh Fedora-machine
  yumex (a Python program that uses GTK)
   yumex
You are attempting to run "yumex" which requires administrative
privileges, but more information is needed in order to do so.
Password for root:
Traceback (most recent call last):
  File "/usr/share/yumex/yumexmain.py", line 24, in ?
    import gtk
  File 
"/usr/src/build/612051-i386/install/usr/lib/python2.4/site-packages/gtk-2.0/gtk/__init__.py",
 
line 37, in ?
RuntimeError: could not open display

Normally the "Password for root:" should be in a GTK window.

Or even an ssh from SuSE to SuSE, and execute a Graphical program, I get:

kile: cannot connect to X server

Groan.  I wonder if Novell knows what networking is.  :-)
