Pulling/pushing data to a samba server from Linux

smbclient (It's atrociously formatted man page is here) will let you do what ftp let you do which is to get and put files from you local machine to a samba server.

My use case is that I have a high performance cluster (Partners' Linux High Performance Computing cluster) that I want to run my code on (remoteA) while my data is on another server (remoteB) that seems to only allow access through samba and refuses ssh and scp requests.

The solution turns out to be to use smbclient, which seems to behave just like the ftp clients of old.

ssh into remoteA

smbclient \\\\{machine name}\\{share name} -D {my directory} -W{domain}

(The multiple backslashes turn out to be vital)
You'll end up with a smbc prompt. At the prompt type

prompt  (Gets rid of the prompt asking you if you are sure you want to copy or EVERY file)
recurse  (I wanted to copy a whole directory, so I needed this)
mget <my dir>\  (this is my directory)

A useful command is

smbclient -L {machine name} -W {domain}

which lists the share names available on the machine

A note on Python's __exit__() and errors

Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or

Using adminer on Mac OS X

adminer is a nice php based sqlite manager. I prefer the firefox plugin "sqlite manager" but it currently has a strange issue with FF5 that basically makes it unworkable, so I was looking for an alternative to tide me over. I really don't want apache running all the time on my computer and don't want people browsing to my computer, so what I needed to do was: Download the adminer php script into /Library/WebServer/Documents/ Change /etc/apache2/httpd.conf to allow running of php scripts (uncomment the line that begins: LoadModule php5_module Start the apache server: sudo apachectl -k start Operate the script by going to localhost Stop the server: sudo apachectl -k stop
