[cobalt-users] FTP weirdness

["Mike Smith" <msmith645@xxxxxxxxxxx>]

A client of mine has been testing a shell script from their linux box (not 
on the same network as my Raq4i's)....the shell script performs a backup 
from their linux box to their domain via ftp. This client has 2 domains, and 
due to the fact that no user can have the same "user name" on a Raq4, this 
is how things are setup (names are changed to protect the innocent):
  first domain: my-domain-number1.com
  user/siteadmin: jsmith
  password: 12345
  second domain: my-domain-number2.com
  user/siteadmin: smith
  password: 12345

Here's the weird part....in the shell script, the user was to connect via 
ftp to "my-domain-number2.com", but inadvertently used his user name for 
site#1....when the script connected, it actually sent the user to 
"my-domain-number1.com" even though "my-domain-number2.com" was specified as 
the domain to which it should connect. The shell script performed as it 
should, uploading files to the (wrong) domain. This was only brought to my 
attention when the Raq4 sent an email for domain number #1 being over quota.
Curiosity led me to attempt to do the same via a windoze ftp client. I set 
the windoze ftp client to connect to "some-domain.com" using a login and 
password for a _different_ domain "some-other-domain.com" (on the same 
server)....when the ftp client connected, it appeared to connect to the 
_proper_ IP address for "some-domain.com" yet the directories and files were 
those for "some-other-domain.com" !
It appears that no matter which domain name is placed into the ftp client, 
if the login and password are _that_ of another domain on the SAME machine, 
the ftp client will connect to the _other_ domain.
This does not happen across different Raq's, I tried that, it only happens 
for domains on the same box.

Anyone ever seen this before? It looks like a security issue to me, but I 
could be wrong.
If I haven't been very clear, please do not hesitate to contact me and I 
will attempt to explain it a little better.

TIA,
Mike
