[Testbed-admins] Interface Re-numbering Error

[Barry Trent <btrent@triticom.com>]

I'm trying to add a new net of nodes to my Emulab. They have 7 Ethernet 
interfaces and, unlike nodes I have previously added, FreeBSD and Linux 
number these interfaces differently. Using the web interface page for 
New Testbed Nodes, I tried to enter the required remapping of interfaces:

(FreeBSD:Linux)
0:5
1:6
2:0
3:1
4:3
5:4
6:2

When I select the button to re-number the interfaces, I get an error 
message:

Could not continue. Please contact  Testbed Operations 
(testbed-ops@emulab.atcorp.com)

And an email with the following error message is delivered to the 
testbed-ops account:

In 
/newnodes_list.php3?selected[]=65&newtype=&newprefix=&addnumber=&remap[0]=5&remap[1]=6&remap[2]=0&remap[3]=1&remap[4]=3&remap[5]=4&remap[6]=2&remap[6]=&renumber=Re-number 
interfaces of selected nodes

DB Query failed - In /newnodes_list.php3
  Query: UPDATE new_interfaces SET card = 6 WHERE card = 101 AND 
(new_node_id=65)
  Error: Duplicate entry '65-6' for key 1

Interesting that I left box 7 on the web page blank, but the last 2 
"&remap[n]=" clauses in the form submission both seem to reference 
"&remap[6]". Shouldn't those last two be "&remap[6]=2&remap[7]=" instead 
of "&remap[6]=2&remap[6]=" ?

I just looked a bit deeper and it looks like a "cut-and-paste" bug in 
the newnodes_list.php3 script to me:

<tr>
    <td>6</td>
    <td><input type="text" size=2 name="remap[6]"></td>
</tr>
<tr>
    <td>7</td>
    <td><input type="text" size=2 name="remap[6]"></td>
</tr>


Should I just edit the script and try again? Is this a known bug?
