So since there is no telnet on the DS2000 series I searched around and found vxi11 by a fellow forum member alex.forencich and I modified the script to use that instead.
Do not jump with joy yet because the DS2000 series seems to be transferring data at 56Kbps via the Ethernet port (the old Kbps as in 1024 bps). Since the DS2000 only saves as a BMP 800x480x3 plus the BMP header 1152067 bytes, the total transfer size is 9216536 bits.
Divided by 57344 bps is equal to ~161 seconds.
So it takes 2 minutes and 41 seconds to transfer the screen. No wonder others using USB have faster transfer times. Haven't found a way to speed the Ethernet port or change it to png or jpeg (other than converting the screenshot later on to png or jpeg)

Here is the screenshot after I used paintshop pro to convert it from the huge bmp to just an 18KB png picture.
@bingo, how fast is the screen capture on the DS1000z scope? I would think that because it supports png it's probably about 5.5 seconds to transfer a 37KB file already in png format but still transferring data at a mere 57344 bps
Edit: yeah, I had the ratio set to just 1X not sure why, so that's really 3Vpp.
Apologies for the slight OT, but curious if the Ethernet speed is the same via telnet as it's with LXI
