Here are instructions for uploading:

Instructions as follows will show how to use it with the built-in "ftp" command line program that comes with all Windows and Linux systems; feel free to adapt them as necessary for use with other FTP programs.

---------------------------------------------------
-Open a command prompt/terminal window and type the following command:
ftp nplb-gb1.no-ip.org

-ftp will ask for a username. Type "aliquot" (capitals as shown, no quotes) and press Enter.

-ftp will ask for a password. Type "aqupload-4788" (capitals as shown, no quotes) and press Enter.

-ftp will now output the following:
230 Login successful.
ftp>

-Type "cd c140-relations" and press Enter.

-Type "binary" and press Enter.

-Now type the following command:
put relations.gz
...replacing "relations.gz" with the name (and, if necessary, pathname) of the compressed relations file you're uploading. Tip: navigate to the directory your relations file(s) are in *before* starting the FTP command, so you don't have to type long and clumsy file paths in your "put" commands for each file you upload.

-Wait until the file's finished uploading. Depending on the size of the file, it may take a while; please note that ftp doesn't show any progress or status info until the upload has completed, so it can appear to be "frozen" if you haven't used ftp before.

-Verify that your file's made it to the server by typing the command "ls" and seeing if your file shows up in the directory listing that results. If you see, it, you're all set!

-Type "quit" and press Enter. Close the command prompt/terminal window.

I'll run msieve with (pulling numbers from air) 815000 to 824999.

Just moving this down to re-use the second message....

[schickel]

Here is the best GGNFS poly after 6 hours. I plan on leaving this running overnight and seeing if anything better pops out.

And my recollection was incorrect, the "good score" value was 1.60e-11

[henryzz]

reserving 10k-11k for msieve poly selection

[fivemack]

I believe in surprisingly small a5, so would like to reserve 1-10000

after running with "msieve -v -np 10000,11000 -m" i got:

does this mean there is no polynomial that msieve can find with default params in that range?

[smh]

As a test i ran 1 to 3000 in stages, but i also get

That is a good poly, smh.

My best was a 1.931727e-11.

edit: search ran for 9.5 hours.

Now I am searching 330000 to 334999 with msieve.
