[Proftpd] Internal (LAN) access capped at 2MB/S?

joekr · 07-10-2005, 05:15 PM

Hey all

I have a 100Mbit/s home lan. One box is set up with proftpd. Downloading and uploading from/to proftpdbox (from other computers IN LAN ie internal) is capped at ~2000kb/s. The speed should be 4-5x that!

Code:

ServerName                      "joe's ftp running on gentoo"
Bind                            "192.168.1.102"

Any help would be appreciated.

That may be caused by hub bandwidth being shared with other traffic...

Good call, however that isn't the case in this particular situation... I can ftp to an xbox (also on the lan) and upload at ~8-9 megabytes/s.

In addition, I powered down all boxes on the lan except the proftpdbox and my primary workstation (thus ensuring no bandwidth is being used elsewhere) and still I only get transfers up to 2000kb/s.

From the ftp box, could you upload to the xbox to check speed ?
Also I noticed in your proftpd.conf (at the bottom) :

<Limit READ WRITE DIRS STOR CWD CDUP>
AllowAll
</Limit>

Souldn't it be :
<Limit READ WRITE DIRS STOR CWD CDUP>
Allow from All
</Limit>

FTPbox to xbox yields 367602169 bytes sent in 52.7 secs (6.8e+03 Kbytes/sec)

Speed looks OK... also worth mentioning all nics are connected at full duplex... I believe this isolates the problem to a configuration-error in proftpd.

The last few lines you mentioned above don't affect transfer rate... they are limits placed on users (or in this case no limits) as to what commands they are allowed to issue.

Also worth mentioning is I tried changing TransferRate STOR 0 to TransferRate STOR 20, and I successfully lowered my upload cap to 20kb/s. However, when changing it to TransferRate STOR 10000 (setting it to 10mb/s) the speed is still capped at 2000kb/s.
