Hi @ all,
I have a problem with OMV SFTP that I can't explain myself, nor an IT-professional.
A friend of mine have to transfer ~1GB backup-files from his homeoffice to my OMV on Pi4 in my homeoffice.
First we tried normal FTP, but ran into a 2MB/s limit per file Upload. Then I installed the SFTP Plugin, Port 666, but same problem. Still 2MB/s per file.
Then he tried to upload to my external webserver with SFTP: ~5MB/s per file, which is aprox. his upload-limit of his connection.
Then I tried uploading from my pc to OMV via local network via SFTP: 35MB/s per file.
Now I'm confused.
We also tried to use VPN between my FritzBox 7590 router and his PC to avaoid possible ISP limitations to SFTP connections... same. 2MB/s per file and maxed out connection with 3 files at the same time.
I use a Raspi 4 4GB, wired with gigabit to the FritzBox 7590, my Connection is 100Mbit/40Mbit, his connection is quite similar, but mostly a bit better then mine.
OMV, all up2date ( 5.5.23-1) and SSD via USB3 on the Pi. And yes, he's uploading to the SSD, wich isn't the problem because I still can upload with 35MB/s localy.
We used FileZilla Client, WinSCP and a third SSH/SFTP software, all the same.
Does anyone have any explanation, why only his connection to my OMV has a 2MB/s per file limit, but not to an external server nore myself via LAN?
Could it be my ISP with throttling or the router? Or is there any setting I have to set for incoming external IPs in OMV?
If you need any logs or settings, let me know. But please tell me where they are, since I'm not an expert.
