Transfering more than 2 files at the same time on SFTP (SSH) thru FileZilla

[htcz]

Hey

How can I transfer more than 2 files at the same time on SFTP (SSH) thru FileZilla? Is there a option? Or is it a server limitation?

Thank you!

Open the file preferences and look for the maximum number of simutainious connections.

Unless you own the server or have full control over it I wouldn't really recommend it, if it's leased then chances are it's got a standard rule to block any IPs connecting more than a few times in 5 minutes to SSH ports.

It seems the limit is only 4 transfers at a time. If I put it at 10 (max permitted) only 4 at a time say "Transfering" (The rest say connecting) so.....I put it at 4 and its doing OK and a bit faster :)

Unless you have somehow shaped connection (or the server does it on its own), you shouldn't get higher speeds from multiple connections - it'll just transfer the files and split the bandwidth amongst them.

With lots of small files you could get faster overall transfer... otherwise it has start/stop times while going 1 (pause) 2 (pause) 3 (pause). Same happens with XCOPY/ROBOCOPY in windows. No large benifits with large files, but drastic improvement on small ones.

Exactly. For small files this is great and indeed has sped up the transfer drastically.

If you have lots of small files to transfer you know what also makes it faster! Tar them up or zip/gz them etc.. into one larger file and then copy it, then expand them back out ;)

I just raise mine until I started getting errors transferring files. On my home connection that is 5. At work I do 10. That is to the same FTP server.

Thats one of those ideas that is actually crazy enough to work. :p

What formats does tar support? I was going to transfer a 7zip (most compressed) but not sure if tar supports it.

What??

just 7z if your files if that is what you want? What does tar have to do with that if your going to use 7zip?

.tar (known as a "tarball") is an alternative to .zip and .rar

That would be my fault for not mentioning it :p

I only have access to a bash shell to where I transfer the file. There, I have the tar and the unzip utilities (AFAIK). Thats why behind my question :)

tar is also a program on unix, which is what i have a SSH shell to.

I apoligize for not explaining correctly what I have access to.

can you add stuff to this remote ssh box? So you can use what you want? But zip should be a given that should there.

here is my remote host shell account - it has an unzip support.

You normally can create .tar file on windows as well with pretty much any zip program. Here 7zip shows it can pack .tar and gzip, etc.

Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM

So you should be able to create with 7zip and then expand it on your host.

I couldnt find a way to create a tar in 7zip

I am using your advice of zipping it all up and extracting it server side. But today the transfer is painfully slow :( The other day it took 15 minutes. Today 45 mins :(

What type of OS are you running on the server and client, and what type of file transfers is it (If you're transferring it every day, is it something like log files or such?)

If it happens on a set schedule and you can get rsync on the client and server that would probably be the best bet, it can compress the data it transfers and can do delta encoding (so it only sends the differences), and it can use SFTP underneath so it's secure to boot.

"I couldnt find a way to create a tar in 7zip"

But you don't have to tar it, you could just gzip it. or bzip2 is another one that is most likely on any linux distro.

But you can create your tar if you want, and then gzip the tar so you end up with tar.gz, etc..
