sftp-server

sopiaz57 · 01-02-2004, 08:06 AM

can someone help me out?

I am running ssh, trying to connect to do sftp.

1. i have the sshd_config file uncommented in the line:

Subsystem sftp /usr/libexec/openssh/sftp-server

2. I am trying to connect from my windows box using a sftp (from sourceforge) client, which says this after I login with my user and pwd:

Unable to connect:
Received too large (1852139884 B) SFTP packet. Max supported packet size is 102400 B.

What client are you using? Does your client do "scp/sftp over ssh" or "ftp over ssl/tls"? They're similar file transfers, but use two different sets of ports?

I've always like PSFTP - The whole suite is sweet.

A most excellent client can be found here. It is called WinSCP, but it also supports SFTP:

Yes Paul, I am using that program. Got it off sourceforge the other day. Dont know why it wont work though.

I am using a non standard ssh port though, could that be the problem?

Yeh, this will probably be the exact problem. WinSCP has the option to change the port though when you enter your login details. Try that.

I did connect and got everything working, but im confused. In winSCP, i chose the protocol "SCP"

I was trying to use "SFTP" protocol, shouldnt SFTP work also?

thanks

Yes they should both work. When I did an out of the box install if RH8 i didnt have to do any special configuration to get SCP and SFTP working so I dont understand why you are having this problem.

It maybe that your paths for the

Subsystem sftp /usr/libexec/openssh/sftp-server

entry are wrong. My RH8 installation does not have /usr/libexec/openssh/sftp-server but has /usr/bin/sftp. Try commenting the line that you uncommented again as it maybe conflicting with the default config. Then tell me your findings...

Is one of the protocols better than the other?

SCP VS SFTP?

------------------

My binary and the sshd config file seem to match:

Subsystem sftp /usr/libexec/openssh/sftp-server
locate sftp-server = /usr/libexec/openssh/sftp-server

Quote:

My RH8 installation does not have /usr/libexec/openssh/sftp-server but has /usr/bin/sftp

this is because the sftp binary is the client program.

My mistake, i do have /usr/libexec/openssh/sftp-server

Try commenting the sftp-server line out and see if it works.

As for SCP vs. SFTP: http://www.linuxquestions.org/questi...003/07/2/70685

commented the line out, says this when i try to connect via "SFTP":

Cannont initialize SFTP protocol. Is the host running a sftp server?
Received too large (1852139884 B) SFTP packet. Max supported packet size is 102400 B.

When i choose , SFTP (allow SCP fallback) it works , naturally because SCP still works.

Thank you for your help
