Hello,
I try to transfer files using sftp between the following machines :
- my pc, redhat 6.2, kernel upgraded to 2.4.2, openssh 2.5.1 p2 installed
from redhat 6.2 rpms.
- a distant machine wich is a pc running under redhat 7, with ssf 1.2.27.6
installed (the french version of ssh - complying with french
cryptography laws).
(exact version of ssf :
SSH Version SSF-1.2.27.6 [i686-unknown-linux], protocol version 1.5.
Standard version. Does not use RSAREF.)
ssh works fine in both directions. When using sftp, I must add option -1
because ssf knows only ssh protocol version '1.5'. It fails nevertheless in
both directions :
from my computer :
> sftp -v -1 peyotl.polytechnique.fr

The command that should be executed on the remote host
(usr/libexec/openssh/sftp-server) does not exist. I have tried to give sftp
the correct argument to pass to ssh in order to change
/usr/libexec/openssh/sftp-server in 'sftpserv', which is the command which
probably must be executed remotely, but I did not manage to do so (in fact, I
looked in the binary file of sftp and I saw that the command seemed
hard-coded in it)
In the opposite direction, the same kind of problem occurs ; sftp tries to
remotely execute sftpserv, which doesn't exist on my computer :
> sftp -v bellaciao.homeip.net
Enter passphrase for RSA key '[EMAIL PROTECTED]':
Warning: Remote host denied X11 forwarding, perhaps xauth program could not
be run on the server side.
bash: sftpserv: command not found
read: Input/output error
Does anybody know a solution for that problem ?
Do I need to recompile sftp, and change the name of the remote command to be
executed ? Is it pointless to do that for some reason I ignore ?
Thanks,
Sébastien Kunz-Jacques
