Any suggestion on Capturing SFTP error in log ???
Hello All,

I have searched the thread for capturing and got some suggestion but that is not working for me.

I am trying to sftp to a window server from unix server and getting file there with out any issue .But i wan't to capture the error --in case a file is not exist in remote.

Example :
I tried the script following way
1) cat sftp_transfer.ksh

2>&1
sftp -b trfr_Files.sftp servername

2) cat sftp_transfer.ksh

sftp -b trfr_Files.sftp servername >error.sftp


==========
Surprisingly in both the case the error is not redirecting to the file .
In second part only success full file transfer are recorded in logfile but not error.
When ever some file is not present it is straight way throwing the error to the STDOUT.

$ ./sftp_transfer.ksh
Error :

Couldn't stat remote file: No such file or directory
File "/logs/test//xxxx_172.18.127.2_20080526.txt1" not found.

Any suggestion how to redirect the erro part or all of the output and error to a logfile .

***Note the trfr_Files.sftp contain the list of get file from the server****
Script working fine only thing i am not able to redirect the error part to a log.

sftp-server

SFTP-SERVER(8)						    BSD System Manager's Manual 					    SFTP-SERVER(8)

NAME

     sftp-server -- SFTP server subsystem

SYNOPSIS

     sftp-server [-ehR] [-f log_facility] [-l log_level] [-u umask]

DESCRIPTION

     sftp-server is a program that speaks the server side of SFTP protocol to stdout and expects client requests from stdin.  sftp-server is not
     intended to be called directly, but from sshd(8) using the Subsystem option.

     Command-line flags to sftp-server should be specified in the Subsystem declaration.  See sshd_config(5) for more information.

     Valid options are:

     -e      Causes sftp-server to print logging information to stderr instead of syslog for debugging.

     -f log_facility
	     Specifies the facility code that is used when logging messages from sftp-server.  The possible values are: DAEMON, USER, AUTH,
	     LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.  The default is AUTH.

     -h      Displays sftp-server usage information.

     -l log_level
	     Specifies which messages will be logged by sftp-server.  The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
	     DEBUG2, and DEBUG3.  INFO and VERBOSE log transactions that sftp-server performs on behalf of the client.	DEBUG and DEBUG1 are
	     equivalent.  DEBUG2 and DEBUG3 each specify higher levels of debugging output.  The default is ERROR.

     -R      Places this instance of sftp-server into a read-only mode.  Attempts to open files for writing, as well as other operations that
	     change the state of the filesystem, will be denied.

     -u umask
	     Sets an explicit umask(2) to be applied to newly-created files and directories, instead of the user's default mask.

     For logging to work, sftp-server must be able to access /dev/log.	Use of sftp-server in a chroot configuration therefore requires that
     syslogd(8) establish a logging socket inside the chroot directory.

HISTORY

     sftp-server first appeared in OpenBSD 2.8.
