Hi List,

I am not expert at all about syslog files. I do not know what file I have to change to log what file are uploaded or downloaded from my PC using SCP and SFTP, just like I did when I was using FTP.

As a start, read the man pages for ssh, sftp, and scp. There is the -v option to increase the logging level. So you might run the commands as "sftp -v"; you could even set an alias for it in /etc/profile so that "sftp" = "sftp -v" -- $|=1;while(1){print pack("h*",'75861647f302d4560275f6272797f3');sleep(1); for(1..16){for(8,32,8,7){print chr($_);}select(undef,undef,undef,.05);}}
