If your work on AIX System (or any other UNIX/Linux Distribution), may be you face the following Message when you try to access SFTP:
Couldn't canonicalise: Permission denied Need cwd
after many troubleshooting :
– user can access SSH without any problem.
– user can’t access SFTP
– you can switch on this user normally.
after analysis the problem and search on the internet (reference is below), we found that:
the user which we try to connect SFTP using it, his home directory is a file system ( which is normal ) & we found that the file system owned by this user (which is also normal) but the base directory (the normal directory after umount the file system) with a different permissions.
now the Technical Steps:
#sftp user1@10.40.40.60 user1@10.40.40.60's password: Connected to 10.40.40.60. Couldn't canonicalise: Permission denied Need cwd #ls -ld /user1 drwxr-xr-x 13 user1 usergroup 4096 Jan 10 08:17 /user1 #umount /user1 #ls -ld /user1 drwxr-x--- 2 202 204 256 Apr 11 2015 /user1 #chown user1:usergroup /user1 #ls -ld /user1 drwxr-x--- 2 user1 usergroup 256 Apr 11 2015 /user1 #mount /user1 #ls -ld /user1 drwxr-xr-x 13 user1 usergroup 4096 Jan 10 08:17 /user1
I hope this be useful.
