Cannot mount Windows 98 SE share over SSH to Ubuntu 14.04

You’re running the mount command as root and haven’t specified a different username. You can add username=user to the -o list (where user is the username on target machine):

sudo mount -t cifs //192.168.0.2/uniserv /tmp/uniserv/ -o username=user,sec=lanman,servern=Uniplus1

If you want to connect to the share as a guest, use guest instead of username=user in the -o list:

sudo mount -t cifs //192.168.0.2/uniserv /tmp/uniserv/ -o guest,sec=lanman,servern=Uniplus1

If the server gives information about ownership and permissions, mount.cifs will try to respect it. Otherwise, all files and directories in the share will be owned by root, and accessible only by root. If you don’t want that, you can add use the uid and or gid arguments to specify user or group IDs. A common way is uid=$UID. For example:

sudo mount -t cifs //192.168.0.2/uniserv /tmp/uniserv/ -o guest,uid=$UID,sec=lanman,servern=Uniplus1

The UID environment variable is a bashism (also in zsh), so if you’re invoking this command from a shell that doesn’t support it (such as dash, which provides sh in Ubuntu), use $(id -ru) instead (or manually put in your actual user ID number from /etc/passwd):

sudo mount -t cifs //192.168.0.2/uniserv /tmp/uniserv/ -o guest,uid=$(id -ru),sec=lanman,servern=Uniplus1

Source: Mainly man mount.cifs.

If you’d prefer to perform the mount operation itself as a regular (non-root) user, How do I mount Samba share as non-root user may help.
