参考
I had the same issue after a client update of the cifs-utils to 6.7-2. And basically the solution from josepcoves and user695658 worked for me. But only the value 1.0 for the mount option 'vers' worked for me. It seems like the default value for the param 'vers' is not 1.0 anymore.
その他mountオプション
vers指定(1.0〜3.0まである様子)
mount -t cifs -o vers=1.0
詳細表示
# user名が表示されるのは便利
mount --verbose
ゲストとして接続
mount -t cifs -o guest
port
mount -t cifs -o port=445
netbios名で指定
mount -t cifs -o netbiosname=server1
mode指定
mount -o dir_mode=0777,file_mode=0777
スペース入れられる様子
mount -t cifs //Server-IP-Address/Share-Name \
-o username=name, password=password /winmount/Share-Name
文字コード指定
mount -t cifs -o codepage=cp932,iocharset=utf8
