smbclient는 작동하지만 mount.cifs는 작동하지 않습니다. (NT_STATUS_MORE_PROCESSING_REQUIRED)

SMBv1을 사용하여 이전 컴퓨터에서 파일 공유에 액세스하려고 합니다. 이 컴퓨터는 물리적으로 접근할 수 없지만 Windows XP를 실행하고 있는 원격 컴퓨터입니다.

를 사용하면 잘 액세스할 수 있습니다 smbclient '\\172.25.162.14\nda20' -N -m NT1 --option="client min protocol"=NT1. 그러나 mount.cifs를 사용하여 마운트할 수는 없습니다. 몇 분 동안 그대로 있다가 마침내 다음과 같이 표시됩니다.

> mount -t cifs -vvvv //172.25.162.14/nda20 /mnt/aa -o vers=1.0,guest
mount.cifs kernel mount options: ip=172.25.162.14,unc=\\172.25.162.14\nda20,vers=1.0,user=,pass=********
mount error(11): Resource temporarily unavailable
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

디버깅을 활성화하는 경우:

echo 7 > /proc/fs/cifs/cifsFYI
echo 1 > /proc/fs/cifs/traceSMB

그러면 dmesg다음과 같이 표시됩니다.
