Unpack the RPC response data error

Dear CharmingYang, I meet a problem while using your NfsClient library. Could you help me to see this problem. I use your sample code like this. When it getport from 10.232.94.126, it can get the correct port 635 from the NFS server (I print it)

mnt_port = portmap.getport(Mount.program, Mount.program_version)

However when running the mount

mnt_res = mount.mnt(mount_path, None)

the RPC cannot unpack data correctly, it seems the data format is wrong but I don't know why.

Looking forward for your reply!

The Code written like this:

# variable preparation
host = "10.232.94.126"
mount_path = "/vol_log/VASC_SILA/VMS/VMSKPI"

auth = {
    "flavor": 1,
    "machine_name": "maccrt03",
    "uid": 0,
    "gid": 0,
    "aux_gid": list(),
}

# portmap initialization
portmap = Portmap(host, timeout=3600)
portmap.connect()

# mount initialization
mnt_port = portmap.getport(Mount.program, Mount.program_version)
print("mnt_port")
print(mnt_port)
mount = Mount(host=host, port=mnt_port, timeout=3600, auth=auth)
mount.connect()

# do mount
mnt_res = mount.mnt(mount_path, None) # Have problem
print(mnt_res)
