Package: nbd-server Version: 1:3.2-4~deb7u4 Severity: important Dear nbd maintainer
Since the latest security update my clients cannot connect to the nbd-server.
-----------/etc/nbd-server/config---------
[generic]
[backup]
exportname = /dev/winuserfs_vg1/storebackup
authfile = /etc/nbd-server/allow
-----------
-----------/etc/nbd-server/allow---------
130.149.125.113
---------------------------------------------------
On the client:
$ nbd-client -N backup winuserfs /dev/nbd0
Negotiation: ..size = 13216954585799MB
bs=1024, sz=13858981371759755264 bytes
On the server gives the following entry in the log.
Dec 7 16:42:50 winuserfs nbd_server[4359]: connect from 130.149.125.113,
assigned file is /dev/winuserfs_vg1/storebackup
Dec 7 16:42:50 winuserfs nbd_server[4359]: Unauthorized client
-------------------------------------------------------------------------
Same in the oldstype case:
-----------/etc/nbd-server/config---------
[generic]
oldstyle = true
[backup]
exportname = /dev/winuserfs_vg1/storebackup
port = 20000
authfile = /etc/nbd-server/allow
-----------
-----------/etc/nbd-server/allow---------
130.149.125.113
---------------------------------------------------
On the Client:
$ nbd-client winuserfs 20000 /dev/nbd0; mount -t ext4 /dev/nbd0
/mnt/winuserfs_backup
Negotiation: Error: Server closed connection
Exiting.
On the server gives the following entry in the log:
Dec 7 16:47:18 winuserfs nbd_server[4424]: connect from 130.149.125.113,
assigned file is /dev/winuserfs_vg1/storebackup
Dec 7 16:47:18 winuserfs nbd_server[4424]: Unauthorized client
If I start the server without /etc/nbd-server/allow connection works.
Dec 7 16:54:29 winuserfs nbd_server[4516]: connect from 130.149.125.113,
assigned file is /dev/winuserfs_vg1/storebackup
Dec 7 16:54:29 winuserfs nbd_server[4516]: Can't open authorization file
/etc/nbd-server/allow (No such file or directory).
Dec 7 16:54:29 winuserfs nbd_server[4516]: Authorized client
Dec 7 16:54:29 winuserfs nbd_server[4519]: Starting to serve
Dec 7 16:54:29 winuserfs nbd_server[4519]: Size of exported file/device is
114890375168
Downgrading to 1:3.2-4~deb7u3 also solves the issue
In the Oldstyle case the log gives:
Dec 7 17:04:30 winuserfs nbd_server[5038]: connect from 130.149.125.113,
assigned file is /dev/winuserfs_vg1/storebackup

Dec 7 17:04:30 winuserfs nbd_server[5043]: Starting to serve
