[Bug 2272] New: Global PermitTunnel Yes required to connect to a tunnel

2014-09-09 Thread bugzilla-daemon
https://bugzilla.mindrot.org/show_bug.cgi?id=2272

Bug ID: 2272
   Summary: Global PermitTunnel Yes required to connect to a
tunnel
   Product: Portable OpenSSH
   Version: 6.6p1
  Hardware: amd64
OS: Linux
Status: NEW
  Severity: major
  Priority: P5
 Component: sshd
  Assignee: unassigned-b...@mindrot.org
  Reporter: joe9m...@gmail.com

Hello,

When a tun0 device is created with the below commands on the server:

ip tuntap add dev tun0 mode tun user sshuser group sshusers
ip link set dev tun0 up
ip addr add dev tun0 local 10.8.0.1 peer 10.8.0.2


and ssh is started with this command from the client:

ssh -NTC -w 0:0 -o Tunnel=point-to-point sshuser@ip-address

Working extract from sshd_config:

PermitTunnel yes
Match User sshuser
   PermitTunnel yes

NOT Working extract from sshd_config (below is the message):
PermitTunnel no
Match User sshuser
   PermitTunnel yes

The error message with a -v is:
debug1: Remote: Server has rejected tunnel device forwarding

Thanks
Joe

[Bug 2273] New: The group of the tunnel device needs to match with the group of the connecting ssh user

Bug ID: 2273
   Summary: The group of the tunnel device needs to match with the
group of the connecting ssh user
   Product: Portable OpenSSH
   Version: 6.6p1
  Hardware: amd64
OS: Linux
Status: NEW
  Severity: normal
  Priority: P5
 Component: sshd
  Assignee: unassigned-b...@mindrot.org
  Reporter: joe9m...@gmail.com

Hello,

When a tun0 device is created with the below commands on the server:

$ id sshuser
uid=100(sshuser) gid=100(sshusers) groups=100(sshusers)

$ ip tuntap add dev tun0 mode tun user sshuser group users
$ ip link set dev tun0 up
$ ip addr add dev tun0 local 10.8.0.1 peer 10.8.0.2

and ssh is started with this command from the client:

$ ssh -NTC -w 0:0 -o Tunnel=point-to-point sshuser@ip-address

The error message is:

debug1: Remote: Failed to open the tunnel device.
.
.
.
channel 0: open failed: administratively prohibited: open failed
debug1: channel 0: free: tun, nchannels 1

If the group of the tun0 device is changed from users to sshusers,
the above ssh connection works fine.

Thanks
Joe

--- Comment #1 from Damien Miller d...@mindrot.org ---
Yes, that's working as intended. sshd should refuse tunnel connections
unless the administrator has explicitly configured it. This is already
mentioned in the sshd_config manual.
