SSTP: sstp-client for linux not working properly?

RouterOS General
1

Hi there,

I’am trying to connect with the linux sstp-client to on of my ROS 5.14 RB750G. If I crank up the client manually with:
sstpc --ca-cert ca.crt --user michael --password supersecret test.bwc.internal

the connection works for exactly 60 seconds and goes down with:
**Error: Connection was aborted, Reason was not known, (-1)

Why does the connection gets terminated after 60 seconds, which looks like a timeout?

/interface sstp-server server
set authentication=pap,chap,mschap1,mschap2 certificate=sstp default-profile=
default enabled=yes keepalive-timeout=120 max-mru=1500 max-mtu=1500 mrru=
disabled port=443 verify-client-certificate=no

The log is telling me this:

Try to run sstpc via sudo.

I’am always running in sudo :slight_smile:

It seems to be a bug in linux SSTP client. It does not send one packet needed to finalize ppp negotiation.

Hi,

thanks for the update, I tried on Ubuntu 10.04 and 12.04 (alpha/beta) with the same result.

Is anybody else using sstp-client on linux with success?

try to enable only pap authentication on sstp server and then try to connect.

7

Nope, same result with just PAP selected, 60 seconds it is.

I have exactly the same issue here.

Everything fine for 60 seconds and then:

: terminating… - negotiation timeout
: disconnected

The client works fine against Windows 2008 sstp server.

Any ideas ??
Thanks.

Hey Guys,

I have hit this problem in a different scenario. All my routers where running 5.26, and I have upgraded one router acting as sstp client to 6.10 and I am seeing the exact same problem.

Any Ideas?

Thanks,

Same problem, 6.10 after update SSTP abort connections after 60 sec

As it was mentioned in one of previous posts. It is a bug in linux sstp client implementation.
