Public bug reported:
Hey guys, I have a very weird issue here. PPP works fine for 1-5
minutes, then it hangs with CPU usage very high, and I noticed it start
uploading insane (but fake) bytes to the tunnel. To do a simple test, I
started watching a YouTube video, and when the problem started to
happen:
ppp0 Link encap:Point-to-Point Protocol
inet addr:172.16.99.9 P-t-P:xxx.xxx.xxx.xxx Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1400 Metric:1
RX packets:26586 errors:0 dropped:0 overruns:0 frame:0
TX packets:5921622 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:35077655 (35.0 MB) TX bytes:2885396935 (2.8 GB)
Then it crashed, and VPN turned itself off. I tried everything: MTU,
tunnel parameters etc. Please note I am a guy with 20+ years experience
in networking and I own an IT company. This is definitely a BUG of PPP.
It started happening since Ubuntu 16.04, before I never had this issue.
Description: Ubuntu 16.04.2 LTS
Release: 16.04
PPP: 2.4.7-1+2ubuntu1
Cheers,
Simone
