Description

Tested this between a fedora 20 and ubuntu 14.04 machine. Boost version 1.54.
Using latest version of ndn-cxx and nfd.

Start nfd on laptop
Make sure nfd is not running on the other machine
Try creating a face on laptop: nfdc create tcp4://riker.netsec.colostate.edu
nfd on laptop crashes
Same thing happens when ICMP host prohibited is returned

I cannot reproduce this error on Ubuntu 12.04.
I get a non-fatal error.

shijunxiao@m0212:~$ nfdc create tcp4://192.168.26.13
1404510613.795666 INFO: [FaceTable] Added face id=9 remote=fd://24 local=unix:///run/nfd.sock

Is the "laptop" in the bug running Fedora 20 or Ubuntu 14.04?
Fedora 20 is unsupported.
If it's Ubuntu 14.04, I can try in that system.

Please also attach a tcpdump capture between these two machines at time of bug.

Susmit and I had this happen to NFD instances on both Fedora 20 and Ubuntu 14.04 (the laptop in question is Fedora) trying to connect to a different remote box behind a firewall (don't recall the OS).

In the 14.04 test, the problem persisted after ensuring NFD and ndn-cxx were using the latest git HEADs and clean & distclean re-installations. The thrown exception is caught in main by the catch statement that returns 4.

However, the problem completely stopped and I was unable to reproduce after upgrading the ubuntu machine's boost from 1.54 to 1.55 (uninstall 1.54, 1.55 only). I then attempted to reproduce by uninstalling 1.55 and re-installing 1.54, but could not get NFD to crash (nfdc just receives an appropriate 408 control response).

I'm not sure what to do with this error. It happened reliably on ubuntu 14.04 (multiple clean and reinstalls of NFD and ndn-cxx) until the boost change. However, the NFD on Susmit's Fedora 20 laptop is still reliably crashing. (boost 1.55 is not available through normal yum channels at the moment.)

Please attach a tcpdump capture between these two machines near time of crash, and note the IP address of the laptop.

Please also obtain a backtrace for the bug:

comment out the try-catch block in daemon/main.cpp around io_service.run() (but keep io_service.run()), and recompile NFD
run NFD within gdb, and reproduce the bug; gdb shall pause the process when the crash happens
type bt at the prompt, and paste the output here

Can you try compiling with http://gerrit.named-data.net/#/c/995/ patch set and confirm that the error no longer exists?

Also. Are there other version of boost libraries available?

Not for Fedora 20.

Yes, it does compile and NFD does not crash. Thanks.

However, the error code is a bit strange:

[root@thelaptop html]# nfdc create tcp4://198.129.34.34

ERROR: Face creation failed: Connect to remote endpoint failed: Success (code: 408)

I have confirmed the original error on Ubuntu 14.04 with boost 1.54.0-4ubuntu3

After the update to 1.54.0-4ubuntu3.1 the error does not exist anymore (3.1 package incorporates the fix mentioned in https://svn.boost.org/trac/boost/ticket/8795).
