Closed lvalero closed 9 years ago

Hello,

difficult to spot the source of the problem, when upgrading to v1.3.0, i opened a project made with previous version (made of vbox + IOU) and i got that message trying to start IOU devices :

Server error from 127.0.0.1:8000: IOU5: Could not start iouyap: [Errno 8] Exec format error

on terminal more output : 2015-03-31 11:08:11 ERROR route.py:145 VM error detected: <class 'gns3server.modules.iou.iou_error.IOUError'> Traceback (most recent call last): File "/usr/local/lib/python3.4/dist-packages/gns3_server-1.3.0-py3.4.egg/gns3server/modules/iou/iou_vm.py", line 510, in _start_iouyap cwd=self.working_dir) File "/usr/lib/python3.4/asyncio/subprocess.py", line 193, in create_subprocess_exec stderr=stderr, _kwds) File "/usr/lib/python3.4/asyncio/base_events.py", line 652, in subprocess_exec bufsize, _kwargs) File "/usr/lib/python3.4/asyncio/unix_events.py", line 157, in _make_subprocess_transport extra=extra, kwargs) File "/usr/lib/python3.4/asyncio/base_subprocess.py", line 29, in init stderr=stderr, bufsize=bufsize, _kwargs) File "/usr/lib/python3.4/asyncio/unix_events.py", line 491, in _start universal_newlines=False, bufsize=bufsize, _kwargs) File "/usr/lib/python3.4/subprocess.py", line 848, in init** restore_signals, start_new_session) File "/usr/lib/python3.4/subprocess.py", line 1446, in _execute_child raise child_exception_type(errno_num, err_msg) OSError: [Errno 8] Exec format error

I switch back to v1.2.3 and restore project files which were kind of damaged (loss of snapshots).

Looks like we are trying to use a 32-bit version of iouyap on a 64-bit only system (this is usually what Exec format error means). Can you check?

Thanks,

Hello Jeremy,

Actualy i was using iouyap with gns3 v1.2.3 on a 64bits computer, i just upgrade gns3 on the same computer.

Regards.

If you start iouyap from command line it's works?

lvalero commented 9 years ago

Allo Julien,

tu veux dire comme ça : root@gns3lab:/usr/local/bin# ./iouyap -V iouyap version 0.95.0

ou avec d'autres options ?

Merci

Oui

julien-duponchelle commented 9 years ago

Do you have only one version of iouyap in your path?

You can force the iouyap path in ~/.config/GNS3/gns3_server.conf

By adding a section:

[IOU]
iouyap_path = /usr/local/bin/iouyap
iourc_path = /tmp/iourc.txt

when i upgraded to 1.3.0 i am pretty sure i had to put iouyap and licence path back, as they disappeared.

  • i faced the message i sent you trying to start iou devices, i noticed that when i tried to start them a second time they went on, but the lab project was not working (iou routers where linked on a "dump" switch, and there was no connectivity), i also noticed that my snapshots disappeared from the project, and my predefined iou devices and dynamips devices were not present, and so my predefined virtualbox vm.

Regards, Lionel.
