2014-01-20 10:42:18 -0600 asked a question getting velodyne poll() timeout warning, i can see data but velodyne node can't

I have a HDL-32E sensor and got it working fine on my other PCs., thanks to the velodyne node by Joq.

But on my laptop, I am getting "velodyne poll() timeout" when i try to do 'rosrun velodyne_driver velodyne_node' I am aware of other people getting this error and having them resolved with correct network settings, but none of the solutions i found online worked for me. Another funny thing is I can record the sensor data using vdump, and play it out and even get the pointclouds with no problem, but it just wouldn't work in live setting.

I am using ros hydro on ubuntu raring over chroot (from a chromebook).
I suspect that it might be the chroot that is preventing me from accessing eth0 without root permissions. But them again, I also tried but had no luck even with sudo -s. I was getting traffic over eth0 just fine (checked with bmon), and I noticed I need root permission when I tried to look at the packets using wireshark. This led me to suspect that something needed root permission, but then I was able to use vdump.

I hope this makes sense. This has been driving me nuts! Please help!

Thanks,

slym
