Sending discover loop
-
Running svn 5417 on Centos 6.7 I’m not able to deploy og register a host. Alle I get on the client is a message saying Sending discover.
The client gets an ip address 192.168.69.x while the server is 192.168.68.254 My dhcp server is not managed by myself, but it has worked with FOG until my FOG server upgrade. The dhcp scoop is 192.168.68.x-192.168.71.x (255.255.252.0).
I did an upload successfully yesterday, but I dont remember which IP address was used then. Could there be some problem when I got an address outside the servers range 192.168.68.x?
Right now I’m stuck with this problem and cannot get FOG to work. -
Subnetting always has some strangeness to it but it shouldn’t be impacting your ability to receive an IP address. That said does the system you have have multiple nics that could receive an IP?
-
My thinkpad clients have two cards, a LAN and a WAN. This has never been problematic before. I have done some more testing and some clients complete a deploy and some fails. All have of course two nics.
-
What is the driver for the WAN?
The kernels are constantly being update and as such they get new drivers fairly frequently. Just because it never happened before does not mean that this cannot happen.
-
@Tom-Elliott The LAN driver is INTEL 82567LM Giganet. WAN driver is Intel WiFi Link 5300 AGN
-
@pmonstad WAN is not Wireless Access network, WAN literally means “Wide area network” which is the premise behind the internet.
Your wireless card should not be impacting this as I do not install any wireless drivers in the kernels.
This does not mean there isn’t a potential for a wireless driver to have slipped in, but I’m not aware of there being one.
Can you boot into a Debug task, and have it wait? The sending discover will end at some point, and it shouldn’t take it too too long. Then we can move along and try to see what the system thinks is available to hopefully figure out a problem.
-
@Tom-Elliott : I am aware of that, I just refer to the Windows drivers installed and showed in control panel. I’m only wire connected when I do upload/deploy. The discover did not end at all. It was unattended from yesterday afternoon and it was still waiting this morning. The strange thing this worked two days ago but stopped working after a svn update. I will try debug mode tomorrow.
-
@pmonstad While i did make changes to the init, I did not make changes to how the network starts.
-
@Tom-Elliott This problem is driving me crazy. A lot of my old client are not able to be deployed any more. I run svn 5469 on a centos 6.7 server. All I get is the message telling Sending discover.
The clients are Thinkpad T500 and R61. Some works, some doesn’t. All have worked in the spring before I “upgraded” to a newer FOG svn.
No changes in my central DHCP server and infrastructure is unchanged.
-
@pmonstad Could you please take a picture of this and post it here?? I just want to make sure FOG can “see” your NIC. We should see this on the picture…
-
The best bet I could give you is to attempt an older kernel. Nothing has changed in how the init handles getting IP Addresses, so if it worked once, it is most likely related to a newer kernel.
-
@Sebastian-Roth I’ll try to make a small movie of the boot tomorrow. The strange thing is, I guess the NIC and drivers are loaded as I could register the host after first removing if from FOG gui. No errors at all during the fog registration…

cdc_etherandwwan0point to a USB mobile broadband network device. Please disconnect this and try again! -
@Sebastian-Roth Thanks! I turned off the Wireless WAN in BIOS and the client works. But this was never a problem before. I do not need this Wireless WAN device, but what if the scenario is different, users have to use the device? Should I then have to turn off/on this device each time I want to deploy the client?
-
From what I could find out on the internet this has nothing to do with wireless!! As Tom already said: WAN means ‘wide area network’ - nothing about wireless! We don’t have any wireless drivers in the kernel (I just checked again). Searching the web about Thinkpad T500 and wwan0 I only see people using USB mobile broadband adapters but nothing about wireless.
Can you please take a picture of the BIOS setting you changed?

Just found this: https://bugzilla.kernel.org/show_bug.cgi?id=13544
the laptop (a thinkpad t500) has an integrated mobile modem. i think it is some kind of ericsson f3507g.
Seams like this is found by the cdc_ether driver. First I thought that some FOG users use the driver with USB network cards. But searching the forum (cdc_ether mentioned only once!) and reading other things like http://www.linux-usb.org/usbnet/ I really wonder if we need this in the kernel. @Tom-Elliott what do you think?
-
@pmonstad Please try updating and running the installer, I’ve updated the kernels to remove the usbnet problem @Sebastian-Roth is describing.
Hopefully this is corrected for now.
-
@Tom-Elliott I ran the installer and rebooted my client. Same problem i.e. it shows same messages during the boot process.
-
@pmonstad The problematic device is shown as wwan0 during client boot, and the device still shows after doing the upgrade to svn 5485.
