dhcp issue - Lenovo E73 - Realtek RTL8111GN
-
This is the Nic port specs of E73 desktop. “Ethernet : Gigabit ethernet port, Realtek RTL8111GN, Wake on LAN
”
does that help in finding solution to this issue ? -
@Sebastian-Roth switch is not the issue.i tried all different switches, network cables even tried 3 more E73’s but still same issue. than i tried E72 model which is one generation older than this and that one worked. so its model specific issue.i just posted NIC description of E73 in earlier post. please check to see if there is any issue with that.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1007236So you are right. It seams model specific. Not sure when I will find the time to build a kernel with a modified driver version. Not sure if we want to maintain a different driver version anyway.

Not sure why same E73 works in another FOG server which is in our network.The only difference is that DHCP is handled by our own DHCP server.the process of NIC going down and coming back up is same across all computers. I have feeling some service in FOG not working as it should in this isolated setup. just not able to point which one it is. if you guys think this isn’t FOG issue. feel free to resolve this post.
Thank you all for quick responses.Appreciate all help.

@pdit Well, not knowing your setup in all details makes it hard to guess about the reasons.
Do you have different versions of FOG running on those two different servers?
-
Our working FOG server is 1.5.4 version. isolated FOG server is 1.5.6 (one in question)
Here is Details about working FOG
Hardware : Lenovo M91p desktop
Running as VM in Vmware ESXi version:6.7.0
Desktop is connected to Linksys switch ( i sent you link about it earlier) which is than connects to Netgear managed switch.
DHCP is handled by MS windows server. Gateway is sophos firewall where options 66 & 67 are also setup.we usually connect computers directly to Linksys switch where fog is connected and get them imaged.this is fastest way as transfer rate is much higher. sometimes we image them at some random location. but in both situation we have no issue imaging any type of computer. we maintain standard here so all our computers are of Lenovo brand. models are different and they changes every year. E73’s are the most in use here across offices.
The reason why we are setting up isolated FOG is to send it to our remote offices and get their computers imaged to win10. we tried doing this over WAN but failed. option 66 and 67 was setup correctly at one office but when computer boots up it doesn’t talk to FOG server which is here in our main office even though we have VPN tunnels in place.
Hope this helps. let me know if you need additional info.

i have setup new fog server identical to the one that is working with same hardware. everything is same except FOG version.and it still not working with E73 desktops. it is now proven that issue is not with E73 NIC but it’s FOG problem.
FOG Team, how can i get version 1.5.4 ? i am certain that this version of fog won’t give me trouble. Please help me get it.
-
@pdit I’m still not convinced its a fog issue here, but to answer your request you can get the 1.5.4 tarball here: https://github.com/FOGProject/fogproject/archive/1.5.4.tar.gz
-
I can confirm that the issue was in new FOG version. after i installed 1.5.4 version i am able to image same E73 desktops which didn’t work in new version. FOG team should look at what’s wrong in new version.
Thank you all for help. Please mark this resolve.

@pdit So it’s probably something that changed in the Linux kernel that is causing this issue. I’d like to track this down but I don’t think I’ll find the time to do so in the next months.
You should be able to switch between different kernels to see which version first had the issue. Find all the different kernel versions in the FOG web UI or here: https://fogproject.org/kernels/
