Can not ping to the host

Your Linux can`t obtain IP address from DHCP system:

...Sending discover...
No lease, failing

And "Link is Up" -- board`s cable is connected to network, all OK.

Ask your system administrator, if DHCP configured strange. Best way -- Windows and Linux configured through DHCP.

Or try set in Windows option "Default gateway" -- reply to ping go out to this IP, else rejected.

May use "arp -a" in command prompt to display all recently (5 min) dialed IP- and MAC-addresses with your Windows. If see MAC 76:6C:73:63:4B:xx or IP 192.168.2.12, then ping damaged from Windows!

More information, smaller panic findings, please!

And what is output of "arp -a" before and after pinging from board-Linux ? Is appeared new pair IP/MAC in Windows ?

I try repetition of your problem with my SoC and Win7 (or WinXP)-- ping work always from L to W and back. I plug Eth-cable from board to PC port, link is up, remove PC-DHCP, set direct 192.168.132.27/255.255.255.0 to PC and 192.168.132.100 to Linux -- no problem.

Please describe your configuration of net-experiences: hubs, all net devices and it's connections, OS-es, in detail. Include photo of desktop.

Try replace Eth-cable from board, plug it to another jack...

First of all, I would like to thank you for your enthusiasm for helping me!

Here are 2 pictures. One is the result of command arp -a

The other is my OS, device manager.https://www.alteraforum.com/forum/attachment.php?attachmentid=8959 https://www.alteraforum.com/forum/attachment.php?attachmentid=8960

I have reinstalled my Win7, but the problem were not be improved.

Additionally, I can connect to the Internet through this ethernet cable.

And 5 days ago, the Linux target can ping to PC without loss.

May be virus recently infection ? Starting Win in safe mode and network support may disable many viruses once.

"arp -a" say, what packet from Linux (192.168.2.12) received successful.

Win7 may reply to ping to 2nd network 192.168.1.*, if default gateway points there.

Sniff-soft wireshark-win32 may catch and show all Eth packets or with filters.

I not spec in routing tables, this forum about other jungles :)

Pinging from Win7 to Linux add 192.168.2.12 to list of IP/MAC pairs ?

It's possible unplug 2nd net cable, reboot and probe ?

Other PCs present in system ? Pinging there and back is successful ?

qwik,

I changed my PC, then the problem is solved :)
