Arm Flint error tftp: client does not accept options when PXE booting - Please Help LAB Configuration Currently my VMs testing is not seeing the menu but is getting the pxelinux.0 file downloaded correctly as you can see on the screen capture and continue with PXE ipv6 instead to provide me with a menu setup on pxelinux.cfg/default.

Follow the below steps to resolve the misconfiguration.

Supports 'tsize', 'blocksize' and 'timeout' TFTP options. Fully compatible with RFC1350, RFC2347, RFC2348 and RFC2349. I have seen this happening in networks where there are multiple DHCPs working. Key features of WinAgents TFTP Client for Windows: Platform: Any 32-bit Windows platform except WinCE. To prevent this, disable TFTP in your network computers. Jun 4 16:28:18 sysman in.tftpd82919: tftp: client does not accept options Make sure the DHCPs option 66 for that subnet is the KACE SDA IP, no its hostname. Indicate that a specific RFC 2347 TFTP option should never be accepted. Therefore it is easy for hackers to spoof your TFTP server and perform malicious actions. This option may not be compiled in, see the output of in.tftpd -V to verify. It does not support authentication or access control and doesn''t have any built-in encryption.

Trivial File Transfer Protocol (TFTP) is a simple File Transfer Protocol which allows file transfer between remote hosts.

This is for non-grub boot loader, especially the boot loader of MS Windows.

In this sanitized version, the server at 172.16.20.170 is the imaging server that DHCP scope option 66 is pointed at. If you need other info from the config, please let me know. I didn't include the ACLs because they're giant and would take forever to sanitize, plus the issue still occurs with all four ACLs off (the inbound and outbound on each vlan interface listed below). Here is the sections of my config that I thought were relevant to the issue. I have removed all the ACLs from the VLANs and tested and the issue still occurs, so it doesn't appear to be ACL related. I've also tried enabling udp broadcast forwarding globally with specific settings on the client VLANs for udp forwarders pointing at the imaging server for ports udp/69 and udp/4011, but this hasn't helped.Īdditionally, while there are both inbound and outbound ACLs applied to both the client and server VLANs, these do not block this kind of traffic for either VLAN. I can see some TFTP traffic coming from the imaging server to the client when I do a packet capture, however, when compared to a packet capture if the client is on the same VLAN as the imaging server there are far fewer TFTP packets, which leads be to believe the boot wim isn't being fully downloaded.

The clients get an IP and start to download the boot wim, but the download doesn't appear to complete. It works fine if the client computer is on the same VLAN as the imaging server, which tells me something isn't crossing the router correctly.ĭHCP scope options 66 and 67 are set pointing at the correct server and the correct boot wim file. We recently changed out our core router from an Enterasys S4 to an Aruba 5412Rzl2 and since then we have been unable to complete a PXE boot into a boot wim file when the client computer is on a different VLAN than the imaging server.
