I've searched high and low and cannot figure out why I am getting the following error when I try to PXE boot a node: Mar 18 12:49:12 xcat8 in.tftpd[2962]: RRQ from 172.21.4.1 filename xcat/xnba.efi Mar 18 12:49:12 xcat8 in.tftpd[2962]: tftpd: read: Connection refused Mar 18 12:49:16 xcat8 in.tftpd[2963]: RRQ from 172.21.4.1 filename xcat/xnba.efi Mar 18 12:49:16 xcat8 in.tftpd[2963]: Client 172.21.4.1 finished xcat/xnba.efi Any assistance in troubleshooting is appreciated! The xcatprobe check returns good except for DNS (expected, we host DNS off the management node). =================================== SUMMARY ==================================== [MN]: Checking on MN...
