I think I have it correct because the DHCP server will issue:<o:p></o:p> <o:p> </o:p> dhcpd: DHCPDISCOVER………………………………..<o:p></o:p> dhcpd: DHCPOFFER……………………………………<o:p></o:p> dhcpd: DHCPREQUEST……………………………….. dhcpd: DHCPACK………………………………………..<o:p></o:p> <o:p> </o:p> But then I immediately receive:<o:p></o:p> <o:p> </o:p> in.tftpd[4254]: RRQ from 10.225.248.1 filename pxelinux.0<o:p></o:p> in.tftpd[4254]: tftpd: read: Connection refused<o:p></o:p> <o:p> </o:p> I am not sure if it is a dhcpd.conf configuration problem or not. My switch has “port fast” enabled. I can Kickstart servers with no problem but when I introduce a second subnet into my dhcpd, tftp fails.<o:p></o:p> <o:p> </o:p> How anyone ever seen this?<o:p></o:p> <o:p> </o:p> I had tried this a few months ago but was never able to get around it but I have a need to revisit this now and get it working.<o:p></o:p> <o:p> </o:p> Thanks.<o:p></o:p> <o:p> </o:p> Liz Brosch<o:p></o:p> TSH System Services<o:p></o:p> <st1:place w:st="on"><st1:City w:st="on">Philadelphia</st1:City>, <st1:State w:st="on">PA</st1:State> <st1:PostalCode w:st="on">19104</st1:PostalCode></st1:place><o:p></o:p> office: (215) 823-6144<o:p></o:p> cell: (267) 784-9166<o:p></o:p> <o:p> </o:p></DIV></BODY></HTML>
