I can upload files via tftp to this server just fine.
today the search for in.tftpd brought up more then zarro hits in bugzilla: my issue looks very similar to what is described in bug #452678 . Reading there, it was impossible to reproduce on the developer system. Please advise what additional debug information I should gather.
Hi, did you use described configuration with previous release of tftp? If yes, what about previous release of inet? Regards Jiri
I have the same problem with tftp-server-0.49-3.fc11 (i586), even when iptables isn't running. I can see this traces in the system logs: xinetd[10224]: START: tftp2 pid=14580 from=192.168.0.12 in.tftpd[11013]: RRQ from 192.168.0.12 filename hello.txt in.tftpd[11013]: tftpd: read(ack): Connection refused I have checked file permissions, and I can download the file from localhost. In every transaction, I obtain traces like these with tcpdump: 13:10:18.796395 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto UDP (17), length 51) 192.168.0.13.2194 > 192.168.0.11.tftp: [udp sum ok] UDP, length 23 13:10:18.797528 IP (tos 0x0, ttl 64, id 15063, offset 0, flags [none], proto UDP (17), length 72) 192.168.0.11.47378 > 192.168.0.13.2194: [udp sum ok] UDP, length 44 13:10:19.798634 IP (tos 0x0, ttl 64, id 15066, offset 0, flags [none], proto UDP (17), length 72) 192.168.0.11.47378 > 192.168.0.13.2194: [udp sum ok] UDP, length 44 13:10:21.800745 IP (tos 0x0, ttl 64, id 15067, offset 0, flags [none], proto UDP (17), length 72) 192.168.0.11.47378 > 192.168.0.13.2194: [udp sum ok] UDP, length 44 13:10:25.803036 IP (tos 0x0, ttl 64, id 15068, offset 0, flags [none], proto UDP (17), length 72) 192.168.0.11.47378 > 192.168.0.13.2194: [udp sum ok] UDP, length 44 13:10:25.806764 IP (tos 0xc0, ttl 64, id 34948, offset 0, flags [none], proto ICMP (1), length 100) 192.168.0.13 > 192.168.0.11: ICMP 192.168.0.13 udp port 2194 unreachable, length 80 IP (tos 0x0, ttl 64, id 15068, offset 0, flags [none], proto UDP (17), length 72) 192.168.0.11.47378 > 192.168.0.13.2194: UDP, length 44 I hope you can find the problem. Thanks in advance.
Hi, I solved my problem. It was a problem in the configuration of my firewall. TFTP server is running right. Regards.
