[Bug 1448500] Re: tftp-hpa doesn't accept IPv4 connections by default
Thanks for confirming! For the original issue of "Address family not supported by protocol" I am marking this as 'Fix Released'. For the separate issue brought up about not seeing netstat output for IPv4, the following was brought to my attention: '...a process that binds on both by not specifying (or whatever it is it does) ends up in an "netstat --inet6 -nlp" listing but not that "netstat --inet -nlp" one.' As such I do not believe there is an issue here, understandably a user experience one with netstat, but not with tftp-hpa. ** Changed in: tftp-hpa (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448500 Title: tftp-hpa doesn't accept IPv4 connections by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tftp-hpa/+bug/1448500/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1448500] Re: tftp-hpa doesn't accept IPv4 connections by default
The original issue was the following message "in.tftpd[4295]: connect: Address family not supported by protocol". This appears to have been fixed in version 5.2+20150808-1, see Debian bug 793921 (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=793921). This version is found in Xenial (16.04) or later. Due to the fact that this bug was original found with Vivid (15.04) I would ask that it be verified on the supported version found in Xenial and reply if it still occurs. I will move the bug to incomplete until I hear back. The second issue that was brought up in the bug discussion above was due to a change to default configuration. Namely /etc/default/tftpd-hpa was changed to use 'TFTP_ADDRESS="[::]:69"' due to LP: #1228340, which was over 3 years ago. This changed the default behavior in Trusty (14.04) and forward. While I too do not see any IPv4 udp results while running `sudo netstat -lp | grep tftp`, I can confirm that connecting to a server setup with the default configuration using `tftp -4 ` works. I am not sure of the explanation yet, but if this is another issue we should file a different bug and track it. I however, do not believe that tftpd-hpa has been broken for 3 years. This does not appear to affect Debian stable or unstable as the default configuration file in /etc/default/tftpd-hpa for both looks like: TFTP_USERNAME="tftp" TFTP_DIRECTORY="/srv/tftp" TFTP_ADDRESS="0.0.0.0:69" TFTP_OPTIONS="--secure" ** Bug watch added: Debian Bug tracker #793921 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=793921 ** Changed in: tftp-hpa (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448500 Title: tftp-hpa doesn't accept IPv4 connections by default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/tftp-hpa/+bug/1448500/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
