I've adjusted the bug description to match my understanding of the actual problem.
AIUI this does not happen on a disconnected system; if motd.ubuntu.com cannot resolve or returns ECONNREFUSED or EHOSTUNREACH, there should be no 5-second delay. The error only happens on a system which has routes, but has a firewall that drops packets instead of responding to the request. (Or when motd.u.c is actually down.) So, what you appear to be describing here is a deliberate design tradeoff. Unless you are recommending a different timeout (if so, what value?) or asking for this to be disabled altogether (in which case I will refer you to Dustin), I think the only solution here is for your lab to have suitable firewall+proxy settings. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to base-files in Ubuntu. https://bugs.launchpad.net/bugs/1691901 Title: 50-motd-news costs 5 seconds every login on firewalled systems Status in base-files package in Ubuntu: New Bug description: I noticed quite a long time to login to some of my systems via ssh (or scp). Investigating lead me to find out that the '50-motd-news' file (/etc/update-motd.d/50-motd-news) was the primary cost. In line 108 [1] it does something like: curl --connect-timeout "5" --max-time "5" -A "..." -o - https://motd.ubuntu.com The systems I'm seeing this on are in a lab and do not have access to https://motd.ubuntu.com. The way the lab is configured, they just end up timing out. So every scp or ssh connection or other path to trigger update-motd will cost 5 seconds. -- [1] https://git.launchpad.net/~usd-import-team/ubuntu/+source/base-files/tree/update-motd.d/50-motd-news?h=applied/ubuntu/zesty#n108 ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: base-files 9.6ubuntu13 ProcVersionSignature: User Name 4.10.0-21.23-generic 4.10.11 Uname: Linux 4.10.0-21-generic x86_64 ApportVersion: 2.20.4-0ubuntu4 Architecture: amd64 Date: Fri May 19 01:11:30 2017 Ec2AMI: ami-0000004f Ec2AMIManifest: FIXME Ec2AvailabilityZone: nova Ec2InstanceType: m1.small Ec2Kernel: unavailable Ec2Ramdisk: unavailable ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: base-files UpgradeStatus: No upgrade log present (probably fresh install) mtime.conffile..etc.update-motd.d.50-motd-news: 2017-05-19T01:10:25.572110 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/base-files/+bug/1691901/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
