If you are off-net and if the server has a non-routable address that ntp host simply won't be used. -wolfgang -- g+: https://plus.google.com/114566345864337108516/about -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

network-scripts documentation

I'm trying to figure out if I had drop something into /etc/sysconfig/network-scripts/ifcfg-*, that'll have the effect of doing that. if you are using ntpd and not chrony: Yes, I am, but I was not asking how to configure ntp.conf, but how to have dhclient do it for me, with a fake DHCP-provided NTP configuration – similar how to specifying DOMAIN in ifcfg-* sets the domain in /etc/resolv.conf, when the network domain does not come from DHCP. That is, I have an ntp server on my LAN, but the cheap-ass router does not have the option to set the ntp_servers DHCP options, so that the dhclient can do it automatically. Manually setting it in /etc/ntp.conf means that it stays there when the client roams on another network. That's not fatal, nothing bad will probably happen, but it's still wrong. After hacking at it, I finally figured out how to do it, it's not directly supported in ifcfg*, and, of course, none of this appears to be documented anywhere, but it is doable. For the benefit of anyone looking to do the same thing, add the following to /etc/sysconfig/network-scripts/ifcfg-wlan0, or create one if it doesn't exist, with the following: [ -f /etc/sysconfig/network-scripts/dhcp-${CONNECTION_ID// /_} ] \ . /etc/sysconfig/network-scripts/dhcp-${CONNECTION_ID// /_} ] Then, create a dhcp-NAME, where NAME is the same as the ifcfg-NAME for your network, with the following contents: new_ntp_servers=timehost.example.com Or, whatever your LAN NTP server is. This will be sufficient to harass dhclient into doing this automatically, when I'm on my LAN. Fairly certain that this will also work with chrony, and it'll unlikely to get clobbered by minor updates, at least until NetworkManager/sysconfig changes drastically. In case of wired LANs, new_ntp_servers can probably be dropped straight into ifcfg-eth0, but that'll won't work very well when connected to another network, so the right way to do it is by configuring dhcpd, which, unlike the case of a dumb wireless router, is quite doable. pgpRqWTN7K1X9.pgp Description: PGP signature -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Allegedly, on or about 27 January 2013, Sam Varshavchik sent: Google isn't helping me find the documentation for /etc/sysconfig/network-scripts/* in F18.

An alternative approach: Don't use the DHCP server in the router, run one from one of your computers. That's what I do. Is your NTP server a standalone computer? If so, you could run it from there. -- [tim@localhost ~]$ uname -rsvp Linux 3.6.11-5.fc17.x86_64 #1 SMP Tue Jan 8 21:40:51 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
