NTP not synchronizing via wireless connection


I have installed Mandriva 2007 on an IBM Thinkpad and am having NTP issues only with the wireless connection.

Upon startup, NTP reports "temporary failure in name resolution" when I use a wireless connection. When using a wired connection, NTP resolves fine.

I have also noticed "link beat lost" and "link beat detected" in the syslog quite often. The wireless interface is an Intel PRO/Wireless 2915ABG, using the ipw2200 driver.

Is it possible to have NTP start up later in the bootup process so that once the network has been up and running for a while, NTP will then synchronize? I've already tried editing rc.local, but ntp continued to start at the same time. I then removed the entry added to rc.local.

I'm almost at the point where it may be necessary to try another distro on the laptop.

FWIW, on this same system, Mandriva would hang during startup AND shutdown/reset at different points in each. Once I turned off the HAL daemon, the hanging stopped. The CPU is an Intel Pentium M at 1.86 GHz with 1.5 Gb of RAM.

I would appreciate any assistance/suggestions in resolving this issue. Thanks.

do you have ntpdate? You might be able to get away with running that later on.

According to syslog, ntpdate runs after the initial failure of name resolution.

I have temporarily installed SuSE on this same laptop and when I changed the network card information to use traditional "ifup" instead of SuSE's Network Manager, ntp will successfully connect and sync.

Does Mandriva have a similar ifup option? I was not able to locate this on my desktop system running Mandriva.

So ntpdate fails as well, or it works?

I don't know about mandriva - I would expect that the tools are there if you want to put something together, but it may not be really supported by the distro.
