Have to manually restart dhcpcd after suspend

[stardotstar]

Hi all,

When I resume from suspend at the moment I find that my wpa_supp configuration handles the resumption of an association and provisioning of an IP just fine but the nameservices don't work.

I tried down up the interface and same thing, I tried to restart openvpn to see if it was blocking somehow and got the error that openvpn couldn't be stopped;

• which command did you use to suspend?
  
• are you having both dhcpcd and wpa_supplicant in the same runlevel?
  
• delete /var/log/messages
  
• do the s2ram
  
• (wait a minute)
  
• (do what's needed to resume and watch on CTRL+ALT+F12)
  
• wgetpaste /var/log/messages and post the url here

yeah, no, openvpn doesn't seem to want to stop either way. And now I'm not so sure that it's suspend so muich as any kind of acpi event - just came back after it had gone to screensaver/lock and DNS was unresponsive again. same symptoms virtually.

OK wierd - I moved messages to messages.old and did an s2ram waited a few miniutes and she came back - network working and no messages at all - only standard out "

Most system loggers do not reopen their files without good cause. If you move messages to a new name and do not restart the logger, then it keeps writing to that new name. You need to tell it to reopen messages for it to move to the new file.

Please capture, both before and after suspend, the output of ip a ; ip r ; ping -c 1 ip-of-local-router.

OK, resuming this testing now. Thanks for the informations.

I am disabling openvpn.

restarting the messaging system and here is the info requested>

As I am not the expert for openvpn, you might aslo check other sources like

With openvpn on or off?

I've thought this through and I'm trying it with it on.

With openvpn on. And for comparison, you might repeat with openvpn off.

[stardotstar]

This was not productive for some reason

[charles17]

Looks like s2ram doesn't work(?) How then are you getting suspend?

[stardotstar]

Oh, it definitely suspends - both with s2ram and when I close the lid. I can hear the fans go off an everything.

I'll do some more testing now.

The suspend occurred immediately affter the s2ram - resume was normal with networking as I had stopped openvpn

[charles17]

Then it's all ok now? No need to manually restart dhcpcd after suspend?
[SOLVED]?

[stardotstar]

well, the attribution of the problem is incorrect so I guess I could start a different thread - the need to restart dhcpcd after suspend appears to happen only when openvpn is running...
