--- Begin Message ---Package: wpasupplicant Version: 0.7.3-0ubuntu1 Severity: important We just moved from WEP to WPA and started using wpa_supplicant on ~30 Ubuntu 11.04 machines. Almost all machines had trouble connecting as ifup failed when starting wpa_supplicant. The error went something like: cat: /var/run/wpa_supplicant.wlan0.pid: No such file or directory Adding a wait condition in /etc/wpa_supplicant/functions.sh did the trick: --- functions.sh +++ functions.sh.new @@ -281,8 +281,13 @@ if [ -n "$WPA_SUP_OMIT_PIDFILE" ]; then wpa_msg verbose "creating sendsigs omission pidfile: $WPA_SUP_OMIT_PIDFILE" + while [ ! -f "$WPA_SUP_PIDFILE" ]; do + wpa_msg verbose "Waiting for pid file.." + sleep 1; + done; cat "$WPA_SUP_PIDFILE" > "$WPA_SUP_OMIT_PIDFILE" fi + } ##################################################################### This may not be the most elegant way of solving the issue, but it works and the condition is (almost) always met. That is, ifup -v wlan0 prints "Waiting for pid file.."
