HiI want to run a cron job in /etc/crontab that runs (ifconfig em0 down; ifconfig em0 up) if my cables static ip gateway can't be pinged but I can't figure it out. I can't get the syntax that runs in the command window, to then put intot the crontab.... Can anyone help me? I've tried all sorts such as: if (ping -c1 a.b.c.1 != 1) then ifconfig em0 down; ifconfig em0 up endif if ping -c1 a.b.c.1 != 1 then ping -c1 203.97.234.1 endif if ping -c1 a.b.c.1 (ifconfig em0 down; ifconfig em0 up) if ( ping -c1 a.b.c.1 != 1) ( ping -c1 203.97.234.182 ) if $command("=ping -c1 a.b.c.1 =0") echo sucess if ping -c 1 -w 1 a.b.c.1 >/dev/null echo sucess if [[ (ping -q -c 3 a.b.c.1) == @(*100% packet loss*) ]]; echo sucess if ! ping -c a.b.c.1 > /dev/null ; then echo sucess ; echo fail; fi Any help would be appreciated. Kind regardsDavid Hingston
I would recommend you make a shell script, place it in /root/bin or something else sensible, and have cron call that. I think it's generally frowned upon to have excessive scripting directly in the crontab. The following script should do what you want:
#!/bin/sh if ! ping -c1 203.97.234.1821>/dev/null 2>/dev/null then ifconfig em0 down && ifconfig em0 up fi _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
