[RESOLVED] Delaying timeoute with ping

arx · 2016-09-29 08:37:40

Good evening,

The address I am pinging to is in a private VPN, and I am expecting the ping to fail as I am not connected to the VPN. I want ping not timeout if there is no response and I've manipulated the TTL, timeout, deadline, count, sndbuf and interval flags. All timeoutes are happening at appriximately 10 seconds.

I'm thinking about manipulating the pattern to avoid failed packets.

examples:

$ ping -f -W 60 -w 60 -c 99999 x.x.x.com
ping: unknown host x.x.x.com
$ ^C
$ godmode "ping -f -w 60 x.x.x.com"
ping: unknown host x.x.x.com
$ godmode "ping -f -l 100 x.x.x.com"
ping: unknown host x.x.x.com

Where godmode is a function in .bashrc:

godmode() {
	sudo -i $1
}

Duplicate because it spans system and network: https://bbs.archlinux.org/viewtopic.php … 0#p1657480

Have you experimented with fping which is in extra?

In my opinion, it doesn't fail the ping, but the NS lookup. I think you'll have to specify the IP instead of the hostname.
It would probably best to create your own bash script that loops the commands, maybe with a bit of delay.

Fping did the trick..

here's my alias for anyone that wants it:

function godmode() { sudo -i $1 }
function kvpn() { kill $(ps -ef | grep msjnc | awk '{print $2 " " $3}'); }
alias pbld='godmode "fping -I tun0 <ip address>"'
alias vpn='kvpn; screen -d -m /usr/bin/msjnc --connect; pbld'
