@OscarTalks nice catch. I been busy to little time to work, I should have seen it did not show "NO Network". Funny I did test yours and found it did not work for me. That is why I made some changes. And now I also realize I did not say anything. Sorry. I need to be more alert in the future.

For the record grep "state UP" -A2 does work for me.

I am using BusterDog64. Ip Vesion
Code:
root@live:~# ip -V
ip utility, iproute2-ss190107


With network I get
Code:
root@live:~# ip address show | grep "state UP" -A2 | grep inet | echo $?
127


Without Network I get
Code:
root@live:~# ip address show | grep "state UP" -A2 | grep inet | echo $?
0


So after the correction if [ -z "$UpLink" ]; All work fine with me.

Let me see if I had time today for the rotate ovpn script. See I am using you guys jafadmin & OscarTalks as an excuse to learn bash. I do write in C but bash is for the most part new to me. Do not get me wrong I can follow a program. Writing one from of my own is another story. HEHEHEHE

The string "state UP" is present in BionicPup32 so it works.
Unfortunately not so in Stretch and not in Wheezy either.
The executable ip is a symlink to busybox in all cases

Stretch with no VPN
Code:
# ip address show

Thanks, Oscar. I think we can use "MULTICAST,UP" instead. It seems to work on both.

I've changed the script download.

Thanks for the testing. Cool

Subject description: 2 ports for psip?		  
@enrique very nice instructions for puppyphone with IP!!

enrique wrote:
Now you need to know the Port PuppyPhone is using:
Code:
netstat -peanut | grep psip

When I try this I get 2 ports, 5060 and 5061:
Code:
root# netstat -peanut | grep psip
tcp        0      0 0.0.0.0:5060            0.0.0.0:*               LISTEN      0          91578      29175/./psip64

Any idea what this means?
I don't use VPN.

Hi yafadmin

The new netinfo script does not work correctly in stretchdog 32. The old one works correctly. The new scripts produces a No network status while the old script gives me the public ip.

There is some kind of difference in the output of the network tools between various versions of Linux.

either the phrase "MULTICAST,UP" or "state UP" should work for the line:
Code:
UpLink=$(ip address show | grep "state UP" -A2 | grep inet|xargs )
UpLink=$(ip address show | grep "MULTICAST,UP" -A2 | grep inet|xargs )

Just use whichever works with your version.

Naturally, this has not been tested with ALL versions of puppy linux. That level of testing is beyond my time and resources ..

As a report, I did try it on Buterdog64 and bionic32. For mi "MULTICAST,UP" does the job.

gabtech Can you post your result in stretchdog 32 to just
Code:
ip address show

On my Stretchdog 32 system:
With ethernet cable plugged in (same output for both):
Code:

inet 192.168.1.4/24 brd 192.168.1.255 scope global eth0
root@live:~#


With cable unplugged (first command output is empty):
Code:
root@live:~# ip address show | grep "state UP" -A2 | grep inet|xargs

root@live:~# ip address show | grep "MULTICAST,UP" -A2 | grep inet|xargs
inet6 fe80::222:64ff:fe4d:6c17/64 scope link
root@live:~#


EDIT: With cable plugged in, full output of ip address show

Following up on previous post, IMO, the best way (and portable between different OS's) to check for network connection is to use curl "<some common website>" in this case using "https://duckduckgo.com" , then in the script:
Code:
### If "$UpLink" is blank we cannot collect info, so exit ..
#if [ -z "$UpLink" ]; then yad --info --timeout=30 --height=100 --width=100 --center --title="Network Status" --text="$(printf "\n\t   NO Network\n")" &
# exit 0
#fi

# check if there is network connection using curl, replacing the above commented out
 case "$(curl -s --retry-delay 3 --retry 3 --max-time 10 -I https://duckduckgo.com | sed 's/^[^ ]*  *\([0-9]\).*/\1/; 1q')" in
  [23]) echo "OK, there is network connection, continue..." ;;
  *) yad --info --timeout=30 --height=100 --width=100 --center --title="Network Status" --text="$(printf "\n\t   NO Network\n")" &
 exit 0 ;;
 esac

Choice is a fine thing.
Here is a link to a dynamic utility to give an on-screen display.

http://murga-linux.com/puppy/viewtopic.php?p=978652&search_id=2005232242#978652

(Requires basic conky)
EDIT: 4th January 2020 - Please note that it is not suitable for use with Debian Dogs.

I am on BusterDog64 and it has Conky as default. I try to manually install but show nothing. One thing is missing "/root/.config/wallpaper/bg_img" where can I find this?

Edit: After doing conkytogle I have NET:EXT: ***.***.*** over IP(wlan0): ###.###.###. But this value never gets updated if I start VPN or STOP?

What I am doing wrong?

My version, as a way to say thanks. May this be useful for those who need it.

Code:
#!/bin/sh
# Inspiration: http://murga-linux.com/puppy/viewtopic.php?t=117675

TMP=/tmp/ipinfo.$$
cat > $TMP << EOF
Local IP Address(es)
--------------------
$(
ifconfig | sed -n '/^[a-z].*:/ {s/:.*/:/; N; /inet /!d; s/:.*inet /: /; s/[ ]*netmask.*//; H}; ${x;s/^\n//;p}'
)

Remote IP address
-----------------
$(curl -s https://geoip.ubuntu.com/lookup | xml2 | sed 's|/Response/||; s/=/: /')
EOF

[ -z "$DISPLAY" ] && cat "$TMP" ||
Xdialog --fixed-font --title "Network Info" --no-cancel --editbox "$TMP" 0 0 2> /dev/null
rm -f $TMP

For this to work, you need "xml2" which "flattens" XML to a line-oriented format (which then you can process with grep/sed/awk/etc). The original source of this small nifty utility has been blown away by time, but fortunately Debian folks keeps a copy for us.

@jamesbond Your script works very nice. One more sample for my collections.

Now to be honest YOU MADE MY DAY. I like to work in many projects. One of then was in Real Need of your suggested xml2. As this too parse also HTML. So THANK YOU.

Hi enrique,
Sorry my fault, I did not realise that you were using BusterDog64.
The .pet I linked to is only suitable for Pups such as Bionicpup64 8.0
and easyos.
