Connecting two Puppy laptops by eth0 or wlan0 without router

[gcmartin]

The BENEFIT @Don570 shows is that the SAMBA server ONLY NEEDS TO BE STARTED ON THE DHCP server OR one of your static IP machines. Assuming you are using PUPs or almost EVERY Linux/MAC/Windows they have built-in (OOTB) stuff (clients) to access shared directories.

@Rcrsn51, @JamesBond, @Don570 are all steering you to the same very simple solution with NO changes required on ANY other PC except the one in the picture, below, marked "DHCP Server".

Simple, clean, no questions, little to no debug, no hassles, changes made on ONLY 1 PC.

Can you show the output from each computer for the device in question.

lspci -nnvv | egrep -i "^0|kernel"

[Karl Godt]

To set this thing, on every machine
a) killall wpa_supplicant conf
b) ifconfig wlan0 up
c) iwconfig wlan0 mode ad-hoc
d) iwconfig wlan0 essid "your-essid" # choose your own
e) iwconfig wlan0 channel 2 # choose your own
f) ifconfig wlan0 192.168.1.x # x=1 for machine 1, x=2 for machine 2, etc etc
Good luck.

The ordering of the code seems a little wrong :

Code: Select all

 #!/bin/sh

essid=`dmidecode -t1 | grep -iE 'Manufacturer|Product Name' | awk -F':' '{print $2}'`
essid=`echo $essid`
echo "essid='$essid'"
test "$essid" || essid="localhost-ran-$RANDOM"

ifconfig wlan0 down
iwconfig wlan0 mode ad-hoc
#http://murga-linux.com/puppy/viewtopic.php?p=780052#780052
echo a
pidof wpa_supplicant && killall wpa_supplicant #conf

echo b
ifconfig wlan0 up
echo c
iwconfig wlan0 mode ad-hoc
#c
#Error for wireless request "Set Mode" (8B06) :

#d
echo d
iwconfig wlan0 essid "$essid" # choose your own
echo e
iwconfig wlan0 channel 2          # choose your own
echo f
#ifconfig wlan0 192.168.1.x        # x=1 for machine 1, x=2 for machine 2, etc etc
ifconfig wlan0 192.168.1.1

No Luck until now : ping does not work on / from both machines .

Here found the answer :
http://superuser.com/questions/576661/h ... k-in-linux

you use iwconfig correctly, as you said the problem is that they don't get the same cell ID. On ad-hoc mode, MAC address is assigned as cell ID. You can force wifi devide to use a predefined cell ID by executing sudo iwconfig eth1 ap B6:D6:92:5D:E5:E4 ( e.g., after sudo iwconfig eth1 essid 'my wlan').

Code: Select all

#!/bin/sh

essid=`dmidecode -t1 | grep -iE 'Manufacturer|Product Name' | awk -F':' '{print $2}'`
essid=`echo $essid`
echo "essid='$essid'"

test "$essid" || essid="localhost-ran-$RANDOM"

pidof wpa_supplicant && killall wpa_supplicant #conf

ifconfig wlan0 down
iwconfig wlan0 mode ad-hoc
iwconfig wlan0 ap FF:FF:01:01:F1:F1     #must be the same on both machines

#http://murga-linux.com/puppy/viewtopic.php?p=780052#780052
iwconfig wlan0 essid "$essid" # choose your own
iwconfig wlan0 channel 2          # choose your own

#ifconfig wlan0 192.168.1.x        # x=1 for machine 1, x=2 for machine 2, etc etc
ifconfig wlan0 192.168.2.1 up

iwconfig wlan0
ifconfig wlan0
echo
ifconfig

bash-3.2# ftpget 192.168.2.2 wlan_testfile /root/.xinitrc
bash-3.2# ls
abc dir With SPACE new_file new_file3 wlan_testfile
caller.sh iwlist-HOME-GW310-2014-05-31.txt new_file2 new_file4

The ordering of the code seems a little wrong :

Haha, yeah. It worked on my machines, both of them (very different machines), but apparently the official way to do that is you down wlan0 first, set mode, then up it again before setting essid and channel/freq.
