I am trying to log into my android phone (running sshdroid), using my laptop (ubuntu 12.04). I am on a university sub-network (on wifi), and so is my phone.I tried the following command:ssh root@my_phone_ip -p 2222But the laptop fires back a ssh: connect to host 172.20.27.169 port 2222: No route to hostI cannot even ping to my phone, it gives a destination host unreachable error.I looked for the route information on my laptop which is root@abadmin-Vostro-3500:~# routeKernel IP routing tableDestination     Gateway         Genmask         Flags Metric Ref    Use Ifacedefault         eduspot-berlioz 0.0.0.0         UG    0      0        0 wlan0link-local      *               255.255.0.0     U     1000   0        0 wlan0172.16.185.0    *               255.255.255.0   U     0      0        0 vmnet1172.20.0.0      *               255.255.0.0     U     2      0        0 wlan0192.168.248.0   *               255.255.255.0   U     0      0        0 vmnet8To check what packets were going through I have tried a tcpdump -i wlan0, but I could not find any interesting packets.
