Hi everyone, I'm fairly new to the list.
I've got what I would consider an interesting issue with a little netbook I've been playing around with. basically regular users cannot make any outbound network connections. for example: cpbarnes@netbook:~$ ping 127.0.0.1 socket: Permission denied and cpbarnes@netbook:~$ wget http://127.0.0.1/ Connecting to 127.0.0.1:80... failed: Permission denied. doing the same as root works. Interestingly when i do: root@netbook:~# /sbin/ifconfig i can see the loopback interface AND its ip address 127.0.0.1 however as a regular user i get: "warning: no inet socket available: no such file or directory" i can see the loopback interface but there is no ip address. heres a little background. The netbook features an ARM processor, 128meg RAM, and the main storage is a USB thumb drive wired straight on to the mainboard. It came pre-loaded with Windows CE 6 however, as stunning and feature rich as it was, i got my hands on the vendors linux install for the netbook and installed that. The vendors Linux install is Debian based, ive got 2 varients, Debian 5 and Debian 6. Both present the same problem. I've tried updating the installed packages but the problem persists. The Linux kernel supplied appears to be a customised 2.6 and pretty much all the modules are compiled in. ive done a stack of searching on the interwebs. a lot of people talk about needing to setuid on the ping bin, but this is already done root@netbook:~# ls -l /bin/ping -rwsr-xr-x 1 root root 34984 oct 14 2010 /bin/ping and besides, its not just ping that isnt working. i get this problem with the loopback interface, with the ethernet interface, and with the wireless interface. /sbin/route shows no entries, not even locally connected networks but even after adding one problem persists. e.g. route add -net 127.0.0.0/8 lo some people have also suggested ip tables could be the problem but as far as I can tell no rules are installed. it doesnt even look like iptables support is compiled into the kernel root@netbook:~# /sbin/iptables -L iptables v1.4.8: can't initialize iptables table `filter`: iptables who? (do you need insmod?) Perhaps iptables or your kernel needs to be upgraded. I've never seen a problem like this. Does anyone have any ideas or suggestions on what to look for or what to try next? Thanks or your time. -- Kind Regards, Christopher Barnes e. chris.p.bar...@gmail.com -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
