addr_gen_mode no such file or directory #47

Closed RalphCodesTheInternet closed 1 year ago

Currently when starting the access point, I get the following output.

linux-router 0.6.6 (https://github.com/garywill/linux-router) Released under LGPL, with no warranty. Use on your own risk.

PID: 4714 Target interface is wlan0 (30:d8:c4:52:d8:91) cp: cannot stat '/proc/sys/net/ipv6/conf/wlan0/addr_gen_mode': No such file or directory Error occured

ERROR: Failed backing up interface ipv6 bits

Doing cleanup.. Undoing iptables changes .. Exiting: This is the only running instance Cleaning up done

Before this was working on Ubuntu 22, but now I have downgraded to 20.04 and receiving this issue. Any tips?

Try delete

https://github.com/garywill/linux-router/blob/a414ac035b3bc8edbdac594fc49f5eed185a2f70/lnxrouter#L1086 https://github.com/garywill/linux-router/blob/a414ac035b3bc8edbdac594fc49f5eed185a2f70/lnxrouter#L1099

And check does /proc/sys/net/ipv6/conf/wlan0/addr_gen_mode exist? What's its permission and owner?

RalphCodesTheInternet commented 1 year ago

I can confirm /proc/sys/net/ipv6/conf/wlan0/addr_gen_mode does not exist.

I have tried Ubuntu desktop as well as server, with the same issue. I could try using Ubuntu 18 and see if it works better?

If commenting out those two lines, other errors appear, such as

cp: target '/proc/sys/net/ipv6/conf/wlan0/use_tempaddr' is not a directory ./lnxrouter: line 1087: /dev/shm/lnxrouter_tmp/lnxrouter.wlan0.conf.2L0RT0/sys_6_conf_iface/: Is a directory Error occured

ERROR: Failed backing up interface ipv6 bits

Strange that this happens on Ubuntu 20. Ive used this script on Ubuntu 22, Armbian and Raspbian operating systems without any problems.

Don't comment the two lines. Delete them. That's different. (because new line sign used)

What seemed to work was using another kernel version of Ubuntu. I was using 4.9. When upgrading to Focal with kernel 5.13, it works perfectly. Can confirm that it works on Ubuntu Jammy with kernel 5.16 as well. So i guess the problem was related to the older version of the Linux kernel.

So for anyone having the same issue, I guess upgrading to anything 5+ should do the trick.

Thanks for the help in any case @garywill it is much appreciated.

According to https://docs.openstack.org/neutron/latest/admin/config-ipv6.html "Support for addr_gen_mode was added in kernel version 4.11."
