I was trying to upgrade from 1.5-rolling-202403010026 to 1.5-rolling-202403180024
and kept all configs . After the rebooting, it seems that the dhcp server was not coming up due to user/group permission.
After the image upgrading:
vyos@vyos:~$ **ps -ef |grep dhcp** _kea 4231 1 0 11:35 ? 00:00:00 /usr/sbin/kea-dhcp-ddns -c /etc/kea/kea-dhcp-ddns.conf root 7050 1 0 11:36 ? 00:00:00 /usr/sbin/dhcp6c -D -k /run/dhcp6c/dhcp6c.pppoe0.sock -c /run/dhcp6c/dhcp6c.pppoe0.conf -p /run/dhcp6c/dhcp6c.pppoe0.pid pppoe0 vyos 9497 7323 0 12:03 pts/0 00:00:00 grep dhcp
the permissions of files and directories under /config :
vyos@vyos:/config$ ls -alt total 244 drwxrwsr-x 2 root vyattacfg 4096 Mar 18 11:35 archive drwxrwsr-x 1 root vyattacfg 4096 Mar 18 11:34 . -rwxrwxr-x 1 root vyattacfg 18957 Mar 18 11:34 config.boot -rwxrwxr-x 1 root vyattacfg 12308 Mar 18 11:34 vyos-migrate.log drwxr-xr-x 1 root root 4096 Mar 18 11:34 .. -rwxrwxr-x 1 root vyattacfg 13425 Mar 18 11:27 config.boot.2024-01-03-055003.pre-migration -rwxrwxr-x 1 root vyattacfg 17000 Mar 18 11:27 config.boot.2024-01-19-081756.pre-migration **-rw-r--r-- 1 arpwatch vyattacfg 221 Mar 18 11:27 dhcpd.leases~** -rwxrwxr-x 1 root vyattacfg 9449 Mar 18 11:27 config.boot.2023-12-07-095931.pre-migration -rwxrwxr-x 1 root vyattacfg 16658 Mar 18 11:27 config.boot.2024-01-16-154157.pre-migration **-rwxr-xr-x 1 arpwatch vyattacfg 103 Mar 18 11:27 dhcp4.leases -rw-r--r-- 1 arpwatch vyattacfg 221 Mar 18 11:27 dhcpd.leases** -rwxrwxr-x 1 root vyattacfg 19732 Mar 18 11:27 config.boot.2024-02-09-032256.pre-migration -rwxrwxr-x 1 root vyattacfg 7410 Mar 18 11:27 config.boot.2023-09-26-143349.pre-migration -rwxrwxr-x 1 root vyattacfg 13446 Mar 18 11:27 config.boot.2024-01-03-210425.pre-migration -rwxrwxr-x 1 root vyattacfg 19832 Mar 18 11:27 config.boot.2024-02-21-150614.pre-migration -rwxrwxr-x 1 root vyattacfg 5952 Mar 18 11:27 config.boot.2023-12-12-002706.pre-migration -rwxrwxr-x 1 root vyattacfg 18957 Mar 18 11:27 config.boot.2024-03-18-033456.pre-migration -rwxrwxr-x 1 root vyattacfg 0 Mar 18 11:27 .vyatta_config **drwxrwxr-x 2 root vyattacfg 4096 Mar 18 11:21 dhcp** drwxrwsr-x 5 root vyattacfg 4096 Feb 19 15:44 container drwxrwsr-x 2 root vyattacfg 4096 Jan 3 17:52 scripts drwxrwsr-x 2 root vyattacfg 4096 Jan 3 17:51 user-data drwxrwsr-x 2 root vyattacfg 4096 Sep 5 2023 auth drwxrwsr-x 2 root vyattacfg 4096 Sep 5 2023 support
and I tried these commands seem to fix it
sudo chown _kea:vyattacfg -R dhcp* restart dhcp server
the kea-dhcp4 is up
vyos@vyos:/config/scripts$ ps -ef |grep dhcp _kea 4231 1 0 11:35 ? 00:00:00 /usr/sbin/kea-dhcp-ddns -c /etc/kea/kea-dhcp-ddns.conf root 7050 1 0 11:36 ? 00:00:00 /usr/sbin/dhcp6c -D -k /run/dhcp6c/dhcp6c.pppoe0.sock -c /run/dhcp6c/dhcp6c.pppoe0.conf -p /run/dhcp6c/dhcp6c.pppoe0.pid pppoe0 **_kea 9831 1 0 12:05 ? 00:00:00 /usr/sbin/kea-dhcp4 -c /run/kea/kea-dhcp4.conf** vyos 10243 7323 0 12:13 pts/0 00:00:00 grep dhcp
It seems that after image upgrading, the user permissions of all directories under /config have changed to root:vyattacfg, but kea-dhcp4 needs permission to access dhcp* related files and directories.
I'm not sure if this is a bug or if it's caused by my improper operation.
Thanks ！
