Install NTP Daemon for Asuswrt Merlin
- ntpd_stats-arm-R3-1.tar.gz (for arm)
- ntpd_stats-mips-R2.tar.gz (for mips)
This package provides a NTP Daemon (ntp-4.2.8p4 for mips and ntpd-4.2.8p9-win for arm) for Asuswrt/Merlin firmwares. Both ARM and MIPS based routers are supported (by installing the correct package). The package tries hard to be firmware version agnostic. Seems that's the case finally.
Entware installed
Step 1: Install rrdtool and wget packages from Entware.
We need rrdtool for graphing. wget is for retrieving the tarball from github.
opkg install rrdtoolopkg install wget
Step 2: Copy /www to /opt/var/www in preparing WebGUI to run from /opt/var/www
tar cf - /www | tar -C /opt/var -xvf -
Step 3: Retrieve and install the package
NOTE We want to install ntpd_stats-arm-R3-1.tar.gz for ARM routers or ntpd_stats-mips-R2.tar.gz for MIPS routers.
WARNING: the tarball has the following content. If you notice a conflict with your setup, make a backup of existing files first. Then do a merge after Step 3 and before proceed to Step 4.
/jffs/bin/ntpd
/jffs/bin/ntpq
/jffs/bin/ntpstats.sh
/jffs/etc/ntp.conf
/jffs/configs/fstab
/opt/etc/init.d/S77ntpd-custom
/opt/var/spool/ntp/Tools_NtpdStats.asp
/opt/var/spool/ntp/stats.rrd
Once safe to proceed, run the following if you have a ARM router
wget --no-check-certificate -O - https://github.com/kvic-z/goodies-asuswrt/blob/master/ntpd_stats-arm-R3-1.tar.gz?raw=true | tar -C / -xzf -
OR run the following if you have a MIPS router
wget --no-check-certificate -O - https://github.com/kvic-z/goodies-asuswrt/blob/master/ntpd_stats-mips-R2.tar.gz?raw=true | tar -C / -xzf -
Step 4: Run the following command to manually start ntpd as litmus test
cp /jffs/configs/fstab /etc; mount -a/opt/etc/init.d/S77ntpd-custom start/jffs/bin/ntpstats.sh
mount -a mounts /opt/var/www to /www. No worries. It's not a destructive operation. The original content of /www still resides safely in ROM.
Stop and check if any error. Or else proceed to next step.
Step 5: (FW version <= 380.67) Patch files for WebUI and restart httpd
cp /opt/var/spool/ntp/Tools_NtpdStats.asp /wwwsed -i 's/Other Settings");/Other Settings", "NTP Daemon");/' /www/state.jssed -i 's/therSettings.asp");/therSettings.asp", "Tools_NtpdStats.asp");/' /www/state.jsservice restart_httpd
Step 5: (FW version >= 380.68) Patch files for WebUI and restart httpd
cp /opt/var/spool/ntp/Tools_NtpdStats.asp /wwwsed -i '/"Tools_OtherSettings.asp", tabName: "Other Settings"/a {url: "Tools_NtpdStats.asp", tabName: "NTP Daemon"},' /www/require/modules/menuTree.jsservice restart_httpd
Stop and check if any error. If things go well, you shall see NTP Daemon on WebUI > Tools page.
Step 6: Create a cron job to collect NTPD stats. Add the following line to /jffs/scripts/services-start
cru a NtpdStats "*/5 * * * * /jffs/bin/ntpstats.sh"
Step 7: Append the following two lines to the end of /jffs/scripts/post-mount
mount -aservice restart_httpd
Step 8: Reboot your router and enjoy!
You may want to reboot now to confirm changes stay.
Check the "server" entries in /jffs/etc/ntp.conf. You may want to replace those ip addresses with time servers near you. Preferrably put some stratum 1 servers there.
You may want to install gpsd from Entware-ng, and get ntpd_SHM.tar.gz from kvic-z/goodies-asuswrt. This tarball contains a version of ntpd which has SHM driver compiled in. Note that this binary is for ARM only at the moment.
For more detail on how to get GPS work, go to this post.
- unstall rddtool and wget through Entware
- remove the lines you added to /jffs/scripts/post-mount and /jffs/scripts/services-start
