Dear Team, I am building ziti tunneler sdk c code (v0.17.25) against teltonika provided openwrt SDK. I have used the openwrt build script which is provided in scripts folder.

What specific SDK are you trying to use? zlib is usually built in by default, can you make sure it is included in the Teltonika SDK build? in SDK directory: - `make menuconfig` - select `Libraries`, scroll down to `zlib` - make sure it is enabled and save configuration - build Teltonika SDK ---

Is it possible (I guess an option would likely be in the Teltonika SDK) when one cross compiles it to use the byte order one needs. For example if ziti tunnel sdk expects the byte order to be in the network order, then one can choose that option. The reason, I am asking I cross compiled Ziti version 0.17.32/36 with Teltonika 7.1.4 SDK on ubuntu 20.04 and when I deployed it on the Teltonika Router, the syn packets are dropped at the tun interface. It appears that the byte order is not what expected and the length of the packet is misread. `Lwip - iphdr_len in bytes: 15360` . It should read 60 bytes ---

Odd. Honestly, I would have expected the code to already translate from network byte order to target byte order properly. ---

more context to this issue 1. SDK v6.8.6 has no problem with endiness when complied on ubuntu 20.04 unlike SDK v7.1.4 2. Also, not sure if that matters, but for the SDK 7.1.4 the teltonika switched libs from uclibs to musl. I could not find any confirmation to endiness being switch as well in this upgrade on the Teltonika SDK Side ---

Was able to compile Teltonika v6.9 and ZET v0.17.36, but I found couple of missing include files that needed to add to complete it successfully Steps I did: 1. Used ubuntu 18.04 as host 2.

Follow the procedure to install packages [Legacy RUTOS Software Development Kit instructions - Teltonika Networks Wiki](https://wiki.teltonika-networks.com/view/Legacy_RUTOS_Software_Development_Kit_instructions) 4. select this option `[*] Build the OpenWrt based Toolchain` 5. make -j $nproc 6. git clone [https://github.com/openziti/ziti-tunnel-sdk-c.git;](https://github.com/openziti/ziti-tunnel-sdk-c.git;) cd ziti-tunnel-sdk-c/ 7. git checkout tags/v0.17.36 8. add `#include ` to this file `~/ziti-tunnel-sdk-c/programs/ziti-edge-tunnel/netif_driver/linux/utils.c` 9. add `#include ` to this file `~/ziti-tunnel-sdk-c/programs/ziti-edge-tunnel/netif_driver/linux/utils.h` 10. mkdir build; cd build/ 11. ran this …/scripts/openwrt-build.sh -s ~/RUTX\_R -t mips\_34kc 12. updated this ` DISABLE_LIBSYSTEMD_FEATURE:BOOL=OFF` to `ON` in CMakeCache.txt 13. re-ran this …/scripts/openwrt-build.sh -s ~/RUTX\_R -t mips\_34kc ---

Hi @dariuszSki , I have used [https://wiki.teltonika-networks.com/gpl/RUTX\_R\_GPL\_00.07.02.tar.gz](https://wiki.teltonika-networks.com/gpl/RUTX_R_GPL_00.07.02.tar.gz) (ARM) and [GitHub - openziti/ziti-tunnel-sdk-c](https://github.com/openziti/ziti-tunnel-sdk-c) (v.18.04 tag). I was able to compile it without any issues. I am even able to run ziti-edge-tunnel binary on Teltonika X11 box. But the issue i faced is while it starts up. It couldn’t do the DNS configurations. I will be looking into the code to see how it can be fixed. Also, if team wants to know the error messages, i can put it here or create a new issue for it. Regards, Sameer ---

@sameersarkar-tcl are you able to intercept services? If so, how did you compile it? I am able to compile it for RUT950 router, but when I run the binary on the router, the syn packet is forwarded to the tunnel interface but it is dropped due to the fact that the packet length is misread to be too long. ---

I think the dns issue is related to the fact that ZET is looking for the expected resolvers to be there and they are not present and it fails. If I understand the code correctly, it basically checks what resolvers are available by running commands. Not sure if this can work without the code update, but IP services still should work. Here is the code for DNS resolvers commands I found in the code, when I was looking at this myself file : [ziti-tunnel-sdk-c/tun.c at main · openziti/ziti-tunnel-sdk-c · GitHub](https://github.com/openziti/ziti-tunnel-sdk-c/blob/main/programs/ziti-edge-tunnel/netif_driver/linux/tun.c) ```auto static struct dns_cmd dns_cmds[] = { { .path = "/usr/bin/resolvectl", .update_fn = dns_update_resolvectl, }, { .path = "/usr/bin/systemd-resolve", .update_fn = dns_update_systemd_resolve, }, { .path = "/usr/sbin/resolvconf", .update_fn = dns_update_resolvconf }, {0} }; ``` ---

@dariuszSki , I had to manually update /etc/hosts file, which is a hack which i tried to see if the functionality is working or not. Yes, this is the exact issue we landed up since this code was pushed in. Earlier it was working, say tags/v0.15.36. There was this option of dnsmasq which was available earlier. Now it is discontinued. Now i am looking for those same pieces old code for dnsmasq implementation, place it again and see if it works. Because OpenWRT don’t support resolvectl or systemd-resolve in any way. Regards, Sameer Sarkar ---

Hi Sameer, Can you confirm if the IP intercept is working or not? the IP intercept has nothing to do with resolver. If that does not work, then there is a bigger issue. Thanks, James ---

Hi James, FYI, For the enterprise version we are still using the older versions of ziti-edge-tunnel, even for customer deployments. Using openziti opensource, I didn’t try IP intercept till now. I will do it now. It will be the first time trying with combination of openziti + teltonika box. So before i proceed, please confirm below commands are correct to create a service and bind it. ziti@ziticontroller:/openziti$ ziti edge create config “ipintercept.test.dial” intercept.v1 ‘{“protocols”:[“tcp”],“addresses”:[“100.64.219.150”], “portRanges”:[{“low”:80, “high”:80}]}’ New config ipintercept.test.dial created with id: BHM9o1J.x ziti@ziticontroller:/openziti$ ziti edge create config “ipintercept.test.bind” host.v1 ‘{“protocol”:“tcp”, “address”:“100.64.219.150”,“port”:8000}’ New config ipintercept.test.bind created with id: gJi9o1J.NZ ziti@ziticontroller:/openziti$ ziti edge create service " ipintercept.web.test.service" --configs “ipintercept.test.bind,ipintercept.test.dial” New service ipintercept.web.test.service created with id: wRSWoHk.xZ ziti@ziticontroller:/openziti$ ziti@ziticontroller:/openziti$ ziti edge delete service " ipintercept.web.test.service" delete of service with id wRSWoHk.xZ: OK ziti@ziticontroller:/openziti$ ziti@ziticontroller:/openziti$ ziti@ziticontroller:/openziti$ ziti edge create service “ipintercept.web.test.service” --configs “ipintercept.test.bind,ipintercept.test.dial” New service ipintercept.web.test.service created with id: 07Gzo1JSNZ ziti@ziticontroller:/openziti$ ziti@ziticontroller:/openziti$ ziti edge create service-policy ipintercept.web.test.service.bind.blue Bind --service-roles “@ipintercept.web.test.service” --identity-roles “@ziti-private-blue” New service policy ipintercept.web.test.service.bind.blue created with id: bNTSo1kSN ziti@ziticontroller:/openziti$ ziti edge create service-policy ipintercept.web.test.service.dial.teltonikaX11 Dial --service-roles “@ipintercept.web.test.service” --identity-roles “@TeltonikaX11” New service policy ipintercept.web.test.service.dial.teltonikaX11 created with id: PzhEoHJSNZ ziti@ziticontroller:/openziti$ ziti@ziticontroller:/openziti$ Teltonika box - ziti-edge-tunnel log [540.662] INFO ziti-sdk:ziti.c:1314 ziti\_set\_api\_session() ztx[0] api session set, setting api\_session\_timer to 540s [896.643] INFO tunnel-cbs:ziti\_tunnel\_cbs.c:411 new\_ziti\_intercept() creating intercept for service[ipintercept.web.test.service] with intercept.v1 = {“addresses”:[“100.64.219.150”],“portRanges”:[{“high”:80,“low”:80}],“protocols”:[“tcp”]} [896.643] INFO tunnel-cbs:ziti\_tunnel\_ctrl.c:684 on\_service() starting intercepting for service[ipintercept.web.test.service] [896.643] INFO ziti-edge-tunnel:ziti-edge-tunnel.c:1185 on\_event() =============== service event (added) - ipintercept.web.test.service:07Gzo1JSNZ =============== [924.046] INFO tunnel-cbs:ziti\_tunnel\_cbs.c:428 intercept\_match\_addr() matching 100.64.219.150 Fetching the app in the box. root@Teltonika-RUTX11:~# root@Teltonika-RUTX11:~# curl [http://100.64.219.150](http://100.64.219.150) ``` Hello World ## . ## ## ## == ## ## ## ## ## === /""""""""""""""""\___/ === ~~~{~~ ~~~~~~~ ~~~~~~ ~ / ===- ~~~ \ ______ o _,/ \ \ _,' `'--.._\..--'' ``` root@Teltonika-RUTX11:~# root@Teltonika-RUTX11:~# It seems to be working.

Hi @dariuszSki , For MIPS Teltonika RUT9X (RUTOS) version i was able to build it using below steps; You can see that i am using 7.x Teltonika SDK version and ziti-edge-tunnel (v0.18.4 tag).
