Ive followed the recent "recipe" for setting up G2-Link on an Almalinux G3 system. It seems to be almost working, in that I can connect to an XLX reflector but after about a minute it unlinks automatically. Timeout is currently set to 10 minutes (was previously no timeout), but either way, this what I see in the G2-link.log Any clues as to where I should go next? 120924 at 16:44:59:sending link request from mod B to link with: [XLX252 ] mod A [45.77.227.69] 120924 at 16:44:59:Connected from: XLX252 120924 at 16:45:02:sending File:[/root/g2_link/linked.dat], mod:[B], RADIO_ID=[LINKED XLX252 A ] 120924 at 16:45:03:finished sending File to mod:[B] 120924 at 16:45:50:Unlinked from [XLX252 ] mod A, TIMEOUT... 120924 at 16:45:53:sending File:[/root/g2_link/unlinked.dat], mod:[B], RADIO_ID=[UNLINKED TIMEOUT ] 120924 at 16:45:54:finished sending File to mod:[B]

Good Morning All, I’ve recently set up a new Repeater and gateway for Houston, Texas (N5BDJ) on Icom G3 repeater. The gateway is running on AlmaLinux with G3, and I’d like to explore using G2-Link to have new dashboard/Dplus and more important functionality and connect to XLX250. Additionally, we have another repeater running C4FM that I’d like to link to XLX250 through this setup. Could you please provide the necessary files and steps for installation of the G2-Link? Thank you in advance for your assistance! 73 Fred Joly

We have had G2_link and Dplus running on K2BWK for several years. Something that has been bugging me is that Links don't show up on the G2 page but do on the DPlus page. Is that the way it is supposed to be or do I have something configured wrong. 73 Steve KD2OM Admin K2BWK

Hi g2_link admins, As you have seen by some recent posts of mine, I have been working on getting g2_link working alongside of the new dplus G3 version 3.2 on an AlmaLinux install. I think I worked out all the kinks and I documented the install by creating the attached "recipe". These instructions should work for other admins as well assuming they have a working dplus G3 version 3.2 system running on AlmaLinux. Please note: My attached instructions does not document the multiple options for dashboards, it just documents what I used on VY1RDS. I do not used the supplied "my_scripts" or "cron" that was on va3uv's website, I used slightly modified versions as described in the next bullet point. For the specific bits that are different than previous installs (some described below), I created a new tar file and place it on my website for download. This is included in the attached documentation. These files include: modified crontab entries, disabled by default except the update_gwys one. systemd services for use in AlmaLinux slightly modified "my_scripts", and additional specific scripts I created for email notifications when new users register (work in progress, but mostly works), as well as a backup script that backups up g2_link config, dplus, and ircddb3 (if installed) some customizations used on the vy1rds dashboard patch file for g2_lh, to stop it from crashing (as per my last email, I still need to investigate why the condition comes up that was causing it to crash to begin with) Please feel free to pick my work apart, reuse any or all of it, and/or re-incorporate any bits and pieces of this recipe or my tar file in official documentation for g2_link (assuming it actually works on other gateway installs--it should). I will be following this recipe on a backup gateway I will be building shortly, so if I notice any errors at that time I will update and resend. Feedback welcome. Enjoy, Rob, VY1RDS

While messaging with another D-STAR admin, about the coexistence of dplus and g2_link and how it used to be with a single command structure. Oh well. It did give me an idea.... dplus supports using 0-9 and A-Z in the 7th position and X in the 8th spot to execute a shell script. So maybe we can make it easier for users to use dplus to change to an XRF/DCS reflector? I created a test script, exec-U.sh in the /dstar/scripts directory, made it executable with the chmod +x command: =========================== #!/bin/bash # script to automatically connect # A port connect to DCS351D using the g2_link tool # disconnect first /usr/bin/nc -u -w 1 10.0.0.2 30003 <<EOF um A EOF # sleep 3 # disconnect dplus echo " U" >/dstar/tmp/link-a # sleep 3 # first connect with netcat to port # then connect to DCS351D /usr/bin/nc -u -w 1 10.0.0.2 30003 <<EOF lm ADCS351D EOF exit 0 ===================== I then added a new entry in to the DV memory of my ID-51A with a NAME of whatever you want and then the CALL SIGN:______UX (6 spaces, the U and then an X) Transmitted to the repeater: ==> dplus.log <== User update (KA8SCP ) rpt (WB1GOF C) 2022/09/22 12:51:16.303 Remote client forward start streamid 3932 2022/09/22 12:51:16.312 rpt2 (WB1GOF G) rpt1 (WB1GOF C) urcall ( UX) mycall (KA8SCP /ID51) Exec start streamid 3932 2022/09/22 12:51:16.312 rpt2 (WB1GOF G) rpt1 (WB1GOF C) urcall ( UX) mycall (KA8SCP /ID51) user message (Terry - Westford MA ) mycall (KA8SCP ) streamid 3932 Stream end streamid 3932 cnt 45 missed 0 elapsed 00:01 2022/09/22 12:51:17.165 exec file /dstar/scripts/exec-U.sh submitted ==> g2_link.log <== 092222 at 12:51:17:Received command [um A] from [10.0.0.2] 092222 at 12:51:17:cmd=[um], parameter=[A] 092222 at 12:51:17:Unlinking from [DCS351 ] mod D 092222 at 12:51:20:sending File:[/root/g2_link/unlinked.dat], mod:[A], RADIO_ID=[UNLINKED ] ==> dplus.log <== Reading link file /dstar/tmp/link-a for 'A' streamid 2e4d 2022/09/22 12:51:20.464 Reflector/Gateway unlink request streamid 2e4d 2022/09/22 12:51:20.464 rpt2 (WB1GOF G) rpt1 (WB1GOF A) urcall ( U) mycall (WB1GOF / ) playfile /dstar/dv/alreadyunlinked.dvtool to A Adding message >Not Linked < to /dstar/tmp/play-a.dvmsg playfile mod 0 tvs/u 1663865481/465050 tvps/u 0/699660 timediff 1713137214 Reading file /dstar/tmp/play-a.dvtool to 'A' streamid 2b71 2022/09/22 12:51:21.465 Read msg file for playback rpt2 (WB1GOF A) rpt1 (WB1GOF G) urcall (CQCQCQ ) mycall (WB1GOF /RPTR) Finished reading file /dstar/tmp/play-a.dvtool to 'A' streamid 2b71 2022/09/22 12:51:21.465 Play file recall to module A stream 2b71 ==> g2_link.log <== 092222 at 12:51:21:finished sending File to mod:[A] 092222 at 12:51:23:Received command [lm ADCS351D] from [10.0.0.2] 092222 at 12:51:23:cmd=[lm], parameter=[ADCS351D] 092222 at 12:51:23:sending link request from mod A to link with: [DCS351 ] mod D [45.33.127.97] ==> dplus.log <== OK ==> g2_link.log <== 092222 at 12:51:23:Connected from: DCS351 092222 at 12:51:26:sending File:[/root/g2_link/linked.dat], mod:[A], RADIO_ID=[LINKED DCS351 D ] 092222 at 12:51:27:finished sending File to mod:[A] ================================================ Still working on trying to figure out why an XLX reflector request times out. -- Terry Stader - KA8SCP D-STAR Gateway & Reflector Admin

Hi There, I haven't seen too much out there about people successfully installing g2_link alongside a new AlmaLinux install, but I wanted to share that I successfully upgraded our local repeater (VY1RDS) this evening to AlmaLinux, the latest iCom gateway/dplus software, ircddb addon--and, just now, I had a working g2_link manually running with it as well I verified quickly by linking/unlinking to XRF reflectors, and verified I was getting though to the reflector. I used the same binary package that I was using on CentOS. Over the next week, I plan to convert the services from the old format to systemd, and make things automatic (again, I was just running the g2_link manually this evening with a few script modifications) as well as make sure I can get the FreeStar dashboard up and running, etc. I hope to have this all done before mid-September, but if I do not get around to it (that day job of mine and kids sure do take up a lot of my time), I will put this work on pause until early October as I am away the last two weeks of September with no communications. Before I work on converting the services over / documenting everything that I did to get g2_link working (which didn't involve too much modification) I wanted to verify that no one else has already done / shared this? Based on my preliminary searching, I have not found anything along these lines. Rob, VY1RG

So ... VA3UV. Has he given up the G2_link project? If yes, then where does that leave us? I do note that it's G2_link and not G3_link, so if the "G" relates to the Icom bits, now G3.2, does this mean it's pretty old? I don't have the software (I know - I haven't asked The Right Guy - it's fine) so don't know what it consists of. If it's scripts, we can probably make do. If it's binaries and we have no source ...

Good day everyone. With the release of G3.2 supporting Alma 9 as Icom moves away from the EOL of Centos 7, it looks like we need to address the future of g2_link. I am not a “coder”. I can look at code and read it well enough, but I do not know where to begin in a migration from Centos 7 to Alma 9 and g2_link. Is there anyone in the group that has some knowledge in this vein? Or even knows someone who would take a look at the task? Any thoughts? Terry KA8SCP -- Terry Stader - KA8SCP D-STAR Gateway & Reflector Admin

Did anyone come up with a AlmaLinux version of the init.d “service” file for g2_link? Terry -- Terry Stader - KA8SCP D-STAR Gateway & Reflector Admin

From Tomek SQ5DCP: I made some small changes to my installation. 295 instruction line: #/root/g2_link/g2_lh -m "B" -o /var/www/html/fs.html -b "$GW_CALL D-STAR" -r -t /root/g2_link/g2_lh.tpl $GW_CALL I removed the word "D-STAR" because it caused the table to expand beyond 700px. #/root/g2_link/g2_lh -m "B" -o /var/www/html/fs.html -b "$GW_CALL" -r -t /root/g2_link/g2_lh.tpl $GW_CALL I also made my own multidash.html file instead of sidebyside.html (attached). Thanks to this, the tables are displayed next to each other on a wide screen, and below each other on a narrow screen (mobile device). Use it if you like it. ;-) -- Terry Stader - KA8SCP D-STAR Gateway & Reflector Admin

Hi, I'm with a D-STAR user group which has a long standing Icom repeater stack with G3 gateway. As this is an important site for USTRUST registrations, we want to keep our G3 gateway intact, but add connectivity to XRF and DCS reflectors, as I run an XLX reflector that our user base is unable to access (I also run a dplus reflector which is heavily used by the system). As I am more familiar with the open source systems (ircDDB, xlxd, etc), I'm doing the research for adding the capabilities to access these systems to the gateway, and am working with the repeater admin who does the hands on work with the system. I found out about g2_link by asking around the OpenDV group, and got led here. g2_link looks like one of the pieces we need to upgrade the system, and I would like to get it installed on our system. What do I (or more correctly, what does our admin) need to do to get g2_link running on our system?

While installing g_link on W4THM, ran in to a situation where that system used an IP other than the “default” 10.0.0.2 gateway assignment. The issue was in the dashboard fs.html generation, the cron command to create and update the g2_link dashboard failed, the command timed out. Sure enough, the g2_lh has some “switches” you can use… one was a “-a” which allowed an IP to be defined. So I inserted a “-a 192.168.1.172” in front of the -m and saved it… the dashboard was created and now updates just fine.

The SSL certificate that Robin AA4RC provides for those gateways that use the MYCALL.dstargateway.org domain... attached are two ways to update it.

What is needed to download and get installation instructions for the G2-Link software?

Only a portion of groups.io subscribers are getting the verification email. If you didn't receive one, then you don't need to do anything. This link has more information about the groups.io re-verification process: https://groups.io/static/reverifyfaq If you have received the re-verification, then you need to follow the instructions in the email. Another one will be sent out on 1/28/2024 if you deleted the first notices. If you log into your groups. io account (link is below) on the website, this will count as verification. (See above FAQ link) Sorry about the inconvenience. This is a groups.io action and we just got notified about it recently in an email to list administrators. -- Terry Stader - KA8SCP D-STAR Gateway & Reflector Admin

Over the last few weeks, you may have gotten an email asking you to re-verify your subscription to this or other groups.io lists. This is a legit email and if you want to remain active, you should verify it is really you and not a bogus account. This is Groups.io’s way at taking out SPAM.
