Wintermute_BBS<p>+++ Sysop News +++ Sysop News +++</p><p>So I'm still investigating the connectivity issues I witnessed with <a href="https://oldbytes.space/tags/rc2014bbs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>rc2014bbs</span></a> and here are my current findings:</p><p>1.) while the telnet listener of the <a href="https://oldbytes.space/tags/Zimodem" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Zimodem</span></a> firmware is no longer open on port 2014, the <a href="https://oldbytes.space/tags/wifi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>wifi</span></a> of the <a href="https://oldbytes.space/tags/esp8266" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>esp8266</span></a> itself is still active and the reserved ip is responding to ping requests.</p><p>2.) once the firmware gets reset via ATZ it sometimes restarts /re-opens the listener on port 2014</p><p>3.) the listener dies a few hours after initial powerup of the system</p><p>4.) my memory may be failing me but those issues began somewhere around autumn last year when I updated the firmware to version 3.7.1</p><p>As a result of these findings, I have reverted the firmware on the esp8266 to Zimodem version 3.6.5. It's not an official release - I checked it out using the corresponding commit hash.</p><p>The BBS was powered up with that version yesterday at 09:00 am and it is still running about 24 hours later, which was never the case with the 3.7.1 version of the firmware. I've also noticed a few other glitches not being present with the 3.6.5 version.</p><p>It is still a little too soon to call the problem solved, but there's movement here. </p><p>Also keep in mind that RC-BOX BBS (the world's first and - currently - only <a href="https://oldbytes.space/tags/rc2014" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>rc2014</span></a> based <a href="https://oldbytes.space/tags/bbs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>bbs</span></a>) is using a wifi connection so other sources of influence may also have an effect on connectivity (although they never were *that* worse before 3.7.1).</p>
