Whoops ! Failed to load current Xymon status, (Cannot resolve hostname)
RESOLVED: After all that cleanup in the prior email, I went down a level to /etc and did the same grep. I found /etc/defaults/xymon-client and it had reference to 10.118.15.13 - I removed that and now things are working perfectly.

Here's a bit more info. In the original email, I quoted a part of the log that indicated that communication was blocked to 127.0.0.1 and 10.118.15.13. 127.0.0.1 is obviously localhost and that makes sense. 10.118.15.13 is one of the test hosts that I was monitoring. There should be no attempts to communicate with that host over port 1984 but, it seems like that is what is failing. So, I removed all reference to 10.118.15.13 from all the cfg files. Then I went to /usr/lib/xymon and did "grep -R 10.118.15.13 *" and didn't find anything. Well, originally I did find references in log directories and tmp directories that I cleaned out. With the xymon daemon stopped (service xymon stop), I ran that grep again and got nothing. Then, I started the xymon daemon up, did the grep and immediately there were references to 10.118.15.13. Where else could xymon be picking up this IP address? this is the result of "grep -R 10.118.15.13 from /var/lib/xymon": client/logs/xymonclient.log:2024-06-11 18:20:51.742811 -> Recipient '127.0.0.1, 10.118.15.13', timeout 15 client/logs/rrd-status.log:2024-06-11 18:20:53.518567 -> Recipient '127.0.0.1, 10.118.15.13', timeout 15 client/logs/alert.log:2024-06-11 18:20:53.518402 -> Recipient '127.0.0.1, 10.118.15.13', timeout 15 client/logs/rrd-data.log:2024-06-11 18:20:53.526419 -> Recipient '127.0.0.1, 10.118.15.13', timeout 15 client/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/0 Jun 11 14:43 (10.118.15.13) client/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/1 Jun 11 14:43 (10.118.15.13) client/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/2 Jun 11 14:44 (10.118.15.13) client/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/3 Jun 11 14:44 (10.118.15.13) client/tmp/msg.ma-mrtgmon.txt.14273:tcp 0 1 10.100.10.219:46176 10.118.15.13:1984 SYN_SENT client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61061 SYN_RECV client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:22 10.118.15.13:42294 ESTABLISHED client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:22 10.118.15.13:42238 ESTABLISHED client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:60972 TIME_WAIT client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61034 TIME_WAIT client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61033 TIME_WAIT client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61035 FIN_WAIT2 client/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:60971 TIME_WAIT server/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/0 Jun 11 14:43 (10.118.15.13) server/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/1 Jun 11 14:43 (10.118.15.13) server/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/2 Jun 11 14:44 (10.118.15.13) server/tmp/msg.ma-mrtgmon.txt.14273:monitor pts/3 Jun 11 14:44 (10.118.15.13) server/tmp/msg.ma-mrtgmon.txt.14273:tcp 0 1 10.100.10.219:46176 10.118.15.13:1984 SYN_SENT server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61061 SYN_RECV server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:22 10.118.15.13:42294 ESTABLISHED server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:22 10.118.15.13:42238 ESTABLISHED server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:60972 TIME_WAIT server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61034 TIME_WAIT server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61033 TIME_WAIT server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:61035 FIN_WAIT2 server/tmp/msg.ma-mrtgmon.txt.14273:tcp6 0 0 10.100.10.219:80 <http://10.100.10.219/>; 10.118.15.13:60971 TIME_WAIT root at ma-mrtgmon:/usr/lib/xymon# On Tue, Jun 11, 2024 at 11:11?AM Jerry Shenk <user-5c36d8269320@xymon.invalid> wrote:yes, it's a new installation and that is exactly what it sounds like. The error says "Cannot determine IP address of message recipient (127.0.0.1)". How can that be?....that's the localhost and, that's the only xymon computer. I can ping 127.0.0.1 and connect to port 1984 and, I can even connect using bb and pull hostinfo (/usr/lib/xymon/server/bb --debug 10.100.10.219 hostinfo). That command also works using 127.0.0.1 and ma-mrtgmon (the name of the xymon server).
