[Xymon 4.3.7] bad imaps check
list David Agbo
Hi, I have installed Xymon 4.3.7 on Centos 5.8 x64. Before that, I have installed it on a RHEL 5.6, everything worked fine until I tried to check an imaps server. The Xymon on RHEL is OK, and it grab the ssl certificate, but on the Centos, it displays a yellow error, with the message "Service imaps on my_server is not OK : Unexpected service response", and of course don't see the certificate. The only difference (except the system) is that I've compiled a RPM for the Centos system. When I test imaps with openssl on both systems (openssl s_client -connect my_server:993 -ssl3) the result is * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. Could someone tell me what is the problem? Best regards, David AGBO

Can you try testing an https server and see if that behaves the same? I suspect it's not IMAP-related and instead to do with linking against SSL libraries at compile-time. Perhaps run "ldd $XYMONHOME/server/xymonnet" and see if there are difference between the two servers. Cheers Jeremy

Thanks for your answer. You're right, this is not IMAP-related, plus the test of HTTPS returns the following message : Bad Request Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please. Hint: https://my_server Of course, that's what I'm trying... So it can be a problem at compile-time, like I said, the only difference is this RPM. But everything seems to be OK in the SPEC file.

OK, it's really weird...
$XYMONHOME/server/xymonnet returns :
On RHEL :
xymonnet version 4.3.5
SSL library : OpenSSL 0.9.8e-rhel5 01 Jul 2008
LDAP library: OpenLDAP 20343
On Centos x64 :
xymonnet version 4.3.7
LDAP library: OpenLDAP 20343
But in the SPEC file I have :
[...]
%setup
USEXYMONPING=n \
ENABLESSL=y \

Regardless of your spec-file, if you don't have the openssl development package installed, the configure script will disable SSL support. You should see a warning in the xymonnet logfile that SSL tests will not work: "SSL test, but xymonnet was built without SSL support" Regards, Henrik

Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please. Hint: https://my_server Of course, that's what I'm trying... So it can be a problem at compile-time, like I said, the only difference is this RPM. But everything seems to be OK in the SPEC file.

Before that, I have installed it on a RHEL 5.6, everything worked fine until I tried to check an imaps server. The Xymon on RHEL is OK, and it grab the ssl certificate, but on the Centos, it displays a yellow error, with the message "Service imaps on my_server is not OK : Unexpected service response", and of course don't Can you try testing an https server and see if that behaves the same? I suspect it's not IMAP-related and instead to do with linking against SSL libraries at compile-time. Perhaps run "ldd $XYMONHOME/server/xymonnet" and see if there are difference between the two servers.
