[Nagiosplug-devel] RE: check_http: Socket timeout after 10 second s (but webserver is up! )

[Paul Boot - Bateau Knowledge]

I think you have the same problem as I did. Some embedded HTTP servers in wireless-access points (Sitecom WL-006) and print-servers do not respond to HTTP GET requests sent over multiple TCP packets. (or TCP fragments)

Here is the bug report I just entered:

http://sourceforge.net/tracker/index.php?func=detail&aid=682203&group_id=29880&atid=397597

I have a quick and very dirty work arround.

Kind regards,

PBO.

 Ok, I tried that:
 
 <---cut here---><---cut here---><---cut here---><---cut here---><---cut
 here---><---cut here--->
 spaehfix:/usr/local/nagios # ./libexec/check_http --verbose -H A.B.C.D
 Socket timeout after 10 seconds
 spaehfix:/usr/local/nagios # ./libexec/check_http --verbose -I A.B.C.D
 Socket timeout after 10 seconds
 spaehfix:/usr/local/nagios # ./libexec/check_http --verbose -I
 <FQDN_pointing_to_A.B.C.D>
 Socket timeout after 10 seconds
 spaehfix:/usr/local/nagios # ./libexec/check_http --verbose -H
 <FQDN_pointing_to_A.B.C.D>
 Socket timeout after 10 seconds
 <---cut here---><---cut here---><---cut here---><---cut here---><---cut
 here---><---cut here--->
 
 and again - on the "first Web" on that host, all combinations of IP/FQDN,
 -H/-I is working without giving any problems.
 
 Any further ideas ?
 
 
 Kind Regards,
