Sorry, Karl, you're absolutely right. I sink on my knees and apologize

monitor1-lx:~ # /usr/local/nagios/libexec/check_http -V
check_http (nagios-plugins 1.3.0) 1.24

It just timeouts ...

Yes I did:
monitor1-lx:~ # /usr/local/nagios/libexec/check_http -H 10.35.178.154 -p
80 --verbose
Socket timeout after 10 seconds
That's the result I receive with or without the --verbose option ...

Yes. It works with port 80:
monitor1-lx:~ # telnet 10.35.178.154 80
Trying 10.35.178.154...
Connected to 10.35.178.154.
Escape character is '^]'.
GET
HTTP/1.1 405 Method Not Allowed
Content-Type:text/html
<HTML><HEAD><TITLE>Remote Insight</TITLE></HEAD><BODY>
<H1>Request Error</H1>
HTTP/1.1 405 Method Not Allowed
</BODY></HTML>
Connection closed by foreign host.
But not with 443:
monitor1-lx:~ # telnet 10.35.178.154 443
Trying 10.35.178.154...
Connected to 10.35.178.154.
Escape character is '^]'.
GET
I also tried it with 'strace':
monitor1-lx:~ # strace /usr/local/nagios/libexec/check_http -H
10.35.178.154 -p 80 --verbose
The final output
...
connect(3, {sin_family=AF_INET, sin_port=htons(80),
sin_addr=inet_addr("10.35.178.154")}}, 16) = 0
send(3, "GET / HTTP/1.0\r\nHost: 10.35.178."..., 91, 0) = 91
recv(3, "HTTP/1.1 200 Ok", 1023, 0) = 15
recv(3, "\r\nContent-Type: text/html\r\n", 1023, 0) = 27
recv(3, "Expires: Fri, 30 Oct 1998 14:19:"..., 1023, 0) = 38
recv(3, "\r\nCache-Control: no-cache\r\nConne"..., 1023, 0) = 44
recv(3, "\r\nTransfer-Encoding: chunked\r\n\r\n", 1023, 0) = 32
recv(3, "514", 1023, 0) = 3
recv(3, "\r\n<!DOCTYPE HTML PUBLIC \"-//W3C/"..., 1023, 0) = 536
brk(0x8052000) = 0x8052000
recv(3, " licensed to the U.S. Government"..., 1023, 0) = 1023
brk(0x8053000) = 0x8053000
recv(3, " server is not configured to use"..., 1023, 0) = 49
brk(0x8054000) = 0x8054000
recv(3, "ou will not be able \r\nto communi"..., 1023, 0) = 168
recv(3, 0x804f440, 1023, 0) = ? ERESTARTSYS (To be restarted)
--- SIGALRM (Alarm clock) ---
fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 0), ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0x40016000
write(1, "Socket timeout after 10 seconds\n", 32Socket timeout after 10
seconds
) = 32
munmap(0x40016000, 4096) = 0
_exit(2) = ?
It stops until it receives a SIGALRM ... (from whome? - The embedded
webserver? - Thats the part I do not understand)
In addition: We use iLO Firmware 1.26
Can I provide you more information to find a solution for this?
Regards,
Jens
