NCSA HTTPD and LINUX: Help!!

Post by Steve Pier » Fri, 11 Aug 1995 04:00:00



I am having trouble with NCSA HTTPD and Linux. I am currently running
Linux 1.2.11 and have run NCSA HTTP 1.4.1 and 1.4.2. I am getting SIGSEGVs
after some accesses to my server. I've installed a patch to correct this
but my server still seems to be hosed after some access triggers this
condition. Has anyone seen this?

I  too have encountered this problem.
The server was set to standalone mode.

I still don't know what causes it.
I am currently running it under inetd, and the problem has only surfaced once
in several weeks.

Could you also please forward me the solution /patches for this one?

bye
Rachel

I have a similar problem. One place to look is in the
"Bug Reports" option at http://hoohoo.ncsa.uiuc.edu
(the NCSA documentation). I'm too stoned to cite the details
but there's a thread called "NCSA on Linux goes to sleep"
or something like that. (this is in the new NCSA hyper-news beta
connected to the NCSA docs).

In there it mentions something about this occurring when the
port simply gets overwhelmed with requests (actually it might be
a little different, the msg in the error log cited, and what
I'm experiencing is a "connect failed: conection refused" or
something like that.) at any rate, there was some talk of
increasing the size of the buffer for the queue on the port
that _should_ be a do-able kinda thing seeing as linux comes
bundled with the source. Personally, i wouldn't know where to
begin looking to do that (ask me in a week).

At any rate, has anyone running NCSA httpd linux had problems with
a URL that does _NOT_ end in a backslash gets a 404 whilst
appending it works ok??

i.e http://whatever.com/~foobar = 404 NOT FOUND
    http://whatever.com/~foobar/ = WELCOME TO THE FOOBAR HOME PAGE

P.S. I find running in inetd _helps_ but does not alleviate
the prob. The tradeoff is I can't seem to recover memory or
swap space once it's been used until I reboot.

....does any of this sound halfway coherent????

1. NCSA httpd/Linux 2.0.x and 'httpd:cant resolve symbol recvmsg'

I recently upgraded from Linux kernel 1.2.13 to 2.0.1-19 and also
installed the NCSA httpd 1.5.2 binary from the ftp site. Now, whenever I
set the StartServers to anything besides 0, the following messages
scrolls down the screen as httpd tries to spawn additional servers:
        httpd: can't resolve symbol 'recvmsg'

I also tried compiling 1.5.2 from the source, but got several compile
time errors and have not had the time to look through the code.  I looked
through Boutell's FAQ and the docs at NCSA, but neither gave me any hint
of what could be wrong.

Has anyone else gotten this error or seen the solution in this newsgroup?
Any ideas would be appreciated.
