[Buildroot] httpd question

[Buildroot] httpd question

[hartleys]

Hello all,

I enabled the webif package and httpd in buildroot. Everything builds ok
and my system boots. But when I try to access the web interface I get
the following message in my browser:

httpd: bind: Address already in use

If I start the httpd service on a different port (8080) it works fine.

For the life of me I can't figure out what might already be bound to
port 80. Any ideas?

Thanks,
Hartley

try:   nmap -p80 localhost

or instead of localhost the name or ip of your host.

Sounds like you have another process, probably another web server,
listening on that port. Find out which process that is by issuing these
commands:
  # Is port 80 listened at?
  netstat -ln |grep ":80"
  # If so, by whom? (Hopefully your have 'lsof' installed)
  lsof -i :80

[Buildroot] httpd question

[hartleys]

Looks like I do have another process on port 80. Not sure who or how at
this point.

/ # netstat -ln | grep ":80"
tcp  0  0  0.0.0.0:80  0.0.0.0:*  LISTEN

Strange thing is I have a couple ports connected to 0.0.0.0 and in the
LISTEN state. They are 37, 7, 9, 13, 80, 19, and 13.

Right now I don't have 'lsof' installed. I tried enabling it in my
buildroot configuration but can't get the source to download. I keep
getting an "Error in server greeting." message when buildroot tries to
wget the package.

Any other ideas. Either for my problem with port 80 or how to go about
getting the lsof package?

Thanks,
Hartley

I don't think nmap is available as a package in buildroot. At least I
can't locate it.

Ok. Got lsof to download and compile. I had to change the ftp site.

/ # netstat -ln |grep ":80"
tcp        0      0 0.0.0.0:80              0.0.0.0:*
LISTEN
/ # lsof -i :80
COMMAND PID USER   FD   TYPE DEVICE SIZE NODE NAME
inetd   372 root   15u  inet     82       TCP *:www (LISTEN)
/ #

I'm not really sure what this output means. Can you offer any ideas?

Thanks,
Hartley

what scripts are in your /etc/init.d/ directory?
do you have the inetd daemon installed?

[Buildroot] httpd question

[hartleys]

I don't actually have a /etc/init.d/ directory.  There is only one
script (/etc/rc.sysinit) that gets called at boot time.
 
My /etc/inittab starts up the system with a couple mounts and setting up
lo then calling the  rc.sysinit script.
 
# /etc/inittab
# Startup the system
::sysinit:/bin/mount -t proc none /proc
::sysinit:/bin/mount -t usbfs usbfs /proc/bus/usb
::sysinit:/bin/mount -t sysfs none /sys
::sysinit:/bin/mount -t devpts devpts /dev/pts
::sysinit:/sbin/ifconfig lo 127.0.0.1 up
::sysinit:/sbin/route add -net 127.0.0.0 netmask 255.0.0.0 lo
::sysinit:/etc/rc.sysinit
 
*snip*
 
My rc.sysinit sets the PATH, does a couple other mounts, then starts the
following:
 
syslogd -C m 0
klogd
udhcpc -i eth0 -b -p /var/run/edhcpc.eth0.pid >/dev/null 2>&1
inetd
crond
 
A 'ps' shows that initd is running. Also telnet is working fine.
 
This was working fine with busybox-1.1.3. It stopped working when I went
to the latest busybox 1.10.2.
 
Hartley

It means you have an http service configured in /etc/inetd.conf. Post
your inetd.conf to this list if you need assistance.

[Buildroot] httpd question

[hartleys]

I finally got it working.

Had to enable "Support writing pidfiles" in busybox then add the -i
option when starting httpd in inetd.conf.

Then I ran into a problem with awk built into busybox. I was getting a
"can't resolve symbol '__fixdfsi'" error when webif ran some of it's awk
scripts. Using the real gawk package fixed that.

Thanks for all the help,
Hartley

That would be a problem with your toolchain.. either gcc or uClibc, I'm
not sure which... Strange. busybox awk works for me (though I didn't
test the latest).

That's what I figured. Still haven't tried to build a new toolchain.
That step scares me ;-)

Where'd you get your toolchain from? Was it not built by buildroot?
