Re: [squid-users] is anyone listening to my queries summary o f events

Hi all
sorry for disturbing u all once more but there r certain doubts which
need to be put at rest

1> getting the "Resource Temporarily unavailable" message is NoRMAL as
per Henrick
   " You only get this message because you have enabled more detailed
debugging.
The message is expected, and is printed at debug level 2."

2> as per adrian's and robert's suggestions i did install squid2.4S1 on
a plain vanilla redhat6.2(zoot) kernel 2.2.14-5.0
  compile optyions
--enable-snmp, --enable-storeio=ufs,diskd
 this particular machine is not directy connected to the internet so i
used a parent proxy using the foll config
both are 2.4S1

cache_peer 10.1.11.18 parent 3128 0 no-query default
never-redirect allow all
child ip = 10.1.11.225
parent ip 10.1.11.18

browser used child proxy as its proxy
 cache.log reports
a > of child proxy
   after almost every request we get the same
 2001/08/21 11:05:56| clientReadRequest: FD 17: no data to process
((11) Resource
 temporarily unavailable
b> cache.log of parent proxy
 NO SUCH "Resource unavail Messages"
not even once !!!!
  
===== now isnt this strange ======
so user clients like IE do hv problems but majority of ppl use MS iE
my particular version is Ie5.5

3> case 2 is some what similar to my earlier posting rgd web-polygraph
test when i didnt get these "resource unavailable errors" when
subjecting squid to polygraph test
demo.pg
  Robot R = {
        kind = "R101";
        public_interest = 50%;
      req_rate=7/sec;
        pop_model = { pop_distr = popUnif(); };
        addresses = ['10.1.11.225' ** 200];
        origins = S.addresses;
};
ploygraph showed ne abt 130 -150 replies/sec which was correctly shown
in mrtg!!!
4> to enable transparentrouting i had used ipchains on my machine
ipchains -A input -s localhost/32 -d localhost/32 -j ACCEPt
ipchains -A input -p tcp -d 0/0 80 -j REDIRECT 3128
ipchains -A input -s 0/0 -d 0/0 -j ACCEPT

under load i cpatured netstat -an
then did grep SYN_RECV | wc -l
the o/p was abt 1024 to 1030
this is at putting the machine atload for not more than 10 mins
does this indicate a SYN flood
do i need to increase tcp_max_syn_backlog in /proc
or do i need to change tcp_syncookies

so to summarize it all i just say that browsers give me reosurce
unavailable problem

 so joe .. i hv followed adrians advice.. (tried out stable 2.4 and not
daily snaphot..sorry ...)
tried using 2.4S1 without tranparent proxying now what remains to be
done is remove raid 0 and see if that makes any difference
btw i hv the tlan driver module

waiting for any further guidance

still optimistic,
khiz
