Hello.
Most of the socket
articles I've read say that 5 is the normal value for socket.listen() backlog
parameter.
We're running a
server (written in Python) with the value set to 10, but during peak
periods, users complain that their clients (also written in
Python) "hang".
Here's the server
code :
===
import osimport
timeimport stringimport LoginParserimport structfrom socket
import *import thread
class
Start:
def startserver(self):
s = socket(AF_INET,
SOCK_STREAM) s.bind(('',
7878))
s.listen(10) print 'Login Server
started on port 7878'
while
1:
client,addr =
s.accept()
cl = "Got a conection from " +
str(addr)
print cl
ipaddress =
addr[0]
try:
msg =
client.recv(1024).split("~~")
p =
LoginParser.Start(msg[0],ipaddress)
client.send(p.reply)
except:
pass
try:
client.close()
except:
pass
def exitprog(self,event):
sys.exit(0)
def __init__(self):
self.startserver()
The
LoginParserver.Start ( ... ) queries a database to see if the username, password
given by the client is valid and returns some pertinent information to the
client.
The server runs
on a Pentium 4 with 512 MB of memory, running WhiteBox linux and Python 2.2
.
We've got about
1,000 employees / users all logging on / off during shift change and this is
when the problems are reported.
My question is, is
our socket.listen(10) enough ? Should I increase it ? What is the maximum value
for our particular server operating system ?
