[isf-wifidog] wifidog segfault - error 6 in libhttpd.so.0.0.0

[Raul Andres Rodriguez Rodriguez]

Hi guys,

 

I have a problem with my Wifidog Gateway implementation, I configured in a server both, Authentication and gateway with the latest versions (20090925). All is OK, I configured the splash only mode for my node and started it, the captive portal works Ok, but when I have more than 70 users the libhttpd.so.0.0.0 crash, I saw the /var/log/messages errors and found lines like these:

 

 

Sep 21 11:29:55 server kernel: wifidog[15415]: segfault at 31324234 ip 006927c8 sp b57fc180 error 6 in libhttpd.so.0.0.0[68e000+6000]

So the wifidog daemon stop.

I increased the HTTPDMaxConn  parameter to 1000 , the result is the same, my wifidog.conf:

 

 

GatewayID UEX1

ExternalInterface eth0

GatewayInterface eth1

 

AuthServer {

    Hostname 192.168.16.1

    Path /

}

 

HTTPDMaxConn 1000

 

CheckInterval 3600

ClientTimeout 2

 

FirewallRuleSet global {

}

 

FirewallRuleSet validating-users {

    FirewallRule allow to 0.0.0.0/0

}

 

FirewallRuleSet known-users {

    FirewallRule allow to 0.0.0.0/0

}

 

FirewallRuleSet unknown-users {

    FirewallRule allow udp port 53

    FirewallRule allow tcp port 53

    FirewallRule allow udp port 67

    FirewallRule allow tcp port 67

}

 

FirewallRuleSet locked-users {

    FirewallRule block to 0.0.0.0/0

}

 

 

Thanks in advance for your help,
