Yes, all of the necessary fields are there.
Starting nessus with -D shows nothing out of the ordinary.
Nessusd.messages displays "saving in /dev/null" once when I try to load
the plugin with the "Upload plugin option"
I also tried copying my plugin into an existing plugin file with the
same name and copied that new file (with the old plugin name) into the
plugin directory. Now I'm getting "Inconsistant data: Check for host
firewall [which is the name of the plugin I wrote] - not applying this
plugin.
Before I hijacked the existing plugin and uploaded my file separately,
it would display no messages and just not load the plugin.
The text for my plugin is below:
## Begin plugin
if (description)
{
script_id(99980);
script_version ("1.0");
name["english"] = "Check for host firewall";
script_name(english:name["english"]);
desc["english"]="

security policy and will not be admitted to the
network.
To resolve this issue, either enable a personal
firewall on your host or contact the Helpdesk at
555-1212.
Risk factor: High";
script_description(english:desc["english"]);
summary["english"] = "Determine if a host firewall is running";
script_summary(summary["english"]);
script_category(ACT_GATHER_INFO);
family["english"] = "Firewalls";
script_family(family["english"]);
exit(0);
}
if (islocalhost())
exit(0);
saddr = this_host();
daddr = get_host_ip();
sport = 1234;
dport = 55999;
pcap_filter = strcat('src port ', dport, ' and src host ', daddr,
' and dst port ', sport, ' and dst host ',
saddr);
ip = forge_ip_packet(ip_p:IPPROTO_TCP,
ip_src:saddr);
tcp = forge_tcp_packet(ip:ip,
th_sport:sport,
th_dport:dport,
th_flags:TH_SYN,
th_seq:rand(),
th_ack:0,
th_win:512);
# XXX maybe use tcp_ping()?
for (i = 0;i < 3;i++)
{
reply = send_packet(pcap_active:TRUE, pcap_filter:filter,
pcap_timeout:2, tcp);
if (reply)
{
flags = get_tcp_element(tcp:reply, element:"th_flags");
if (((flags & TH_SYN) && (flags & TH_ACK)) ||
flags & TH_RST)
{
security_hole(port:dport);
exit(0);
} # XXX else?
}
}
## end plugin

Subject: Re: [Plugins-writers] Trying to upload a custom plugin
Did you use all options like script_id, description etc.
Nessus need those.
The script_id have to bee unique.
When does nessusd.messages look like, any errors reported there,
if you start nessus like this (> 3.x) /opt/nessus/sbin/nessusd -D
does it shows some errors
