For the following compilation warning message I need to create some sample program in C for self study. Also I am looking for some good web link where all the C warnings are described.
1. Warning #47: incompatible redefinition of macro "entity" . Undefine macro before
2. Warning #167: argument of type is incompatible with parameter of type
3. Warning #175: subscript out of range

Is there an online resource to lookup error messages generated when compiling C++ code?
View 5 Replies View RelatedDoes anyoe have any example c/c++ code that is used to parse type-length-value messages.
The only decent article I can find on the web is:
http://en.wikipedia.org/wiki/Type-length-value
Bur it does not give any examples of parsing etc..
I have a syslog-ng running and kernel build of 2.6.34.8 I use a syslog API in my program with facility LOG_LOCAL5 and and levels debug err and crit and info. when I ran on the older syslog facility I had everything logged fine as I intended. now I have written these rules into the syslog-ng.conf:
options {
flush_lines (0);
time_reopen (10);
log_fifo_size (1000);
[code]....
the last two rules show my program gnssapp. the result is all debug levels or crit or err levels I don't see any of them !

View 8 Replies View RelatedI have designed a simple mail client to download messages/data to a file.
The server type is CAPA STLS which means can handle noncrypted and encrypted logins.
I have a problem which is that POP3 CAPA STLS mail server does not want to delete messages. It deletes the messages on the non STLS side.
For an STLS session, I receive the +Ok for a Deleted message.

I am writing a client chat server program in java. The chat server is already written. I created the interface and I connected to the chat server. The server keeps sending protocol messages to whom ever is connected, also it keeps sending specific protocol every 10 sec to check if user is still online.My problem is when I connect from my interface to the chat server, the program gets stuck, I can not press any other button because after connection my program keeps receiving commands from server(I have a method to keep reading after connection). How can I keep track of messages sent from server and not get stuck i.e press other buttons or type in the interface?
View 2 Replies View RelatedI was wondering if you could recommend a simple way to achieve functionality where received email messages are automatically processed and used in SQL commands (depending on certain criteria, of course). For example, say I have made a PHP-based blog application and it's located at example.com and I'd like to give members the option of posting to their blogs by sending email to a special @example.com address. The email messages received there will be inserted into a database depending on the sender's address, with the body becoming the post and the subject line becoming the post's title, etc.
Another example could be how those trouble ticket systems let customers submit tickets via email, while the support agents operate via a database-driven Web application. Is this the type of thing one must code from scratch, or is there an open source solution out there which only needs to be configured accordingly?
According to RFC 1939: "POP3 is not intended to provide extensive manipulation operations of mail on the server; normally, mail is downloaded and then deleted." However most of the mail clients have that option "Leave messages on server" after they have been downloaded. How is it done?
I tried sniffing mail traffic with Wireshark, but the only POP3 provider I have is Gmail and its POP3 access is SSL secured, so I was unable to gather any info from this... I tried downloading sources of Thunderbird and Evolution and checked what are they doing with "leaving messages", but it seems my C++ skills are not enough - I was unable to understand what is happening when "leaving"...
Suggest me some POP3 provider, that is providing unsecured POP3 access, so I could try again reverse engineering with Wireshark?
My script looks really crap and messy, the logic isn't great and I'm not hugely happy with it. Also it echo's $i instead of an actual IP address (line 10). How to improve this. It basically searches through /var/log/messages for multiple FTP hits and when the hit count is higher than a specific number the IP is added to a config file and ftp is restarted. There are some obvious flaws in my script.
Code:
MAXHITS=0
TOPHITS=`grep "FTP session closed." /var/log/messages* | awk '{print $7}' | sed -e 's/^.*[//' -e 's/].*$//' | uniq -c | sort -nr`
HITNUMB=`echo $TOPHITS | awk '{print $1}'`
IPHIT=`echo $TOPHITS | awk '{print$2}'`
HIGHIP=`echo $TOPHITS | grep $HITNUMB | grep $IPHIT | awk '{print $2}'`
if [ $HITNUMB -gt $MAXHITS ]; then
for i in $HIGHIP;
do
echo $i
sed -i '78s/$/,$i/' /opt/etc/proftpd.conf
/root/ftp restart
done
else
echo "not greater than $MAXHITS"
fi
I'm not even sure what will happen if I get multiple responses for my $TOPHITS. It would be cool if it could search for IP's already blacklisted somehow, it might actually be easier to just create a file with a set of blacklisted IP's or something.
