I want to access the timestamp field of the packet being sent or received. I am not getting clear idea as to which ioctl I should use, and how it should be used in the program. Anyone explain rough flow of the program for accessing the timestamp.

I've implemented a python script in conky that shows my stock portfolio.But, in the output of last updated timestamp, I get a time several hours in the past. The url for fetching stock data is: [URL]This is a norwegian stock, and I also live in norway. So the timestamp is not translated to the stock market of where it came. I can't find any 'localizing' stuff in the url either.Now my question is this: The script puts the time into a variable, the varable now contains ex 11:23 Is there any way I can add 6 hours or so to this variable
View 3 Replies View RelatedI got a directory with files in it like: 2006-07-01.foo2007-08-04.foo I need to update the timestamps on these files using "touch -t 200607010000 2006-07-01.foo" on each file in the directory so I came up with the following one liner:
for i in `ls -1`; do touch -t `ls -1 | sed -n 's%([0-9]{4})-([0-9]{2})-([0-9]{2})(.*)%1230000%p'` $i; done
My goal was to use sed and get the timestamp for touch and then loop through each file and touch with the timestamp.However the script, not giving me the results I intended. Can anyone chime in on what I am doing wrong?I have been banging away at this for a couple of hours now and am clueless on what it could be. I also tried another variant such as:
for z in $(ls -1 *.foo); do echo $z $(for i in `ls -1 *.foo | sed 's%([0-9]{4})-([0-9]{2})-([0-9]{2})(.*)%1230000%p'`; do echo "$i"; done); done
I am using makefile to complile all C Programming files. But certain files are not getting compiled and hence its object file is not getting generated. This is happening due to files haven't been modified for a long time. It seems that compiler knows that its object file is there hence no need to complie it actually it is not.

This is a watered down version.
Code:
I need it to either not add the time stamp if the awk finds a duplicate or write over the time with the new time if awk finds a duplicate.
BTW this is all pretty much cut-and-paste scripting so please feel free to comment if you know a more elegant way.
I have a directory listing with many subdirectories having many files. I want to recursively search for the oldest 5 files starting from the base directory and not 5 from each subdirectory. I am writing a shell script which sorts them using ls -lRtur|egrep "txt|jpg" > /tmp/file1 Now from this /tmp/file1 file I want to sort the files same as what the ls -ltr command does that is oldest file time to newest file time first. How do I sort based on Linux time stamp? The files itself also have Linux timestamps embedded in them So I can sort based after extracting them as well if it is easier.
My /tmp/file1 has entries like below.
-rw-rw-r--. 1 usr1 usr1 705 2010-01-22 17:25 sample20100603173659.jpg
I want to get the 5 oldest files and then delete them.

I'm a newbie trying to modify a DNS-formatted UDP packet. I am piping DNS replies through a firewall queue where I get the packet with $udp_obj->data provided by NetPacket::UDP. Is there a command line application that will break down the udp packet for me so I can extract an answer? Cpan doesn't have a module to do this. One can *create* udp packets programmatically or get them off of libpcap, but I don't need either.

View 1 Replies View RelatedCan someone help me with this problem,trying to send a packet,using tcp/ip,the packet should look like this:
Code:
field 1: SOCKS protocol version, 1 byte (0x05 for this version)
field 2: status, 1 byte:
0x00 = request granted
0x01 = general failure
0x02 = connection not allowed by ruleset
0x03 = network unreachable
0x04 = host unreachable
0x05 = connection refused by destination host
0x06 = TTL expired
0x07 = command not supported / protocol error
0x08 = address type not supported
field 3: reserved, must be 0x00
field 4: address type, 1 byte:
0x01 = IPv4 address
0x03 = Domain name
0x04 = IPv6 address
field 5: destination address of
4 bytes for IPv4 address
1 byte of name length followed by the name for Domain name
16 bytes for IPv6 address
field 6: network byte order port number, 2 bytes
and this is my code:
Code:
int domainLen = strlen(domain);
char reply[domainLen + 7];
reply[0] = 5; // version
reply[1] = 0; // succed
reply[2] = 0; // reserved
reply[3] = 3; // its a domain

for(int j = 0; j < domainLen; ++j)

}
reply[5 + domainLen] = 80; // port
reply[20] = '�';
Send(reply, sizeof(reply));
domain is "www.google.com". Am I doing it right ? I dont know much about bits.

View 1 Replies View RelatedI am trying to generate a UDP syslog packet from my C application. But I am facing a problem with a Cisco Router ACE that does not like the Source Port being '0' and thus drops the packet.How can I specify the Source Port in the UDP header to '514' as stated in RFC3164 (Section 2: Transport Layer Protocol)? "It is RECOMMENDED that the source port also be 514 to indicate that the message is from the syslog process of the sender"
View 1 Replies View RelatedI'm beginning to write a custom RTP implementation and want to test its resilience to UDP traffic. I've searched on the web and all the links I can find are for analysing actual traffic, not generating it or messing it up.
Does anyone know of any software (preferably free software) that will, for example, take actual UDP traffic and drop packets, duplicate some and make some arrive late/out of sequence?
I have found many examples out on the www for creating udp servers with sockets. The problem I am running into is after I receive the packet from a host I need to be able to send a custom made packet(I'm using RawIP / NetPacket to make my packet) back to this host. The only way to do this is seemingly through the send() function. This function however doesn't appear to allow me to specify which host to send my packet to.

View 1 Replies View RelatedI have a directory containing files and symlinks to files elswhere. I make a copy of the directory like this:
cp -rp dir/* new_dir
The files in new_dir have their original timestamps, but the symlinks have the current time. touch -t does not operate on the symblink but on the files they reference. Is there a way to set the timestamp of the symlink to a time in the past?
How do I compare the timestamp of two files? I tried this but it doesn't work:
file1time=`stat -c %Y fil1.txt`
file2time=`stat -c %Y file2.txt`
[code]....
I printed both the time stamps, in order and it gives me
1273143480
1254144394
./script.sh: line 13: [1273143480: command not found
So basically if comparision is not working, I guess. Or if there is any other nice way than what I am doing, please let me know.
Edit: There was no space in between if, so changing it to this works:
if [ $file1time -gt $file2time ]
I recently hired a new tech guy to start managing our servers. In doing this I went ahead and upgraded all the servers. It has been awhile now since I sent him the details of the new server and the last time I talked to him he was joking around with one of the other clients not realizing how long it took.
I know on other server moves, my old guy could have everything setup and running in a couple days as a good amount of time is waiting for the data to copy over. I am starting to wonder if this guy is going to try and throw a huge bill at me, so I would like to know what hes doing on the server with time stamps just so I can get a idea of how much time he has been logged into the server. Does this server OS have anything like this built in?
I was wondering if anyone knows how to change the timestamps of folders recursively based on the latest timestamp found of the files in that folder.

total 55220
drwxr-xr-x 2 jon jon 4096 2010-08-30 12:34 ./
