Programming :: Unable To Fix Syntax Error In Finding Ip Address Of A Host Name?
Apr 27, 2010
Writing a program that finds the IP address of a host name. Sorry forgot to include the line numbers, but where the $$$ is where the syntax error is. The errors are syntax error before "{" token and syntax error before "if". I've looked throught the code for a couple hours and can't figure out what's causing it. The code is attached below.
#define WIN
#include <stdio.h>
#include <stdlib.h>

I am trying to find IP address. In a socket programming tutorial, I found :
Code:
$ nslookup localhost
command. It gives me a address. However, one colleague told me :
Code:
$ ifconfig
It also returns me inet_addr. But both are different. Kindly tell me the correct method to find IP address? I have also checked the /etc/hosts file but it says "localhost"

I would like, from a C program, find the hardware MAC address of the default route path. With BASH I can do a 'route' find 'default and then an ifconfig and grep for 'HWaddr'. Are there C calls to do the same??

this issue which has suddenly occurred on both my Desktop and my Laptop. When I try to configure an IP address to any interface I get the following error....
uadmin@Ubuntu:~$ ifconfig br0 addr 192.168.10.1/24
addr: Unknown host
ifconfig: `--help' gives usage information.
uadmin@Ubuntu:~$
I get this for ethernet interfaces as well. I do not understand what is different as I was able to configure the ip address only the day before yesterday on the laptop..? The Desktop has had this issue for about 3 weeks now.
br0 Link encap:Ethernet HWaddr 32:70:40:91:06:25
inet6 addr: fe80::3070:40ff:fe91:625/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

I'm trying to troubleshoot some strange networking problems. The pattern seems to be that only newer distributions are affected. CentOS 5.4 and Ubuntu 8.04 work fine out-of-the-box. But Arch, Sidux, AntiX, Fedora, etc. show the same pattern of errors.Certain websites cannot be found unless I disable ipv6 in Firefox. And certain addresses cannot be resolved using various terminal commands (wget, apt-get, yum, etc.). What I would ideally like is a permanent solution, perhaps changing some settings on my router, so that I don't have to deal with this each time I test-drive a new distro. I have a hunch the issue has something to do with my DSL provider (Fairpoint) filing for bankruptcy.
One more piece of information that may or may not be relevant: I recently switched a website from one hosting company to another. I noticed there was a delay of several days where I saw the old version at the old host, but viewing the site at a friend's house or the coffee shop showed the new site on the new host. This leads me to suspect DNS issues perhaps, but this is not an area of expertise.

I'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.
But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused

I'm fairly new to shell scripting and am having the hardest time figuring out why this simple script is giving me an error
The error is "syntax error near unexpected token `else'
I'm using TextEdit on OSX (sorry I'm limited to this). The only thing I can think of is that it's reading some return character and getting thrown off. I've tried saving the script using different encoding types but the same error pops up.
I also get an error at line 2 because it does not regonize as a command

I am writing a code in bash script, in my ubuntu command terminal. The program should send the message, "Hello John!!" 5 times to john's terminal (assuming he is logged on to the server). But I keep getting this error: Syntax error: end of file unexpected (expecting "done").
#!/usr/bin/sh
clear
x=1 # this sets up the flag so we can have it send a limited amount
while [ $x -le 5 ]
do
write jdouglas << EFO
>Hello John!!
>EFO
x=$(( $x + 1 ))
done

I am trying to modify a script for research purposes and am having difficulty here as I have little prior experience with C-shell scripting.
The script looks as follows (it includes tcl commands like runFEP that you can ignore)
#!/bin/bash
for ((old=1, new=2; old<=4; old++,new++))
a1=${old}%50
a2=${new}%50
do
cat > input${new}.conf <<EOF
${a1}
code....
My question: I keep getting a syntax error when defining my two variables a1 and a2. I essentially need these variables to be
a1 = value of variable old divided by 50
a2 = value of variable new divided by 50

Okay, first off I'm no hotshot programmer (and actually lack much familiarity with shell scripting) so apologies in advance if this problem is so trivial as to be irritating.
What I'm trying to do is drop the following command from either a shell script or a perl program. However, while it executes fine and does what it's supposed to when entered from the command line, I can't get it to work as a system call.
Here's the line:
Code:
When I drop it from a shell script like this:
Code:
I get the following:
Code:
If I try escaping the ()s with or ', I get this:
Code:
I've tried a bunch of other stuff to get it working (deleting the ()s, spacing them differently, etc) and looked around online for a solution, but I can't find anything that works.
I tried a shell script directly only after anything I tried to drop it from perl with `` or system() failed with the same errors.

Im an academic (university networks and security lecturer) studying/teaching network and operating system security, and inspired by the work of Hovav Shacham set about testing ASLR on linux. Principley I did this by performing a brute force buffer overflow attack on Fedora 10 and Ubuntu 9. I did this by writting a little concurrent server daemon which accidently on purpose didnt do bounds checking.
I then wrote a client to send it a malicious string brute forcing guessed addresses which caused a return-to-libc to the function usleep with a parameter of 16m causing a delay of 16 seconds as laid out in [URL] Once I hit the delay I new I had found the function and could calculate delta_mmap allowing me to create a standard chained ret-to-libc attack. All of that works fine. However .... To complete my understanding I am trying establish where I can find the standard base address for ubuntu 9 (and other distros) for the following, taken from Shacham:-
Quote:
[code]....
/proc/uid/maps gives me some information but not the base address ldd also gives me the randomised starting address for sections in the user address space but neither gives me the base address. Intrestingly ... when a run ldd with aslr on for over (about) 100 times and checked the start point of libc I determined that the last 3 (least significant) hex digits were always 0's and the fist 4 (most significant) where between 0xB7D7 and 0xB7F9. To me this indicated that bits 22-31 were fixed and bits 12-21 were randomized with bits 11-0 fixed. Although even that doesnt define the boundaries observed correctly.
Note: I am replicating the attack to provide signatures to detect it using IDS, and for teaching purposes. I am NOT a hacker and if needed to could reply from my .ac.uk email address as verification.

I am a Novell (now defunct) CNE tring to learn Linux and am having a lot of trouble finding out where the WB 6-6 is wrong in the syntax for adding local4... the the syslog-ng config file. In the instructions there are discrepancies between commas and simi-comma, they are both in the statements in no particular order. there is no pattern to them. Here is what the book shows:
filter f_local4debug { level(debug) and facility(local4); };
When I try to input this in the Gnome terminal window to try and find out where it goes wrong I get the following: -bash: syntax error near unexpected token "(" If I can get the correct syntax I belive I can use the info to get past the rest of this portion of the lesson. I am desperate to learn Linux as the only jobs out there for a Novell CNE are migrations to MS, which really sucks, since MS really really sucks.
