Hello,

I am setting up a linux server for gaming and I am using a script to update the files automatically and create a folder with a certain name.

Code:

# !/bin/bash

# A convenience function, to save us some work
update_server() {
	# Read the app id and the directory into a variable

	APP_ID=$1
	DIR=$2

	# Create the directory ( if it does not exist already )
	if [ ! -d "$HOME/$DIR" ]; then
		mkdir -p "$HOME/$DIR"
	fi

	# Uh-oh, it looks like we still have no directory. Report an error.
	if [ ! -d "$HOME/$DIR" ]; then
		# Describe what went wrong
		echo "ERROR! Cannot create directory $HOME/$DIR!"

		# Exit with status code 1 ( which indicates an error )
		exit 1
	fi

	# Call SteamCMD with the app ID we provided and tell it to install
	./bin/steamcmd.sh +login anonymous +force_install_dir "$HOME/$DIR" +app_update $APP_ID validate +quit
}

# Now the script actually runs update_server ( which we just declared above ) with the id of the application ( 4020 is Garry's Mod ) and the name of the directory we want the server to be hosted from:

update_server 4020 "gmodserver"

exit 0

When I run this script, it creates 2 folders on my server : gmodserver and gmodserver? There is no files downloaded in gmodserver. All the files are downloaded in gmodserver?

I looked for a few hours on how to solve this problem but I have no idea what the added ? might be so I am lost as to what to look for. Could you help me on figuring this out?

Thank you.

edit : I am using ubuntu 15.04 x64 if it makes a difference.

I need to compare a value with different fixed value. Below is the code concept I implemented in my bash script but its giving me error.
Here "a' is the nameserver value that I extract using command line from /etc/resolv.conf. I did not put command here.

#! /bin/bash
a=1.2.3.4

if [ $a == 1.2.3.4 || 5.6.7.8 || 8.9.1.4]
then
echo " You have correct ntpserver"
else
echo"wrong ntpserver"

fi

Am I comparing the value correctly or any suggestion?

Thank you

Hi, I need some help. I tried to install obs-ns. It´s based on ns2, but when I ran "make", the problem below appears... please I wish anybody would help me.


This is the error:

  sprintf(tcl.buffer(),"$ns nhops %d %d",src,des);

  char *ni = tcl.result();   <------this is the line 81 
  return atoi(ni);
}

Hello,

I am having issues connecting to my linux box (opensuse 11.3) from my Window 7 sytem. I am using FileZilla. When I attempt to connect I get this error message

Status: Connecting to 192.168.198.205...
Response: fzSftp started
Command: open "Mike@192.168.198.205" 22
Command: Trust new Hostkey: Once
Command: Pass: *********
Error: Authentication failed.
Error: Critical error
Error: Could not connect to server

I am thinking it is a setup on issue on my Linux box but not sure what to change at this point. I must have some settings correct, because I am able to remote into my Linux box using FreeNX. Any help would be appreciated
