NFS Security

I would like to give access to NFS share to host 192.168.1.11 only and I made following entries
# vi /etc/exports
/common 192.168.1.11/24(rw,sync,root_squash)

# service nfs restart
# exportfs -av
# showmount -e

I have a test box with IP address of 192.168.1.5, This box can access the share. I want only 192.168.1.11 to access the content of share. ANY thoughts?

Need Help In Bash Scripting

I have two files which has exact same number of lines.
I want first line of first file should be filename of new file and content of this new file should be first line of second file.
Then second line of first file should be filename of again new file and content of this new file should be second line of second file.
then third line of first file should be filename of again new file and content of this new file should be third line of second file.

This is what I have done
Code:
IFS=$'\n'
var=$(sed 's/\"http\(.*\)\/\(.*\).wav\"\,\".*/\2/g' 1797.csv) # filenames of all files

for j in $var;
do
#Here I do not know how to use $var2

What Does A Dot Character Mean In Linux?

Hi folks,
i was reading a tutorial about how to find files and folder sizes and came a cross this example

Quote:
root@host [5045 02:30:13 /home/johnc/public_html/wp-content]# du -h --max-depth=1
613M ./cache
4.0K ./reports

4.1M ./ewww
4.0K ./upgrade
226M ./uploads

1.7G .
You see at the bottom it indicates a 1.7G . (dot) . what does that dot mean?

Yum Update Caused Problems

Hello
I installed fedora 18 on an older apple computer (i.e. replaced the operating system with eight cores). To make a long story short, I did a "yum update" which took hours to complete, but when I attempted to restart my system, I now get the Grub boot loader coming up and showing that the fedroa3-11.10-100fc18x86_64 OS is staring up, but then suddenly the screen goes black and I get a weird message:

" radeon 0000:02:0:Invalid Rom content
system[1]:Job multipathd.service/start deleted to bread in g cycle starting with basic./start"

So, I then place on a USB containing the original fedora 18 I installed earlier, but now, I cannot, using the Grub Menu, to locate the usb or the cd option.

I have tried looking at sites on line for help, but so far nothing has worked...

Can someone help me...I am a Newbie.
Thanks

500 Internal Server Error When Using The Mod_rewrite

Hello.

I have such links in a web site

/post.php?id=14
/cat.php?t=y&cid=6666

and i create an .htaccess file with that content inside.

Code:
Options +FollowSymLinks 
RewriteEngine On 
RewriteRule ^([^/]*)$ /post.php?id=$1 [L] 
RewriteRule ^([^/]*)/([^/]*)$ /cat.php?t=$1&cid=$2 [L]

but on refresh, apache returns 500 Internal server error.

I looked on logs and found that :
Quote:
AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
Why that happens ? Mod_rewrite is enabled in httpd.conf.

Centos 6.6 And Samba 3 - Can't Get Domain User To Login

Hi All

I have been racking my brains for the past 15 hours or so trying to know why my AD users can't actually login to the share which i have assigned.

This is my smb.conf below:

Quote:
[global]
workgroup = EXAMPLE
security = ads
realm = EXAMPLE.GROUP
domain master = no
local master = no
preferred master = no
printcap name = /etc/printcap
load printers = no
idmap backend = tdb
idmap uid = 10000-99999
idmap gid = 10000-99999
idmap config EXAMPLE:backend = rid
idmap config EXAMPLE:range = 10000-9999
winbind enum users = yes
winbind enum groups = yes
winbind use default domain = yes
winbind nested groups = yes
winbind refresh tickets = yes
winbind offline logon = true

template shell = /bin/false
client use spnego = yes
client ntlmv2 auth = yes
encrypt passwords = yes
restrict anonymous = 2
log file = /var/log/samba/samba.log
log level = 2
valid users = any
[Research]

path = /sharing/research
valid users = EXAMPLE\user1
force group = "domain users"
writable = yes
read only = no
force create mode = 0660
create mask = 0777
directory mask = 0777
force directory mode = 0770
access based share enum = yes
hide unreadable = yes
[Admin]
comment = Admin Area
path = /var/www/html/cmsmadesimple
browseable = yes
writable = yes
read only = no
inherit acls = yes
inherit permissions = yes
create mask = 700
directory mask = 700
valid users = user1

When i do wbinfo -u or wbinfo -g i can see the usernames and groups in my AD.

Also when i do : id username it actually gives me the information for that user in my domain.

I have done net ads login -U and joined the domain.

I have set the pam auth modifications and the krb5 and nsswitch.conf files.

So i do not get why i can't have the user i have assigned to that share access it?

I can only imagine i have something wrong in my smb.conf?

Please any helps would be appreciated.

Thanks

Search Function For FireFox Browser?

It is too bad there is no search capability in the Mozilla browser. While reading large pdf files I am forced to copy their content into gedit and use its search tool.

Is there a way to change that? Thanks, - A.

Problem With Running Bash Script

Hi

I have just started to use Linux on my Raspberry Pi to host a home automation server & I'm having a problem when trying to run a bash script.

The script in question is to turn off my Viera TV & is as follows
Code:
#!/bin/sh
curl -i \
-H "Accept: text/xml" \
-H "Cache-Control: no-cache" \
-H "Pragma: no-cache" \
-H 'SOAPACTION: "urn:panasonic-com:service:p00NetworkControl:1#X_SendKey"' \
-H "Content-Length: 200" \
-H 'Content-Type: text/xml;charset="utf-8"' \
-X POST --data '<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> \
<s:Body> \
<u:X_SendKey xmlns:u="urn:panasonic-com:service:p00NetworkControl:1"> \
<X_KeyEvent>NRC_POWER-ONOFF</X_KeyEvent> \
</u:X_SendKey> \
</s:Body> \
</s:Envelope>' http://192.168.1.87:55000/nrc/control_0/

If I run this from the command line it works fine but when I try to run it from within the Home Automation application it returns error code 32512 which I've seen elsewhere is actually exit status 127 & basically down to not being able to find the program to execute.

Permissions are fine & I've tried using the full path name for both curl and the script itself but I still get the error. Has anyone any idea what I need to change as this looks to be a pure Linux (or rather my misunderstanding of Linux) issue rather than the home automation program

Thanks

Automating Script To Run Every Minute Through Other Manually Created User Using Crond

Hy All,

I have two nodes running RHEL 6.4 which are in cluster. I have clustered httpd service. Now I have certain application suppose X which reside in SAN partition. Now my job is to only automate this script to run by analyzing httpd status. I have successfully created the script apptrigger.sh whose content is given below,

-bash-4.1$ cat apptrigger.sh
a=0
b=0
c=0
d=0
a="service httpd status"
b=`eval $a`
##### CHECKING WHETHER HTTPD SERVICE IS RUNNING OR NOT #####
if [ "$b" != "httpd is stopped" ]; then
c="bash /switchapp/switch/ezlinkenterprise/bin/ezlink-cluster.sh status"
d=`eval $c`
##### CHECKING WHETHER EZ IS RUNNING OR NOT #####
if [ "$d" != "EzTaskMgr is Running" ]; then
ezstart
fi
fi

I have created this script in say test user. Now when I put this script to automate or run every minute through test user and defined its value in crontab -e of test user whose content is as shown below
$crontab -l
* * * * * /bin/bash /home/test/apptrigger.sh

but this script is running as root user so I cannot get the o/p
I think some environment variable need to be set. Anyone can guide me with this step? Thanks for your views and suggestion.

Problem With Samba Share

Hello

I want to share a folder on my Fedora linux pc with a Windows 8 pc in the same network.

I have followed this guide : http://www.labtestproject.com/config...rver_on_fedora

but I am not able to see my share on my Fedora linux pc from the other Windows 8 PC.

This is my /etc/samba/smb.conf :

Code:
[global]
        workgroup = mygroup
        server string = HP Samba
;       netbios name = MYSERVER

;       interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24
;       hosts allow = 127. 192.168.12. 192.168.13.

;       max protocol = SMB2
[My-Documents]
        path = /home/Jonas/Desktop/My-Documents
        read only = no
;       browseable = yes
        guest ok = yes


The workgroup name is the same as the workgroup name on the Windows PC.

Firewall on Fedora linux pc is down.

I do get the following output when restarting smb :
Code:
apr 27 12:27:49 jonashp.domain.local systemd[1]: Starting Samba SMB Daemon...
apr 27 12:27:49 jonashp.domain.local smbd[4324]: [2015/04/27 12:27:49.686796,  0] ../source3/param/loadparm.c:3034(lp_set_enum_parm)

apr 27 12:27:49 jonashp.domain.local systemd[1]: Started Samba SMB Daemon.

I thought it would be that simple...
