Nginx Redirect

I have a nginx setup , and there is a redirect in the config to force https, so if a user enters domain.com, they get redirected to https://www.domain.com .

If a user enters https://domain.com, they get an error , because I have no host A record for domain.com, so I want to redirect https to https://www.domain.com when a user enters https://domain.com .

Sendmail Queries Part 2

Hi,

We are using Solaris 10 as sendmail gateway. We have just migrated our DNS recently. Now when a mail is sent, the system returned the following message:

# cat /etc/hosts | mailx -v <name>@<domain name>
<domain name>: Name server timeout
<name>@<domain name>... Transient parse error -- message queued for future delivery
<name>@<domain name>... queued

# mailq
/var/spool/mqueue is empty
Total requests: 0

I tried to stop/start sendmail but no luck to solve the problem.

Any pointer is appreciated. Thanks in advance.

Bash Script To Output Certain Lines From A File

I am trying to write a script to create a variable (string) out of specific lines from another file. The string will be used as headings for lists in another script. My plan is to create a variable "myvar" with the output from an awk command run against a file called banners.txt then I can call $myvar whenever it is appropriate in the larger script. additionally I can add/modify the banner file instead of having to comb through a large script to add or change echo commands.
So, here is my proof of concept script:
Code:
#!/bin/bash

path=/home/rstenger/

TESTFILE=$(<banners.txt)
MYVAR=$( awk 'NR > 6 && NR < 10' "$TESTFILE" )
#
echo ""
echo ""
echo $MYVAR
#
for i in {1..5}; do echo ""; done
echo $TESTFILE

exit

which produces this output:
Code:
sl7jump1~#->./test1.sh 
awk: cmd. line:2: fatal: cannot open file `******************************************************
*                1st banner has 3 line               *

What I was looking for is:
Code:
******************************************************
*                3rd banner has 3 line               *
******************************************************

I am very puzzled as to why I get the contents of the file in the awk error message, and the contents of my home directory as the variable.

Thanks,

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)

I thought it would be that simple...

Qmail Help

Hi All,
We have qmail server running on RHEL6.5. We have already made sure that our server is not acting as an open relay with the help of http://mxtoolbox.com/diagnostic.aspx.
But still anyone can telnet to our domain and send fake emails to anybody@ourdomain.com. For example Code:
telnet mail.ourdomain.com 25
helo mail.ourdomain.com
mail from: unknown@anyname.com
rcpt to: anyemailid@ourdomain.com
data
from: "Any Unknow name" <unknown@anyname.com>
to: "Some user Name" <anyemailid@ourdomain.com>
subject: Testing MTA with telnet

Hi,
This way anybody can fool us.

Regards,

.
quit

So can anybody pls help me to prevent this. I meant to say, we should not block port 25, instead it should verify whether or not "from email id" is exist in our domain, if it is exist then it should ask for the password also or if it is not exist then also it should not take us to next step. Because as per above example anybody can fool us as the mail is coming from outside but it is just from our domain to our domain without any authentication!!!
Expecting your kind help to block sending mails in this way.

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 homedir = /home/%D/%U
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]
comment = 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

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
