I Need To Setup Kyless Ssh Between CentOS And HP-UX Both Ways

OpenSSH_6.7p1, OpenSSL 1.0.1f 6 Jan 2014

I am having trouble adding a ecdsa key to ssh-add
However, I can add a rsa key without problem.

My file permissions:
Code:

id_ecdsa miati:miati-600
id_ecdsa.pub miati:miati-644
id_rsa miati:miati-600
id_rsa.pub miati:miati-644
/home/miati/.ssh/ miati:miati-700

When I try to add rsa & ecdsa

Code:

$ ssh-add id_rsa
Enter passphrase for id_rsa: 
Identity added: id_rsa (id_rsa)
$ ssh-add id_ecdsa
Enter passphrase for id_ecdsa: 
Error reading response length from authentication socket.
Could not add identity: id_ecdsa

My command to create each key

Code:

ssh-keygen -t rsa -b 4096
ssh-keygen -t ecdsa

Hi,

I have a CentOS 6 machine [Machine X], which I connect to using a putty client or from another CentOS 6 machine.

Now, the machine X intermittently sends a connection reset message to all SSH sessions -

Code:

Read from remote host 1.1.1.1: Connection reset by peer
Connection to 1.1.1.1 closed.

I have switched off the firewall on the machine & there are no session timeout values set.

How do I find out what is causing this issue?


Thanks

I have CentOS 7 64 bit. I have installed open-vm-tools on it.
I have installed vmplayer using
Code:

./VMware-Player-6.0.1-1379776.x86_64.bundle

Now when I try to open vmplayer on it, it does not load 'Virtual Network Device'
and shows error in terminal
Code:

Failed to build vmnet.  Failed to execute the build command.

When I check status of vmware, it shows
Code:

Module vmnet not loaded

If I try to run
Code:

vmware-modconfig --console --install-all

It gives me following error.
Code:

make: Leaving directory `/tmp/modconfig-2NfFeS/vmnet-only'
Unable to install all modules.

I am not able to open VMplayer, please help me to open it.

Thanks

Hello,

I have CentOS 6.5 deployed as a VM on VMware ESXi. I want to force user to force password change even when they use VMware's vSphere client to access the VM console.

I tried the following two commands -

Code:

chage -d 0 username

Code:

passwd -e username

These commands force password change only when we start a SSH session for that user, not if that user access the VM directly via the client console. How do I achieve a force password change even when it is accessed via the client console?

Thanks

System Info:

I have normal user in CentOS 7 whose name is "mostafa" (the name of the account).

I naturally have another user called root with all privileges. User "mostafa" is put into sudoers file, too.

The OS is installed in VmWare, so the system is all mine.

Problem:

Now I create a file with touch file.sh and put a command in it, but when I want to run it with Code:

sudo ./file.sh

, an error is shown that the command Code:

./file.sh

does not exist. But if I Code:

 sudo chmod 777 ./file.sh

then it gets run. My question is that, why should I use Code:

chmod 777

when I myself have created the file, and I am in sudoers.

Can anyone explain me why shuold I still use Code:

sudo chmod 777

when the creator of the file is me.

Hello

I try to install the epel repository so I can install ejabberd.

I do not have epel, it seems :

Code:

[root@serv src]# ls /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-fasttrack.repo  CentOS-Media.repo  CentOS-Vault.repo  n2.repo

So I try to install epel :

Code:

[root@serv src]# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
Retrieving http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
Preparing...                ########################################### [100]
	package epel-release-6-8.noarch is already installed

But when I try to install ejabberd :

Code:

[root@serv src]# yum install ejabberd
Loaded plugins: downloadonly, fastestmirror
Setting up Install Process
Loading mirror speeds from cached hostfile
 * base: ftp.nluug.nl
 * extras: ftp.nluug.nl
 * updates: ftp.nluug.nl
No package ejabberd available.
Error: Nothing to do

Something is wrong with epel.

I have VirtualBox up and running on my headless Centos 6 machine, am using http://sourceforge.net/projects/phpvirtualbox/ as a GUI, and created a virtual machine and installed Windows 7 on it.

I can access it using the VirtualBox console (via phpvirtualbox interface), however, only can see part of the screen and the mouse doesn't work properly. I can also access it using Windows Remote Desktop Connection using IP 192.168.1.200:9000 (why port 9000?), but again the mouse doesn't work.

I have the following ext packs installed on the server.
Code:

Do I need additional extensions to better interact with the guest? How are they installed? Thank you

I have been using this command a lot lately:
Code:

sudo cp -r *.*  /<dest folder owned by root>

Goal: to copy all contents of current folder into destination folder.

I know there are other ways, and have tried several, but gave up in confusion (was also in a hurry to get on with it). Finally gave the windows *.* a shot, and it did exactly what I wanted.

Now that my task is completed, it would be nice to know what *.* literally means in Linux. I just looked though man cp, and also ran Code:

info coreutils 'cp invocation'

but didn't see any '*' options listed. Now I remember having come across '.' before somewhere, in the cp command, so possibly the '*' are ignored, and the only thing that matters is the 'dot'?

Hi,

On Centos 7 I haven't been able to configure phpmyadmin. I've got Apache 2.4.6 and I've installed the latest phpmyadmin, both with yum.
I've changed all the 127.0.0.1 to my public ip and I've disabled the 'denied all' directives. This is how it looks:
Code:

Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8

   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       Require ip X.X.X.X
       Require ip ::1
     </RequireAny>
   </IfModule>
   <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     #Deny from All
     Allow from X.X.X.X
     Allow from ::1
   </IfModule>
</Directory>

<Directory /usr/share/phpMyAdmin/setup/>
   <IfModule mod_authz_core.c>

   </IfModule>

     # Apache 2.2
     Order Deny,Allow
     #Deny from All
     Allow from X.X.X.X
     Allow from ::1
</IfModule>
</Directory>

# These directories do not require access over HTTP - taken from the original
# phpMyAdmin upstream tarball
#
<Directory /usr/share/phpMyAdmin/libraries/>
    Order Deny,Allow
    #Deny from All
    Allow from All
</Directory>

<Directory /usr/share/phpMyAdmin/setup/lib/>
    Order Deny,Allow
    #Deny from All
    Allow from All
</Directory>

<Directory /usr/share/phpMyAdmin/setup/frames/>
    Order Deny,Allow
    #Deny from All
    #Allow from None
    Allow from All 
</Directory>

on /var/log/httpd/error_log:
Code:

AH01630: client denied by server configuration: /usr/share/phpMyAdmin

The httpd.conf hasn't been changed except this:
Code:

<Directory />
    AllowOverride none
    #Require all denied
    Allow from all
</Directory>

Normal access to my apache works fine (a default test page shows up)

SELinux is disabled and I've also stopped iptables to test it.

Dear All,

I am trying to install a certificate and then authenticate with LDAP,
but I think I have been lost somewhere in the middle :

In a CentOS 7 system,
First, I would like to make sure that the certificate is installed and used :

Code:

yum install ca-certificates
update-ca-trust enable
cp cacert.pem /etc/pki/ca-trust/source/anchors/
update-ca-trust extract

When I do :
Code:

openssl s_client -showcerts -connect ...:636

Code:

openssl verify cacert.pem 
cacert.pem: OK

Code:

openssl version -d
OPENSSLDIR: "/etc/pki/tls"

Solved with :
Quote:
openssl s_client -showcerts -connect ...:636
