Debian :: Unable To Connect Or Ping Server In DMZ?

Apr 8, 2011

I'm trying to run Debian server in our network. We have SSG5 Juniper Firewall set up to route traffic from our trusted network 192.168.50.0/24 to our DMZ 93.153.125.224/28I can connect / ping all Windows servers which are in DMZ. When I try to connect my Debian server instead of one of the server's static IP I'm unable to connect or ping to it. The server itself is able to connect to internet resolve DNS if I allow connection to our trusted network I'm able to ping or connect to any computer in trusted network but still unable to ping from trusted to DMZ. The SSG5 policy is set up to allow any connection from trust to DMZ and interface is set up to route all traffic.I have tried to trace the ping It'll go through firewall right to the interface needed but then it'll time out as like the server is not connected at all.

Networking :: Ubuntu Server Cant Ping Or Connect External / Can Resolve Hostname And Domain

Oct 15, 2009

As the title suggest, I have downlaoded the latest copy of Ubuntu Server from the ubuntu website.Everything installed fine. DHCP configured ok as far as I can tell. I can ping other machines on my network (which are running Windows) and they can ping the Ubuntu machine and conenct to Apache which is running on it.If I try to ping google.com or any other domain, it gives the correct IP address but gives no response to any pings, dont telnet on port 80 (or any toher potr for that matter) on any machine on the internet. I checked the settings using ifconfig to see what DHCP had assigned, and they matched the windows machines configuration (other than the IP address obvisouly). I tried assigning a static IP, even reserving a particular IP for my NIC.

Whatever I do, i cant connect to any machine outside the network via IP or domain.I have searched everywhere and tried everything i can find on the net but still to no avail.The Windows machines are part of a domain called alcom-uk.local and run off of a Windows Small Business 2003 Server. Not sure if i need to manually setup Ubuntu to connect using a domain or anything.

Networking :: Can't Ping Past Gateway / Can Ping Server From Outside

Apr 29, 2010

So, I have an Virtual Machine running CentOS 5.4. It sits behind a hardware firewall which also does NAT'ing. I've set up plenty of these, so I know for sure the firewall and NAT rules are set up correctly. From the host, I can ping anything in my subnet and the gateway. But I can't ping anything else beyond the gateway. I can perform DNS queries and when I try to ping, it finds the appropriate IP address.But from the outside, I can ping the PUBLIC address (It's a 1 public to 1 private address NAT, not 1 public to multiple private). I've tried it with IPTABLES on and off, with no change.

General :: How To Connect To A Remote Server And Run Some Code On That Particular Server

Jun 30, 2011

I am implementing an automated backup scheme so I created a shell script which first creates SQL dumps for all MySQL databases, then retrieves all websites from the /var/www directory of a remote server. The latter is working as I am using rsync to get the remote files.However, the MySQL dumps being retrieved are the ones from the local server which is not what I want. I want to get the SQL dumps from the remote server as well.I have a tunnel between the local and remote server which I can connect to without using any password (I added the public key to the authorized_hosts), so I tried to add the following code to the script:

ssh user@192.168.x.xxx

I then attempted to retrieve the SQL dumps and exited from the remote server. However this does not work as I still have to enter exit manually in the terminal for the SQL dumps to be retrieved from the remote host. I don't know why this is happening. This is what the script is trying to do:

//connect to remote server
ssh user@192.168.x.xxx
//retrieve SQL dumps

[code]...

Is there a way to connect to the remote host AND run the script's code on THAT remote host?

Networking :: SSH To Server But Cannot Ping The Server - OpenSUSE 10.1?

Aug 10, 2010

I have a OpenSUSE 10.1 system on my college network and I am able to ssh to other college servers, but I cannot ping these servers. More importantly than pinging when I try install one particular program it needs to be able to access one of the college servers (which has the license for it) but it is not able to contact the server.I have installed this program on other computers (windows and redhat linux) on the college network and they can connect to the server (and they can also ping the server).But Idon't know how to fix this problem.I have googled lots of things but I am a bit bamboozled.I have turned off the firewall but it doesn't make a difference.

General :: Bash Script To Continuously Ping Server And Send Email

May 7, 2010

I'm trying to write a script that will continuously ping a server and then send out an email when the server is down, and then when it is back up. Then, continuing with monitoring. I would like to not run this in cron, because I don't want to script to run with multiple instances.

For example,
Ping a server every minute.
-If successful, do nothing.
-If failed to ping, then send out email stating that server is down.
-Once ping is successful, then send out email stating that server is up.

I only want it to send an email once after a failure, so the end user isn't get an email every minute that it fails. Once it is successful, then send the email (one time), stating that the server is up. Then, continue to ping and if fails again, repeat the process.

General :: Connect To An SFTP Server From A Windows Machine To A SFTP Server Using A DSA Key?

Jul 24, 2011

As a Windows user, I generated a pair of DSA keys from CoreFTP Lite and sent it to a third party that runs an SFTP server. They told me that a valid DSA key needs to have ssh-dsa at the start and the username@systemname at the end. CoreFTP generated neither the ssh-dsa header nor the username@systemname footer. I tried with WinSCP and it didn't generate them either. Is there a difference between how SFTP works between Windows and Linux? If I put a useraccount@systemname at the end of the text will it work? How would the Linux system validate that my system is called "systemname"? If it can't validate, what is the purpose of adding it?

Ubuntu Servers :: SSH Server - Connect To Server Via Port 443 I Get A Connection Refused Error?

Jan 7, 2011

I am merely trying to change the port for my ssh server.However it isn't changing.I edited my ssh_config file to:

Code:

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for[code]...

When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.

Server :: ERROR 2002 (HY000): Can't Connect To Local MySQL Server Through Socket

Apr 11, 2010

I've tried /etc/init.d/mysql start, and it actually starts, or at least, it doesn't error out. But when I do pgrep mysql I get nothing, and when I try to login with mysql -p as root, I get

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

None of my other logins work, either, but since pgrep mysql didn't work, it's clear that MySQL just isn't running. I tried uninstalling and reinstalling mysql-server via apt-get, but I get the same thing. The logs in /var/log/syslog show this:

Ubuntu Networking :: Error - Cannot Connect To Server - You Must Enter A Name For The Server

Apr 17, 2011

In Gnome Places->Connect To Server dialog, I am having problem using the Custom Location Service Type. I enter in the URI as

Code:

smb://username:password@ipaddress/share_name

I get an pop up error message that says:

Quote:

Cannot Connect To Server. You must enter a name for the server.

Which would be fine if there was actually a place for me to enter the name which there is not. What am I doing wrong. This is the first time I have tried using the Connect To Server dialog. Normally I just use a script I wrote to mount my share in a folder on my local drive as some programs cannot access the mounted network folder. In a browser all I have to do is:

Code:

smb://ipaddress/share_name

I tried using Windows Shares, but that did not work either. It does work if I click on network and access the share that way, but some programs like firefox and a few others that I want to save a file to my network drive do not show the network unless the share is mounted in a folder. So, I wrote a script:

Code:

#!/bin/sh
#mount ext storage drive
mount -t cifs //192.168.0.2/files -o username="username",password="password" /mnt/files

This works and I can use this, but it would be handy if I could just use the Connect To Server dialog.
