Networking :: Remote Connection - Unable To Connect
Feb 24, 2011
I was able to connect linux server on windows through putty.But now i am unable to connect that,I can able to ping that IP.SSH daemon is also running. shall i need to change anything in configuration file...
I did a clean install of the latest version of Ubuntu. For some reason, there are still internet-issues. When I tried out the following command
Code: telnet open ftp.microsoft.com 21 I got Code: telnet: Unable to connect to remote host: Connection timed out
Also, during install of the new ubuntu, it was unable to reach the repos for downloading. Odd thing is that I can go online, and that when I type 'ftp.microsoft.com' in my browser, it displays the file-hierarchy.
I am running CentOS 5.1 on VMware on Win 7 On CentOS I added Bridged network adapter and the server is connected to internet without any problems, but when I telnet any server on port 25 I get connection timeout.
telnet f.mx.mail.yahoo.com 25 Trying 22.214.171.124... telnet: connect to address 126.96.36.199: Connection timed out telnet: Unable to connect to remote host: Connection timed out
I stopped all servers, iptables and sendmail on the linux server and the firewalls on the win 7 but still getting the same error! I added new network adapter ( host-only ) and tried to telnet the win machine from vmware Linux but I got connection refused
telnet 192.168.71.1 25 Trying 192.168.71.1... telnet: connect to address 192.168.71.1: Connection refused telnet: Unable to connect to remote host: Connection refused
I'm trying to connect with my server via telnet, but when i sent the command (telnet xxx.xxx.xxx.xxx Port) doesn't works and shows then follow error: Unable to connect to remote host: Connection refused, It happens with any port. Is strange but my telnet services works (telnet xxx.xxx.xxx.xxx), In addition, i tried with firewall enabled and disabled and the problem still happens. My centOS run on virtualbox.
when i try a telnet to a host like that: telnet 10.10.10.10 1234 i got this: telnet: Unable to connect to remote host: Connection refused.
1/ does this mean that the problem is not due to a firewall, but that the host 10.10.10.10 doesn't listen on the port 1234? other way does this mean that my firewall is authorizing traffic on the port 1234?
and when i try a telnet on another port like that: telnet 10.10.10.10 1235 i get: Trying 10.10.10.10 ...
in this case this
2/ does this mean that the firewall is blocking the traffic between my host and the 10.10.10.10 on the port 1235?
I am doing some R&D on 11g RMAN in oracle at home. i have installed oracle enterprise linux and i have installed oracle software. when i am trying to configure listener, it is error-ed out. i have verified that telnet with the port is not working and i am seeing connection refused error.
I installed Ubuntu 9.10 on a friends computer when Windows died on it, and though she has had relatively few problems with it, she still occasionally has problems that are really hard to impossible to fix over the phone. She is also not very knowledgeable with computers, so I was trying to guide her through setting up so I could connect to her remotely and try to figure things out, but I cannot get it to work.
I personally don't use Ubuntu on my computer, I use openSUSE and KDE so that does add to the problem, though I have used Ubuntu and Gnome a lot in the past.
I had her go to remote desktop settings and allow connections from other computers and allow other users to control the desktop, and at first I had her require confirmation and a password but it didn't work without it either. When I try to connect, it just hangs for a while then times out. I tried using KRDC and just VNC in the terminal with the same result.
There should be nothing on my side preventing a connection, but I am not positive. I am not very familiar with remote desktop outside of a LAN either. I am just trying to connect using her IP address, I don't know if there is anything else I need to include. Is there maybe some other setting that needs to be changed or maybe her DSL modem/router is blocking me though I don't know why it would, especially since P2P programs work fine.
I install one server in my system(linux 5.0) and accessing that server through the 127.0.0.1 private ip address(lo). While i connect to a remote server for validating registry it gives me the error and unable to connect to remote server. here some of the files i give here in below to know my system network configuration
I'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.
But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused
I ve just install ubuntu 10.10 and am unable to connect to wireless connect. I was able to connect on the try ubuntu before install option. I have dual booted Windows 7 and Ubuntu 10.10. I have tried connecting without the WEP key and still no luck. Just found it strange that connect on try it but not after full install.
I have setup an OpenVPN server on Ubuntu server. I am able to connect with Windows clients. I am, however, unable to correctly connect using Ubuntu.
If the router firewall is blocking the pings to keep the connection alive, then the connection initially does not work, but will work after the first timeout and reconnect. If the firewall does not block the pings then the initial connection attempt never times and therefore the connection does not work.
Attached is the readout from the client.
The first attempt gives error ERROR: Linux route add command failed: external program exited with error status: 7
Successive attempts work, they just time out every two minutes.
I recently installed Ubuntu 9.10 on my Dell Inspiron 1545 64-bit laptop. Before that I used Windows7. In Windows, the internet connection worked perfectly well. But after installing Ubuntu, I am unable to connect to the internet. The network-manager applet finally says that "You are disconnected". When I do the "ifconfig", I got no IP address.
So, I installed Ubuntu 9.04 in the same system. But the problem persists.
I gone through many posts in this forum but nothing was useful.
I have just installed ubuntu 10.04 using the wubi installer to dual-boot my machine. Under ubuntu, I am not able to connect to the internet or my router. Everything works fine under windows. I have tried to find relevant information in the forums, but nothing seems to work for me. I have tried disabling ipv6, setting a static ip, but no go. ifconfig shows no IP, dhclient results in no DHCP offers and pinging my router's IP results in Network is Unreachable.
I have a problem with my Terminal Server Client, I cannot seem to connect to any windows server via IP address. Can anyone please recommend any tool I could use to connect? I need to work on the server for admin interfaces example Admin Kits for workspace protection
I installed dovecot on my server and now the imap and pop3 ports are open.But when I want to telnet it, it's not possible.Code: Trying 127.0.0.1...telnet: Unable to connect to remote host: Connection timed out.Also I can't any ports else. But I can connect to it from other computers. I tried to connect to this from my PC and it was successful.
Trying to get OpenbavoPOS to connect to my remote Postgresql database, but so far i've only been able to connect to the local postgres installation. I _am_ able to access the remote databases with psql. I've read literally dozens of pages, and am pulling my hair out. I'm trying jdbc:derby.//192.168.15.10:5432/bravo I get back java.sql.SQLException no suitable driver found for jdbc:derby.//192.168.15.10:5432/bravo If I use jdbc:derby./root/bravo - all is OK, using a local database created in /root I have jdk installed on the client; does it need to be on the server also?
Server = CentOS 5.4 PostgreSQL version 8.1.21 Client = CentOS 4.8 PostgreSQL version 8.1.4
I am using Empathy IM client to access to gadu gadu and to message with my friends. The strange thing that is happening is that I keep on being connected and then disconnected and then connected again even if I am continuously connected to my internet connection (no problem when surfing or using skype for example)It also seems to come only from me because when my girlfriend is using the same gadu gadu on her windows laptop simultaneously, she doesn´t get disconnected (whether when she is at home and using the same connection as I am or when she is outside, meaning that it doesn´t seem to come from the whole gadu gadu network)maybe it has something to do with the ports that gadu gadu is using but it is strange that sometimes it is working for a period of time and then not and then again.
I have a new Ubuntu server (10.10), named Denholm, recently installed and updated. I came in this morning, attempted to add a package with apt-get, and got a "Connection refused" response. I have another server (also 10.10), named Moss, on the same network that can connect successfully.
Here's what I've found/tried so far:
This doesn't look like and apt problem anyway, but the sources.list files on Denholm and Moss are identical.
I can ping [URL] (and other sites) successfully from Denholm.
I have tried 'wget www.google.com'. From Moss the wget is successful, but from Denholm I get "Connection refused."
I have a web server on Moss and Denholm can successfully access it.
To the best of my knowledge, Denholm is not configured to use a proxy server (no http_proxy variable set).
I have just installed Ubuntu 10.04 on my HP Pavilion dv5. My laptop has a Broadcom 4312 wireless adapter. The driver for the adapter was installed by Ubuntu as a proprietary driver. The wireless light is on and I can see the available networks, but I am unable to connect to my network. The correct authorization is set(WPA/WPA2) and I have entered the passphrase correctly.
I am able to connect to the wireless network successfully from my Windows login(that is how I confirmed that the passphrase is accurate). The network shows that it is trying to connect, but the wireless authentication dialog(asking for the passphrase) keeps popping up. Incidentally, the same thing happened when I tried openSuSe and Fedora on a spare laptop. The windows systems can connect, but not the Linux systems.
