Ubuntu Networking :: Setting Up Bluetooth Connection Between Two Computers Throws Connection Refused (111)
Apr 3, 2011
I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.
Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).
Any clues over here? I'm using pand 4.91 and blueman.
i m using RHEL5 on my server machine and open suse 10 on my client machine.both system ping each other, firewall is off of my server machine,i put a file from my client to my server machine using scp command but ftp command is not working when i want to open connection i receive a message "connection refused".what can be the issue?
I tried to finally set-up surround sound on my Ubuntu 10.04 machine and i was successful in doing so after a while of changing settings and tinkering. After doing so though, i was later in the day not able to get into the Pulseaudio Volume Control, therefore, everything is stuck where it is and i can't change anything. When i try to open Pulseaudio Volume Control i get the error message, Connection failed, Connection refused. My programs still play sound and i can control the sound of the programs through the programs, but i cant control the sound of the sorround sound now and my main sound bar only affects my stereo speakers, not the surround ones.
I believe this may have happened after the random disk check on restart, but i can't 100% confirm that and i'm not even sure if they are related. I still have sound, but i have no way to control the volume of my entire system at once. I did some looking around online and saw that others are having or had the same issue, and it was through different versions of Linux also. somehow reset everything so i can access PAVC and start over . I also tried steps listed in another thread here on the same topic, but they weren't working and it also seemed to be for older Ubuntu versions.
I need to browse the net more securely and bypass throttling by an infrastructure-dictator by creating a SSH Tunnel directly to my internet service provider and use it as proxy.
I tried both a dynamic and local tunnel, was a able to connect to the server and log-in just fine, but when I tried to surf I get a 'Connection refused' error.
Here's what I tried:
Code: ssh -D 8022 email@example.com -N ssh -L 8022:tunnel.host:8080 firstname.lastname@example.org -N (not at the same time of course)
Then I set 127.0.0.1:8022 as proxy in browser settings. As long as the tunnel is open the browser displays a blank page with no error when I try to open a remote web page, while the terminal gives me a 'Connection refused' error.
I'm using OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 on Xubuntu Hardy.
In case anybody is wondering this is perfectly legitimate. The tunnel.host I connect to is a server set-up by my ISP specifically for this purpose.
Either of the examples above should work as others who have the same ISP reported that it works. Therefore, I suspect this is an issue with my own security settings which are slightly on the paranoid side but I can't figure out what. Stopping ufw and explicitly opening port 8022 didn't help.
I cant connect with ssh to my workstation using my notebooks wireless lan. with cable I'm able to connect.so the funny thing is, if I first establish a connection from my workstation to my notebook (like ssh it or just ping the notebook) I'm able to create a ssh connection from my laptop to the workstation using wireless lan.scanning my workstation from the wireless lan of my notebook with
Code: nmap -sT -p 22 ventury says port 22 is closed
scanning it from the notebook with cable lan,it says port 22 is opened
scanning it from the wireless lan of my notebook an have sent a ping from the workstation before says port 22 is opened.ution.
I got a 64bit version of Kubuntu 10.04, up to date, installed on both, my workstation(ventury) and my notebook (defiant).the question is: Do I always have to ping my notebook first if I want to ssh from it to my workstation or is there some other solution? And why does it work fine with cable, but not with WiFi?
having a port 22:connection refused problem with SSH. None of what I have read has been what I have been experiencing, so I figured I would post here. The worst that could happen is this gets completely ignored, or I am told that there is already a solution, that I missed it, and directed to it. Here is my problem:
Just learned how to ssh into my machine a few days ago. Everything has been running smoothly until I ran into a little problem: all of a sudden I can't connect anymore. I have sshd-server installed and updated. I have sshd turned on
Code: /sbin/service sshd start And I even ran:
Code: /etc/init.d/sshd start Because I was told that it would start ssh from boot. Nothing has changed from today and yesterday and I haven't been having problems with port 22 being blocked.
I have also tried to ssh into the machine by the machine itself:
I get a connection refused error whenever I attempt to connect to a remote ssh server, I tried the test at and it says outbound ssh port 22 is not being blocked. I'm wondering what else could be the problem.
I forwarded ports 28900(TCP/UDP) and 5029(UDP) to my linux box for a game. Testing my ports with a website now shows these ports as "connection refused" rather than "timeout" which means the connections are getting to my system but the iptables are blocking them. But I added 28900 as a test and it still won't accept anything on this port. This is my output of iptables -L
Can you find my blind spot? I had PuTTY up & running untill I did a reinstall of Fedora13.I can ping 192.168.1.163 fine. SELinux is disabled. Firewall is default (SSH allowed on p22).I have just disabled the firewall with same result)
PuTTY reports: =~=~=~=~=~=~=~=~=~=~=~= PuTTY log 2010.07.20 16:23:52 =~=~=~=~=~=~=~=~=~=~=~= Event Log: Writing new session log (SSH raw data mode) to file: C:UserswimDesktopputty.log
I am facing connection refused error 111 in TCP client server program, in android native code which in C , but if code is in JAVA it works fine, but i want to continue in C only, in manifest file i have given permission and ip, port is correct .What am doing wrong?? or is their any network setting?? am using UBUNTU 10.04and If both client server Linux pc it works fine. only if android emulator becomes client then am getting connection refused
I researched a long while and could not find an answer to these problems, so here I am. I have a debian server running on my home network. I have it running LAMP and it has a live website.
I have samba running and share files with my windows 7 machine, so they do connect.
When i try to use putty it always refuses the connection.SQLyog tells me off too, but it only cays it cannot connect.
I was checking into SSH, since that is how they are both trying to connect, but I can not find adequate info online for my problem.
I have debian lenny running, I was pretty sure it has ssh running, but i couldnt locate 'sshd'
Is SSH on there by a different name or do I need to install the service.
(ps - getting samba running was a nightmare, but i think it was windoze fault, i tried setting up the debian machine exactly how the guides said to do, but it never could connect and denied passwords constantly, then the next day after a few windows reboots had happened, all of the sudden it worked. Don't know what the deal was there. Could that be instrumental? Sorry I am a web dev and not a networker so this stuff is not my forte.)
I cannot use GRsync from Ubuntu Desktop to PCLinuxOS laptop.The 2 computers can ping each other. I have disabled both firewalls. My laptop IP address is 192.168.1.11This is the error on Ubuntu Grsync:
ssh: connect to host 192.168.1.11 port 22: Connection refused rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.7] Rsync process exit status: 12
On PCLinuxOS it wont say Ethernet is connected when trying a static address setup.However it does connect to the internet via auto Ethernet setup and a LAN cable. It then says connected. In order to use SSH and GRsync what programs are required? I have these installed on both machines: grsync openssh-client openssh-server
I have installed ubuntu 11.04 and I'm now trying to connect to existing SUSE servers on the LAN. My home directory has a shared NFS mounted home on the SUSE servers while my home on the ubuntu machine is local. I can log in using ssh to all the SUSE servers except one. I get:
ssh: connect to host srv3 port 22: Connection refused
If I use the IP address of srv3 directly it works. Also, before I changed the default machine name ("ubuntu") I could log into srv3.
nslookup srv3 works OK. ping srv3 works OK.
Even if I completely delete the .ssh directory in both my ubuntu home and in my shared home on the SUSE servers I still cannot log in using the srv3 name, only direct IP address works. I'm thinking that the login I did to srv3 before I changed the machine name for the ububtu machine must have goofed up something
i done desktop config in ubuntu server 11.04 and connected via tightvnc,uvnc and in remote desktop viewer from another ubuntu machine also. I am not able to access(connect) the server in GUI mode(when monitor is removed) but i putty is working fine in cmd line.
I have my desktop computer (running F13) configured to accept ssh over port 22 via the firewall configuration tool. If I type ifconfig -a, this computer, which is running on my wireless network, tells me:
However, if I go to my laptop computer (also running F13) and try and ssh into the desktop, i.e. ssh email@example.com, I get this response:
ssh: connect to host 192.168.1.100 port 22: Connection refused.
I guess I am confused to what is blocking the connection? Is there another means on F13 other than the default Firewall? I haven't really messed with the network at all. For what it's worth, I am hoping to set things up so I can just ssh into the computer name, (ssh icthy@desktop) eventually, but want to start with the IP. So, can anyone offer a hint as to what I can look for that is blocking port 22?
I've got wired connection on my ubuntu and I set up a wireless network so I can share internet with other computers. I added another computer to the network, but it's asking for: * an IP address * router address * subnet mask. Where can I find these values?
i have two machines both on ubuntu 10.4 connected to a network via port switcher, 2 rj45 network cables auto eth0 is setup to share with other computers, i can ssh in and out of both, so the network is all running but i want to know how to share my single dongle internet connection between the 2 computers
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 126.96.36.199... telnet: connect to address 188.8.131.52: 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 have internet on my ubuntu machine (eth0) I am sharing with (eth1) My windows computers are getting IP addresses via DHCP from the Ubuntu Machine, and I can see (and use) samba/windows shares on all computers. Internet connection is not working on any of the windows computers.
I have eth1 set to "shared to other computers" under the IPv4 settings
Trying to share my internet connection with other computers on my LAN. I've tried doing this with Debian, Ubuntu & Fedora so far...
My Intended Setup is as follows;
The Problem: So far I've not been able to get an internet connection from any computer connected to the HUB. I currenty have Fedora 13 on PC1 but have also tried with both Ubuntu 10.04 & Debian Lenny. I am open to using any Linux based distro on PC1 as long it has a Gnome Desktop. eth0 on PC1 can be Static or Dhcp, but I would prefer to set Static IPs on eth1 & all of the Client PCs
To the best of my knowledge I have enabled ipv4 forwarding in sysctl.conf (& some other changes);
All changes I made to the Firewall (all other Firewall settings are still at default, no custom rules added yet);
Router is set up to assign dhcp from 192.168.xxx.100 & 192.168.xxx.200
At the moment I have only 1 PC attached to the HUB. It's Ubuntu 10.04 (PC2) It's details are; ip 192.168.xxx.103 netmask255.255.255.0 gateway 192.168.xxx.101
Thus Far I can't ping 192.168.XXX.103 from PC1 & I can't ping 192.168.XXX.101 from PC2. (unreachable) I have an internet connection on PC1 (of course)
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.
