Ubuntu :: Update Error "Could Not Connect To 87.89.43.193:3128 (87.89.43.193), Connection Timed Out"
Mar 24, 2010
Five days back, i got a notification on top right side mentioning "The update information is outdated. This may be caused by network problems or by a repository that is no longer available. Please update manually by clicking on this icon and then selecting 'Check for updates' and check if some of the listed repositories fail."
So, i go ahead and click it.. it says it is downloading 1 of 19 files and after some time, i get the error mentioning "W: Failed to fetch [URK] Could not connect to 87.89.43.193:3128 (87.89.43.193), connection timed out"
I went into Software Sources and tried different servers from different countries, but there wasn't any luck. I also unchecked the repository that was giving the problem but nothing was getting downloaded from other repositories as well.
I have been getting these errors while running update manager and I can't seem to find specific information or how to resolve these problems. Was hoping someone could please provide me with some details about why they are occurring so I can deal with them myself next time and how I can go about fixing them now.

I am from India, and I tried to update my Ubuntu system today. Code: $sudo apt-get update The update failed because the connection to the India mirror timed out: Code: [URL] Could not connect to in.archive.ubuntu.com:80 (111.91.91.37). - connect (110: Connection timed out) I tried the update a few times, with the same result every time.
I had firestarter running at this time, and noticed that I would get new security events every time I tried an update. I checked the events list, and it turned out that the machine at the ip address 111.91.91.37 (the in.archive.ubuntu.com machine, to go by the above error message) had been trying to make connections to seemingly random ports on the machine every time I tried the update: see the attached screenshot. I then changed my repositories to the Main Server using Synaptic, and tried the update again (from the command-line). This time it worked without a hitch, and firestarter did not report any unwanted incoming connection. why is the India mirror trying to open connections that the Main server apparently does not need in order for me to do the update? Should I (we) be concerned?
I am relatively new to Ubuntu. Currently running Lucid Lynx, but I cannot connect to the internet. I can ping 127.0.0.1, and google.com. Software update works as well, but the connection times out when I try connecting to a web site e.g. bbc.uk.
when I try to connect via PuTTY from a windows machine I get " PuTTY Fatal error connection timed out. I try to do so via a router redirecting IPadr:86 to local adr:22 on the Linux machine.
I seems not to be a routing issue since the router is setup to redirect apparently correctly.
Well I have stopped iptables and selinux is disabled. The sshd deamon is running. I can logon with ssh locally "ssh webcamATlocal adr".
I get the below errors when trying to connect to the below repos.It has almost always worked in the past. Is the site "packages.medibuntu.org" down again !?
Err http://packages.medibuntu.org karmic Release.gpg Could not connect to packages.medibuntu.org:80 (88.191.82.11), connection timed out Err http://packages.medibuntu.org karmic/free Translation-en_CA
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've been trying to ssh out of my home network to school computers and I keep getting:
ssh: connect to host sage.math.washington.edu port 22: Connection timed out
I've tried this on my machine (running Ubuntu 10.04) and on a windows 7 machine (using putty). I have been successful ssh'ing to this machine using either of the laptops from every other network I've tried, so I'm pretty sure it's something about my home network.
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to server ["address"] port 22. debug1: connect to address "address" port 22: Connection timed out ssh: connect to host "server" port 22: Connection timed out
I suppose this is because I am connecting from a public institute where there is a firewall that is blocking an outbound connection on port 22.Is there anyway I can bypass the firewall using the internet ?
Is there any way to do remote desktop from Mac (Snow Leopard) to Centos 5.5?I have turned on remote desktop in Centos and got the address ([url].....) to access remotely. Then I installed vnc-Viewer in my Mac. Put the address like (mypcname.com:0) then clicked connect. I get error message "Failed to connect: Operation timed out (60)".My Mac and Cenotos is in the same network.
Linux printing appeared to be working fine up until yesterday. Today typing lpq gives the following: lpq Printer 'sdst@other.domain' - cannot open connection - Connection timed out Make sure LPD server is running on the server
The /etc/cups/printers.conf file is properly set, the printers appear in localhost:631 and they are printing test pages. However, all command line print commands seem to be trying to print to sdst@other.domain I don't know why printers.conf is being ignored and why and how sdst@other.domain was added. Seems like it might have been auto-discovered?
# dit: sdst@other.domain was mentioned in /usr/local/etc/lpd.conf I'm not sure why lpd.conf is being used instead of /etc/cups/printers.conf

I have SSH running on port 8662 and 22. I use 8662 for the outside world (eth0 which is 192.168 network) Here are the only lines I have changed in sshd_config:
Port 22 Port 8662 #Protocol 2,1
[code]....
BTW, ports forwarded on my firewall, checked and triple checked it.
I am building 1 system includes 1 firewall server using iptables 1 Webserver && 1 FTP server. On FTP server IP: 192.168.1.2 - GW: 192.168.1.1, I installed ProFTPD successfully. In LAN I do everything successful.

I am not so experienced with networking in Linux. I've successfully installed Red Hat Linux Enterprise 5.2 on a VMware host. When I issued nslookup command, it returns "connection timed out" error as follows:
Code: [root@rac1 ~]# time nslookup rac1 ;; connection timed out; no servers could be reached real 0m15.038s user 0m0.000s sys 0m0.000s
My questions are: (1) Is that error normal? (2) Is there a way to decrease the 15.038s value? rac1 is the local hostname, so why it takes all that time to resolve it.
Following info may help: Code: [root@rac1 ~]# hostname rac1.mydomain.com [root@rac1 ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost #eth0 - PUBLIC 192.0.2.100 rac1.mydomain.com rac1

In our development box we are configured postgresql to work with Jboss. The thing is we have firewall iptables in our linux box. when the iptables is stopped we can connect the postgres db locally using -h option, also we can connect thru a weblink we have created using Jboss. But when the iptables is started we can't connect the db locally using the -h option and the web is giving the below error. Caused by:
org.postgresql.util.PSQLException: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections. at org.postgresql.core.v3.ConnectionFactoryImpl.openC
I am having alot of trouble setting up evolution to work with gmail. I am using pop for recieving mail and it's slow but still works. When I try to send mail with smtp.gmail.com I get the error message that the connection timed out. How can I set this up to send and recieve email?
I have 2 different networks :the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping [url]..... on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7, CentOS 5.
I could say that the problem in DNS:because when I use this command in the private network machine: [url]...., it says connection timed out; no servers could be reached ,while in the public one, it works properly.....
I have been trying to solve this problem for two days now looking at various forums and websites but can't really figure out what's going on here.I have setup postfix on my ubuntu and I can send emails using "telnet localhost 25" and the ehlo thingy. Apache can also send emails. My problem is with incoming emails. When I try to send an email (through Gmail) I get the following error message:
Code: Delivery to the following recipient has been delayed: root@example.com
I've been using synergy on Ubuntu 9.04 and windows xp.Synergy 1.3.1 on both machines.My problem is that the server keeps cutting out. It seems to happen a lot when I watch flash videos on the server machine (ubuntu). This is what the server side looks like:
Code:
NOTE: synergys.cpp,500: started server INFO: CServer.cpp,1141: screen "server" shape changed NOTE: CClientListener.cpp,127: accepted client connection
[code]....
I dont think I usually get disconnected when doing other tasks. Mostly only when watching flash videos. Sometimes it doesnt automatically reconnect, and I have to kill synergys and restart it.
I've been trying since yesterday to install autoten per instructions below [URL]. However it has failed each time I have tried. Below is the terminal response.
Code: [colyn@Fedora ~]$ su Password: [root@Fedora colyn]# rpm -Uvh [URL] Retrieving [URL] curl: (6) Could not resolve host: dnmouse.org; Connection timed out error: skipping [URL] - transfer failed [root@Fedora colyn]#
I am doing a copy/paste so I am not mis-typing the information. It says that the connection has timed out but I get the error message within 5 seconds of hitting enter.
I have a problem sending emails in the command line. I have introduced this command:
sendEmail -f my.account@gmail.com -t myself@domain.tld -u this is the test tile -m "this is a test message" -s smtp.gmail.com -o tls=yes -xu usernameonly -xp mypasswd
But then I received this message: sendEmail[13230]: ERROR => Connection attempt to smtp.gmail.com:25 failed: IO::Socket::INET: connect: Connection timed out
