General :: Proxy Delegate Refusing Connection?
Feb 12, 2010
My aim was to build a VERY simple smtp proxy under debian to handle mail from a port (51234) and forward it to the standard 25 port. I compile and install a "delegate" witch can handle easily that. It's working very well like that : delegated SERVER="smtp://anotherSmtpServer:25" -P51234
The strange thing is, it's working on my virtual test machine and on the dedicated server in local but I can't manage to use it trought internet. I test it like that. telnet [mySrv] 51234 Of course, no firewal, no deny host, no ined/xined, the service delegated is listening on the right port ... 2 clues : The port is answering trought internet with nmap as "51234/tcp open tcpwrapped" have a look at the tcpdump following :

I use Fedora 14 and Firefox as my web browser. I use Astrill VPN service. I have the following persistent problem: I start my computer. Astrill is not set to start on boot. I start Firefox. Firefox can not connect to anything, it says 'proxy server refusing connections'. I go to Edit>Preferences>Advanced>Network>Settings I click the radio button 'no proxy'. The problem remains. I am completely unable to connect to the net. Even on reboot, I cannot connect. On reboot, Firefox is set to use a proxy, although it was not on shutdown. Some init script is setting this. My normal connection is often faster than through Astrill, so I only really need to use it when I want to get at a website that is blocked by the govt here in China.
where Firefox is being told to use a proxy, and how to reset it to not use a proxy, assuming Astrill is not active. There must be something left in a .conf file somewhere which is overriding the settings in Edit>Preferences. Because, if I set it now to 'no proxy', I cannot connect to the net.

I am working on fc10. I connect to internet using two connections: with proxy and without proxy. Initially I had some problem in configuring yum for proxy and I resolved it by creating files proxy.sh and proxy.csh in /etc/profile.d with the required details (export_proxy).Now when I connect to my connection without proxy I have some problems .Whenever I try to do yum update I get the following error:
"[URL]: [Errno 12] Timeout: <urlopen error timed out> Trying other mirror. Error: failure: repodata/primary.xml.gz from adobe-linux-i386: [Errno 256] No more mirrors to try." what changes do I need to make in order to use yum in the connection without proxy?

I am trying to complete a update from Etch to Lenny but I am currently unable to access the internet via my debian server. I have determined I need to point to a contractor proxy for security reasons, however I do not know where to add the contractor proxy IP address.
what config file I need to modify?

On a bunch of servers, we use integrity checking tool on a large amount of data. Therefore, we compute SHA1 hash from a lot of files everyday. The CPU is a "generic" one, enough powerful for normal use, but get's totally saturated when integrity check begins. Is there any kind of server using a crypto-processor so as to delegate crypto functions to this dedicated processor?

I've been doing some security testing in a lab environment that does not have direct internet access. It's actually a little complicated: From home to connect to my lab machine, I
1. SSH to machineA.
2. SSH from machineA to machineB
where machineB is my actual lab machine. neither machineA or machineB allow anything other than SSH, and machineB is only accessible from machineA. However, I really need to run yum on machineB. I have managed to get internet access via Firefox on machineB by creating a series of SOCKS proxy via SSH.
1. machineB: ssh -L 12345:localhost:12345 user@machineA
2. machineA: ssh -D 12345 user@machineC
3. machineB: configure firefox to use socks proxy, localhost, 12345
where machineC has internet without limits placed. This is the only way I have managed to get internet working. I tried using ssh -L all the way from machineB->machineA->machineC but it didn't work (even when setting Firefox to use http proxy). I tried using ssh -D all the way, but again that doesn't work either.
I do have access via Firefox using socks proxy. However, yum update fails to retrieve mirror list, and from what I have found I don't believe yum supports socks proxy directly. Instead, it uses http_proxy / ftp_proxy. how to get yum to go out over the SOCKS proxy I created (same one using in Firefox)? It seems like since Firefox can access the internet and everything without issues, i should be able to get yum to tunnel through the same connection to access everything.... I tried

is there a way to force wget to use a specific squid proxy when making connections ? - I use a squid proxy normally, but I need this specific request to go via a different one. I dont have to use wget, I just need a way to test squid's blocking rules by requesting various pages through it, this proxy is not my normally proxy on the network and so I cant rely on wget taking the environment variable.
Also, this is as part of a script, so anything that avoids editing wget config files would be best. - Perhaps curl can do this ? - currently im using the exit code of wget to determine if the connection was made.

What I want to do is to share the internet connected to a computer with a telephone, over another telephone which is permanently connected to the pc.The thing is, that some guys found a way of making this on windows, in fact, I already set it up on xp and works like a charm, it involves configuring in a certain way the telephone, and to use 2 programs. One is CCProxy, which redirects the internet connection to the telephone, and another one, which updates the IP adress of the telephone connection to dyndns, so that I can put that adress on my second telephone as proxy, and this way, surf on the net through my home internet on the telephone anywhere. Tricky right?
Now, the thing is I don't like at all booting windows only for sharing internet with my telephone. So I want to do it in linux. I use Ubuntu and Puppy linux home.I tried setting up the connection to the modem with wvdial, and... I got connected! But hey, when I connect to the telephone, I lost my internet connection (main, cable based, the pc connection) :-S. I mean, somehow, the "active" connection for the browsers and all the internet programs is now the connection I have made with my telephone, which is plugged to the computer.Now my objective here is that NO CHANGE of active connections get done when I start the connection to the phone, and then, get a program like CCProxy, and a dyndns updater for sharing the internet connection on the pc, to the connection made on the telephone-modem wired to the computer.

We have two offices suppose A and B. At office A, we use centos 5.3 computer as router and squid proxy server. At office B we use a cisco router to connect to Internet. Computers at office A that has direct access to Internet can access computers behind cisco router at office B using vnc viewer. But computers at office A that can use internet only through squid proxy can't access computers behind cisco router at office B. Is there any way so that I could allow squid clients to access computer behind cisco router at office B using vnc viewer.

I cannot seem to get e2guardian to work. I went into Ice Weasel to adjust the proxy connections but that just blocks off all internet activity. The problem seems to be with the configuration settings in the browser. I tried Privoxy with a completely new Debian install and have the same problem.

Im running Ubuntu 10.04, currently living out of the country from where my server is located. We have a 4 Mbps dsl connection that speedtests fine to the closest server, and if we test from our present location to the speedtest.net server closest to our server the speed is great as well. When I SSH in to my server and setup a socks 5 proxy the speed goes through the floor. We barely get .2 Mbs. Whether I use putty or terminal from our mac, they both get the same slow speed. I've searched the forums and google extensively, but I haven't been able to come up with anything yet.

I use ssh to port forward my browser(firefox) using SOCKS to a "server"(ubuntu desktop with ssh ) I have in the UK, to watch iplayer etc wen traveling... I forward port 1024 (default port for SOCKS? **mite b untrue..). the "server" is running ubuntu 11.04.
could i set up a transparent proxy(squid) on the "server" in the hope tht it speeds up the connection etc... my thot was get squid to listen on port 1024, or set up the ssh port forwarding to the squid port... would tht work? is the a better/different way to do it? the issue is tht sometimes the ssh connection can b slow at times

I've got my netbook set up so that I can run a SOCKS proxy via my desktop machine. This works fine at home, but I'm wondering what happens at an internet cafe with public wifi.
Specifically, the connection needs initially to be set up with an ordinary direct internet connection so that I can log in to the cafe's router. I'm concerned that when I then set the network proxy to SOCKS host, the router will cease to recognise me and will disconnect me. This particular detail doesn't seem to have been covered in any instructions that I've seen (maybe I haven't looked hard enough).

Since I cannot upgrade Adblock Plus anymore because iceweasel is too out of date for the new versions, I am trying to give privoxy a try. I am following the howto Block Ads & Fast Caching w/Privoxy +Squid without success. I am always receiving the error:The proxy server is refusing connections Iceweasel is configured to use a proxy server that is refusing connections.Check the proxy settings to make sure that they are correct.
I added these lines to /etc/privoxy/config
enable-remote-toggle 1
enable-edit-actions 1
permit-access 127.0.0.1
Moreover, I have edited the /etc/hosts file to block urls providing adverts and anything I wanted rejected.

There are two Fedora 12 systems which are now refusing to hibernate. The hibernation sequence seems to happen but then things hang indefinitely with a black screen and a blinking cursor, top left. I don't know where to start looking for clues; what do I look for in the logs, could someone please point me to a good hibernate/suspend troubleshooting guide?
One of the systems just recently got out of whack, for no apparent reason; it hibernated great for a couple of years, even as it went through upgrades from Fedora 9. The other stopped hibernating after its F9 -> F10 upgrade. This one lacks non-root hibernation permissions, but when I issue "/usr/sbin/pm-hibernate" as root, it goes through the motions and then hangs at black screen also.

there seems to be a problem that has arisen with my beloved netbook (acer one 10.4")running Ubuntu Netbook. the mouse generally works fine (both menovering and clicking) while using the desktop, but as soon as an application is opened you are unable to click on any of the options within the application (buttons, etc). i have tested this over and over, and what seems to be the problem is that the pointer ignores the application and will always click the desktop.
i have used several diffrent mouses (both usb and trackpad) but the problem remains. i assume this means there it is a software fault. if anyone has ANY suggestions, advice, etc. feel free to post. would like this to be fixed asap!

I created a system backup ISO with remastersys that's about 3.4 GB, and I've repeatedly had failure and about 4 coasters now with both K3b and Brasero trying to burn it. I even ditched the original ISO and made another- same problem.I have always had problems burning discs in both programs, and of all the times I've tried to burn anything with either, I've gotten errors near the end of the data check stage, in verifying the data burned. I'm really tired of this, and I need this ISO perfect to reinstall my OS on a new laptop harddrive.This time it's K3b. It burned successfully, but I get errors in the data verification stage.

Having some problems, which seems to be the norm for linux mint 9.
Background: I decided I wanted to try LibreOffice out so followed the instructions here: [URL] to install libreoffice.
After a week I found that LibreOffice doesn't actually have a spell checker or thesaurus even though it says it does. Decided I'd had enough so uninstalled it and auto removed the rest of its gumpf and attempted to install openoffice which actually worked, before. Problem is I can't, linux mint wont let me and keeps outputting random rubbish that makes no sense ie:
Code:
spud@spud ~ $ sudo apt-get install openoffice.org
Reading package lists... Done
Building dependency tree
Reading state information... Done

The ssh server is running Xubuntu 9.04. It was working before. Then I tried SSHing today and it gave me a connection refused. The computers I've tried SSHing from were running Ubuntu Netbook Remix 10.04, MacOS, and Solaris 10. None of them would connect. The ssh server is running the latest version of openssh-server (according to apt-get install). I'm assuming something in /etc/ssh/ got changed but I'm not sure.

On my Debian 6.0 squeeze system, after reconfiguring GRUB and installing QEMU, X is sticking in 800x600 and not 1024x768. Yesterday I had no problems. Using a Rage Pro AGP 2X with 8 MB RAM (mach64 driver) on a i686 system. The kernel is the latest from squeeze's repo (2.6.32-5) and booted with the same settings as before despite the GRUB change to purge old 2.6 kernels.
