'm trying to access remotely to my computer that is in my home with a VNC client. The problem is that from my company site, I'm behind a proxy and I must use this proxy to connect my computer.I'm new to the vnc programs, so I don't know how to define a connection to use the proxy. My laptop is well configured, the only problem is set a vnc client to use a defined proxy. 1 - I've installed VNC viewer or tightvnc viewer, but I can't find any option in it to define a proxy. How can I define a proxy in this program?2 - Is there any vnc client that allows to define a proxy?3 - Should I define a tunnel that redirects my connection to my remote PC? For example, if I define a tunnels that from localhost:5656 it connects to my remotePCort through the proxy will I hane any problem
I have recently configured squid proxy server in rhel5 so now I am able to blocking some websites ok, but still I have one problem how can I block gtalk by using squid proxy, one more thing I blocked gmail so now client xp systems are not logging into gmail but still they using gtalk to chatting the things to others. So ultimately I need to block gtalk also by using squid proxy.
How can I use a torrent client in a network where bittorrent or any thing like this is blocked. I am aware of a combination of socks proxy with torrent client but not exactly sure if this is the thing I need.
I am using ubuntu 11.04. I want to know that how can I set proxy settings for Transmission bittorrent client?I fill the settings in network proxy but it won't work for bittorrent.
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.
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.
On Linux, the Ctrl-[ key combination appears to be equivalent to hitting the Esc key. I would like to define Ctrl-[ as a shortcut in emacs but I am unable to because by the time the keystroke gets to emacs it looks like the Esc key was pressed. Is there anyway to disable this behavior so that Ctrl-[ simply means Ctrl-[?
how can I define file type for wget to download . for example I do not want to download *.html or I just want to download *.jpg files . or if it does not support any of them do you know any other suggestion ?
When installing Linux,sometimes i tried to install that on my second hard disk, which is set to be a dynamic disk(named hdb),but a message said that: root is not defined for hdb. -What does that mean? Does it mean that a Linux driver must be opened on that hard disk? if so:where do i find a linux driver
I have created a new user define chain # iptanles -N blacklistNormally when we add a new rule it automatically insert in the default iptable but when we create a user define chain then how can I add my rules in this chain ?
this seems like it should be a simple thing, but I can't find it. Is there a bash shell command that allows you to create a string of repeated characters? Like a string of 100 '*'?
I'm on Mageia Linux Cauldron (what will become Mageia 2), where Mageia Linux is a recent community fork of Mandriva Linux. this script gives me the Xkb layout that I need:
why do we have to define both Source/Destination AND Direction when building firewall.Isn't direction= source->destination? what would happen if source and destination were swapped?
I've tried to read many of the topics in this forum first and tried to find a solution to my problem, but can't find one.I'm testing CentOS 5.5, it's the first time I'm using a CentOS Linux release.I'm trying to configure the proxy "client side " on it and cannot find how to do it.On other Linux release I've used the ENV variable like "http_proxy" or "HTTP_PROXY" etc etc.This time, I don't know why but it doesn't work.I've put the name and @ip of the proxy in /etc/hosts and tried different version upper/lowercase of "http_proxy" "HTTP_proxy" "ftp_pr.." but it doesn't work.If I configure manually Firefox and puting the name or @ip of the proxy we have on our network, it works.But if I try to use ENV variable it doesn't work...
defining keyboard layouts in linux (ubuntu 10.04 here). there does not seem to be any easy, graphical way to define keyboard mappings (except for keyboardlayouteditor, but frankly, i do not understand the installation description.i am using an apple aluminum keyboard with a german layout, but no matter what i do the (<>) and (^°) keys are always swapped (i did manage to change the default behavior for the f1...f12 keys from multimedia back to 'ordinary', application-centric... all you have to do is add the line echo 2 > /sys/module/hid_apple/parameters/fnmode to /etc/rc.local... this is so bloody obvious i am ashamed i had to search the web for this!).
adding to my distress, i find the chinese IMEs a horror (not a single one of the many i tried does anywhere come near google pinyin for windows), and have gotten neither ibus nor scime to work in a satisfactory way for me. i find linux keyboard handling a morass. i know this must be one of the hardest problems in computer science, since this subject gets so convoluted no matter whether its on windows or in-the-browser javascript. as a linguist i am well aware of the inherent complications proper text handling poses, but looking at descriptions how to configure xkb makes building interstellar spaceships look like a cakewalk.
find a place in the system where keystrokes are recorded;read out those codes (could be scan codes or character codes) using a daemon (implemented in python; i heard you have to listen to IOCTL or somesuch); when certain code combinations appear, switch them to do what you want;applications now get to see a X where formerly the got to see a U and vice versa;profit!
Is there a place, in ubuntu / linux systems that does allow reading out keyboard codes? Is there a way to block processing of such keyboard actions until an intercepting daemon has processed them? Would such an interceptor work for a broad range of use cases? like on the command line, in a gtk app, in wine, in firefox and so on? An alternative would actually be to grok keyboardlayouteditor, so if someone could post about a readable, complete installation instruction or point out installable packages, that'd be great, too.
I've been trying to make myself anonymous, but I cant find 'Tor' anywhere, tried 'yum & kpackagekit' neither have it. I did find 'Privoxy', installed it, set proxy for HTTP and HTTPS in Firefox, but it says 'unknown proxy' when I try to use it! I've been to the Privoxy web site and read through the 'User manual', but most of it is 'geek' to me!
Currently my DHCP Server is working now what i want to have is auto detection of squid proxy in any browser but I still got an error in my dhcp server when I restart it.
My Config:
# DHCP configuration generated by Firestarter ddns-update-style interim; ignore client-updates;
I am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?
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?
At the moment I have a proxy and all the users have to configure it in the browser to access internet. I want to make the users able to browse even without configuring the proxy in the browser. but eventually it should be received in the proxy rather than giving an error to the user. I heard with transparent proxy I can redirect all the traffic from a particular network, to a particular host( ie my existing proxy).
I tried this using firewall rules. But then the existing proxy doesn't understand the protocol of the requests. I heard that it should be in the kind of proxy protocol.
i have run a ftp server with vsftpd. i set a public ip address on my server . but i want to define a name for this ip address (for example ftp.test.com) how can i do that?
Alsamixer is better now since one can press F6 to select the card and tune it. but well, ok, when one has several cards, if you have a mic, alsamixer is not bright and select it as first card, so one resutls into no sounds.OK, alsamixer is nice, but man, how to select a specific card and select it as defautl. Then at reboot, I wish to have sound. Is that possible with Linux or shall we wait a stable version of Debian whcih works, simply ?
I installed Redhat linux 5 on my laptop .. after installation i the OS did not detect the network driver ... i downloaded the driver of that NIC but i dont how to install it
I was wondering how could I specify for how long the logs will be kept. Rsyslog doesn't have such an option (at least I didn't find it).Do I have to use logrotate for this, or is there some other option?
