I used Avast webfilter (proxied webtraffic through Avast) when running Windows. Sometimes Avast would alert and "protect" me from being infected by a compromised website. NOTE: Avast would alert even absent clicking any links. Just viewing the page could result in infection. Should I be running some kind of proxy webfilter for protection? My understanding is that Firefox can be compromised and this can in turn compromise Ubuntu.Are these kinds of threats specific to Windows running Firefox, or Firefox per se. If Firefox per se it seems like I need some sort of Proxy webfiltering like Avast provides.

I am getting this error "Unknown filter "police", hence option "rate" is unparsable. This is in Linux Kernel 2.6 which is compiled with the "policing" option enabled in Qos (Kernel config). The error seems to be coming from the file tc.c in iproute2/
static int parse_nofopt(struct filter_util *qu, char *fhandle, int argc, char **argv, struct nlmsghdr *n) {
__u32 handle;
if (argc) {
fprintf(stderr, "Unknown filter "%s", hence option "%s" is unparsable
", qu->id, *argv);
return -1;
} if (fhandle) {
struct tcmsg *t = NLMSG_DATA(n);
if (get_u32(&handle, fhandle, 16)) {
fprintf(stderr, "Unparsable filter ID "%s"
", fhandle);
return -1; }
t->tcm_handle = handle; }
return 0; }
This is called from get_filter_kind() which is called from tc_filter_modify(), called from do_filter(), from do_cmd() from main()...all in tc.c. Is this a known "bug" in iproute2+2.6 as the 2.4 Kernel works with the same settings?
I am trying to do sudo add-apt-repository ppa:freenx-team from behind a proxy. Issuing export from the terminal gives
declare -x ftp_proxy="ftp://proxy.acme.com:80/"
declare -x http_proxy="http://proxy.acme.com:80"
declare -x https_proxy="http://proxy.acme.com:80"
which is the correct proxy for my company (and works elsewhere) however the add-apt-repository fails with Error reading https://launchpad.net/api/1.0/~freen.../+archive/ppa: <urlopen error [Errno 113] No route to host> This same action works correctly from my home machine that is not behind a proxy.

View 6 Replies View RelatedI'm running a squid server on debian lenny with ntlm_auth.
Everything is working good after following those two tutorials : [url] and [url]
As all was working perfectly i decided to rebbot my server, and after reboot the ntlm-auth was not working anymore.
When i tried to run the command "wbinfo" with many options i had this error message "error looking up domain users" or"error looking up domain group" so i think that the problem deals with winbind module.
I know that proxy user needs rights and that after reboot the rights are reseted, so this problem doesn't come from here.
And when i try to open IE with a client i have this "cache accesss denied" because the ntlm_auth wasn't done.
I tried to restart all services (samba,winbind,squid) without any success, only the "kinit" command is still working...
What is going on with winbind when the server is rebooted ?
is it true that mock can't work behind proxy?

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'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.
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.
