Can't seem to access my squid server on port 80. I have port 80 allowed in the conf for this IP. apache is listening to port 80 but only on the 2nd IP. iptables is allowing through port 80 incoming nmap shows no ports open on 80 though:

I've killed apache via /etc/init.d/apache2 stop, but something is still listening on port 80:
Code:

How do I find out that program this is?, or how to I stop it listening?
When I use the following command:
ssh user@ssh_server -L 5500:localhost:5500 -p 22
everything works fine. I can log in, and local port forwarding is done. Otherwise when I use the command:
ssh user@ssh_server -R 5500:localhost:5500 -p 22
I get an error "remote port forwarding failed for listen port 5500". However when I try remote port forwarding in WinXP by use of putty there is no problem...
I make an application on GNU/Linux which listening on a MULTICAST stream, so I open my unconnected socket, bind it on a MULTICAST address and a port, join the multicast group with the "setsockopt (IP_ADD_MEMBERSHIP)", then I receive datagram on my socket.
Now I've two different instances of the same application that run with their own MULTICAST address and port. And what I found strange is that, after a misconfiguration, I switch the ports, for example:
Emitting on 225.0.0.1/23451 and 225.0.0.2/23452
Receiving on 225.0.0.1/23452 and 225.0.0.2/23451
And my receiving part doesn't care about the MULTICAST address, it looks like the socket is listening on the port number only! I mean that the receiver [225.0.0.1/23452] take its datagrams from emitter [225.0.0.2/23452] and vice-versa!
I just installed KVM on a new system and just found out the hard way that virt-manager cannot be installed on the same machine because of a library conflict, so I will have to manage my VMs from another machine. I will use a SSH tunnel to forward the port, but I don't know what it is. Also, how do I start KVM?

View 3 Replies View RelatedIt appears that X Windows under Ubuntu (or Gnome?) is started to listen to a Unix named socket, instead of a TCP port number, for client connections. That's what SSH is forwarding when it does X forwarding. I need to start X applications on a remote machine, and then close the SSH connection. So I need to make the connections directly. This is within a LAN on private IPs, so security is not an issue. I searched on help.ubuntu, but there appears to be no particular document that covers this. Anyone know where this is configured to enable it to listen on a TCP port like the usual 6000?
View 6 Replies View RelatedI wish to use the VNC server built in to the Ubuntu to easily access it from other computers on my local network. I need to skew the VNC Server port off of the normal 5900 to something else because I am using VNC to access several computers (sometimes simultaneously) so each VNC server needs to be set with a different port #. At this point it is all local subnet connections with no incoming internet access and I am not worried about security.

View 1 Replies View RelatedOn Fedora 13 is there anywhere else on the system that I have to change to get Apache to Listen to an assigned port, something other than 80. Suppose for instance I wanted Apache to Listen on port 94. I told by the site that their router is forwarding apache to port 94. That doesn't mean I change the Listen in httpd.conf. correct. Apache is still expecting connection on port 80 but in this case 80 then gets forwarded in the router to 94. This is my understanding.

View 3 Replies View RelatedI have just installed Squid proxy. i also use WPAD to deploy policies for all client. Both works well together. Now i want to configure firewall Juniper SSG140 will be deny all request from client to access internet and redirect to Squid. I mean deny HTTP & HTTPS except Squid (port 3128), even i want to all access to internet have to through Squid proxy. I don't expert about the firewall Juniper. May i know step by step configure it.

I was just wondering what I have to edit in order to get Maia Mailguard to listen on port 443 instead of port 80
right now I am logging on with [URL] but I would like to connect to [URL]
i've got a software that uses a specific tcp port e.g 11111. i want to redirect all the traffic from 11111 to squid port 3128. i'm using the following commands to redirecting:
iptables -t nat -A PREROUTING -p tcp -m tcp -i eth0 --dport 11111 -j DNAT --to 192.168.0.1:3128
iptables -A FORWARD -p tcp -m tcp -i eth0 --dport 11111 -j ACCEPT
my ubuntu server has two interfaces. eth0 is for local network (dhcp assigns ips) and eth1 is for internet. my ubuntu server acts as a gateway and as an authentication server for users.
at squid also i have the following configuration regarding my port:
acl myport port 11111 http_access allow CONNECT myport. my squid installation is not transparent as users need to authenticate in order to access the web.
my application is a windows application and of course is not working. i examined the packets with wireshark and i noticed that when the program tries to access the internet, squid replies with err_invalid_request (the packet contains that data). the program is trying to send some plain text via port 11111 and as far as i can image, somehow squid declines the data. i cant get rid off squid as i want to pass the traffic from squid. what is the problem?
I have been working in Linux for the past two years.And working in squid for the past 6 months.The following is my Setup
ETH1 - ISP1 (Active)
ETH2 - LAN (Active)
ETH3 - ISP2 (Inactive)
Using Iptables I forward 80 port through squid (3128).Other ports just get connected in the proxy machine itself since it has IP_FORWARD enabled. All my client machines browsers enabled with "Use proxy 3128". I just want to make all the port to pass through squid server.
I have got a reverse proxy that is working just fine, it accepts requests on port 443 and port 80 and ONLY sends traffic upstream to port 80 to the apache server listening on localhost. I use the following config:
https_port 10.14.1.72:443 cert=/etc/squid/self_certs/site.crt key=/etc/squid/self_certs/site.key defaultsite=site vhost
cache_peer 127.0.0.1 parent 443 80 no-query originserver login=PASS
http_port 10.14.1.72:80 vhost
My problem is the following : The site should act differently in some occasions based on whether http or https was requested. So my idea is to setup second http vhost on apache listening to port 8080 and on that vhost I would server the https code. So is it possible to use SQUID to :
Send traffic destined for port 443 to localhost:8080
and
Send traffic destined for port 80 to localhost:80 ?
I'm trying to get https/443 traffic go through squid.

I am using squid to controlling access to the internet all is working fine expect one of the user who is using outside organization portal to connect internet. But whenever he tries to enter in the portal by typing (EXAMPLE)url. Permission denied error from squid occur.
How can i allow this portal in squid. So squid will allow this to access.

Client unable to listen to NIS domain server.I have configured an NIS server, which is working fine.I then configured an NIS client to share some like passwd, shadow, etc.By default the client was trying to communicate to the NIS server using the broadcast method..However if I restart the client computer, it fails to communicate or Listen to the domain server. Once I login to the pc, I then check the /etc/yp.conf file and it switched back to the broadcast method.Is there any way that I can make this entry: domain naman.com server station51.naman.com permanent so that even after the reboot it should communicate using the client-server connection rather than the broadcast connection.
View 8 Replies View RelatedVERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.
