What port needs to be allowed/opened on the server side to allow Fedora 12 to access files on the server via NFS? My email and internet through the server work fine, but NFS file sharing/browsing does not work and I'm not having luck with forum and google searches finding what needs to be changed.
Fedora 12KDE, 32bit, install from liveCD, fully updated as of this date.
I want to do a simple port redirect, i.e. whatever comes trough whatever interface on port AAAA will get redirected to port BBBBI thought that iptables -t nat -I PREROUTING --source 0/0 --destination 0/0 -p tcp --dport AAAA -j REDIRECT --to-ports BBBBhowever it doesn't work, e.g. nc -v -w2 -z localhost AAAA gives:
nc: connect to localhost port AAAA (tcp) failed: Connection refused
while
nc -v -w2 -z localhost BBBB

Now that I've set up an FTP server here at home I'm thinking that it might be a good idea to change from the default Port 21 to something else. Can I use any port I desire or are there only certain ports that support this protocol?
View 14 Replies View RelatedI am setting up Apache (Fedora 12) inside my home network. From inside my home network I access it without any problem. I need to set it up to access it from internet. I have the following questions. Here is temporary setup for testing purpose.
Internet-->ADSL modem (SEIMENS Speed Stream 4200)---> Apache (Fedora 12)
1. Do I have to do any kind of ports forwarding on ADSL modem. (There is no option to do port forwarding on Modem) May be I need different Model of Modem??
2. I tired to Ping my real IP for modem form another computer from internet. I am even unable to PING the ADSL 's real IP. Why it is that?

I installed ZTE MF 626 modem in my F10 with kernel 2.6.27.12-170, i run usb_modeswitch and so far things happened normally. Watching through /var/log/messages it says that F10 detects two port device for this modem: ttyUSB1 and ttyUSB2, and in the sequence it disable port ttyUSB1 BUT Network Manager still set this port.I mean, when i connect via wvdial appointing to ttyUSB2 i get connection, but Network Manager fails to do it appointing to ttyUSB1. How to change device port in Network Manager?
View 1 Replies View RelatedI have two PC's, one with slackware and one with arch, and I am trying to access the web server from the archlinux machine but i haven't manage to do that. The archlinux machine is connect to the internet via the slackware machine via a crossover cable:
internet > eth0 (pc1) and ppp0 (the PPPoE connection, pc1) > eth1 (pc1) > eth0 (pc2)
PC1:
ifconfig eth1 192.168.0.1 netmask 255.255.255.0
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -i ppp0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth1 -o ppp0 -j ACCEPT
pc2:
ifconfig eth0 192.168.0.2 netmask 255.255.255.0
ifconfig eth0 up
route add default gw 192.168.0.1 eth0
/etc/resolv.conf (The same DNS as the first PC)
And now the internet is working and on the archlinux machine, but I am not able to access the web server from LAN with a public IP. I tried many iptables port forwarding commands but none worked.
This should be easy but for some reason its not working. I don't have admin rights on one of my local networks to open the firewall for port 80 to make my server accessible remotely (from the internet). I have a remote server (OpenVZ VPS) and I want to port forward so that [url]:8080 will point to my localhost:80 from the internet itself (i can get it to work on the remote VPS server's local network)...
How could I accomplish this? Basically, I am trying to serve webpages from behind a firewall using a VPS as a hub.
I'm trying to set up my own mumble server, but I don't want to use the default port 64738, for security reasons. I've tried changing the lines:
Code:
# Port to bind TCP and UDP sockets to
port=64738
in the /etc/mumble-server.ini file to a port of my own choosing. However, it won't work unless I use port 64738. Is there anything I can do about this? Do I perhaps need to change something in ice (whatever that is)?
I want to run a proxy server on port 1080, so I typed
Code:
ssh localhost -D 1080

What can I do so that other clients can connect to port 1080 on my server?
Here's my (admittedly complex) situation:
I set up a dynamic DNS address for my home network. Let's call it [URL]. Then I set up one of my machines with a bind9 DNS server and pointed my router's DNS setting to it. I did this so that I could resolve awesome.server.com from machines inside my network and have them correctly find my server. Then I set up a second machine to serve web pages using [URL]. I did this by forwarding port 9200 on my router to port 80 on that machine. This works, but of course, it only works from outside my network.
What is the best way to get [URL] to work from inside my network?
I've tried setting up the iptables on my server to forward that port, but it just times out. I used these rules that I found by searching the internet:
Code:
iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 9200 -j DNAT --to 192.168.0.300:80
iptables -A INPUT -p tcp -m state --state NEW --dport 9200 -i eth1 -j ACCEPT
However, those rules might be failing because they are intended to forward ports requested from outside the network. I must admit, this iptables stuff is way, way over my head. Is there a different method that I must use to make it work inside my network? Or is there a better way besides iptables?
I'm trying to get my SSH server I set up on my home box working from behind a router. A 2wire 2700HG-B gateway, in fact. Now, I know my server is working fine, because I can get into it via loopback, anywhere inside the LAN from another machine, OR if I go into the router's config and enable DMZ for the machine. However, I don't like having DMZ on all the time because of the kludge-ness of it, and the security issue of the complete absence of a hardware firewall.If I try to port forward and access it from outside the LAN using the external IP (or my DynDNS, because it's dynamic), it just times out. I have a nonstandard port (45) for the listen port of the server, to keep away hack attempts if I were using the standard 22. I used this to see if the port was open, and it said it was. But, I tried the trick of telnetting the IP with that port, and it also timed out, instead of printing stuff about OpenSSH.
Attached is a screenie of my router's firewall page, so you all can look at it and see if I'm an idiot and doing it wrong. You might notice uTorrent there, it's because this machine is a dual-boot with 7, and the router doesn't differentiate the OS's. Also the SSH @ 46 port is for the Windows side, with freeSSHd. I changed the port on that one so the client I have can distinguish them, so it can run a reachability test.
Wow, don't know why I seem to have so much trouble with this ftp stuff. I have so start all over a few times, reinstalling Lucid Lynx destop all over, and adding the needed files to make it a server. I am just trying to do something simple for now- just having a localhost server environment to develop my joomla website, and later on host it from my server 'out there' (I already have a domain name and dynDNS service with nameservers etc. but don't want to do that yet, as I have in the past with my router forwarding port 80, and actually got hacked! so I don't want to do that again until I learn more about security) My problem right now is that I can't even get the localhost ftp to 'connect to the server'. i know the host name (localhost) and username/password that I set when I set up Lucid Lynx, and I'm sure that is what I use for the ftp usernamepassword, host etc. And I put port 21 for the port. I see from 'Shields Up' that my port 21 is closed. So I followed advice on a thread and entered a few commands in the terminal to ad iptables etc. But still, port 21 is closed and I can't install components with the Joomla installer in admin's backend. And I can't use fireftp to even change permissions in my local folders. What do i do next, open port 21 somehow? I saw a terminal command about opening port 21 that was simple but I forget it.
View 2 Replies View RelatedI 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.
VERY 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.
If I forward port 80 to port 3128 for squid with an iptable rule, does port 3128 have to be open on the firewall or is this all routed behind the firewall?
View 4 Replies View RelatedI'm trying to enable port forwarding so I can use my computer as an FTP server to some friends. Here's my setup:
CLEAR wireless modem <--> LAN port 4 on router (not WAN) and LAN port 1 on router <---> eth0 in Ubuntu 9.10
The modem acts as a DHCP server which successfully assigns an IP address to my desktop system. I can also go onto the internet just fine on my desktop, and any other computer that connects to the router.
I have enabled port forwarding on the modem (not the router because it's being used as a switch, and not using its WAN port) to forward ports 21 and 80 to my desktop. What I don't understand, though, is that when I try to FTP to the modem's WAN IP address, the connection is refused. However, when I use websites such as:
www.canyouseeme.org
www.yougetsignal.com/tools/open-ports/
They say ports 21 and 80 are open (and not other random ports like 22 or 23 which I tried to see if the site simply said everything was open) but I cannot access my site from a web browser.
I was wondering what it was that's stopping computers from the Internet from communicating with my computer? The modem? The router? Configs?
I am using Ubuntu 10.04 Lucid and VMware 2.0 server. I have a an XP virtual machine that is needed for work. When I am at home and I place my cat 5 cable to my cisco catalyst switch, my XP VM recognizes the ethernet card on my laptop and bridges fine with ubuntu and works fine and I can get to my network. When I take my laptop to work and I go to a site and I plug it into a World Wide Packet 311 management port on the switch, my XP Virtual Machine does not see the network no matter what setting I set it too(100 full, 10 full, 10 half and etc). It simply says that the network card is disconnect. Ubuntu see the network fine and I can ping and talk to the network without any issues but the VM does not.

I am currently having an issue attempting to set up a dedicated server for source games (TF2, CS:S, L4D2). The required port (27015), along with most others, appears closed to the rest of the world and upon a port scan with DMZ hosting on (therefore no router interference between the internet and my computer) only a few ports are open (80, 139, 443, 445). My ISP does not block ports so therefore the only issue I can find is with my computer running Ubuntu 11.04. I have ensured that all traffic is allowed via iptables and I can't think of anything else that would have ports closed.
