For some reason I can only access FTP on my Ubuntu machine in my house. I have a number of apps running on it including FTP (port 21), mt-daapd (port 3689) and Confluence (port 8080). I have these ports forwarded in my router configuration and have verified that they are open with this service: [URL]. For some reason I can only access FTP from the WAN. I can access everything from the LAN. I have tried for hours but can't figure this out. I tried adding 'Listen 8080' to my ports.conf file but then apache spit out this message:
$ sudo /etc/init.d/apache2 restart
* Restarting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
I'm trying to set rxtxSerial to work so a Java app has access to a serial port (via SiLabs CP210x driver, port /dev/ttyUSB0). When I use update-alternatives --config java, there are 3 alternatives which provide `java'. I have tried openJDK and Sun. Both fail but with completely different messages.
how to access networking port and run scripts on that port so as to gain access of remote machine.is that possible through command prompt or through software.
i kno ip address of my frnd who is chattin with me .okay.i want to run an application on his computer .i came to kno tht we can run script o through port
ive been looking through several online documents and forum posts but i cant get a clearcut answer on how to set up serial port acces in ubuntu 10.04 (server).
I changed to a 4 port ethernet router (D-Link DSL-2542B Adsl2+)with intention to share Internet access with my brother (he's on Vista).Initially it all went well,but 3 days ago there were connection problems occured on the part of the ISP. Without realized the problem,I had reset the router.This morning I've been informed by the ISP that the connection has been re-established.So,I accessed the Internet via the 4 port router but failed to do so (server not found).Suspecting that the problem was from the 4 port router,I reverted to my old Adsl router (DSL-520B single port) and without any problem I managed to access the Internet back.I really need help to configure back the 4 port ethernet router to its initial state.
I have a newer Belkin N+ router that has a USB port for accessing an external hard drive.I can access the HD with no problem in Windows.I am new to Linux/Ubuntu and cant seem to connect to the HD. In "Network" I have a folder "Windows Share" and within that folder is where I see the HD "CBHD" (name of my drive). I cant click it because when I do, i get an error message along the lines of (cant remember exactly right now) "Failed to mound"I typically access the drive in Windows via : \192.168.2.1
My program tries to open serial port on Fedora 12, and shows "Access denied" on Open Port operation. The same program runs successfully with root rights. What can I do to get COM port access as regular user?
I work for a company who has a really closed proxy configuration, and I think that only the port 80 is opened, but with a lot of blocked sites.
I guess that for other cases, like bank sites and others, they opened the 443 port too. But other ports are all closed.
I set up a linux server at home, and I need to access it with SSH. However, I can't access my server directly by its IP number,
I don't know why, but probably it's because some rule in the company's firewall or proxy, right? What I did to trick this was create an account on NO-IP.org, which provides me with a DNS to my host. In this moment, my "network" is something like this:
When I try to connect (by my work PC) with "telnet xxxxx.no-ip.org 80", or with Putty, I get a blank screen, no errors, no nothing.
But when I try to do this on another PC, on another network without proxies, I'm successfull. So I really think that is my company proxy thats blocking this way, am I correct?
So I think that the solution for my problem is to create a tunnel, to transport my SSH connection over an HTTP, through the Port 80.
But is there a way to do this?
It would be something like this:
Is that correct?
If so, how could I do this?
I'm trying for a week now, with programs like http-tunnel, proxy-tunnel, and others. But nothing until now.
So, any ideias how could I could communicate my SSH client at work over a HTTP (port 80) connection, over NO-IP, my modem, my server, HTTP to SSH, and finally my SSH server?
was wondering if there is an alternative method to using udev rules in order to get access to the USB serial ports. Is there a command to check the names and give them to you? I'm looking for something along the lines of "ttyUSB".
It was yum installed and all went well without error but I'm not able to access bind on port 53. Selinux is disabled for this test, and the iptables have been saved to the below config in the INPUT chain:
Code: target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT udp -- anywhere anywhere udp dpt:domain state NEW
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
I have a vps server running certain services which can be accessed via a web browser (e.g webmin control panel), but I have recently been unable to access these services from my home machine using Firefox 5.0, running ubuntu 11.04.
Example:
I can access the server on port 80 fine, eg: [URL]
However I cannot access my webmin control panel on: [URL]
The pages takes ages to load and then times out. Same with transmission-daemon on: [URL]
Everything is set up fine on my server, the ports are open in firewall etc. and I can access these pages fine from my work computer.
This has only started happening in the last day or two and had been working fine up till then. I have not messed around at all with the firewall on my home machine. I have tried other browsers besides Firefox with same result.
I'm curious is it possible to access your router settings. I'm trying to open up a port. I have done this in my firewall now I need to open up my port through my router. I'm using fedora 15.
I have a WRTG54S Linksys router and Fedora 11 on my Asus EeePC and I would like to be able to access my Fedora remotely via ssh however I'm not sure which info and were do I need to change it in my router, also I want to be able to change the ssh port access is it from /etc/sshd_config ? My internet connection at home is via cable modem and with a connection that is always on. (no dialer)
So this is my first post so I'll put it in "Newbie".I seem to have successfully configged my httpd.conf file to listen on port 8008. I restarted httpd ok. However, when I go to port 8008 in a web browser from another computer on the internal network by going to 192.168.2.5:8008, it doesn't connect. When listening on port 80, I can browse to the IP address fine. is this a server-side or client-side issue? Using Fedora 12. Thanks in advance and tell me what forum this would best fit in.
I tried changing the sftpserver port but its not working, besides how can i restrict users from particular ips.Eg: users a can ssh from 192.168.*.*user b can sftp from 200.*.*
I have a usb port problem. I am trying to set up printers to usb port. When II have setup printer to connect to usb. When I test connection, it prints. Any other part of printer setup, shows up in the Que, but will not test print.Seem that my usb port does not have permissions set up properly. How do I set up permissions and keep them setup?
Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.
Iam using snmp to access the remote system data.But according to the requirement iam encoding the snmp request data to OAMPDU packet format and sending to remote system.the remote system receives the OAMPDU packet,decodes it and is sending the snmp packet to snmp agent through UDP socket which is bind to port 161.but iam unable to receive the response from snmp agent.i have created a udp socket which is bind to 161 port to receive the response.
if i use any other free port number other than 161 for receiving snmp agent is not sending the response to that port.can any one please suggest me how to overcome this problem.Can we configure the different ports for tx,rx ?How do we know on which port does snmp sends the response ???
I am running a VPS of CentOS. clock command doesn't work.[174-37-247-102.lx-vs.net ~]# clock hwclock is unable to get I/O port access: the iopl(3) call failed. How to solve the problem? I have tried "timeconfig" and set to New York and System Clock uses UTC and restart the server but it was not useful.
I am having trouble getting my FC10 with tomcat visible to the outside world. first off i am somewhat new to linux. I am running vmware workstation to host my linux web server. i have my VMWare setup to use my second NIC solely. it is bridged and the tcp/ip is disable from the host. i can ping the ip address but cant access tomcat on port 8080 from the outside. i can hit it fine from inside fedora. i have configured my router (wrt54gs with DD-WRT firmware) for port forwarding. so basically i think that the problem is somewhere in between the host and the vmware configuring allowing the port to be forwarded through.
I am trying to make my home server accessible to the whole web. I have installed Nginx on my Fedora 15 64-bit Linux machine, and it works with localhost but it doesn't work online or allow other computers on the network to access it via the IP address. It keeps coming back with: Could not connect
I have port forwarding. I have even tried different ports but they all seem to be blocked. What could be wrong? I have a netgear router.
Been a while since I last posted here, though I stop by often. Unfortunately I find myself in a bit of a pickle again. Here's the situation. I have an RHEL3u5 server running Apache 2.0.48 and an equivalent of Tomcat and JBoss. IBM's WebSphere Application Server 6.0.2 to be exact, the Apache also being one of their flavors (IBMIHS).
Everything's been going dandy since forever, but lately the httpd processes seemingly just hit a brick wall of some unknown kind. Checking the /server-status page reveals a whole lot of piling up "waits".
The funny part is that the load average rarely goes higher than 1.0, I/O seems within limits, memory usage as far as I can tell seems fine, disk usage appears all good... I would've felt more at ease if something did shoot through the roof, but there's just nothing to go on. It's definitely Apache getting its knickers all in a twist as well since I can access the servlet engine's web GUI just fine over its dedicated port via browser.
Here's what I noticed so far: Apache processes rise steadily to over 35 or so, after which it all goes south fast. As a result and as a temporary fix, I've enabled a cronjob that checks the amount of httpd processes and just restarts Apache if they're above 28. So far this seems to keep things sort of happy, but obviously I'm still twitchy with the overall state of affairs. I do not have the settings immediately at hand, but here are some further details so far:
Server spec: 8 x Xeon CPUs 8GB RAM
I'll post further details probably on Monday, specifically key portions of the httpd.conf file.
I have a mail server i need it to send message via port 587 not port 25, i make some changes to my postfix server which i use and it is already successed making a telnet to 587 port like it :
I only began using Linux with the release of FC8. I've upgraded into every new version (upgrade, no clean installs), after the new versions had been out a while. I struggle with command lines, updates, cups and other very cool tools that are only difficult because they have so many options. I'm Windows guy at work, a system admin and db administrator, plus the company expert on Excel. But, all in all, I hate Windows, and I'm loving Fedora, even if I struggle.
This last upgrade really kicked me in the pants. The first thing I noticed was all of my software sources were gone. I did some research around the forum and tried a few things, but it's still not working. Unfortunately, I may have uninstalled Yum in the process, but not rpm. I've tried to re-install the yum packages, but still no luck.
This morning before leaving for work I noticed that a boot log indicated that cups had failed. I went in to restart the service (through gui) and it said it was running. So I stopped the service and re-started. I tried to access port 631 through Firefox and it wouldn't open. I need to check the firewall to see if it's an open port, but beyond that I don't know.
Now I'm wondering if I should just do a clean install. I haven't done this, mainly because I didn't want to hassle with setting up my printer again (although, it's a Brother and they have the drivers and good instructions), and I didn't want to lose any emails that I've received via Thunderbird. The printer is really a non-issue now, as I'll have to set it up anyway. I have a backup of the /usr folder and all the documents. Question is, if I restore the Thunderbird folder after a clean install, would it bring back my email?
I'm trying to limit access to port 8443 on our server to 2 specific IP addresses. For some reason, access is still being allowed even though I drop all packets that aren't from the named IP addresses. The default policy is ACCEPT on the INPUT chain and this is how we want to keep it for various reasons I wont get into here. Here's the output from iptables -vnL
[Code]...
Note the actual IP we are using is masked here with 123.123.123.123. Until I can get everything working properly, we're only allowing access from 1 IP instead of 2. We can add the other one once it all works right. I haven't worked with iptables very much. So I'm quite confused about why packets matching the DROP criteria are still being allowed.
