Ubuntu :: Connecting Being Refused On Home FTP?
Dec 3, 2010
as a personal project for this weekend I told myself I was going to finally get my home FTP server set up and running; not a hard task (I assumed) but one that I had been putting off for a while. Now to the nitty gritty details installed vsftpd, editted the config file to what it is now (Below) Anonymous users are disabled, local is enabled, port is set to 21, restricted to home folder, made an exception in gufw's firewall config. Went to my router, (its a dlink DIR-628), just so happens there is a nice "Virtual Server" section, specifically for home webserver / ftp's.
Public Port: 21
Private Port: 0 (Default)
Name: FTP
Internal IP (That everything should be sending to) 192.168.0.198
Protocol: TCP

I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

I have a home server that I have setup to connect to via SSH. All is working well with that. I would like to have the home server access the internet through a VPN. However, if I do this, I am no longer able to connect to the server via SSH, even though I know what its IP address is.

I have a beefy Win Box desktop that i'm using as a media server and i have a home network setup already using windows xp. I had everything running fine and the PC connects flawlessly to my Bravia TV and both my ps3's so i know the network and sharing settings are setup just fine. Anyways i got tired of all the Windows 7 BS and decided i would once again use Ubuntu on my Toshiba netbook. So the question is how in the heck do i get my Ubuntu netbook to connect to the Desktop? I've tried browsing the fourms but either i'm missing something of just a little slow. What "extensions" would i need to get and how would i go about implementing it from there?

Is it possible to SSH to a remote computer from within an SSH session? I'm connecting to my home server via SSH, and trying to connect out to my VPS. I know the key.ppk file works, as I can use it to connect directly from my PC. The output I'm getting is shown below:
Code:
# ssh -i key.ppk -v -l myuser myuser@domain.co.uk
(tried various ways of doing this)
Code:
OpenSSH_4.6p1 Debian-5ubuntu0.1, OpenSSL 0.9.8g 19 Oct 2007
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to mydomain.co.uk [123.456.789.012] port 22.

debug1: permanently_set_uid: 0/0 .....
debug1: PEM_read_PrivateKey failed
debug1: read PEM private key done: type <unknown>
debug1: No more authentication methods to try.
Permission denied (publickey).
There's nothing I can see in the auth.log file on the VPS.

I recently switched a computer running PCLinuxOS over to Fedora 12. I used to have PCLinuxOS set up as an SSH server so that I could quickly and easily share files with other computers in the house. Since the switch, other computers cannot connect to the SSH server unless I use sudo. I cannot set up a network connection in the GUI; "Unable to connect to server. Please check your settings and try again". Same thing happens if I use the ssh command without sudo. Is Fedora blocking something?

I've searched all night for similar threads and either don't understand the instructions or find that my computer simply isn't the same! I've tried to gather as much information as I felt needed when people asked in other threads. Just use small words around me, I'm really *that* technologically inadequet. Why I bought a linux ubuntu computer is still a mystery!
I'm having trouble connecting to my home's wireless internet, which is linksys. I can connect via wire just fine, but I want to access my built-in wireless card. How do I set up the wireless for this machine? Here's the info of what version of Ubuntu and about the card.
Ubuntu 8.04.1
l
Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E PCI Express Fast Ethernet controller [10ec:8136] (rev 02) Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)
What do I do with this information? If I could transfer edible cookies through this computer, I totally would.

I've just installed openSUSE 11.3 for the first time on a Dell E1505 notebook and am having problems connecting to my home wireless network. Using the Network Manager I've been able to find my home network and connect after entering the network password. After a minute or two the wireless network is still shown as active but their is no connection (websites will not load).
I'm completely new to Linux so I have almost no clue what could be causing this. I have tried connecting the notebook hardwired (Ethernet) to the router and get a perfect connection if that information helps any.

I might as well start off by saying that I have the Linux-based Linksys WRT54GL router running the Tomato firmware. I've come up with an idea that I'm not sure is possible. Specifically, setting a router up to ban not by the MAC address of the network card, but by the operating system the machine itself is running.
This way someone could have, say, a laptop dual-booting Windows and Linux and would be unable to access the internal network if they are in Windows. However, if they reboot into Linux (or practically any other OS) they would be able to access the local network safely without the chance of spreading worms and whatever else garbage across the internal network. Similarly, other devices like Xbox 360s, Wiis, etc. would be unaffected since they don't run Windows. [Yes, 360 probably runs some highly modified NT kernel, but almost nothing else is similar to a Windows PC and the whole system is highly locked down by Microsoft, so I'd say it could be an exception.]
I was thinking of specifically banning Windows XP and lower (honestly as f***ed up as I've seen Vista and 7 get, I would consider banning those too...). The idea is to allow, well... everything that isn't Windows (except possibly Win7) to connect wirelessly to the local network.
Unfortunately, I cannot do anything like this just yet, and I'm in the planning stages, trying to figure out if it is even possible. There are unfortunately two computers in the house that aren't mine (one running Windows XP and another Windows 7... go figure, they came with it and either my sister refuses to use anything else or my mom's computer's wireless is a massive PITA to get to work in anything *besides* Windows). My guess is that this is either not possible or would be extremely hard to pull off. What do you guys think?
On the other hand, it would probably be possible to connect two routers to the incoming cable connection, giving them both different settings (SSIDs, WPA passwords, etc.) and only giving Windows users access to the outer router, but it'd be cool to be able to accomplish something like this with one router through its settings.

Currently my office use a Cisco Firewall which will only allow the ANYCONNECT utility to do the vpn connection. I found a Linux utility (OpenConnect) which will do the same thing, but allow me more flexibility with my networking needs.What I ultimately would like to have is to have a switch that I can connect any network device into it and be connected to the office. IE (my IP Work Phone and Computer) Currently I have is a computer with fedora 13 and two network cards eth0 (home network - connected to a router) and eth1 which I would like to connect a switch to. OpenConnect communicates fine and I can see the work network from the Fedora machine. It creates a vpn0 tun/tap device and I don't know how to pass communication to/from the eth1 device.
Do I try to iptables the ports for the phone and services I need on the computer? Or do I build bridge; and If I do what am I bridging. I have tried making a bridge from eth1 to vpn0 which reply's with unsupported device or something like that.Unfortunately my network skills are bit limited and my office says "it can't be done". Their solution is for me to buy a ASA5505 (or something device) and have a static IP. I would have to make it work as my router and even then it will only DHCP 10 ip addresses; which will cause a shortage of IP addresses in the house.

I have a dual-boot macbook with an OS X partition and an ubuntu partition. When I first installed ubuntu, I changed my home folder to my OS X home directory to synchronize all my files from both. My home directory is now /media/sda2/Users/username/. In a regular home folder, the icons for Documents, Music, Pictures, Movies, etc. are different (not just with emblems, but actually different icons). But when I changed my home folder, these subfolders' icons stayed the same as regular folder icons and I can't figure out a way to change that default setting. I know how to change the icons for each folder manually, but these changes don't appear everywhere (i.e. nautilus, places, etc). Furthermore, every time I change my icon theme, I would have to manually reassign icons for these folders. Is there a way to globally change the folder icons for these folders?

I was previously running 10.04 32bit. Recently upgraded my cpu/ram, so figured I'd try 64 bit. On my previous setup, I had / in one partition, /home in another, plus a few other partitions (/backup, etc).
I did the install of 64 bit, but was too scared to point /home in 64bit to the previous /home. After the install, now all those previous partitions/mounts are on /media. I'd like to just point /home at the previous partition. Should I mess with /etc/fstab to do this or will it cause problems? Is the easiest thing to do reinstall, then point the new install to use the pre-existing /home? Wasn't sure if that would cause problems or not. I've backed up most of the previous /home area, so worst case, if it gets blown away, I should be alright.

I need to specify a different path to home directories on a particular server than what LDAP contains for the users, besides using a symlink. E.g. "/Users/jdoe" vs "/home/jdoe" I don't want to change the actual LDAP attributes, just want a particular server to point them in the right direction (Ubuntu 10.04).
I'm assuming it's something I could probably set in pam configurations?

I've just completed a fresh install of Ubuntu Server (x64) on a HP Proliant N36L. During the installation I selected to install LAMP, SAMBA and SSH. To continue the installation of software on the server I wanted to connect remotely from windows PC on the same LAN. I am using PuTTY but when I try to connect I get "Error:Connection Refused". I have trawled the forums regarding the setup of putty and openssh and everything appears to be correctly configured.I have checked that the services are running on the server and that the IP address for the server is correct.The guides I have read online suggest that ssh should be correctly configured as part of the install, so why can I not connect from the same LAN?Is the firewall enabled by default during install?

recently i made a backup of my home directory in 10.10 before reinstalling 10.10. again.This time I chose to manually define the partitions (50GB Root, 25GB Swap, 325GB Home)Now i wish to migrate the old home into the newly installed home, which is on a separate partition.I have found the following documentation URL...Still, as a beginner I am not quite sure about the necessary steps to perform.As the new home is located on a separate partition is it possible to simple delete all directories there and copy all directories from old home to new home with rsync?
Do I have to install all the software that corresponds to the old home first followed by migrating home or first migrating home followed by installing the software such as thunderbird, Texlive2010 etc.Guess that migration should take place at a later stage. Otherwise my old profile files from firefox and thunderbird will be overwriten by new ones?

Been digging around and not finding anything that quite works.
Background: I had an existing 10.10 install and 10.04 on another partition. When I installed the 10.04 I told it to use the existing /home partition which is also being used by the 10.10 install. All good, both users have directories with all their data in the same /home partition.
Issue: So, as the 10.04 was 32bit (experimenting but another story) I decided I would replace with 10.04 64bit. All went well except when I did the manual partitioning I screwed up and instead of setting the existing /home partition to 'use but don't format' - which I think is what I must have done last time - I left it as 'don't use and don't format'. So, obviously, now the new 10.04 install has its /home inside /, which I don't want. I want it on the existing /home partition as it was with the previous 10.04 install.
Question(s): Is there any simple(ish) way of doing this without a reinstall? Not a major problem as I have only just installed and can do it again without losing anything but time, but I would like to figure out a way to do it without if possible.I want to essentially move the /home/user directory (rather than the /home) and make it /media/home/user inside the existing partition. Seems easy enough on the surface but becomes involved as I investigate.Ubuntu 10.04 minimal install with Xfce DE.

I have installed Ubuntu Lucid Lynx to dual boot with Vista Business on a Toshiba Port�g� R500. Everything seems to be working great out of the box, but I have a problem with available space on the rather modest (but spectacular performance) 64GB SSD.
1) Current Partitions:
Toshiba includes three partitions on the new 64GB system, to which I have added one primary Linux container partition, enclosing two logical partitions.
- /dev/sda1 TOSHIBA SYSTEM VOLUME: 1.6GB, Partition type "Unknown (0x27)
- /dev/sda2 Windows Vista Business: 49GB, NTFS
- /dev/sda3 HDDRECOVERY: 6.5GB, Hidden HPFS/NTFS (0x17)
- /dev/sda4 Linux Container for sda5 & sda6: 7.6GB, Extended
- /dev/sda5 Ubuntu Filesystem: 6.6GB, ext4
- /dev/sda6 Swap Space: 1.0GB, Linux swap
I'm sure I'll remove Vista eventually, but in the meantime, (along with MS Office) it requires a whopping 32GB just to admire itself, after all the updates and security upgrades have been applied. I shrunk the partition to 49GB to leave space for future updates and upgrades.
Right now, Ubuntu only occupies 2.4GB of it's allocated partition, leaving 3.6GB free (I know, that doesn't add up to 6.6GB, but that must be something to do with GiB vs. GB, ... or magic, maybe). Swap is only 1.0GB, with 2.0GB of RAM, but I don't use Hibernate.
2) Installing /Home on SD Card
Well, I tried this first, since I have a nice 8GB, Class 10 SD Card, and a built in SD Card reader. With the SD Card inserted during installation, I was able to select it and designate it as /Home, but when I tried to restart after insallation was complete, I got an error message before the Ubuntu login screen could appear.
I think what is happening is that it doesn't mount normally when booting. It's not listed as a bootable device in BIOS, but there is a Toshiba Bootable SD Card utility included with Windows, which needs a bootable floppy or something to work. There must be something that allows the BIOS to recognize it as a floppy during boot, or whatever, but any Toshiba Utility isn't going to work with a Linux file system. Puppy doesn't like it either for the Puppy sfs saved user file (although it will usually work if I copy them there manually, rather than allow them to save automatically).
3) Extending /Home to the SD Card
I thought I'd just have to copy stuff to the SD Card manually, as extra storage, when /Home got too crowded and cosy. Then I noticed that as soon as I inserted the SD Card it immediately got added to the total space avaialable shown by the Disk Usage Analyser accessory (which just happened to be open at the time). So now I see 10.8GB total, which is plenty to start out with for me. I assume this is because the SD Card had been formatted to mount as /Home when I first tried that solution, and got recognized as soon as it was inserted in the slot.
Questions:
a) Will this work? Will /Home really use the extra space, or is it just "pretending"?
b) Is there anything special I might need to do?
c) What do I do with the three folders already on the SD Card, obviously put there during the failed attempt to install /Home on the card? (The third folder is hidden: ".ecryptfs".)?
d) Is it acceptable to leave swap with just 1.0GB, since I don't need to hibernate?
e) Anything else I need to consider?

I need to browse the net more securely and bypass throttling by an infrastructure-dictator by creating a SSH Tunnel directly to my internet service provider and use it as proxy.
I tried both a dynamic and local tunnel, was a able to connect to the server and log-in just fine, but when I tried to surf I get a 'Connection refused' error.
Here's what I tried:
Code:
ssh -D 8022 user@tunnel.host -N
ssh -L 8022:tunnel.host:8080 user@tunnel.host -N
(not at the same time of course)
Then I set 127.0.0.1:8022 as proxy in browser settings. As long as the tunnel is open the browser displays a blank page with no error when I try to open a remote web page, while the terminal gives me a 'Connection refused' error.
I'm using OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 on Xubuntu Hardy.
In case anybody is wondering this is perfectly legitimate. The tunnel.host I connect to is a server set-up by my ISP specifically for this purpose.
Either of the examples above should work as others who have the same ISP reported that it works. Therefore, I suspect this is an issue with my own security settings which are slightly on the paranoid side but I can't figure out what. Stopping ufw and explicitly opening port 8022 didn't help.

I'm trying to establish a connection between two laptops using sftp but am getting the following error message:
Connecting to <IP>...
ssh: connect to host <IP> port 22: Connection refused
Couldn't read packet: Connection reset by peer
ftp isn't working either. Both machines are running Ubuntu and connect to the internet through the same wifi router in case that's relevant. What could be the problem?

I cant connect with ssh to my workstation using my notebooks wireless lan. with cable I'm able to connect.so the funny thing is, if I first establish a connection from my workstation to my notebook (like ssh it or just ping the notebook) I'm able to create a ssh connection from my laptop to the workstation using wireless lan.scanning my workstation from the wireless lan of my notebook with
Code:
nmap -sT -p 22 ventury
says port 22 is closed
scanning it from the notebook with cable lan,it says port 22 is opened
scanning it from the wireless lan of my notebook an have sent a ping from the workstation before says port 22 is opened.ution.
I got a 64bit version of Kubuntu 10.04, up to date, installed on both, my workstation(ventury) and my notebook (defiant).the question is: Do I always have to ping my notebook first if I want to ssh from it to my workstation or is there some other solution? And why does it work fine with cable, but not with WiFi?

having a port 22:connection refused problem with SSH. None of what I have read has been what I have been experiencing, so I figured I would post here. The worst that could happen is this gets completely ignored, or I am told that there is already a solution, that I missed it, and directed to it. Here is my problem:
Just learned how to ssh into my machine a few days ago. Everything has been running smoothly until I ran into a little problem: all of a sudden I can't connect anymore. I have sshd-server installed and updated. I have sshd turned on
Code:
/sbin/service sshd start
And I even ran:
Code:
/etc/init.d/sshd start
Because I was told that it would start ssh from boot. Nothing has changed from today and yesterday and I haven't been having problems with port 22 being blocked.
I have also tried to ssh into the machine by the machine itself:
Code:
ssh <IP of machine>
with the same error.

I installed Ubuntu Server 10.04 on a dell inspiron, twice just to make sure I didn't mess something up. Apache and SSH work fine post boot. Eventually, just inexplicably, it stops working. SSH is refused and Apache doesn't seem to be running, or it is and it's blocked. What really gets me is that I installed ssh on many many other machines on the same network, even the same ip range and they work fine. They never eventually refuse access for no reason. I checked the startup on the machine and ssh / apache do start at boot... so I'm not crazy there. It does have a static IP but so do many other machines... so I can't believe it's the router / firewall. Especially when I can connect at some point, then it just decides to stop

I have been trying for weeks to solve this one and have researched everywhere I know to look. Nothing has helped. I am trying to ssh to my other machine (machine1=galla, machine2=cachin). Both run Maverick Meerkat 10.10. I get the following error when trying to ssh to galla:ssh: connect to host galla port 22: Connection refused
uname -a outputs:Linux galla 2.6.35-27-generic #48-Ubuntu SMP Tue Feb 22 20:25:46 UTC 2011 x86_64 GNU/LinuxAlso, sshd does not stay running. I can start it, but a ps tells me it is never running. I imagine herein lies the problem. But why won't it stay running?I am not running any firewall on galla (iptables -L told me that).P.S. I can sucessfully ssh out of galla to cachin. And, even if I just try to ssh localhost on galla, same thing happens.

Connecting remotely through FileZilla works ok, but I can't connect from localhost (FWIW I'm running WordPress and would like to be able to upload plugins from the dashboard).
I've got vsFPTPd installed and - I think - running:
Code:
# service vsftpd start
vsftpd start/running, process 25782
All ok so far... however I can't see it on any of my ports:
Code:
# nmap localhost
Not shown: 995 closed ports
PORT STATE SERVICE
22/tcp open ssh
[code]....
And of course if I
Code:
telnet localhost:21
That's 'Connection refused...'
Nothing in 'netstat --listen' either.
The odd thing is, I can connect fine using FileZilla.
To confirm, I have
Code:
local_enable=YES
set in my vsftpd.conf.

I have 4 boxes on a local network: 2 with XP only, 1 with Ubuntu 9.10 only, and 1 with both. All boxes can share folders, set up with share-admin instead of using Nautilus right-click properties for each folder. I can see and control the remote desktops on all boxes, to all other boxes, from all other boxes,with one exception: I can only access the XP desktop on the dual boot box, not the Ubuntu desktop. When I try I get: "Connection to host 192.168.1.102 was closed." I am refused access to the Ubuntu desktop in this manner from both the other Ubuntu machine, and from both XP machines.
My setups are basically plain vanilla with routine installs of Ubuntu 9.10. On the XP machines I am using TightVNC on the XP machines to view both other XP desktops, and the Ubuntu desktop that is accessible. On both Ubuntu setups I am using (I suppose) vino and vinagre, and have completely re-installed what I think is the relevant software. There is no firewall running on the Ubuntu dual boot, when I check ufw. For reasons I cannot determine the inaccessible Ubuntu desktop is not providing its own address but instead in the Remote Desktop config dialogue it identifies itself as 27.0.0.1 which I think is the loopback id. I know so little about this sort of networking that I am not giving all relevant info, but I still thought I'd try.

I forwarded ports 28900(TCP/UDP) and 5029(UDP) to my linux box for a game. Testing my ports with a website now shows these ports as "connection refused" rather than "timeout" which means the connections are getting to my system but the iptables are blocking them. But I added 28900 as a test and it still won't accept anything on this port. This is my output of iptables -L
root@BPC3:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:28900
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:28900
What do I need to do exactly to add exceptions for 28900 TCP/UDP and 5029 UDP?
