I successfully set-up an FTP server, that worked great and perfectly, but after restarting the computer, it has stopped working.None of my router's settings have changed. I restarted the vsftpd process.
View 2 RepliesFor more than a year I was happily using my Fedora 11 remotely through VNC over ssh. I was using desktop 0 on port 5900 so people at the office can see what I am doing.
Yesterday I upgraded to Fedora 12, then 13 and then 14. I installed all updates of F14. All went well until I came to use this server from home as usual. The server was not responding.
I brought up /etc/X11/xorg.conf from a backup tape because I discovered that it is there that screen 0 is set and not in /etc/sysconfig/vncservers and rebooted. No success!
At the command lsof | grep LISTEN, I could not see a listener on port 5900
I activated screen 1 on port 5901 and I could log in OK and with lsof I could see listeners for ports 5901 and 6001 but I need screen 0!
During the day I tried many things including removing the vncserver packages with yum and re-installing them, removing the .vnc folder in the user home folder and starting from scratch. The server is still refusing connection!
Well I guess the topic says it all. I've recently upgraded to Maverick from Lucid all went smoothly until i restarted and realized that the remote desktop server included stopped functioning all of a sudden. tried other vnc servers with no luck.
View 9 Replies View RelatedI am using Ubuntu 10.04. In the summer a few months back, I managed to get my ancient HP Laserjet 6L printer working via a wired D-Link-DPR 1061 print server and Netgear network switch. This was even though it was not on the print server's compatibility list. A couple of months later it stopped printing and I have not been able to get it going again since.
The print server has one parallel port (used by the 6L) and a couple of USB ports which I don't use.
I have been going through the Ubuntu add printer wizard. The print server can connect via an IP address. I am using its device URI: lpd://ip address/dlk-portname
I have tried all 5 HP laserjet 6L drivers that come with Ubuntu without success. I have the foomatic/ljet4 [en] currently selected. When I try to print a test page nothing is printed and when I do a print self test I get this message:
CUPS SERVER ERROR There was an error during the CUPS operation: 'client-error-document-format-not-supported'.
By, the way I also have a Windows 7 PC and managed to get the 6L working with same print server using the XP drivers, but every so often it stops working. A reinstall gets it going again.
After using fedora 11 for a month or two now the ethernet gave out on me tonight. However if I switch to my ubuntu or windows XP install it runs fine. I made no recent changes to network connections, and no installed programs that should effect it.

I have tried, restarting, older kernel, restarting services, and clearing the DNS Cache. The specific error I get is that "Firefox can't find the server", and most other applications return similar. I can however ping websites still. All other computers on the network are running fine, and booting into another system the internet will work. Just not for fedora.
When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
There are a few threads about this but none seem to me.I have 3 machines setup with a nfs home directory on machine 1.I have created keys using ssh-keygen -t rsa (and left everything blank), then as user on machine 1 run
Code:
cat id_rsa.pub >> authorized_keys2
chmod 644 ~/.ssh/*
this used to work until I upgraded to ubuntu 11.04 (from 9.04), and now it requires a password to ssh. I have tried several times deleting ~/.ssh/* and recreating, to no luck Below is the results when I try to ssh into -2 from -1:

(dumb question, but shouldn't the offered RSA public key be id_rsa.pub rather than id_rsa?)
Wired and wireless networking have been working flawlessly for years on my HP Compaq 6710b laptop. Several weeks ago, after an automatic update via the update manager, my wired network stopped working. I did not notice it directly, since my wireless connection took it over. I only noticed it when I had to work in an office where I didn't know the wireless password.Since then, I have been trying several things and searched several forums. It is hard to find any troubleshooting information about wired networking, as most of the problems seem to occur with wireless.
I did verify that there is no hardware problem. My laptop is dual boot and when I boot the other operating system, the wired network works without problems (as does the wireless.)My Ubuntu version is Ubuntu 10.04.1 LTS. My kernel version is 2.6.32-25-generic i686. I hope anybody can help me getting my wired network working again.
My server was set to automatically install updates, and stopped working while I was away. When I got back to it, it now has a boot menu to choose between kernel versions, with no default or timer. So I pick one, and there are heaps of other problems. the /home partition isn't mounting, despite the fstab being unchanged. I can mount it manually using mount with no problems /var/syslog has nothing since April, and isn't updating when I reboot, so I'm not sure what I can cut and paste to here for you all to look at. The networking isn't running, in fact, most of the network interfaces aren't even showing up.That's just what I've identified so far. I have no idea where to start. I can't find anything wrong other than the fact it's not working.I can't copy and paste any output at this point, because I can't ssh,

Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.
I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?

I have had ubuntu about a month now and everything has worked great up until now, I was surfing the web and all the sudden I lost connection. I tried to connect to the signal but got nothing so I did a reboot. After the reboot my wireless signal didn't show up. i right clicked the connection icon on the top taskbar and the enable wireless is blacked out to where i cant click it.

View 1 Replies View RelatedI have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.
Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.

Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).
When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB. Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.What could have occurred, and how might I troubleshoot it?
Just recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.
However, this time nothing is working. I've provided some detail and if more information is needed, let me know.

View 6 Replies View RelatedBeen searching for hours and looked at several other threads but still can't figure this out. We have 4 folders being shared from a Ubuntu 10.4.2 LTS Server using Samba. A couple days ago two computers in the office lost access to these shares. The other computers in the office are fine. So far as I know nothing has changed on the server. I can putty into the server still but I can't map a drive or open a window through run (\server_nameetc).
I've also tried disabled iptables on the server and windows firewall on the the windows xp machines. Still no luck. What am I doing wrong? Like I said, so far as I know there have been no changes to the server whatsoever. One day it was working and the next it just stops.
I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.
View 1 Replies View RelatedI'm in somewhat of a sticky situation. ssh has just randomly stopped working on my server after a power failure. Everything else that doesn't rely on ssh is still working fine though. It can still receive mail and everything, just no ssh.Background on the server, running debian etch on a PPC machine.ssh is (supposed to be) running on port 2000. Even if I am physically logged into the machine I can't log in with ssh -p 2000 user@127.0.0.1.
I can ssh to and from any other machine on my network (the server can even ssh into another machine). So it isn't my network causing issues.It seems like the port 2000 is completely closed, if nmap the server's IP address I get PORT STATE SERVICE

i have just setup a firewall using iptables on centos 5.3 but there's an issue with ftp
i can connect and i can login when i give command "ls" it says entering passive mode
and afterwards it times out do you know why? i have port 21 open in my firewall but still....
sometime ago i have setup a nice Debian FTP server. and left the company. everything was working fine for about 5 month, administrator was able to login to root, do changes and manage system, etc. Suddenly he told me that he cannot login via PUTTY, the root user and pass say Access Denied.Looked all over the web for at least a REASON, but did not find anything. I suggested to go and do passwd reset, via runLevel 1. i hope this helps him. But i am still curious why all of the sudden, in a locked down room, where only one person has access root get disabled.

I switched my FC11 system off yesterday. Turning it on this morning, NO domain names can be resolved anymore.I can ping IP adresses directly, and even get to them in FireFox if I type the IP address. However, typing any domain name at all fails. I cannot ping or SSH to any domain name, but as soon as I enter an IP, it works. I can ping the DNS server by IP that is set in my /etc/resolv.confI checked on an XP system using the same DNS server set in /etc/resolv.conf (which can also be pinged on IP from my FC11 system), on the same connection from the same ISP, and it works.E. g. without touching anything at all (and all updates are turned off) my FC11 system has stopped resolving domain names.I'm running 32bit FC11. The system has been working fine for more than 2 years.So it has spontaneously stopped doing DNS when I enter a domain name. Where can I start looking?

Bit of an odd one this. My ZTE MF100 (on O2) had been working happily on my 10.04 laptop, but today is not recognised - e.g. no device listed by lsusb, nor error messages in dmesg at boot.
Re-plugging the device after boot gives me dmesg errors:

I've been running ubuntu on my Asus 1001ha netbook for half a year or so. I ran Karmic for at while, wifi working and all, accepted the recommended updates when Update Manager popped up and everything was fine until one day I let Update Manager do it's thing and my wifi stopped working.. Lycid had just come out that same week, so I thought "screw it" and installed 10.04 instead..
So I've been running 10.04 for a couple of months now, everything working fine, including the wifi - until today.. Update Manager suggested some upgrades, I accepted and *pouf* my wifi is gone again..
That's the second time Update Manager knocks out my wifi, any way to roll back todays update or how to the the wifi working again?
I'm using Ubuntu 10.04. I was happily connected to internet and surfing some forum, when wireless connection suddenly stopped working.
Now I can't find any access point, and I'm pretty sure I didn't do anything to justify this behaviour.
It already happened a month ago, but I had to format my drive, so I didn't really bother to try to solve the problem.
Anyway. I'm posting here the results of the commands I think I can help with a diagnosis; if something else is needed.
I'm using a different computer to post this thread, so I'm manually writing the output.

Version: Ubuntu 10.04 Relavant hardware: P5QL Pro built-in ethernet, cable modem with linksys wireless-G router (although problem is with ethernet connection, not wireless)
One minute my ethernet was working, and the next it stopped working. The only thing that I did between it working and not working was install electricsheep from Synaptic and then I shut down the computer. When I restarted a bit later, no ethernet connection shows up.
I checked the cables, made sure they are in tight.
My laptop connects using the same ethernet cable fine. So its not the cable or the router.
I reset the router and the computer at the same time. Still doesn't work.
I don't know where to even start with troubleshooting this sort of problem. Everything to the extent of my computer knowledge seems to be working fine.
