Fedora :: KVM Not Working On FC10 - Unable To Complete Install: 'socket Closed Unexpectedly'

Dec 9, 2009

While creating a new VM for Win2K, I guet the following error when I try to "Finish":

Code:

Unable to complete install '<class 'libvirt.libvirtError'> socket closed unexpectedly
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/create.py", line 717, in do_install
dom = guest.start_install(False, meter = meter)

[code]....

This looks like a SELinux issue, since I do get a warning: SELinux is preventing qemu (qemu_t) "search" to / (fusefs_t). I'm attaching the complete SELinux Alert.

Ubuntu :: Svn: Network Connection Closed Unexpectedly

Jul 20, 2011

As the title implies, I'm having an issue with svn, whenever I try to make an svn action, I get: svn: Network connection closed unexpectedly

I've done some Google-fu on this, and the obvious culprits don't seem to be at work. Specifically, the svn server does not use a nonstandard port, and I'm not using Tortoise SVN or putty, just going directly from the command line. Additionally, I was able to use the server as recently as this morning and no coworkers are having problems.

Programming :: How Could Server Detect Closed Client Socket Using TCP And C++

Aug 6, 2010

Reading some examples on net and copying some codes I was able to build a (frankstein) server that accept connection from one client and receive and send messages to it. The big problem that shows up is that I don't know when client disconnects from my server.

I've been looking for a solution, but no success. I'd read about SO_KEEPALIVE option (which could solve my problem), but I don't know how to use it (how to check the value of it).

I can't use ping because the server (machine) could be running, but not the client (software).

Anyone knows a good tutorial or how to (for beginners like me xD) of TcpIp sockets using c/c++ and how to detect when a client disconnect?

I don't know sockets very well.

Ubuntu Servers :: "Error: Server Unexpectedly Closed Network Connection"

Feb 22, 2011

I have a problem between a jail root (so a group of users can access through sftp to Apache directory (var/www) an not get out of this directory.

1. I have the group 'sftponly', I need to access / var / www for sftp (read only)

2. On the other hand I need that user www-data (Apache) is the owner or at least have write permissions in the same directory (/ var / www)

The problem comes when the two needs together, as from what I read, to do jailroot in a directory is necessary for the owner is root and any other user has write permissions on it.

If along the jailroot with write permissions then attempt to connect to the client via sftp throws me the following error: "Error: Server unexpectedly closed network connection"

Permissions system User/group/Others doensn't work to me, so I tried it with ACL, but I have the same problem when I grant write permissions to the apache user.

Does anyone know how can I do for the user www-data can have write permission in the Apache directory and be able to create a user or group of users who are "locked"in this directory to enter sftp?

Ubuntu Security :: Pgadmin3 Through Ssh Tunnel - Error Connecting To The Server: Server Closed The Connection Unexpectedly

Mar 1, 2010

I'm using Postgresql 8.4.2-2. I'm trying to remote into my server securely. I figure I could do so with ssh. Apparently I figured correctly, as per, [URL] and [URL] I setup the ssh tunnel. ssh -L 5432:serverip:5432 Then I setup pgadmin3 to connect as follows:

host: localhost
port: 5432
user: postgres
maintenance db: postgres

And I receive the following error:

An error has occurred: Quote: An error has occurred: Error connecting to the server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.

I'm not sure what the problem is. I can connect with Code: psql from the cli after connecting to the terminal via ssh. So I know that I'm using the correct password.

Debian Configuration :: Cannot Open Java Socket - Port (9955) Closed

Feb 26, 2010

I have a java application that I wrote recently. It runs off port 9955. The application runs great on my mac server. When I installed it on my linux box i cant get to it from outside the box. A port scan shows the port as closed. I flushed my iptables, did not help. I can telnet into the app locally, from the server and it works great. I cannot telnet from outside the server. I have a reference to the application in /etc/services as a tcp port (which it is).

netstat shows it as listening
netstat --listen
tcp6 0 0 [::]: SimpleSocketTest [::]:* LISTEN
netstat -anp | grep 9955
tcp6 0 0 ::: 9955 :::* LISTENá1484/java

Programming :: Poll() System Call Not Returning When The Socket Is Closed Locally?

Sep 29, 2010

we have a multi threaded program on Linux where one thread is waiting on poll() system call with event set to POLLIN, & another thread has closed the same socket fd (which is passed to poll) , but the poll() did not return, is this the expected behavior? From man page of poll we found that the poll should return POLLNVAL if the socket fd is closed, is my understanding correct or is there any bug in the poll()?In Solaris we observed that the poll system call is returning with POLLNVAL if the socket is closed.

Fedora :: Get Broadcom 4312 Working Again Since FC10?

Nov 23, 2009

How do you enable repos? Namely RPMFusion set? I have 2 repo's that are currently in stalled:

[root@dv5-1235 Joe]# yum repolist
Loaded plugins: presto, refresh-packagekit
repo id repo name status
fedora Fedora 12 - x86_64 enabled: 19,122
updates Fedora 12 - x86_64 - Updates enabled: 755
repolist: 19,877

I'm trying to get my Broadcom 4312 working again since FC10. I noticed that RPMFusion isn't listed. This would answer why I can not install Broadcom -wl.

Fedora Installation :: Unable To Login After Fc8 - Fc10 Upgrade

Apr 20, 2009

I upgraded to fedora 10 using yum but i have a problem, the installation went fine and after rebooting i got a login screen. I typed in my user name and password and after a second it returns to the login screen. Im sure the username and password are correct. If i type in another password i get an error message. So how can i log in?

This is what i did to upgrade to Fc10:

Code:

Then i got an upgrade wizzard and selected Fedora 10 and than reboot.

In the grub menu only one kernel is present which is the Fc10 so couldn't use the old one.

I've tried to edit the kernel with single for single user that works gives me a command line but im just not experienced enough to figure out how i can use the command line to login.

Fedora Installation :: Yum Not Working After Upgrade From FC10 To FC11

Jun 22, 2009

I've been running FC10 with all updates and had downloaded the FC11 DVD. Yesterday I upgraded to FC 11 using the DVD and it appeared that everything went fine. However when I tried to do ayum updateI got the following error. There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:

No module named yum

install a package which provides this module, or verify that the module is installed correctly.

It's possible that the above module doesn't match the current version of Python, which is:

2.6 (r26:66714, Mar 17 2009, 11:44:14)
[GCC 4.4.0 20090313 (Red Hat 4.4.0-0.26)]

go to the yum faq at: [URL] I'm not sure what to do next. I also noticed that all my previously configured repositories are lost.

Ubuntu Installation :: Error "Sorry The Program "ubiquity" Closed Unexpectedly"

Jan 27, 2010

I've tried two seperate downloads of the 9.10 installation media with the same results, I can't get to the installer. Each time I've tried it boots into the livecd portion. So how do I install this thing? I've even tried from the System/Administration/"Install Ubuntu 9.10" option on the livecd top menu, but get an error: "Sorry the program "ubiquity" closed unexpectedly" there is nothing that explains the installer not running in either dmesg or /var/log/messages. If the livecd can boot, why does the installer not load. I am selecting the "Install Ubuntu" option not the try it without installing option.

Fedora Installation :: FC10 - Graphics - Unable To See Any Text On The Screen

Apr 20, 2009

Trying to install FC10 on an older Dell GX150 machine, and I get to the point where the graphical install app loads, but I am not able to see any text on the screen, other than the back/next buttons, and when I click on next, I can see that it goes to a new screen where it looks like it's asking for some text input, but I can't decipher what it's asking for, and if I try to type in the box, nothing happens.

I think I read somewhere on here about using a different boot option to get FC10 to work in a Virtual PC, but not sure if it would apply here (and can't seem to find that thread anyway!) I am booting off the FC10 DVD, and can get to the menu to install/upgrade, rescue, boot locally, or test memory. If I hit TAB, I can edit the boot option - I just need to know what to put in there to get this to work!

Fedora Networking :: Eth0 Suddenly Stopped Working On FC10

Aug 4, 2009

my eth0 suddenly stopped working on FC10. i have been using it the whole time, and now it refuses to even ping the gateway. dhclient is not receiving a dhcp offer and when i put in the information manually, it is not even able to ping the gateway. netstat -rn shows that the destination of the router is going nowhere.

i do not think it is the hardware/software, but rather maybe the provider? i am from central europe but just moved up to great britain and working at a friends place. i can connect the mac powerbook without a problem (it will get an ip with dhcp), but not the linux machine.it is a normal ethernet modem connection here. can it be, that it checks MAC addresses or even the computer names? the powerbook also has a really weired IP address: 77.102.xxxxx

i am not using network manager, but command line tools and have nm uninstalled. does anyone have a clue, what this could be about? i am not a newbie, but this is really puzzling me.....

Ubuntu Installation :: Unable To Complete 10.04 Install

Decided to upgrade my 8.04 server to 10.04 today. Everything went smooth when I tried to install in vmware. When I tried to install it on my real machine the installation hangs at 74% Storing Language...

I've checked the disk and I tried different ways to install (different language, both keyboard and system). The first two attempts the installer just turns off and the computer reboots. This third time it just hangs. how to debug and solve this problem?

It's the x86_64 version. I'm using the standard options all the time including LVM on whole disk.

Fedora Networking :: FC10 - Unusual System-config - Unable To Ping Other Computers Or Routers

Jun 2, 2009

I recently built my second general-purpose server, and recently installed fedora core 10 on it. The first thing I attempted to set up after installation was the network - and that's where it's gone wrong When editing a network device using the graphical system-config-network utility, I find that the subnet mask is being automatically changed to match the default gateway address every time I attempt to modify any of its settings (or sometimes even when I cancel the changes). This also means that I cannot set the subnet mask, as it simply won't accept my setting for it. I seem to be able to get around this glitch by setting the subnet mask using the shell version of the same utility, but that doesn't solve my network issue.

Even when I use the shell utility to fix the subnet mask, I'm unable to ping other computers or routers on the network even when ifconfig indicates that the desired ip address has been taken, and other computers on the network are also unable to see the server. I'm using a wired connection and a static IP address on a network with no DHCP.

Fedora Installation :: Moving FC10 From SATA To PATA - Unable To Access Resume Device

Jan 26, 2010

I'm trying to move an existing FC10 install (created by someone else) from a 160GB WD1600AAJS SATA disk to a 160GB WD1600AAJB PATA disk (cursed trend of horizontally mounting SATA connectors at the end of the motherboard means the latest rev mobo doesn't fit in our enclosure!). I've used DD to copy the disk image from one to the other, but when attempting to boot, I get the following error:

Code:

Unable to access resume device (UUID=946f216f-0c24-4b02-a996-f42059970de7)
mount: error mounting /dev/root on /sysroot as ext3: no such file or directory

That particular UUID maps to sda2, which is the swap partition. Interestingly, both the SATA and PATA disk come up as /dev/sda on the motherboard. I kind of grok that the UUIDs are substitutes for directly naming the disks, and that they're referred to in fstab, initrd-2.6.27.12-170.2.5.fc10.i686.img, and in /dev/disk/by-* I'm guessing the problem is that the GUIDs (at least the one for swap) are no longer the same. How are they assigned to the partitions during boot?

I tried doing

Code:

swapoff -a
mkswap /dev/sda2
swapon -a

and put that new GUID in fstab and into initrd-* (using some steps I found elsewhere on how to gunzip/rezip it).At that point, I get a kernel panic on boot

Code:

Kernel panic - not syncing: CFS: Unable to mount root fs on unknown-block(0,0)

So I'm guessing that the other UUUDs have changed as well and I need to update them. How would I figure out what they are? I suppose I could change the references to /dev/sda*, but I didn't build this original image and I'm thinking whoever did had a good reason to go with UUIDs.
