Fedora Security :: Why Gvfsd-computer Accessing The Internet Without Requesting Such An Action?
Aug 9, 2009
Today I noticed my sdl modem flashing away when I had no internet access programs active as far as I was aware. I did a 'ps ax' to see what was running. I saw nothing that warranted internet access. I didn't recognize the gvfsd-computer process and tried finding documentation about it on my system. I began to feel uncomfortable when I couldn't find anything showing what it was. Finally, I killed the process and the internet access immediately stopped. Research on the net showed that gvfsd-computer is a file browser. I find this very disturbing. Why was a file browser accessing my disk drive (the light was flashing) and why was it accessing the internet without my requesting such an action?

I'm trying to do the normal setup of sharing some dir's on my linux machine using samba, to allow a windows laptop to access them.
I've managed to get the printer shared and this is allowing to send print jobs, which come out beautifully! however the actual file shares still aren't accessible
Depending on my settings, if I have security = user then when I access from the windows machine I get a username and password box - I dont want this functionality, I want the system to access right away as it would between two windows shares.
If i change security = share then it simply lists the shares, but tells me they are all inaccessible.
I've googled and searched here, tried various different things but I just can't see why/where its asking me for the username/password combo.
Code:
From /var/log/samba/smbd :

I've been trying to figure out how to access tomcat6 pages outside of the computer actually running the tomcat6 server. I can access the tomcat6 web pages fine on the computer running the server, but I can't seem get to it on another. I'm probably not setting it up correctly or something, but I've attempted to access the tomcat6 server by following this form:

Did I not set up the tomcat6 server correctly?

I installed Gnome Nanny. I can choose the times when the computer can be used and limit the internet. However, these times are not being enforced. Is there some other settings that are used to enforce these settings?

We installed Fedora on top by my WindowsXP, we have updated the connection information with the addresses, but can't access any website. Connection Manager says we're connected. We created a new wired network connection, but it doesn't appear in the choices.
I installed Ubuntu recently and had a similar problem, only mine was that my computer was competing with hers (something to do with DHCP). The solution was to alter my /etc/network/interfaces file, but I also screwed with settings in the "Network Connections" thing, pretty much altering a connection my /etc/network/interfaces file seemed to have made. My problem was only solved as far as I cared. I wonder if this is the same problem.
On the other hand, we attempted connecting the Fedora box directly to a modem and still no internet, so I believe they are entirely unrelated. But I wanted to include this for completeness in case they are.

I have seemed to work out all bugs in pulseaudio except 1. When pulseaudio wakes up it stutters for a few seconds and then plays fine. I ran pulseaudio -vvv in the terminal and found that it was an underrun and got this message.
Code:
protocol-native.c: Requesting rewind due to end of underrun.

I use a commercial finite element code to produce animated GIF files of my calculation results. In case you are interested, the code is COMSOL Multiphysics 4.0a, running on Fedora 13 x86_64. Note that the FEA code only has the option of saving movies as animated GIF files in Linux.
These GIF files tend to be quite large, and although they are adequate for my own use on my local computer system, I wish to convert these files into other standard formats of more manageable size. These smaller files would then be easier to distribute to others or to include in presentations and reports.
I would like to ask for recommendations for either GUI-based video player/conversion applications or command line codes that could, for example, convert from animated GIF files to MPEG files. I would prefer an application that allows for multiple input/output format choices as well as conversion options for changing the playback speed, splicing out a portion of the original animation, etc.

I am using SSH forwarding for accessing particular ports of a distant computer no problem. I also want to access another computer`s ports as if they are local without individually forwarding ports. In a way this distant computer will become a local computer over the internet. So instead of having localforwarding in my SSH config I just want to be able to say that this IP adress will accept all the port connections, butall those connections will be forwarded to a distant computer over the internet.

I would like to have a server set up at home and be able to access it using a front end that I would boot from a USB drive. The reason I would do this is because at my university all of the computers are horribly slow, I have a server at home that is fast, I would sit down at one of the computers use a USB drive to boot up the computer and use it as a front end, the computer at home would be the backend. Is this doable? if so how?

[URL] This web page says: "The team set up weak security on four Linux computers with Internet access, then recorded what happened as the individual machines were attacked. They discovered the vast majority of attacks came from relatively unsophisticated hackers using "dictionary scripts," a type of software that runs through lists of common usernames and passwords attempting to break into a computer."
How did they "record what happened as the individual machines were attacked"? How did they figure out that "the vast majority of attacks came from relatively unsophisticated hackers using 'dictionary scripts'"? What I am really getting at is that I've searched the net and found lots of advice on how to detect if your computer has been hacked but I haven't found ways to know if your computer is being attacked. Obviously, this group did that.

I recently set up a network of computers via Ethernet, all of which use Fedora 10. I would like to be able to get any computer on the network to hook up to the internet.(I think the solution is now figured out - see below, on page 2, "problem solved")

1. Text of the computer and Internet is very small. I merely see it. How may I increase it? I have Fedora 12 in my computer.
2. Evolutin don't work. It don't send letters and don't receive them.

Just finished a security update, (Fedora 12) and it said I had to restart the computer to have it take effect. When I restarted, all I got was the "Compaq" logo....forever. No Grub2 (it's a three system set up), no bios, just the brand name of the box. Even worse, when I tried going at it with a live cd, the same thing; the bios never loads, so no live cd fix.

I have so many _wired_ devices that I can't get by with just 4 eth cable outlets anymore, so I thought I'd hook up an older router that I don't use as a way to get extra places to plug devices into.
Now it looks like:
Internet
then cable modem
then router1/wifi + (1 eth NAT storage)
then router2 + 4 eth0 computers:
(legacy FC5 box)
(legacy F11 box)
(updated F13 box)
(windoze)
All of the computers EXCEPT the FC5 box are fine (my def of "fine" is I can ssh to and from the other computers and to outside computers, and browse the web).
The FC5 box, however, can ssh to and from computers inside the network just fine, but can't get any kind of web browsing. Nor can it ping to the outside. I get a "Network is unreachable" error. I'm not using a proxy, not knowingly, and my firewall settings haven't changed...it certainly hasn't been blocking port 80 before.
what's the best way to go about adding more ethernet when you need about 7 cables. I'm not really excited to buy a router with 8 ports or anything like that, especially when this seems to _almost_ be working just fine.

I've just added my wife as a seperate user on my desktop and have a question about shared network folders. So /etc/fstab mounts network folders from a second computer and until today I've mounted them to /home/David/NetworkData
This of course means that when my wife logs in she won't see them since they're not mounted to her home folder. So what folder should I use and what tricks so that we both have it visible and accessible in Places from the top menu?

I just got my Ubuntu 10.10 laptop to finally be able to access my Windows 7 Professional's shares, and I'd like to share how I got it working. Whenever I would go to Places > Network on Ubuntu, and then double click on my Windows computer (sometimes after finding it in Windows Network > {workgroup name}), it would immediately bring up a box saying "Password required for {computer name}". My Windows password wouldn't work here, but I didn't even want to be asked for a password. In Windows, under Network and Sharing Center > Choose homegroup and sharing options > Change advanced sharing settings..., Turn off password protected sharing was already selected.
So, I eventually found out that samba (the program Linux uses to talk with Microsoft's SMB network share protocol) has a bug of sorts. The format of the SMB packets coming from a clean Windows 7 is known by samba. However, if you install Windows Live Sign-In Assistant (which is provided through Microsoft Update) on Windows 7, the packets coming from Windows 7 are modified, and samba can not handle this. A patch has been written for samba, but Ubuntu's repositories (which has samba version 2:3.5.4~dfsg-1ubuntu8.1) does not yet have that patch.
Also, it seems Microsoft has stopped Windows Live Sign-In Assistant from appearing in Programs and Features. It doesn't appear even if you specifically download and install it separately. I did, however, notice that the installer calls itself Windows Live Essentials 2011. So I found that in Programs and Features, and uninstalled it. It asked which components I wanted to uninstall, and I selected all of them. Rebooted Windows, and now I can access the share no problem. I also grabbed the offending packet using Wireshark before and after that uninstall. The packet is indeed different. Specifically, without Windows Live Essentials 2011, there is no mechToken in the packet.
The current version of samba available is 3.5.6. I may try downloading and compiling that later, and see if it deals with the change that Windows Live Essentials 2011 makes OK. Also, it may be possible to get the share working without uninstalling every single Windows Live Essentials 2011 component. You may want to try that if you would like to keep a component.

Looking at the results of both `lsof | grep IPv4` and `netstat -tp` I noticed that I have a lot of connections open from a program called 'gvfsd-http'.
Using google, I found that this was a Filesystem something from Gnome, that would also be used If I drag something from my browser to my desktop.
Though I wonder, how I activated it, because I didn't do that...
After a bit of searching, I noticed that `screenshots.debian.net` uses the same IP address as the one noted (hades.car.gr).
PING screenshots.debian.net (78.46.20.5) 56(84) bytes of data.
64 bytes from hades.car.gr (78.46.20.5): icmp_req=1 ttl=56 time=55.4 ms
Question: Do I have some tool enabled that maybe sends statistics to debian or so? Where to find it and kill it.

I have set up a FTP server in my home (FileZilla) and everything works how it is supposed to. I understand that port forwarding is required and can easily set that up. My question is what IP address do I use to connect to it when I am outside of my home network. Do I use the one my ISP gave me? And how do I figure out what that is? Could my ISP be using NAT that could be messing things up for me? Could there any other configurations that I need to perform ? Also do ISP's frown upon home ftp servers? (USA)

- I have setup an application in my local subnet 10.1.0.0/16 which broadcast udp packet.
- My application broadcast from machine with 10.1.2.240 and also broadcast from multicast address 225.1.2.3 using port 3035 (it's the correct multicast address right ?)
- I have develop small application to receive the udp packet from the multicast address. It's running OK.
Problems/question :
How can i setup my firewall (using shorewall) so that user from internet can receive the udp packet from multicast ?
Is it possible to listen udp broadcast address behind the firewall (without setting up vpn connection) ?

I had remote desk running on a machine and I went downstairs the other day, turned it on, and someone was controlling the machine. Of course that's partially my fault since there was -zero- rd password set. However, my question is how did this person figure out my IP and get past the router to the machine? I don't have any forwarding setup. My router admin password is (has always been) strong. I guess my question now is: Is there anyway to restrict rd access to the local network?

I want to restrict a user accessing my ftp site.
1) i can block the user in ftp configuration file
2) i can block the user in PAM or /etc/host.deny
i heard that if pam is denying the user and ftp is allowing the user the user can get the access it means that ftp conf file is stronger than host.deny

Occasionally my machine displays the following warning whenever left to itself for an hour or so. "www.windowsvistatestdrive.com:443 uses an invalid security certificate. The certificate expired on 09/16/2009 10:52 AM. (Error code: sec_error_expired_certificate)"
I am not trying to access this site. It is not always the same url. My machine, described below, is networked to an XP machine which recently had to be recovered after a viral attack. Since I am not usually interested I decline to use the certificate and the warning goes away.

After trying Truecrypt, LUKS, and Ecryptfs I decided to try NTFS encryption. Now, on a dual boot computer from Ubuntu I can browse the encrypted folders but can not open the encrypted files. All attempts produce access denials yet the Unix file permissions appear to be "0777" (owner, group, and world readable-writable).
Is there someway to get Ubuntu's NTFS software to recognize and decrypt the encrypted files? Would a different NTFS package work such as NTFS-3g?

I have a drive that originally was used with a Linksys Network Storage Link (NSLU2), then stopped working with it. Now I'm trying to get the files off the drive. When I USB connect the drive to Ubuntu, I can see the files, but I'm unable to open them or copy them. The error message is: "Error Opening File: Permission Denied". I did have permissions set on the NSLU2. So far I'm not able to find a way to get around the permissions issue in Ubuntu.
I have used apps like EASEUS Data Recovery and Recover My Files. It appears that they are finding the files and are able to access them, so I know it can be done. I don't mind spending some $, but these apps are taking a *long* time to run. If I could properly access the files in Ubuntu long enough to copy the files, I think I'd be all set.
