Selective connection problem

Hi, guys.
I have a very punctual problem, let's see if anybody can help:

I have troubles connecting from some specific applications in my machines at home. The issue is both from SolydK 64 and SolydX 32 with my internet server (they don't dialog well).

Details:
1) I can't post at this forum or even send private messages here... (I have to do it from a live session of another distro or system to do so); I do log-in and open boxes to write new / edit old messages, but when I click on "send", it takes some time and I get "time-out";

2) In my BOINC manager, the results from some projects don't get out of my machine (gives me permanently deferred communication, but not all the applications: SETI_at_home goes, World Community Grid and Roseta_at_home don't);

3) I cannot log into Yahoo mail (can do with Gmail, though) (gives an error, almost like the password is wrong... when it's not);

4) My university web-mail gives me the same problem that this forum: I can log-in, open the topics, click on "reply" or "edit", but cannot SEND anything.

Edit: 5) I can't watch Youtube videos any more (this is new... is it related to the problem explained here??)

OBS.: I can connect here from other machines with windblow$, and other GNU/Linux distros in the same computers (live sessions; I don't have / don't want multi boot), but not from SolydXK; and I can send BOINC results form my several SolydXK machines at the university, and log in anything, and send mails and posts, there. This issue happens here in Firefox and in Chromium, so the problem is not the browser, either.

See? The problem is here!

So: where should we look to see if there is a record of these errors in the connection? Is there some "system log" I can send you or post here to analyze and help me to circumvent or eliminate this problem? Do you have any clues?

THANK YOU!
Gonzalo

I'm no expert at this, but it sounds to me like there's something blocking certain HTTP requests from getting past some wicket in your communication path. I think the clue to the common denominator is in your second sentence :
The issue is both from SolydK 64 and SolydX 32 with my internet server (they don't dialog well).
I would think you will get more help if you can better characterize this behavior, provide some details about your computer, and provide some details about your "internet server" - whatever that might be.

That's exactly what I think and have said, Scott.

I have send all the info I could imagine (when and how it happens, when doesn't). I'm at the point where I need someone wiser than me to say "post here this and that file" that may contain request from the machine and the denial dialog from the server... some network log or something like that ;)
Or someone even wiser that can say what this forum, yahoo-mail and youtube have in common that can be inaccessible when I connect from Solyd. When my system send some request, that request is denied or blocked.

The only thing my explanation lacks is: "does this happen with another Debian-like with the same kernel?" I should try some live-CD from other distros to see... but this could be endless.
I can connect with PCLinuxOS (live and persistent), SolusOS, *buntu (my previous distros in usage), etc.

If I don't solve this, I would have to change my home desktop's K64 system (not the netbook X32, for now).
I REALLY hope not.

it appears you have the same network chip I do. Do you have any firewalls installed?on your router or on your computer?

Right. As I have said, it is not a pure hardware problem, since with other distros I do connect.

Now a test: this is SK64 live usb session. If you see this message is cause I was able to post and the problem is the persistent version and/or the kernel... The present one is Linux solydxk 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2 x86_64 GNU/Linux/ the persistent was updated recently? Is 3.9-1-amd64 #1 SMP Debian 3.9.8-1 x86_64 GNU/Linux Although the forum issues is not so recent.

Haaaaaaaaaaaaaaa :shock: it worked. So there is a chance something in the new kernel screwed my connection.


OK, SolydXK wise guys, any clue?? :ugeek:

I suggest we stay always with the stable kernel...

Connection problem (partial) under kernel 3.9.1

Posted: 10 Sep 2013 16:45
by Gonzalo_VC
As I have posted elsewhere in this forum [http://forums.solydxk.com/viewtopic.php?f=8&t=1337], kernel 3.9-1, both 32 and 64 bits prevent some applications to connect to the internet at home (Yahoo mail and groups, Youtube, BOINC manager, and also this very forum!).
Of course it's something related to the internet server I have at home, too, and perhaps the fact that I have a small router in the middle, but that problem didn't happen with the more than one previous kernels I had in SolydXK.

Awaiting for a solution; and a clue where to look to detail the problem, too.

Is the kernel in our distro going to change any time soon? For now I'm rebooting and using the old 3.2.4 when I need to perform some of the tasks the new one prevents. If the present kernel is not a "stable" one, I would recommend to change only from stable to stable, in the distro. I see no use in changing the kernel many times a year, since the previous are working fine... What newer things do we gain that really make a difference? But I'm just a layman in this subject.

Besides that, all is great with my 10 different SolydXK machines ;)

Yesterday (since I didn't get the warning!!) I've upgraded my machine at home. Newer kernel, still not connecting as with 3.2.

The only thing I saw improving is the shutdown screen that appeared again (I got a black screen, before that).

So!!??

I can' t help you further i'm afraid. But about the kernel's change, as for every paquage, SolydXK depends on Debian testing. So most of the update (except SolydXK specific packages or community packages...or community choices as KDE 4.11 for september's UP) are linked to the Debian testing's evolution.
Perhaps for you it is better to keep your system on the 3.2 kernel and test at every update if the new one is useful for you ;)

Yes, I know, mon ami (how "we" depend on the great Debian). Even more: there was an update yesterday (that we are warned not to apply since there is an error, somewhere) and the kernel was upgraded... but my problems there persisted :(
So, I'm thinking that if I don't find an elegant solution, either I would have to remove manually the kernels (shaking legs!) or install another distro I like too.

Could you do a dist-upgrade again?
Both production and testing are equal. So, it doesn't matter which one you're using:

Code: Select all

sudo apt-get dist-upgrade
Also check /var/log/syslog for any errors.

Shall do that (again, right?).
Even applying the update yesterday or the day before, the icon of the update-manager shows new things are there (blue "i").

PS: Well, did that in the terminal. Only the update manager was updated to 1.4.3.
Here are some extracts of my log files, Schoelje (see 2 attached files).

After doing that, nothing else did update or upgrade, as you can see in those files.
Here am I posting after rebooting and using this kernel: Linux gonzalo-home 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2 x86_64 GNU/Linux
The two following ones give me this weird connection trouble.

Thanks for the attention. I think I am not just a "pain... user" ;) since I try to contribute and am using this nice distro in 10 different machines :mrgreen:

hi Gonzalo_VC

I think the kernel is probably not the problem. when you test with a live (coincidence with 3.2), you have not a specific configuration. I see in your syslog (your posts in Bug Control), curious things:
Sep 14 12:24:23 gonzalo-home NetworkManager[2819]: <info> prefix 24 (255.255.255.0)
Sep 14 12:24:23 gonzalo-home NetworkManager[2819]: <info> gateway 192.168.1.1
Sep 14 12:24:23 gonzalo-home NetworkManager[2819]: <info> nameserver '192.168.254.254'
Sep 14 12:24:23 gonzalo-home NetworkManager[2819]: <info> nameserver '192.168.1.1'

you have 2 different address classes of Ip network.
I imagine that concerns you Dhcp server? have you a different dhcp server that your gateway? have you install a dhcp on your Pc?
what returns:

Code: Select all

dpkg -l | grep dhcp
but this is only a single track, it may be there another reason

OK, zerozero, here I am :-)

kyodev, I have 2 IP because one is the physical one, and the other the logic, given by a small router I have to divide the internet signal for more than one machine, wired and wireless ones, OK? And this has been like this since the begining, and the connection problems appeared later (I have found out about the kernel after many experiments with other Linuxes and kernels). Every connection, live or persistent, will have the same IP structure.

By the way, as I have said above (somewhere) in both machines the present SolydX 32 bits netbook and the desktop PC SolydK 64, I got the same problem and with the older kernel I do connect (no live session, this is a persistent installation, just that I choose the older kernel of the 3... well, in SolydX I still have only 2 (3.4.2 an 3.9.1, no updates, yet).

So... sadness continues :-( I'm going to call Linus to see if he has a clue :lol:

ok, so why not downgrade the kernel to 3.2 with wheezy repo?
you will see if it's better. if you want to know how, ask.

I would like to know 3 things:
1) The rest of the system will be OK if I downgrade, right? It would be just the kernel.
2) How do I do that?
3) How can I modify grub 2 configuration? Because I can just make 3.2.0-4 my default, without uninstalling anything, and can also put memtest in the list (it is not there in my SK, but it is in SX.
By the way, I made a full memtest86 test today and RAM is alright.

Cheers.

PS: I already asked for a script to remove older kernels easy. Otherwise, being a semi-rolling release distribution, we'll end up with 2 pages of booting menu in sometime :-P
