Ubuntu Servers :: PTY Allocation Request Failed On Channel 0?

Jul 25, 2011

I recently ran into the following problem when trying to ssh into my Ubuntu 11.04 server:

>> ssh user@site.com
PTY allocation request failed on channel 0

I don't know for sure, but I think this happened after one of the latest Ubuntu updates I installed. In case it's of relevance, I'm remoting in from Terminal (Mac OS X 10.7 - Lion). Edit: The problem seems to be with Lion..

Debian Configuration :: Network - Access Servers Request Failed

Feb 1, 2010

I recently installed two PC with debian lenny (kernel 2.6.26). One is called serveur-debian1 and the second one serveur-debian2. I have installed gnome,samba, mysql5, apache2, php5, and Virtualbox,bridge-tools on them. On serveur-debian2, i installed an other virtual debian lenny with apache2,mysql5,php5,nagios and centreon on it to view my network. I remember having installed a soft to access nntp on serveur-debian2 in order to test nagios.

Since a few days, i have problem to access to my servers. rom my windows 7 client, i try to ping serveur-debian1. Response is OK but not for all resquets Always from the same computer, i try to ping serveur-debian2. Response is OK but not for all again.

When i launch a ping on serveur-debian1 and serveur debian2 at the same time i have:

ping 1 to 10: serveur-debian1: response OK
serveur-debian2: no response
ping 11to 14: serveur-debian1: no response
serveur-debian2: response OK
ping 15 to 25: serveur-debian1: respone OK
serveur-debian2: @ip serveur-debian1 network unreachable (there's no error, it shows me the ip of serveur-debian1)

If i switch on the debian virtual server on the serveur-debian2, and i ping it at the same time, the response is OK for all resquests. The problem is very strange. I can't have a correct connection and when i launch a request from a software which access the mysql server, the requests failed ...

Networking :: Ssh -D - Channel 6 - Open Failed - Administratively Prohibited - Open Failed

May 24, 2009

I'm getting these messages Over SSH with the -D switch

Code:

At uni I did this for a couple of reasons, primarily to connect to trackers for bittorrent. I would get these messages fairly often but I never thought much of it because I figured I was just loosing packets over the network or something (understandable in my situation). At home I decided to continue to use this method because that computer is set up in DMZ and is very useful. I havn't received many of these messages but recently all my torrents stalled and I had a whole bunch of these messages. Is it possible my computer just cant handle all the network connections (it's a 2ghz AMD running debian)? What exactly do these messages mean? Is there any way to optimize my connection in any way?

Fedora Servers :: Virtual Machine Manager Won't Allow Memory Allocation Over 1024

Jan 26, 2010

I'm running Fedora 11 (2.6.30.10-105.2.4.fc11.i686.PAE) 8 GB memory on a AMD Phenom(tm) II X4 965 Processor, 4 core server I just built.The problem I have run into is any virtual machine that has >1024 MB memory assigned to it will not boot. As along as it has 1024 MB or less it boots fine.The symptom you see is a very quick message "Booting from hard disk" the screen then goes blank, you can't login through SSH, and can't ping the network address so I know it's not some crazy video problem hiding the boot process.The attachment are messages from a failed boot attempt.

Ubuntu :: Adding New Screen Resolution - Request Failed

May 19, 2011

Basically I want to change the resolution on my computer as the desktop is partially lost off of the screen. The needed resolution is not available so I am attempting to add a new resolution. I have used the [URL] for information on how to do this. I am completely new to Ubuntu and entering code so a TON of the results online have meant jibberish to me as people leave out the basics which I cannot find. Here is what I've done so far in the terminal...

I enter:
xrandr
I get:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
HDMI-0 disconnected (normal left inverted right x axis y axis)
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 698mm x 392mm
1920x1080 60.0*+
1920x1080i 30.0
1280x720 60.0
2020x1180_60.00 (0x169) 200.0MHz
h: width 2024 start 2160 end 2376 total 2728 skew 0 clock 73.3KHz
v: height 1180 start 1183 end 1193 total 1224 clock 59.9Hz

I enter:
xrandr --newmode <Mode''Line>
I get:
bash: syntax error near unexpected token 'newline'

Already I see an error message though without knowing what else to do I try to continue the code as follows...
I enter:
cvt 2020 1180
I get:
# 2024x1180 59.90 Hz (CVT) hsync: 73.31 kHz; pclk: 200.00 MHz
Modeline "2024x1180_60.00" 200.00 2024 2160 2376 2728 1180 1183 1193 1224 -hsync +vsync

At this point I see it shows 2024x1180 when I actually entered 2020x1180 which I find odd, though I try the next part with both 2024 and 2020 with same results.
I enter:
xrandr --newmode "2020x1180_60.00" 200.00 2024 2160 2376 2728 1180 1183 1193 1224 -hsync +vsync

I normally get no response after with a blank cursor, though one time I got:
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 150 (RANDR)
Minor opcode of failed request: 16 (RRCreateMode)

Programming :: X Error Of Failed Request - BadMatch?

Mar 15, 2010

I'm working on a old piece of code on linux, after compiling without porblem at the execution I have this response:

src/xproject/xproject: Ok, a color display! :-)
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 78 (X_CreateColormap)
Serial number of failed request: 7
Current serial number in output stream: 15

looking at the source code I think the problem is related at the depth of my system 24 bit and the depth of this old piece of code 8 bit. Unfortunately also I don't have experience in programming the XVideo and if someone can give me some help in programming the XVideo interface

Ubuntu :: X Error Of Failed Request: BadName (named Color Or Font Does Not Exist)

Jan 15, 2010

I just made a fresh installation of Ubuntu Karmic, but I can't set up my screen resolution correctly. My monitor resolution (1680 x 1050) is not listed in 'Display Preferences' or in my card's proprietary software (ATI Catalyst). The maximum resolution I can select is 1440 x 900.xrandr detects a maximum resolution of 1440 x 1440 and displays the same list of screen resolutions as 'Display Preferences'.

But when I enter the line:

xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync

I always get this message:

Major opcode of failed request: 156 (RANDR)
Minor opcode of failed request: 16 (RRCreateMode)

Ubuntu :: Dual Channel Failure & Single Channel Errors

Jun 25, 2011

PC seems to run fine in single channel mode but monitor reports no input in dual channel mode and memtest86+ lists from 1-3 errors per pass in single channel mode. Motherboard (Gigabyte P43T-ES3G) can't be set for the 1.65 volts required by the RAM (2x2 of OCZ3P1333LV4GK PC3 10666). The mobo voltage choices are 1.6 or 1.7 volts. I have tried both and increased the MCH voltage from 1.1 v to 1.2 v, but so far can't get it to run in dual channel mode at all and single channel mode seems to run fine but I still get errors in memtest86+. Also tried optimized Bios settings and loosened memory timings (from 7-7-7-16 to 8-8-8-27 and tRFC 60 to 70) and reset Command Rate from 0 to 2. CPU is Core 2 Quad @ 2.4 Ghz, PSU is rated at 400 watts, Video card is Gigabyte GT220.

Ubuntu Networking :: 'wlan0 Is On Channel -1 But The AP Uses Channel 6' With Airplay-ng?

Jun 29, 2011

I'm trying to crack my wep password just for kicks, but I keep running into the same error. When I try to use airplay-ng for the packet injection, it always gives me the error " wlan0 is on channel -1, but the AP uses channel 6". I've tried setting wlan0 to channel 6 manually, but that doesn't help. I spent a while searching for a solution, but it seemed like each page had a different, usually highly complex solution, that still doesn't work. I have the most recent drivers for my wireless card, and it meets all the requirements. So, is there any solution to this that will actually work?

Ubuntu Servers :: Controlling Files Listed By Directory Request

May 5, 2011

I use Apache 2.0.55 (Ubuntu) as a document server for a business association. When the document files expire, I change the permissions so that only the owner can open them but I like to leave them on the server so that they are all in one place.

Here is my trouble--when visitors come to the site and get the directory listing, all the document files show up, whether the visitor can access them or not.

Is there some way to configure the server to not show the inaccessible files?

I guess a few technical details might help. During their useful lives, the files permissions are set to 644. Once they expire, I change them to 600. After the change, the files are still visible. Setting them to 000 doesn't help either.

It might be of note, but directories behave differently than files. If I set a directory to 600, it disappears from the listing.

Ubuntu Servers :: Trigger A Shell Script Upon DHCP Request?

May 13, 2011

Is there a way trigger a shell script after my DHCP server successfully gives out, either a specific IP address or to a specific MAC address.I have two Xbox360's in my house that both receive IP address via DHCP reservations from the Ubuntu server.I have come to accept that without having two public IP addresses getting both to have an open NAT will be very difficult. I have decided that I am OK with only one being able to have an Open NAT at a time, but I want to change the firewall rules according to which Xbox 360 turned on first. This way I can move between level in my house and play online without having to modify rules manually.

Ubuntu Networking :: Error - Vendor Request 0x06 Failed For Offset 0x3040 With Error -110

Feb 12, 2011

Having a problem with my Belkin wireless adapter when trying to stream music to my Pinnacle Soundbridge.The network connection is usually rock steady but drops anywhere between and few second and a few minutes after streaming music. Network manager still shows the connection to my home network as active but it is not. The connection comes back when I unplug the dongle and plug it back in. I found the following message repeated in the syslog

phy3 -> rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x3040 with error -110

Only thing I have noticed is that it refers to rt2x00 when I had thought it used the rt73usb driver.Had the PC and the Soundbridge for a number of years without any problems but I did recently have to reinstall Ubuntu from scratch. Currently running Ubuntu 10.10

Ubuntu :: Error "wireless Request "Set Tx Power" (8B26): SET Failed On Device Wlan0 ; Operation Not Supported"

Nov 12, 2010

Although Win7 is not bad either, I'm really happy using new Ubuntu Maverick Meerkat on my notebook. Since I've been using Linux (SimplyMepis, then Arch) on my desktop, I'm really happy that I found a Linux distro which suits me the best. BTW, I have a Toshiba T130-10g which I love for its long battery life. However, I would like to solve some issues/dilemmas/questions (and I searched for s the solutions of some of them on Google so please don't tell me to use it...)

1) How do I turn off Wifi completely in a comfortable way? I tried sudo iwconfig wlan0 txpower off but it threw: Error for wireless request "Set Tx Power" (8B26): SET failed on device wlan0 ; Operation not supported. I even edited something in interfaces configuration file, but it did nothing. Oh, I forgot, my notebook doesn't have a hardware switch to turn off wifi.

2) Setting brightness doesnt work for my laptop. I can set it by udo setpci -s 00:02.0 F4.B=25 but I'm looking for a more comfortable solution. BTW, editing one GRUB configuration file didn't help and ended in booting into command line (it was something with adding backlight=vendor or something like that...)

3) My touchpad is sometimes too sensitive and clicks somewhere sometimes when I don't want to it. How to make clicks less sensitive? I tried to play with some mouse settings but it didn't help much but perhaps I'm setting a bad parameter.

4) I remember that back in KDE 3.5 times a network manager icon had a setting to switch on net statistics so I could very easily see how much I downloaded every day. But, since KDE 3.5 is not supported anymore, I stopped using it in refusal to update to KDE 4.XX and switched to GNOME. Since for some months I'll have a limited download connection, is there something esay in GNOME to watch my net statistics that wouldn't be deleted after reboot/shutdown?...
