May 26, 2011
I recently installed ubuntu 10.10 replacing fedora 10. installation was successful but when I start Ubuntu, computer halts showing two line error [18.929065]mpu401_uart:unable to grab port 0x330 size 2 [18.929125]cmipci: no UART401 device at 0x330 Even reinstalling could not solve problem If this is related to audio then in Fedora 10 everything was working fine. But I could start Ubuntu selecting recovery mode with option 'single' then from recovery menu 'boot as normal', providing username and password and typing 'startx'. How can fix this error?

I am thinking it might be internet related. Google does come up with things re the error but I am not clear as to what I should do. WCS 1.8.5b3-Linux is a chat program

I'm trying to connect with my server via telnet, but when i sent the command (telnet xxx.xxx.xxx.xxx Port) doesn't works and shows then follow error: Unable to connect to remote host: Connection refused, It happens with any port. Is strange but my telnet services works (telnet xxx.xxx.xxx.xxx), In addition, i tried with firewall enabled and disabled and the problem still happens. My centOS run on virtualbox.

I'm not that great with mailservers, and just been thrown a curveball with a MS Exchange environment for which there is apparently no solution... yeah, right. But is there a workaround?
The problem is that the site mail (SMTP) needs to be sent via port 26 instead of the commonly used 25. Port 25 is mapped to a mailfilter, which apparently causes havoc with some of the mail, and the techs that have been on site trying to coax the Exchange server to co-operate have said that the only way would be to get rid of the filter.
The problem is that there are number of apps that are unable to have the outgoing port changed and so keep sending mail out on port 25.
I look after the Unix/Linux side of things at work, and I was wondering if there was an easy way to set up a Ubuntu box to receive mail on port 25 and just forward it to the MS box on port 26? So, in other words (and I hope this makes sense): monitor port 25, and forward whatever comes in on port 25 to the server on port 26. Simple portforwarding, or is it? What steps do I need to take?

When I use the following command:
ssh user@ssh_server -L 5500:localhost:5500 -p 22
everything works fine. I can log in, and local port forwarding is done. Otherwise when I use the command:
ssh user@ssh_server -R 5500:localhost:5500 -p 22
I get an error "remote port forwarding failed for listen port 5500". However when I try remote port forwarding in WinXP by use of putty there is no problem...

I'm running Ubuntu 10.4 and I've tried disabling IPv6 as I don't currently need it. I rand the following to disable IPv6 and then rebooted my server:
echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
After the reboot I can see that IPv& is disabled by running:
cat /proc/sys/net/ipv6/conf/all/disable_ipv6
On running netstat -antlp i see that most of the IPv6 applications have closed but SSHd keeps running:
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:9090 0.0.0.0:* LISTEN 663/java
[Code]....
Ho can I close the SSH daemon on port 22 of the IPv6?

So this is my first post so I'll put it in "Newbie".I seem to have successfully configged my httpd.conf file to listen on port 8008. I restarted httpd ok. However, when I go to port 8008 in a web browser from another computer on the internal network by going to 192.168.2.5:8008, it doesn't connect. When listening on port 80, I can browse to the IP address fine. is this a server-side or client-side issue? Using Fedora 12. Thanks in advance and tell me what forum this would best fit in.

Say I have Computer A behind a router with NAT. I'm unable to add any port forwarding rules to that router. Then I have Computer B with a public IP address that I want to forward X windows from. This computer is headless, but does have a video card so X windows can be used. Here are some of the things I'd perform to setup my scenario.
1. Computer B, I'd run xhost + public_ip of NAT router.
2. Make sure that computer B's sshd service has X11 forwarding enabled.
3. SSH from Computer A to Computer B with the X windows forward option.
4. Once in Computer B, set the DISPLAY env variable to the public_ip of NAT router.
5. On Computer B run xclock.
At this point I'd expect to see an instance of xclock originating from Computer B onto my desktop. However this obviously won't work. The problem is that when the request is made to Computer B to forward the instance of xclock to Computer A the forwarded instance of xclock will get stuck at the NAT router. Without a port forwarding rule the NAT router will not know which internal IP to route the instance of xclock.
Here's my question. Is there any way for Computer A to initiate a connection to Computer B and then forward the instance of xclock? That way if it uses that same connection the NAT router will know which internal IP to route it to because it would be an active connection in the router's routing table. Or is there an alternative? Of course I can vnc into another computer outside the NAT network and then forward an X window to it just fine. But in the spirit of expanding my knowledge on X windows I'd like to see what is possible.

Startup script. I have a problem with an error on system boot:
hub 2-0:1.0:unable to enumerate usb device on port 5
This error is continuous, filling up my system logs. It is also a known kernel bug. I found a solution here: [URL] but it is only good after I boot. I have tried to make a startup script in /etc/init.d in the following manner.
sudo mkdir /opt/usb/
sudo gedit /opt/usb/usbproblem.sh
#!/bin/bash
# chkconfig: 345 91 19
# description: stop usb problem on startup
case $1 in
*)
echo "fixing usb problem"
cd /sys/bus/pci/drivers/ehci_hcd
sh -c 'find ./ -name "2-0:1.0" -print| sed "s/.///">unbind'
cd ~
esac
exit 0
#End of boot script
##
sudo cp /opt/usb/usbproblem.sh /etc/init.d
cd /etc/init.d
sudo chmod +x usbproblem.sh
sudo update-rc.d usbproblem.sh defaults 92 20
but it does not work.

Iam using snmp to access the remote system data.But according to the requirement iam encoding the snmp request data to OAMPDU packet format and sending to remote system.the remote system receives the OAMPDU packet,decodes it and is sending the snmp packet to snmp agent through UDP socket which is bind to port 161.but iam unable to receive the response from snmp agent.i have created a udp socket which is bind to 161 port to receive the response.
if i use any other free port number other than 161 for receiving snmp agent is not sending the response to that port.can any one please suggest me how to overcome this problem.Can we configure the different ports for tx,rx ?How do we know on which port does snmp sends the response ???

I'd like to take audio track from a video clip in FLV container and save it to something playable by portable music players. Are there any easy to use tools for that? I know how to do that using console tools (mplayer+lame/oggenc), but I'd like to get something clickable, preferably for GNOME.

I'm trying to get an output of a file in numeric order. Basically I need the starting number and the ending number in sed this into anther file. The test2.lis file I'm just awk'ing for the first row and if its out of order put it in order so I can grab the first and last numbers. I'm sure I can do this all in an array. The first sed command gets rid of blank lines and outputs it to a file. Then I head and tail for the first and last number then I want to sed those numbers into a file that exsist.
[code]...
The error I get is:
sed: -e expression #1, char 24: unterminated `s' command.

I'm writing a script that picks out the time offset in a string, but am trying to figure out a way to print a field based on a match (likely needs to be regex).
Here are some sample fields:
09.900. Either add -12:-1: 0 to existing offset, or restart the slicer with no offset or with offset=00
09.900. Either add -12:-1:30 to existing offset, or restart the slicer with no offset or with offset=00
09.900. Either add -10: 0:-47 to existing offset, or restart the slicer with no offset or with offset=00
What I need would be "-12:-1: 0" from the first line, for example. I was just using "awk '{print $4}'" originally but because of the damn space in the 1st and 3rd lines by the 0, that doesn't work for me. How to grab those fields correctly for all cases?

- I setup port forwarding of openssh :
connect 1: ssh -g -f -p 11111 -i /<path-to-private-key> user1@ip-server1 -L 22222:ip-server1:161
- Then I setup second connection
connect 2: ssh -g -f -p 11111 -i /<path-to-private-key> user1@ip-server1 -L 22223:ip-server1:3306
- Openssh waring to me "bind: address already in use"
- So I think port 22223 have had another program use,I use command:
ps aux | grep ssh /* find process id of second connection */
kill -9 <process-id-second-connection>
netstat -an | grep 22223 /*find which program use port 22223> */
- but I can't find anywhat
- Then I run again command :
connect 2: ssh -g -f -p 11111 -i /<path-to-private-key> user1@ip-server1 -L 22223:ip-server1:3306
- And I receive a error from OpenSSH :" bind: address already in use"

I have a huge log file of around 3.5 GB and would like to sample random sections in the middle of say 10 MB for the purpose of debugging what my application is doing.
I could use head or tail commands to get the beginning or end of the file, how can I grab an arbitrary portion from the middle of the file? I guess I could do something like head -n 1.75GB | tail -n 10MB but that seems clumsy and I'd need to determine line numbers for the midpoint of the file to get 1.75GB and 10MB line counts.

VERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.

I have setup an OpenVPN server on my server box, it had been working perfectly until today. It operates on port 1194 which I am now unable to connect to (tried telnet). I have checked all the firewall rules and they still allow the port and I have also checked to ensure that OpenVPN is still listening to the port, which it's not but I have tried restarting the service and the box which dosent make any difference. The only thing that has changed is that yesterday I installed Openfire, could this have broken something?
