View 2 RepliesI've been trying to set up a CLI media player that outs to Coax. So far I have VLC (-I ncurses) working in analogue via the on board sound. Is there a vlc config file or some other CLI media player that will allow me to output via coax? Or can I set my default sound in ubuntu server? ( Note: I don't want streaming, I want local sound from the server.)

It now works well except that it is slow searching for new servers eg, going to facebook creates a long wait and can even time out but once on the website everything works fast, The connection is 2.89 Mbps which is good for this area and ping is 45ms. What could I do to fix this problem. This affect my ubuntu computer and the windows xp pc as well
View 2 Replies View RelatedI have HP Pavilion laptop with two jack outs for audio and both of them work if only one is plugged in. If both of jacks are used, then in only one headphones set there is a sound. I would like to have sound on both of them, so for example two people can listen the same thing on their own headphones.
I'm working on Ubuntu 10.04 and my sound card is:
Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
I cant send mail outs. I'm receiving

When try send mails from pop3/imap or directly "root]#mail some@domain.com" but I CAN send mails to domains created in the server.
I stopped Iptables and still the error. The server is a common WHM/Cpanel installation with Centos 5.
Connection closed.
I have an Ubuntu machine, with an on-board sound card. One of those with about 5 output jacks (green, blue, red, black, pink). As far as I know, there are defaults as to what goes where, like black=center, red=line-in, etc.
How can I change what goes where? let's try the easy case, that all play the same output or that it's stereo and red=right blue=left?
I was reading a bit and was hoping it was something to do with .asoundrc, but got lost there
aplay -l output:
Code:

I am new to fedora, but not so new to linux. I've got f13 installed on my netbook, and the speed and overall beter-ness? of it made me want to get it going on my desktop. I've installed, and have updated the kernel, and network manager (Along with a few other things). My problem is this; after about an hour or two I get a drop out, unable to reconnect. Until I use 'ifconfig wlan0 down > ifconfig wlan0 up' then it works great for about 10 minutes, slows down, and eventualy drops out. i updated networkmanager in the hopes it may have been that, but it really made only a slight difference.
iwconfig :
$ iwconfig wlan0

View 1 Replies View RelatedSet up my mom with Ubuntu and want to be able to connect to her computer remotely to help her out when she has a question. I did some search and it seems that everyone recommends using openSSH. I used this link [url]
To install it on my mom's computer (changed the port to 16 instead of 22 and added those lines he suggested to the end of that file). Now what? I can't seem to find any instruction to connect the two computers. Looking around I also found:
1- Remote Desktop Viewer
2- Terminal Server Client
under applications/internet and
3- Remote Desktop under preferences
It looks like I can use those to connect also. But are they related to openSSH? Should I uninstall openSSH and use 1,2 or 3? Which is moe secure or are they the same.
I just setup Ubuntu 10.04, and immediately installed OpenSSH using synaptic. I edited the /etc/ssh/sshd_config file e.g. no password authentication, non-standard port, etc. Using /etc/init.d/ssh restart I restarted the daemon, and everything worked perfectly. However, now it's almost like there is a lock on my service somehow. I edited the config file and added "PrintMotd no" and "Banner none". I killed all my active ssh sessions, restarted, and still saw the motd and the banner.
I then tried sudo /etc/init.d/ssh stop. The script reported ok, but netstat reported sshd as still listening on the port I had defined. I could still login. At this point, I don't know what else to do. I have tried looking at auth.log, I don't see anything funny there. I tried rebooting, and the config changes are (apparently) not loaded, I still see the motd upon ssh login. This is a totally clean system so I don't know what I am doing improperly.
I had to compile openssh so I could have a version with the HPN-SSH patch applied. The compile seems to have gone fine, but oddly enough I have now have no ssh script in my /etc/init.d directory. So I have no easy way of automatically starting openssh-server.Here are the configure options I used when compiling openssh:
Code:
./configure --prefix=/usr --sysconfdir=/etc/ssh --with-pam
I'm having problems getting openssh server to accept connections in Ubuntu 10.04.Here's what I've done (twice): Installed Ubuntu 10.04 on USB drive with pendrive installer. This creates a default user "ubuntu" and you don't get the chance to choose a password for it. Started a keyring for network access and selected password. Works.Enabled VNC and selected password. Works fine with VNC client on local network. Logs in as "ubuntu" user and asks for the VNC password, then connects. Note: the client doesn't know the "ubuntu" user password, and neither do I! However, it works.Installed openssh client and server from Ubuntu s/w center.
$ ssh localhost OR $ ssh ubuntu@localhost try to connect, but asks for password, which I don't know (see step one, above) so, then I created a new user, with known password, logged in as new user in Ubuntu, works.however, $ ssh newuser@localhost still fails, even when correct password for <newuser> is supplied. Rejects the password three times, then gets the usual error about keys.I also tried connecting with an SSH terminal app from my iPad, again using <newuser>. It gets essentially the same error, "failure to authenticate".
All this is still on my own LAN, haven't gotten to going outside the router yet.What I want to do in the end is use VNC over SSH from a client on my iPad to talk securely to Ubuntu while I'm traveling.
I have Ubuntu 10.04 and I used my ssh to connect to a webserver. This is the version that I have installed.

Apparently the server was hacked using my user and the server admin suggested the my ssh can be tainted.
do a checksum of the ssh, but I cannot find this file on my system.
Code:
md5sum /usr/sbin/sshd
And I will need a md5 hash from a good untainted version and I cannot find that as well on the openssh website.
When ever I try to sftp or even ssh into my server I get connection refused.
I have the port forwarded in my router.
What am I missing?
Also I have installed Ngnix so what do I need to do for it to work?
What was the equivalent apt-get command for installing LAMP and OpenSSH in Ubuntu 10.10?

I would like to upload files via ftp or sftp to my web directory at /var/www/...
Originally I had installed openssh-server (through apt-get, before learning about tasksel). I assumed this only had ssh support and not ftp, so after a quick search, I installed vsftpd. I would like to learn how to configure openssh, and I mention vsftpd in case there is a conflict.
Right now I am able to log in to my server box through ssh/ftp, but I can only modify my home directory. I created a directory: /var/www/andrew and set permissions to drwxr-xr-x. I am unable to upload files to this folder.
What do I have to do to resolve this, and is there anything else I should know about my situation?
I have an OpenSSH server running on Ubuntu 10.04, and it works fine.
I'm concerned that my SSH key may have been compromised and would like to replace it.
I tried replacing keys before and reinstalling OpenSSH and SSH before but ran into terrible trouble so I'm asking for instruction before touching anything this time.

So can I just synpaptic 'fully' uninstall SHH (although probably even less necessary than..) and OpenSHH, backup sshd_config, delete the two dirs referenced above, reinstall both packages, insert my sshd_config backup, and then start from scratch following the guides linked below?
I now have my ssh server all setup on my ubuntu 10.10 machine and properly working with a private rsa key. Anyway when I connect to it via my client it opens to: /home/myusername
I am able to run around the whole drive and have full access to everything, which is great. But I don't have anything on this hard drive. All my data and files that I really want to access are on the second drive of this computer. It doesn't have an OS on it, just files.how to change the directory to point to that drive and have full access of everything.

View 4 Replies View RelatedI'm running Ubuntu 10.04 LTS and I have installed openssh.I need to find a way to configure it so that it never start up when I boot into my computer. The reason is: I haven't had the time yet to learn how to set it up and configure it correctly. Until that time comes I don't want it to run at all.Every single time I boot into the system and I have to do that first before I can even do what I really need to on the computer. It's annoying.Does anyone know the best and least complicated way to just make it not run at all until I'm ready to set it up properly?Also how to check what is running on my system after I boot up so I can double check, after making the changes, that it worked right.

Connecting with PuTTy works fine with my public/private keys. But why does sshd start and then restart twice when booting? I tried looking in the logfiles under /var/log/ for anything with ssh/sshd but nothing shows up.

When I connect with my vps server through openssh, doesn't establish connection. Openssh is active (see its status), port 22 is open, the sshd_config file is the same of original copy (I have saved one in the case I did a mistake) the only line different permitrootpassword is set on ''no'', there isn't a firewall that block ssh connection and with other remote desktop control like remmina works well.

View 5 Replies View RelatedI am running Ubuntu (Karmic) and did the command: "sudo apt-get install ssh", In an attempt to download, install and setup OpenSSH. This installed both the client and server and during setup actually brought the daemon up and running as well. I then attempt: "ssh <myusername>@localhost" and it prompts me with a password. I enter the password, hit enter and immeditaly see the following results:
Read from remote host localhost: Connection reset by peer. Connection to localhost closed. I'm fairly certain that it is not on the client end as I can connect to other machines through ssh. I've tailed all the logs, messages, dmesg etc and nothing seems to be out of order, or even remotely related to shh or connections etc. My desktop machine had no (as in zero) issues installing and setting up OpenSSH, and connections can come and go as normal.
