HP's apparently all but useless Linux site suggests that their hplip drivers give you that capability. However, it also seems to expect that I will be running a GUI to use their tools.
My CP-1215 is attached to my server which doesn't have a GUI installed.
Previously I'd been using the open source CUPS driver, which seemed to work pretty well. However, I recently ran low on one colour of toner which messed up the printing. The toner-out lights on the printer never cam one, so replacing the toner cartridge was not the first thing I tried to fix it.
I've just installed the hplip / hp-plugin driver which also seems to be working. However, the CUPS web interface doesn't allow me to retrieve the toner status.
Has anyone had any luck retrieving the toner levels from an HP colour laserjet printer?

I have set up a user to login remotely to our Red Hat 5 server via SSH. A rule in our department firewall enables this user to login from a single static ip address. The ssh port on our server is 22. I am able to login to port 22 from locations within our department firewall. Our administrator says the firewall configuration is unchanged. The remote user had been successful logging in. But now the remote user gets a Connection Timed Out message, before being asked to authenticate by the server.
I regenerated security keys, but the remote user still gets the connection timed out message. (I can login locally with the new keys). I suspect either a firewall or an authentication problem--inclining a firewall problem. Am I correct? Is there a Linux command to check whether port 22 is available or blocked, prior even to authentication, for login from the user's remote location?

I have a F11 box serving xdmcp. I log into them machine remotely with xming. As far as I can tell, all x clients work fine, EXCEPT for sealert. I get occasional selinux alerts, but I cannot use the sealert browser on my remote machine. When I try to run the browser, I get this: sealert -V -b

I see the bug at [URL].. but it does not mention the browser, nor does it say what the fix/workaround is..Im going to stab in the dark and start relabeling things, but anyone know what's really wrong?

I am using debian testing on my office pc, but i need to access it's desktop from time to time. So i need No machine/teamviewer software that can provide me with possibility to interact my desktop. The problem is, that i want to run shadowed session type, because teamviewer is not good for me. So, when i run no machine in shadowed mode, it crashes with message "The connection with remote server was shut down, please check your network settings and try again." The log is here:

I'm using iptables with modules ip_contrack_ftp to be able to use passive ftp. It works well as long as port 21 is being used as listening port. Is there any way to make it work when I configure my ftp server (vsftpd) to listen on an alternative port, lets say 21001 or something? The helper module only seems to be working properly with the standard port, so I was wondering whether there was a way to "tell it" that another port is being used? I mean, of course I make a rule in fw to allow traffic to the alternative port.
But once it's time to start passive connection, then the iptable module cannot handle it properly. I could solve the problem by making a range of passive ports in the ftp-server configuration and allow the incoming traffic to them, but then using helper modules doesn't make any sense. I just want to allow the traffic to the listening port and then want the ip_contrack_ftp module to take care of the rest. This is what I do today - but only port 21 seems to be working. Is there a way to do this with a non-standard ftp port?

I always use VNC to check my server for updates, and this morning I started the xvnc4viewer to vnc into my server and it keep asking for a password. I never setup a password because I do this local from my laptop, and I am the only one who uses my laptop. I had to go to my server and check the setting in System > Preferences > Remote Desktop and found them all changed. There was a password setup and there was a check mark in the you must confirm each access to this machine there some security update that changed all these setting? Sometimes when I do updates I don't know what is being changed on my server

So I've read a bit and it seems that this is okay and secure. But I wanted to double check here with everyone, because I trust here more than just about anywhere. I've read about the hipporemote (which is pretty cool) and I have it working. Basically I want to make sure my system is still secure.
1. I had to open a port on my firewall for the VNC connection.
2. I turned on the Remote Desktop
2a. Checked Allow other users to view....
2b. Checked Allow other users to control....
2c. Checked You must confirm.....
2d. Checked for password, and put in a password
2e. Checked Configure network automatically to accept connectios
So with doing all of that, am I ok? I think so, especially since it says its only accessible on my local network. But I just wanted to hear from people who know more than I do that I don't need to worry any more than normal about others accessing my machine. I'm mainly thinking 2e, I don't fully understand what's going on there.

I have a VPS by my host running on a linux server, and they have given me SSH access. Is it possible to remote desktop into the server, like you can on Windows, so that I can physcially click on things rather than having to use SSH commands?
Surely this must be running on Fedora or Ubuntu etc. so there is some type of OS. You would probably have to install something on the servers end I suppose but just want to know if its possible and what the options are.

I'm wondering if it's possible to control a TTY on a remote machine via SSH. I'm aware of ssh's -t option, but it doesn't seem to do what I want. Basically, I'm thinking in terms of VNC-like operation, where the remote user and local user see the same thing, only instead of a GUI, they both see TTY1 (or 2, or etc). Is that doable, or no?

I have looked for clues in the sshd.conf etc. But I can't really find anything that give me a hint of why fedora 14 keeps blocking my access.I get all the way into the ssh interface.
login as: xxxxx
xxxxx@xx.xx.85.216's password:
Access denied
xxxxx@xx.xx.85.216's password:
Access denied
xxxxx@xx.xx.85.216's password:
So it's not a firewall problem and the port forwarding is working fine. I am using putty to access the machine remote.Anyone have any ideas of what I need to set in ssh or sshd.conf. I am expecting to login with password not with keys.

I cannot remote desktop to the Debian machine from anywhere,hether within the same network, or on a different network elsewhere. Also, the personal wiki I set up on it to be viewed via a normal web browser cannot be accessed, either. Both time out when attempting to connect to them. I can still ping the Debian machine when on the same network, though.
This started some time ago when we had a failure occur on our main server.had to powercycle everything in order to restore things back to normal, the Debian machine included. Since that time, this problem started to occur. This is a major thorn in my side in attempting to prepare for our website to move,I've been unable to figure out how to fix it.Originally, I thought it would be something in between the Debian machine and anything else, which would mean something like our firewall box or our hardware switch was the problem. But the tech support people who maintain those for us confirm that there is nothing wrong with them, so now I'm not certain anymore.
