Software :: Chrony Configuration - Client Only Force Update At Startup?
Mar 2, 2011
I am trying out chrony as a replacement for openntpd as there is no longer an openntpd package in Debian Squeeze. Two questions:
1. Is there a necessity or equivalent to openntpd's "-s" option, where it forces the system's clock to the network time on daemon startup, regardless on how great the clock is off?
2. How do you configure as a client only, not as an ntp server at all? By default, it listens on UDP 123 and 323 (both ipv4 and ipv6) and definitely acts as a network time server (I can query remotely). I do not see anything obvious in the docs. Openntpd by default ran as a client daemon only.

I recently started using Ubuntu 11.04. Everything works fine with my monitor directly connected to the computer. I get a default screen resoluton of 1680 x 1050, which is just fine.
However, when I connect the screen through a video splitter to be able to use a beamer, the screen resolution defaults to 1024x768. Moreover, Ubuntu then detects an unknown monitor and I cannot select a higher resolution.
I searched for modifications of xrandr en xorg.conf but I have to admit I don't understand what I've read. So my question remains: how can I force Ubuntu 11.04 to start with a screen resololution of 1680 x 1050 (without first connecting monitor only, that is).
I hereby add some information I retrieved with the screen connected without the splitter, so you can see what hardware is involved.
Code:
dirk@LaboFysica:~$ xrandr
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192
VGA1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm
1680x1050 60.0*+
1280x1024 75.0 60.0

I just downloaded Thunderbird 3.1.4 and I think I found a security hole.
Whenever I open Thunderbird, it does not ask me to authenticate my account (not asking for a password)
Is this a bug/security hole or something?
How can I force Thunderbird to ask me for my gmail password at startup?
Oh!!! and where can I report this security hole?

I started using Ubuntu 11.04 today.
Everything works fine with my monitor directly connected to the computer. I get a default screen resoluton of 1600 x 1280, which is just fine.
However, when I connect the screen through a video splitter to be able to use a beamer, the screen resolution defaults to 1024x768. Moreover, Ubuntu then detects an unknown monitor.
I recall that I have solved this problem before with an older version of Ubuntu.
Now it seems that there is no xorg.conf anymore so I don't know what to do.
How can I force Ubuntu 11.04 to start with a screen resololution of 1600 x 1280.

In my case I have TeamViewer 6 (remote desktop application) opening as one of my Startup applications. I only really need it to run in the background, so I don't need it in my face after logging in.
What I'm looking for is a command line option for opening an application in a minimized state. Is this possible? Or should I start looking into a script to find the window and minimize it?

I use chrony on my laptop thinking it would be better for it than ntp because I'm frequently connecting and disconnecting from wireless cafe access points and going in and out of suspend mode. But I've also noticed that if chrony is started before the access point is connected it never syncs to the time servers. I have to manually restart it via the service command after I connect. This doesn't seem right to me, if chrony fails to find a network at start time, doesn't it periodically try again ?

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

I actually have a server and a client.The client must connect to the server (via internet) to access to external websites. (You can see the attachment, maybe it's more clear )My actual problem is, I have configure Squid on my server, but I want to force SSL for the connection between the client and the server.I didn't really find nice tutorials about on that, maybe someone have an idea ? Or maybe some indications ?

I was working on my flash drive install of Ubuntu, when I squashfsed my /usr. Long story short, I some how ended up with a working /usr, but with a few packages marked as installed, but not having its components installed (emacs). When I try to remove emacs (emacs23-nox), it gives me numerous errors about files (all relating to emacs) not existing (all in /usr). Thus my questions are as follows:
1) Is there a way to force the removal without it caring about missing packages?
-OR-
2) Is there a way to reload which packages are installed by checking which files exist, etc?
-OR-
3) Should I just nuke and re-install?

I forced the install of graph-tool package [URL]. Now it is of course tagged as broken, so update manager wont do anything. But I want to accept it, I know it is not really broken. (In fact, graph-tool_xxx.deb asks for libcgal4. squeeze only has libcgal5, so I am betting this is not an issue, as far as graph-tool is concerned.)

My Debian workstation is on a predominantly Windows network. It is resolving internet addresses (i.e. www.google.com, etc) just fine. However it's not resolving any of the address of machines on the local network and the windows machines do not resolve the linux machines address either. All machines (linux and windows) can access each other just fine via direct IP reference.
My /etc/resolv.conf file has the following IP addresses listed:
127.0.0.1
10.1.1.111
10.1.3.4
10.1.1.111 is a netgear VPN/router that is the primary router for the LAN and maintains a VPN to a remote office 10.1.3.4 is the IP address of the Windows Primary Domain control on which the DNS server is running. That server is at the remote office. The system acts like it is completely ignoring anything I put in the resolv.conf file. From the linux X server I'm using "Network Setting" utility to make changes to the network configuration. This appears to work fine for things like switch between DHCP and static IP.

I'd like configuring NTP service on my Lenny Debian client to retrieve time from my local NTP server, so I thought to configure /etc/ntp.conf and to insert into crontab this command 'ntpd -qg', which is indicated in man. Can I run ntpd service to synchronize time for my client, avoiding to listen on port 123, beacuse my scope is to alignment time on client and to not give service to others, for this scope there is ntp server !

I have Debian 7 running on RPi2 with Kodi. My NFS server is running on Slackware 14.1 which doesn't have full support for nfs4. I think this is causing some slowdowns/extra time when trying to stream video. Debian 7 by default mounts NFS as nfsv4, I would to like to disable this if possible. If so how?

I have installed mpd on my Arch box and it starts correctly with "/etc/rc.d/mpd start" My clients (ncmpc,sonata and gmpc) connect. My problem is that I can't update the client - at least when I try I only get a partial update. I have around 5 gb of music but only 3 albums appear (2 different artists.)
My mpd.conf has the following:

configuring my postfix server to send mail over smtps port 465. My ISP (as is the case with many ISPs), is blocking outbound SMTP, so I need to configure postfix to relay my mail out through my ISPs SMTP servers.
I was able to get it to work with gmail, which uses port 587, by using SASL: [URL] but that configuration is less than ideal as gmail drops the "reply to" address so when people receive my email, it looks like it's from gmail instead of from my server.
If I use my ISP SMTP servers as a relay the "reply to" address is not stripped, but the relay uses ssl over port 465 instead of TLS. According to the SASL readme:
Quote:
Postfix does not deliver mail via TCP port 465 (the obsolete "wrappermode" protocol). See TLS_README for a solution that uses the "stunnel" command.
I've looked at the TLS_README and can't figure out what I need to do. how to configure this?

I'm running a Ubuntu 10.04 server in a secured zone on my network that has no access to the outside world. In that same zone, there is an NTP server which I setup my Ubuntu server to access in order to sync its time on a daily basis. Everytime I reboot my Ubuntu server, the clock goes back 4 hours, I guess since it cannot access the default Ubuntu NTP server. Is there a way to disable this from the startup and if so where do I do it, or can I set it to sync on startup with my NTP server?

I tried recompiling a new kernel yesterday (2.6.34) on my debian sarge box, but I ran into multiple difficulties. These difficulties forced me to do a double dist-upgrade to lenny. The new kernel was (seemingly) compiled without any hiccups, and I ran dpkg -i on both the image and the header debs. They didn't install properly into grub, but I think I managed to fix that manually.Next thing I did was rebooting the server. It refused to come back up. Luckily my ISP has recovery tools, so I managed to switch back to the old kernel. It boots just fine with that kernel, but the problem is that there is no ssh daemon running! I can access it through ftp and do limited jobs through php, but nothing big, as I have no root access.Now, enough backstory. My question is: How can I install openssh-server onto the server remotely? I cannot access the server personally, as the server is in a completely different country.

I've been trying to setup Plymouth on Debian Squeeze, but have only been partially successful: Plymouth works with shutdown (i.e. I see Plymouth after I tell the computer to shut down), but not when I start up my computer (before it reaches GDM). In other words, Plymouth seems to work with my graphics, but for some reason does not show up at startup (not even briefly, as far as I can tell). I've searched the forums and followed this advice, as well as the instructions found here: [URL] but neither of those worked. I'm running Debian Testing (Squeeze) on a Thinkpad X41, which uses "Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller" for graphics.

I've been using Debian since the early days of Lenny being testing as OS on the same Computer. Its a Acer Aspire Notebook with switches for wireless and bluetooth. While booting Lenny my wireless and bluetooth stayed off as long as I didn't switch them on. But since squeeze they get activated ( you can see it by looking at the LED's ) the moment after the grub screen. I now do have to turn bluetooth and wireless off by hand everytime which is quite annoying since I mostly use eth0.
how to disable bluetooth and wireless per default in a way I can simply turn them back on by using the switch?

I installed the latest Debian on a computer to make a backup appliance. No GUI.When the computer starts, everything is okay. The DHCP client is running, the network interface have an address, fine.If I do a /etc/init.d/network restart (or stop + start), no more DHCP client. t is stopped when the interface is down. When the interface is up, I have to start it manually.1 - is it normal ?2 - isn't ifup's job to launch the dhcp client ?3 - can /etc/network/if-up.d be the right place to resolve this ?

Since last few weeks i am struggling to setup printer connected to print server.
Here is the setup that i have:
I have Red Hat Linux machine from which i want to issue print jobs.
I have Windows Print Server having multiple printers connected to it.
I am able to print jobs from Windows client to any of these printers. But i am not able to print from Red Hat Linux. (i have verified that i can print using smbclient utility, but based on my reading, CUPS API could be used from application to discover, print and issue print jobs.)
I am not able to get the correct configuration for setting up CUPS client.
