Ubuntu Servers :: Server With Planned Short Uptime?

Jul 27, 2010

I've installed Ubuntu server on a small box with a couple of large hard drives to use as a remote backup server. Since my backups will run nightly in the wee hours, I'm configuring this to use Wake-on-LAN to start the server and run the backup. Once the backup completes - probably on the order of an hour later - another script shuts the server down. Once in a while I'll remote in to update packages and check on the status of the system, though I can check backup logs to insure that is still running.

Need I be concerned about the various cron jobs that periodically run to tidy things up? Should I periodically - say once/month - leave the system up for a full day to make sure that everything that needs to happen will run?

Ubuntu Servers :: Mail Server Will Not Receive Emails After Uptime Over One Hour?

Jan 12, 2011

It is the strangest thing. I can not receive emails on this server after it has been up for an hour. I noticed that everytime and email is received that a sshd opens but never closes. Causeing a memory issue that I dont know how to fix. Also the mailq grows and grows. Mostly with email stating the recipient and send are both [URL].. also postmaster@mail.jmchd.com shows mail system configuration error. I have to restart the server every 30 minutes so users can get and send emails. This is horrible because for every 5 minutes out of the hour emails are bouncing.i have looked through them but I know not what I am looking at.

PS. I was thrown into the position and have limited knowledge. I am used to a GUI.

General :: Feedback Requested On Planned Multiple Filesystem Copy

Jan 14, 2010

I am going to be involved with a massive filesystem copy from a local to a remote server in the next couple of weeks. There are ten filesystems in involved in this process. All, except one, are one hundred gigabytes in size, with the remaining one at twenty gigabytes.The cp command with the -pr options will be used to copy the directories to their new location. A speed test, involving ten directories, was done to determine the average amount of time it would take to complete the process. The ten directories used in this test ranged in size from 2.3 gigabytes to 4.3 gigabytes. The results indicated the average amount time to complete the copy was around one minute and thirty seconds.

The question I have is the following: Is it better to interactively go to each filesystem and run the cp -pr command there, or should I write a script that will automatically go to each filesystem and run the copy?

Server :: DNS Not Working With Short Hostnames

Jul 20, 2010

I have changed some settings on my DNS / DHCP config under Debian Lenny, and now when i try to ping some box it only works with long names.

For example:

Ping borsti doesnt work (can not find host) but if i use ping borsti.borsti.iss it works. I have no idea why it doesnt work because i only modified the dnssec-key (created a new key) and nothing else in te config Here is the config i used for bind: (taken from named.conf.options and named.conf.local)

And here is my dhcpd.conf:

Debian :: GNU - Resets It's Uptime Every 497 - 498 - Days

Sep 10, 2010

I've read from some Web-page that GNU/Linux resets it's uptime every 497 (498) days... So even if GNU system works 1000 days, uptime never will be more then 497 (498) days. Is it true?

Debian :: Silent Lenny After 1-3day Uptime?

Apr 14, 2010

This seems like a nicely populated forum so I hope some knowledgeable people happen to see this thread.

I've been encountering this issue where the system will not respond to seemingly anything after being on for generally no shorter than a day but sometimes as long as three days. This has been going on for few months since I only have physical access to the machine for about a day or two once every two weeks. So I'll come to the machine, reboot it, it will be fine for a day; then about a day after I'm away from it, it will not respond in any way. When I am away from it I only have ssh access, but when I'm with it, I have access to anything and everything.

After it locks up into the silent issue I have tried: ssh either remotely or locally, where it will time outPinging from the local network, where I get "ping: sendto: Host is down" a lot and occasionally a "ping: sendto: Host is down"Plugging in a monitor and keyboard, where the monitor never gets a signal no matter what I do on the keyboard. When it isn't locked up into the silent issue and I plug in the keyboard and monitor, the monitor gets a signal right after I hit the spacebar for sure. After the silent issue triggers it's fans still whir, the power light is on and light on the Ethernet port is on (and turns off if I unplug the Ethernet cable, and back on if I plug it back in) like everything was normal but there is no hard drive or network activity (even after unplugging/replugging the Ethernet cable).

After a reboot, all log files have nothing past a certain time and date, which I assume is the time when the silent issue got triggered. My setup is the following: Debian 5.0 "lenny" on an HP ProLiant ML110 G6Using full disk encryption with ext3 which was all set up by the installerIIRC "core" and "minimal" were selected in tasksel during install. I'm sure about "core", not about "minimal". The programs I have running are apticron, ddclient, sshd, fail2ban, screen, php-cgi (php5-cgi), cherokee (from unstable) and rtorrent (from unstable). I can provide a "ps aux" if necessary. The packages from unstable, that I have all set to Pin-Priority 990 in /etc/apt/preferences, are:

[Code]...

I'm pretty sure I don't have ECC memory so I don't think a lockup from a flipped bit is an issue. I'm thinking one thing to test would be to set up some kind of daemon that sends log info over the network to a logging server and compare the latest timestamps of what the daemon sent versus what the latest info on the disk is, and that would show that the issue is with the encrypted disk since things are still functioning in memory but not able to write to disk. If that's the case then I guess it locks up eventually from not being able to read or write something. Does anyone know of something out there like this? Or perhaps a way to do something similar?

Is there something I could do to determine whether this is caused by maybe some kind of kernel panic or by something like the motherboard having issues?

General :: Uptime - Getting Date & Time Of System Startup?

Mar 28, 2011

I know that uptime prints the time a machine has been up and running, but is there an easier (reliable) way to get the date of the start up than counting down from this output?I tried looking around /proc, but didn't find anything of relevance. There's also a line like this on my dmesg: [ 0.673492] rtc_cmos rtc_cmos: setting system clock to 2011-03-14 14:26:52 UTC (1300112812), but I'm wondering if this method is distribution and kernel version agnostic.

General :: Difference Between System Uptime And Last Boot Time?

May 11, 2011

My Linux system was last rebooted few hours ago. But it seems little confusing for me to figure out the exact reason behind it. I guess following command should justify what i meant to say.

Code:
# date
Wed May 11 13:22:49 IST 2011
# last | grep "May 10"
reboot system boot 2.6.18-194.el5 Tue May 10 17:35 (19:46)
root pts/1 XXXX Tue May 10 17:24 - 18:18 (00:53)

[Code]...

My question is Why the uptime is saying that the system is up since last 47 min.It should be more than 1 day if i m not wrong.

Ubuntu :: Password Is Too Short Error

Jun 27, 2011

I have been trying to change my password on this install to a simple 2 character alpha.

I tried using the "users and groups" menu and got the error "password is too short" that also tells me that I need more that 5 characters.
After searching for a bit I found the passwd <username> command to be used in the recovery mode. I got a similar massage there too.

upon doing a fresh install I am able to initially set a simple password to do what I want, but after changing to a more secure password I have not yet found a way to get back to where I want to be. I really don't want to burn this down do yet another install.

yes, I know the system is trying to protect me from myself but that is off the point.

Ubuntu Servers :: Windows DHCP Server - Multiple Boot Servers ?

Apr 1, 2011

I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.

These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

From: [url]

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.

1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?

2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
