View 2 RepliesI just narrowly passed another exam on UNIX Academy. Their DVDs are incredible. While I made some mistakes here and there.I was really stumbled upon a question that was formulated something like "SNMP for managing Linux machines remotely".I can't remember the exact definition. I'm not sure what it was about.I was under impression that SNMP it is a carrier protocol for commands like "ping" and "traceroute". I was trying to read about it online but it is way too broad and technical, they're loosing me on very first page. I suspect there's some kind of product or technology that uses SNMP in some way to handle Linux, I'm not sure.
View 2 Replies View RelatedSo I've got a backup server that has a daily cronjob to back up all my systems. My desktop PC is usually in sleep mode to save power. So my backup server has to wake up the desktop via wake-on-LAN to start the backup job. When the backup script is done, my backup server sends a shutdown command to the desktop to put it back in sleep mode.
The trouble is that SSH is timing out during the shutdown process and waits a ridiculous amount of time before giving up and allowing my backup server to move on to the next backup script. Here's the portion of my backup script for the desktop that does the shutdown stuff:
Code:
ssh user@host.lan '/usr/bin/shutdown -p +1'
Here's what cron sends me via e-mail:
Code:
Read from remote host host.lan: Connection timed out
real 164m46.280s
user 5m16.160s
sys 1m39.760s
Normally the entire backup job will only take about 5 minutes. But because of SSH timing out, it takes 164 minutes!
As a matter of detail, my backup server is running Ubuntu 9.10, and the desktop is Windows 7 x64 with Cygwin. The -p option for the shutdown command in Cygwin is for sleep mode.
I am running NFS and NIS servers in my FC8. Clients are also running FC8. Everything was working fine. I could login remotely to server as well as clients. Suddenly (few days ago) a problem started. I can not login remotely to client machines. I did not do anything. I can login to server remotely, but not the client. When I try to login, it accept password and nothing happens. Also, when I try to login from server to client same thing happens. We share the home directory of the server with client. Another question: there two type of nfs server nfs-user-server and nfs-kernel-server. I just use gui to set up the NFS. I don't know which one I am running. Is there any way to find out which nfs I am running?

View 4 Replies View RelatedI have developed a website. Now i would like to monitor the IP address of machines who are accessing the server. The simplest possible solution to this that comes first into my mind is to use jsp inbuilt tags.
Code:
<%
out.print( request.getRemoteAddr() );
out.print( request.getRemoteHost() );
%>
but it has given me some other IP address(May be a proxy server's ip address)
So i was left with one choice is to run netstat on host server . Here is what i have done.
Code:
netstat -an | grep 8080 (As tomcat runs on port 8080).
Should i modify the command or there is any other way around to monitor the IP address?
I have a server at home running as a file server and DHCP connected to a switch with a wireless AP in there as-well. with this setup I can access the files and do some configurations via SSH on the actual server anytime I'm able to get the wireless signal, now lately I felt the need to be able to do the same but this time over the internet. I've read somewhere already that I'm gonna need a router with port forwarding and NAT, then know the IP address of the server but my problem is once you start talking about routers then you need broadband connection which is something I don't have. Getting a router is not much of a problem but without ADSL like connection I guess its useless, what do I need to do?
View 7 Replies View RelatedI setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. I'm assuming I need to be able to connect to my next-server but maybe I'm wrong.

View 3 Replies View RelatedI have a vsftp server running, and we have problems sporadically where people (not the person who uploaded the file) cannot delete files uploaded from OSX machines. We never have this problem with files uploaded by PCs. Anyone ever heard of this or know what I should check? The users uploading the files all belong to the same group. Also, I think if you log in to the FTP server with another OSX machine, it will let you delete them. I'm looking at the folders now, they have drwxrwxr-x. When i try to delete them from a PC, it gives me a 550 Remove directory operation failed.
View 14 Replies View RelatedOfflate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

I guess the completely OFF to ON is much more complicated - would probably require an extra piece of hardware(?)
I'm not terribly new to Linux, but I am new to the forums, so hear me out! I am in the process of creating an electronic mapwall for our meteorology program, and have designed the computing system from scratch. I have two Linux Boxes, each with capabilities for 6 attached monitors...a total of 12 displays driven from two machines. My intention is to have one machine be the master...it has a touchpanel control. The inputs to the touchpanel will then trigger events for the both the master and the slave machine to display. Each of them has a specific IP address (DNS entry), and are not on a subnet.
Now...is there a way to remotely login to the slave machine and have it display on it's OWN monitors? The code is Java and which works on the master machine to animate directories of .gifs for each of the master's attached monitors. I will most likely have Java execute shell commands for the remote login (ssh), but I believe the answer lies somewhere in the X-configuration. Do I have the machines in an adverse configuration (creation of a subnet would be better)? Lots of questions...lots of desire...few answers!

I like to end my X session in Arch on a regular basis. I always use'killall xinit'..This gives a lot of WARNING's and ERROR's. Among the messages are some lines about syntax errors in my config files, I think. But mostly it's about a "Fatal IO error" and gnome-settings-daemon not knowing what session it is in.Is there a gentler way to put X down? Or is this how it should be?I tried killing some of the processes that claim to be interrupted, before killing X, to no avail.

- After some time, the monitor blanks but the backlight does not power down.

View 4 Replies View RelatedThere is a server which was installed 3 days back. It got Cent OS 5.4 64 Bit with 4 GB RAM. Apache, MySQL, PHP and vsFTPd were installed using yum.Server was on the network and approx 100 visitors were on the website. All of sudden server got down. It stopping responding ping. Server guys told that server got down and after a request submission, they restarted server. However reason of the problem is still unknown. I logged in to shell via SSH and checked /var/log/messages file, but didn't find any record which indicate cause of system shutdown. However dates in this file aren't in chronological order.
Is there any way or log file to check for the exact reason, why system got down. One reason could be hardware fault (for that I am going to ask hosting company to run diagnostics). Other reason could be a software/os bug. Is there any tool / log file to check and diagnose the cause.
I try to use fedora 11 as my home server. The server should be remotely managed by VNC. A normal VNC-setup does not allow to log into the login screen, but that is what I need !!
Notice that I would like to maintain the sever using the normal gnome gui. I have been investigating lots of options to get VNC running this way, have been searching all over, but did not find any working solution. All solutions I found where based on XVNC which is not available for fedora 11 as far as I know.
Small home network consisting of a media server(headless, no monitor/keyboard/mouse)running OpenSuse 11.0, and 3 Windows clients running Vista. I don't need the server running 24/7 so I have it set to Suspend to Ram after 60 minutes, which works great. I have a WOL program on each client which works perfectly to wake up the server.
However, there are times when the server "sleeps" while I'm still using it. I can be downloading to the server, playing music, or whatever-doesn't really matter-and when the 60 minutes is up, it sleeps. What I need is some solution that will keep the server awake if I'm actually using it but let it sleep after the specified period of inactivity. My first thought was using Ethtool to wake it network activity directed at the server, but I've tried all the ethtool options and can't make it work right. Either it wakes on any network activity whatsoever, (which means it never sleeps) or doesn't wake at all.
