I'm getting this error whenever executing the top command in Linux remotely via SSH: top: Unknown terminal "dumb" in $TERM
My Java application which monitors the performance of the remote machine uses the output of top command.
I need to set both my font size and my term ($TERM=vt220) from the command for a /usr/bin/terminal. Is there a way for me to do this?
View 2 Replies View RelatedWhy isn't there a simple program like Microsoft Windows' Notepad? One which is format stupid (ASCII only), so I can over-ride hidden html character entities. The other day I found myself wasting hours trying to get the Xephyr to work by cutting and pasting the terminal instructions from the following website into a gnome-terminal session - but each time it would give me the same, small window. I tried copying the text from the browser (using copy and paste) to gedit, but gedit was not showing the hidden character entities from the html code. After all this lost time trying different resolution sizes, I became suspicious that something was interfering with my cutting and pasting between gedit and the CLI terminal. Sure enough when I compared the webpage source code it gave me the clue to the problem.
From the same page - two examples:
Hidden character (notice the '�' or × )
$ Xephyr -ac -screen 1280�786 -br -reset -terminate 2> /dev/null :2 &
NO hidden character (notice the 'x')
$ Xephyr -ac -screen 1280x1024 -br -reset -terminate 2> /dev/null :1 &
[code]....
I even tried cutting and pasting out of the terminal yet somehow it retained the hidden characters. I could not find any preference setting in any of these programs which would allow for either eliminating the hidden characters doing a cut and paste or at least revealing them. I would like to plead to programmers out there for this basic functionality...

Now if you got yourself a machine which bios cannot boot from your 16 giga stick, wouldn't it be possible to use linux as kind of a bootstrap, install it on a 1 giga medium, that the bios can boot from and then when the linux kernel is running, give control to the other media that you really want to boot from. This should be doable.
It is basically going from a running kernel and its inird to give control over to another grub or syslinux. Does anybody know if this exists already? Truth is that many bioses are just garbage, old and fail at pretty much all new hardware, so why not use a linux kernel as a crutch, to get away from this old piece of junk? I did similar things already with a software raid, where i had a machine that couldn't boot from a HD that was larger than 150 giga.
I installed a 10 gb HD to put /boot on it and then give control over to some "fancy 21st century technology that can boot from this HUUUGE disks" (as from my dripping from sarcasm voice you can tell that pretty much all BIOSes are a thorn in my side and a P.I.T.A. for me, too often they only do 30% of what I expect them to)

Most of the time I'm asked to deploy a generic Windows server, install a few basic applications and if needed some other applications like Nagios or Zabbix. My question is for long term support, or patching should I be focusing on deploying with repositories to install applications or compile from source? In the Windows world you can patch and update from Windows Update, but is there problems using 3rd party repositories for future updates? Would one of these locations go off line?

I am currently stationed overseas in Japan, and I am happy to say that I have a 100 Mbit fiber line from my service provider... I am not so happy to say that they force me to use their "CTU", which is basically a Japanese router, which limits me from receiving external connections (such as would be required to host FTP, or administer my home machines via SSH or VNC). I have tried many methods of bypassing this piece of equipment, but so far none have worked (router setup for PPPoE, DHCP, Static IP, so on). I don't think the Japanese would mind me bypassing this device, as it's really there to 'protect' me, but there's such a language barrier that I can't figure out how to tell them what I want to do.
In order to troubleshoot the problem, I would like to setup a spare computer as a hub, dumbly (Is that a word? It is for this circumstance...) passing data from one device to the other, and allowing me to watch what is being passed via Wireshark. I am pretty linux savvy, but I'm completely useless with iptables.
Here is the final product I want:
After connecting eth0 to the fiber modem and eth1 to the CTU, I want the computer to duplicate eth0's distant end MAC to eth1 and vice versa (to simulate the computer not being on the network at all), then I just want the computer to pass any data coming in on eth0 to eth1, and any data coming in on eth1 to eth0. Finally, I need to be able to read the throughput with Wireshark, but I really think that will be very simple if I can get the rest of the setup complete.
One piece of info - there is no dhcp on this link of the network, and I have no way of knowing the MAC addresses of either end before connecting them.
As an added bonus, once I've captured the handshake between the CTU and modem, if someone knows how to retransmit those packets on demand (i.e. to replace the CTU with my computer), I would be quite happy to hear about it.
This is not a regular backup. I only want to backup selective directories so personal files (photographs, documents, sourcecode) will be kept safe in case of a total system meltdown. This'll be 15GB max. Basically the digital variant of a fire resistant safe. I looked into duplicity but that requires me to install gpg keys on the target machine, which I can not do. I rather have a solution that just relies on just a working shell account and diskspace on the target server.
I thought of writing a simple script to do the following:
1. Mount remote server with sshfs
2. Mount encrypted container at remote server (LUKS, TrueCrypt?)
3. Loop over predefined directories on local machine and copy to encrypted container (rdiff-backup?)
Based on these requirements:
- Target server is "dumb": only ssh access + diskspace (i.e. no installing of gpg keys)
- Encrypted container should grow/shrink to fit contents
- Encrypted container should be easily decryptable on any OS if you have the password
- Once data leaves client server it should be encrypted: sysadmin on target server should never be able to see unencrypted data.
I know I screwed up something. I was using Ubuntu 10 minutes ago without a hitch. Then I tried reducing the time I needed to select something in GRUB. So basically, I found this command:

I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns

-rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.

View 14 Replies View RelatedI'm wondering if anyone is having a similar issue to what I'm experiencing. openSuSE 11.2 was very fast on my system. Since installing openSuSE 11.3, I've been experiencing many short term hangs where I'll lose control of the mouse for a few seconds (usually about 2-5) and the system will do nothing. I don't have unusual load during these time periods and I don't really see any spikes during these periods. If I leave a cpu monitor active, I can see a very very light spike one core0 when it happens, but the mouse and keyboard (and seemingly the whole desktop) hang during this spike so I can't see what's causing it, if that's really the culprit.
I am almost suspecting that I'm experiencing an issue with interrupts... since it seems that everything is hanging for a few seconds, then coming back to life. It does seem to happen more often when I'm resizing or minimizing windows... but that's about all I can say as it also seems pretty random.Here's some basic info on my hardware:ASUS M3A78 Pro motherboardAMD Phenom(tm) 9950 Quad-Core ProcessorGeForce GTX 260G15 Keyboard and MX revolution mouse (just in case USB interrupts turn out to be the issue)So, is anyone else experiencing a similar issue?
