Server :: Gzip Log Files In Remote Servers?
Jun 7, 2011
I have limited access to several servers (key based auth) but cron facility is not available for me. Those servers getting filled up by large apache logs and I have to login to each node manually and clean them each and every day.
I tried to write a script to run from login box but when i try that it looks like it is looking for logs in the local server (login box).
So current situation is:
How can i modify this so that the script in server1 will look for files in that server and zip them?
Google showed another command called rsh but in my env it is also not avil.

I've tried FXP and rsync, none worked and I can't find much info on how to get them working, just alot of google results with people in the same situation as me!
I want to transfer files from 1 remote server to another remote server... a fairly easy task in which I'm sure there's an easy solution, I just can't find it.

so this is really the result of another problem. There seems to be an issue with CPU spiking to 99% forever (until reboot) if I run apt-get or synaptic or update manager while an external USB drive is plugged in. Note, other USB peripherals are no problem, just an external HD.
So my work around was to eject the drive when doing apt-get or other installation work, then reattaching it to remount. Now, on to the present problem. I'm using the basic backup script (the rotating one) found in the Ubuntu Server manual. It uses tar and gzip to store a compressed version of the desired directories on my external USB. (which sits in a fire proof safe - this is for a business)
However, it seems tar and gzip which run nightly 6 days a week via cron as root, don't ever want to die, and they don't release the drive. I have to reboot the system (I can't logoff) to release the drive, unplug it, the I can do update/install work.
Of course, if apt etc. would work fine without conflicts with the external device, I'd not care about the tar/gzip problem other than it generally isn't a proper way for them to function and it chews up some CPU cycles. (they run about 0.6 and 1.7 percent respectively) I also can't kill them via kill or killall. They seem undead.

I have installed debian on my dell latitude d630 laptop and am currently making a derivative for others to use. however I can't get the wireless to work. I downloaded it from the broadcom site but it comes as a gzip file instead of a deb file. if I extract the gzip file I don't get any installable (deb) files. I need the wireless to work because now a bridged network from my windows laptop isn't working.

I have a script which periodically backs up a directory using the command "tar -czvf [name] [directory]" but my problem is that the script has recently been putting a lot of stress on the server (Minecraft SMP) and tends to lag players as it backs up, which recently has been taking nearly 5 minutes.So I need to know if there's a way to control the GZip compression rate at the same time that it archives and backs up the files?I understand that I can first tar the files and then GZip them separately with a different compression rate afterwards, but this would not work because it names the files with the current server time, which sometimes changes in between commands.

I'm trying to dump a mysql database on a small web server without killing performance. I tried using the nice command to give the mysqldump and gzip a low priority, but gzip is still taking up 100% CPU. Pages on the web server are loading incredibly slow. Here's my command:
Code:
nice -n 19 mysqldump -u USER -pPASSWORD DATABASE | nice -n 19 gzip -9 > OUTFILE.sql.gz How do I get gzip to run without taking up 100% CPU? I've attached a screenshot of top about 8 seconds into the dump.

I'd like to configure vsftpd server in a way to allow remote user (local) too see and edit configuration files in their ftp directory starting from dot (like .htaccess, for example). With default configuration + "local_allowed = yes" it does not appear to be possible:user can successfully upload .file but could neither see if it is in directory nor download it.

I support a small business which runs a headless Ubuntu Server (10.04 32bit) as a file server which is accessed by Windows machines.Although the company has it's own back-up procedure they have decided to back-up some (none sensitive) files online. The have chosen FileFactory (http://www.filefactory.com/) as the host for this. FileFactory allows files to be uploaded to their server by FTP however I do not know how to set this up on the server.
The idea, if it is possible, is to connect to FileFactory through FTP and then synchronise the data using an Rsync command.I normally access the server through Webmin and it has vsFTP installed. I can access the company's server by FTP from inside and outside of the network so I know that vsFTP is working for incomming connections however I cannot work out how to configure it to connect to the FileFactory server.

Allright, I made a simple script that tarballs my SQL databases weekly and saves them to a backup harddrive.If possible, I would like to have the backups uploaded to a remote server for storage. But, I must have the script delete the previous upload for size contraints.I can only use rsync, scp or sftp. Haven't used any of them really before... Here's my basic tarball-backup script:
Code:
#/bin/sh
# Dates the new tarballs of current builds.
DATE=`date +%m_%d_%Y`

Does anyone know the best and simplest way to do this? I'd like the share to be mounted over the tunnel on boot with as little scripting as possible and be as secure as possible without exposing more than one port to the outside. I will be trying this method: [URL]... once the tunnel is established and 'always on' NFS would take care of the file system mount obviously. Lots of the information I have been reading is not up to date it seems. Does anyone have any experience with this?

I have a computer set up running an apache httpd server with the basic LAMP functionality. I logged into the server today and noticed numerous attempts by a remote IP to access various files on my server.
Code:
[Fri Nov 26 07:37:56 2010] [error] [client 72.167.161.46] File does not exist: /var/www/html/phpMyAdmin-2.8.1-rc1
[Fri Nov 26 07:37:56 2010] [error] [client 72.167.161.46] File does not exist: /var/www/html/phpMyAdmin-2.8.1
[Fri Nov 26 07:37:57 2010] [error] [client 72.167.161.46] File does not exist: /var/www/html/phpMyAdmin-2.8.2
[Fri Nov 26 07:37:57 2010] [error] [client 72.167.161.46] File does not exist: /var/www/html/sqlmanager
[Code]...
There are many many more lines similar to this but its obvious that a remote host was attempting to run my phpmyadmin page and gain access. My question is that since I'm a novice at running httpd what sort of things should I be looking out for in regards to security and configuration to prevent any attacks or is this common and should just be ignored? I do run phpMyAdmin on the server and have configured MySQL to not have blank passwords or user accounts. The database had no new changes to it so I doubt they actually accessed it.

I have a compressed backup that I want to crypt and upload to a remote server through ssh once in a while. The problem is with the size, more than 4 GB. If the connection drops how does scp know to resume? This should be an automated process.

I am running a local webserver mainly for development. I have everything set up. The issue I currently have is that I cannot shut down the machine from the command line. I can issue the command but the machine remains on. I also cannot get to the desktop via VNC.The reason for this, is that there is no monitor attached so Ubuntu says that it is trying to run in Low Graphics Mode. I found this out as I plugged the monitor in to my server.So question is, how do I get around this? How can I set up Ubuntu to get past this, or do I need to install Ubuntu Server?

I am looking for a client/server application that can allow me to have remote GUI access (eg: VNC) but with the ability to use sound.
I see that TeamViewer has a linux application out now but for my company, it would compromise security protocol because it reaches out to the TeamViewer servers to do any work.
Basically, we have applications that require a GUI and we need to hear sounds from them if they throw an alert (the app is a monitoring tool).
We are running a VNC server on it currently and when our monitoring machine was on Windows, TightVNC was able to get the sound...that is not the case with any Linux client so I am wondering if there is actually one that exists.

I already have an ubuntu backup server in my location and need this one server to be backed up remotely in another state. this other location is a helpdesk so there's a danger that they can gain access to confidential data. I'll be setting up this new server as an ftp server but need to set the ftp folder to only allow access to the backup server and me. Because its remote on the helpdesk side, they'll need some access to the file system but need to be completely blocked off from the ftp folder where all the data is at. How can I make sure I can keep them away from my data and still be able to retrieve or copy files over without permission issues between both servers?

I discovered in running a script on a remote server. Take this little demonstration script:
[Code]...
This runs as expected (it does nothing) on both my local desktop and the remote server. However if I log in via ssh to the remote server and run this script everything on the server freezes. I do mean everything ftp/ssh/nfs/login-requests/... even if I go and physically plug in monitor and keyboard there is no response. It basically needs a full restart to clear. I have repeated this several times. Now something is clearly wrong here but does anyone know what. I didn't think a non-admin user should be able to actually lock up system processes.

I have a Godaddy UCC (Multiple domain) certificate for the following domains:
example.com
upload1-example.com
upload2-example.com
The rsa was generated from example.com server using example.com as CN Common name.
GoDaddy's website adds the extra names to a CSR you provide, does the checks and grants the cert.
My problem is that whilst the certificate works fine on the server example.com (from which the csr was created), it comes up with two errors when restarting apache on remote servers.
1>> Certificate common name does not match server name
2>> SSL Library error - check private key:key missmatch.
I donn't understand how these keys could ever work as no reference to the private keys of the remote servers is ever used in creating the UCC certificate.

I have a problem while copying files from a remote computer to my local one using the scp command. I am sure that I am using it correctly, please check it below:
---
blah@blah.com:~/g4work> scp blah2@blah2.com:IndirectMethod_Spher...s/H_1.mac.root .
---
What I get in return (instead of the statement saying 100% of file copied) is:
---
On this machine the G4SYSTEM=Linux-g++
---
The interesting point is that the above returned statement is one of the Environment variables set on both the machines that are necessary to work with a toolkit called Geant4. Here is what I get when I type 'printenv | grep G4' just to show you (note the statement in bold):
---

The other thing that I would like to mention is that these Geant4 Env. Variables are loaded each time a new (bash) shell is started as a result of the bash login script.

I am playing around with the idea of being able to use a cloud or instance based service to install Ubuntu 9.10 Server. This will enable me to have remote access via SSH command line.So far, I've installed Ubuntu 9.10 Server + Ubuntu Desktop to a virtual machine. I can access this via SSH and locally via the desktop. However, in the real environment the only access I am going to have initially is via SSH.
I would like to be able to connect using Windows Remote Desktop or VNC (whichever is easier and most importantly - most secure) to the machine.. even though the desktop is on there, I need to somehow configure the remote access all from the command line.I've had a read of various forums and have been trawling support forums for days but can't find a working solution for 9.10 Server or that fits my situation above where I will not have any physical access to the desktop or machine to configure remote desktop. It all has to be done via SSH/command line.

I was trying to install PEAR on a remote Ubuntu server using putty. I ran an apt-get install php-pear command and everything went smoothly, but now i cannot access the website as it says 'can't establish a connection to the server' and in firebug, it shows the status 'aborted'. I even tried adding the pear path in php.ini file and restarting the apache server but no luck.

I have a fast computer in my office and I want the person using the slow computer in the same office to boot up and see the login window (gdm) and log-in from there into the fast computer and be able to use their session on the fast computer the same time I am locally logged in to the fast computer as a different user and session.Is this best done through XDMCP?

I have an ubuntu fileserver and an ubuntu laptop both running 10.10.For some reason I can't connect to the server (file or remote terminal) from the laptop, even though I can access ssh through terminal on my mac and have been able to mount the filesystem on another computer running the ubuntu liveCD. I just get the error 'no route to host'.I've tried turning off the firewall on the laptop and re-installing ssh on both computers, but I don't have a clue what to do next!
