What is the least painful way to temporarily prevent uploads to an FTP server by certain accounts? they all only upload directly to their home directory setup in /etc/password
View 1 RepliesI just noticed that even if I remove read and write permission for my files, another user can access those files if they use 'sudo'. The ls -l for the folder containing my file (let's call is myfile') looks like this.
"
Code:
-rw------- 1 username groupname 43 2010-03-09 20:23 myfile
"
I logged into another account I have made for myself (which had admin privileges) and then did
Code:
sudo nano /username/home/myfile
and ... the file was opened and I was able to read it. So what's the point of having user permissions if someone can bypass them by using sudo?
i was fiddling with some new commands i learned and typed something weird. Then bash broke on me for a while. here's the command i typed while in /bin bash > lessi believe i was in "sudo su" as the moment. i want to understand this because when I typed it bash didntork. i tried to type "ls" after and it didnt result in anything.but thats not all it didnt receive any commands.Was this a crash? and why/how did it fix itself after i logged off.

# service iptables save
# service iptables stop
# chkconfig iptables off
# iptables -F
# iptables -X
# iptables -t nat -F
# iptables -t nat -X
# iptables -t mangle -F
# iptables -t mangle -X
# iptables -P INPUT ACCEPT
# iptables -P OUTPUT ACCEPT
Its seems to work temporarily and then the firewall gets enabled again by itself even without restarting.
I wanted to set ACL for a directory. For that it is important that the device should be mounted as acl on that directory.
But I do not want to add the acl mount in /etc/fstab. So I am tempoararily mounting the device to some temporary directory as acl and setting ACL and then unmounting it. Then, I'm mounting it to the original directory.
The code is below:
tmp="/tmp1/backup"
orig="/mnt1/backup"
dev="/dev/sda2"
mkdir -p $tmp
[Code]....
The group is being changed, but ACL is not set for the directory.
I am continuously getting fork: resources temporarily unavailable even when I am typing ls command.

The following methods are not allowed:Turning off the router. That would lead to a lot of angry young individuals. This method must be particular to my workstation.Use root privileges (coz I do not have them).
Yank the ethernet cable from the system.Why: Sometimes the internet proves to be a distraction.I am using the following system: Fedora release 11 (Leonidas), linux kernel 2.6.30 and GNOME 2.26.3

I would like to know if it is possible (and, if so, how I would go about doing so) to temporarily limit my Internet connection on a Linux box.
I am developing some new features for one of my Web sites, and I want to see how it performs when using a slower Internet connection. Although it's great for most aspects of my job to have a lightning-fast connection (around 25000-30000 kbps download and 20000-25000 kbps upload speeds), it really makes it difficult to know even what average users might experience when using some of the aspects of our Web site.
I have Linux Mint installed in VirtualBox on my computer, and I'd like to find some way to potentially temporarily "trick" that installation into using a much slower connection to the Internet for testing purposes.
I'm using sendmail and I'm trying to set up some forwarding accounts. It seems simple enough but all the results I've gotten on Google so far are pretty unhelpful. Isn't there a straightforward tutorial somewhere?
View 4 Replies View RelatedI have a server and I have a few computers connected to it via a Airport Extreme. Using network cable. So when Im uploading,(ftp) IE using a lot of the network "space" the other computers on the network gets kicked out. So what is going on? My Airport Extreme is doing fine, but my other clients just get kicked out. If I pause the upload, everything is okay again. The whole network is 1 gigabit, clients, everything.

View 1 Replies View RelatedI will expain my setup :
SERVER 1 - SHARED ACCOUNTS
SERVER 2 - RESELLER ACCOUNTS
On server 2, all of a sudden my resellers are complaining that the accounts they create are not working, so I checked out.. and I realised that the accounts all have 'Unknown' as the IP.
So, steps I took so far...
1. Rebuilt Apache
2. Restarted the server
After each of these steps I have created new accounts, and still I have this error.
Sometimes I notice that there is high upload speeds for 10 minutes or so. At the time of the screenshot I was sitting in a public wireless place, only chromium was open and I don't see any reason why there should be sustained upload speeds.Is there a GUI or CLI so I can find out which process uses the internet?

View 4 Replies View RelatedI am working on a PHP enabled webpage that will allow a user to select multiple files and directories to upload from a local machine to an ftp server. I am comfortable with uploading the files from the machine to the server. The problem is making it easy to select all the desired files. What I would like to do is create an expandable file tree that lists all the directories and files on the local filesystem. From there, the user should be able to select directories and files using checkboxes. Upon clicking submit, all of the selected files should be fed into an array of files that can be sequentially uploaded to the ftp server.
View 1 Replies View RelatedI am looking at creating two user accounts for "contract system admins"..These guys will be performing sys admin duties for a sever -- however, I am still concerned about security of data. For example, the server contains password information for our database, etc.Besides making them sign an NDA, etc. what other security mechanisms could I put in place to ensure that they don't just go buck wild. For example, when someone makes a sudo command, is this logged?
what are some recommendations for general security practices?

So found one issue: When torrent upload speed reaches peak speed (160-200 Kbytes/s) huge read slowdown happens. Server becomes almost unreachable... It allows to connect via putty but it takes a lot of time.
Tested top stats during those lags (Deluge, Transmission) - 10-15% CPU usage.
So I think the problem is in LVM and not in CPU.
How is it possible to find weak place in system to avoid those lags... Cause if torrent is seeding it's impossible to watch movies through network form that server.
I am uploading the incremental backups using duply/duplicity using the sftp-module. As the initial upload is pretty big and runs several days (more than 50GB over a 1Mbps-line) I am confronted with the problem that other users in the network experience slowdowns when I upload.
I would like to run a script every n minutes which pings a host in the internet (second hop of the traceroute for example). If the response time is less than a value (150ms), the script throttles the upload for one specific host and protocol. Traffic to the local net (Samba mainly) should be unaffected. I cannot use the QoS of the firewall/router. Also I would like the penalty to be removed if the ping is quicker (loess than 70ms for example) I looked at trickle, and some other out-of-the-box shaping tools but they do not give me the possibility to change the rate while the upload is running.
I would now write a script in perl which uses [URL]some wrapper for iptables combined with some ping module [URL] Also I was trying to get the proof of concept before I start coding: (I haven't verified if this works yet)

My Linux laptop has recently been hanging for no apparent reason, and so I have been using a Mac OS X laptop in the meantime. I just installed Thunderbird and wanted to copy all my preferences and account settings to the new laptop. All email accounts are IMAP based.Can I simply copy the data, or does Thunderbird for OS X store data in a different format from OS X? What about if I wanted to copy the preferences to Thunderbird under Windows? Finally, what files do I copy? I haven't powered up the Linux laptop yet but I'm guessing there's a ~/.thunderbird/ directory, can I just copy this to the Mac?
View 1 Replies View RelatedI have been using a cron job to duplicate a folder into another users account every day and someone suggested using symbolic links instead although I cannot get them to work. In summary user GAMER generates log files that they want to access via HTTP, however I only have a web-server in the user account SERVER, in the past I would copy the logs folder from GAMERS account into SERVER/public_html/. and then chmod the files so the server could access them. Trying to use symbolic links I set up a link from root (as only root can access both accounts) I used: ln -s /home/GAMER/game/logs/ /home/SERVER/public_html/logs
However it seems that only root can use this link, I tried chmoding the link, all the files in the gamers /game/logs/*, /game/logs itself to 777 as well as changing chown and chgrp to server the files still cannot be read. When viewed from servers account my shell shows the link and where it is to hi-lighted in black with red text. /home/GAMER/game/ (chmod & chgrp) drwxrwxrwx 3 SERVER SERVER 4096 2011-01-07 15:46 logs

I am trying to figure out a way to pull the user information from local users on a Linux server. I have approximately 40 servers running SUSE and Ubuntu that are using Microsoft Active Directory in order to authenticate. Our internal auditing group has made us disable root ssh ability, I was doing this with clusterssh, but I can login as me then su on the server to conduct root, admin, work. This is an ongoing request to get the local users and it is a painfully slow process since I have to login to each server to get the /etc/passwd file. Is there another way to get the local user information? They are now asking about seeing the last logon date or if the account is disabled, any thoughts there as well?Most of our auditors think Windows and I am trying to make my life easier but not sure what options I have. I need to get local accounts and if they are active or disabled plus last logon date. I'm sure there will be more but if I can get the basics adding more shouldn't be too difficult but I guess I'll cross that bride when I get there.
