1). What is the console command to scan all of Fedora, not just a specific directory, but the entire computer?
2). Even tho I have consulted the CLAM AV site on how to update to the latest virus signature database, I don't either understand what they are telling me to do, or I am not "getting" how to do it.
I'm running Fedora 12, and I need to disable the firewall from within a shell script, which rules out system-config-firewall. I tried the following:
Code:
service iptables stop
service ip6tables stop
chkconfig iptables off
chkconfig ip6tables off
but that didn't do it.
I have recently installed Fedora 14 on a new computer we presented as a gift to my sister-in-law. She is new to Linux. Although I've used Fedora since Core 1, I'm no expert on security issues, and this baffles me. She's doesn't know how to change the root password, so why doesn't it work any more? She discovered the problem when attempting a yum update from a terminal.(1) How could the root password have gotten changed? How likely is it that someone got onto her system through ssh, made a lucky guess on her root password, and then changed it? Are there robots that do this?
(2) The firewall is enabled. I have it set up as follows: (a) under "Trusted Services," only ssh is checked (I need to be able to get in remotely this way); (b) under "Trusted Interfaces," I have eth0 checked (I need to be able to use VNConto her desktop).Question: Are these settings giving ample protection? What settings would be recommended to protect her system while at the same time allowing me to access it through ssh and VNC?
How can i install the ls command again?
View 6 Replies View RelatedI'm migrating my file server from Fedora 9 to Fedora 11 (clean install), and I'm having a horrendous time trying to get key based SSH logins working. I've set it up before, and I can't figure out why it won't work now. I copied my public key into ~/.ssh/authorized_keys2 and set the folder permissions for 700 and the file permissions for 600. Then I restarted sshd. Now unless I remember wrong I thought that's all you have to do. It didn't work. So I rebooted just for good measure. Still didn't work. So I made sure that my client was still sane. I can log into my OpenBSD machine just fine. I compared the sshd_config from OpenBSD to the Fedora one, and the options seem pretty close.
At that point I had nothing to lose and just started messing with the Fedora sshd_config. I also noticed in the config that the commented AuthorizedKeys file had dropped the 2 off the end, so I tried changing that as well. Still nothing. Password based logins work, but I really don't want to go that route. Now I can only think of two possibilities. One, some sshd_config setting is wrong and I don't know what it is. Two, there's some package that's required for key based logins that I accidentally unchecked during the install process. That's about all I can come up with. Here's my sshd_config, I tried to just set everything back to default.
Code:
#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
# Disable legacy (protocol version 1) support in the server for new
# installations. In future the default will change to require explicit
# activation of protocol 1
Protocol 2 .....
I am trying to email some log files from my RHEL 5.3 server to my Outlook corporate account and nothing happens. Here is the command I use:[root@server1]# mailx -s "server info" my_id@my_corporate_domain < server_infoThe file server_info does exist and is a small log file. I checked for sendmail and seems to be running OK as follows:
[root@server1]# ps -ef | grep -i mail
root 13954 1 0 2009 ? 00:00:00 sendmail: accepting connections
smmsp 13962 1 0 2009 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
I'm not at all familiar with mail clients or mail system in Linux. Is there anything missing? I don't have to use mailx, I could use an alternative. Just please let me know how to sent a simple mail from this server to my corporate account using any tools possible (and maybe how to set it up)
I tried using the jobs command in bash in F14 but nothing happens.
Code:
[root@Fedora ~]# jobs -l
[root@Fedora ~]#
Code:
[root@Fedora ~]# which jobs
[Code].....
If jobspec is given, output is restricted to information about that job. The return status is 0 unless an invalid option is encountered or an invalid jobspec is supplied.
If the -x option is supplied, jobs replaces any jobspec found in command or args with the corresponding process group ID, and executes command passing it args, returning its exit status.
Is the jobs command dropped for the ps command instead ?
I am trying to execute 3 commands stacked together on a remote server. The purpose of the commands are to get the oldest path name, then the filename of the oldest file in that path, and then the date/time of that file.
The command I am running is: stat -c %y $( find -L $( find -L /home/data -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1 ) | grep txt | sort -f | head -1 ) This command works fine if I execute it on the command line of the server. However, when I try to use it in a bash script and execute it from one server on the other server using ssh, the command does not work.
Example:
oldest_file=`ssh -l root $IP "stat -c %y $( find -L $( find -L /home/data -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1 ) | grep txt | sort -f | head -1 )"`
I don't know why the command will execute if I run it straight on the server but not through ssh. I broke it down to just the 2 Find commands and saw with verbose turned on that the path from the first (innermost) Find is not being passed to the second Find so it is not returning a filename which inevitably makes the Stat command fail.
Also, if there is an easier way to do what I am trying to accomplish without stacking these 3 commands like this, then I welcome those suggestions as well since I am a Linux newbie.
I want to print Landscape and I would normally use Code: lp -ddestination -olandscape However this isn't working, it could be another problem (I am passing to a windows print spooler) but I would like to know if I have got the command right.
View 1 Replies View RelatedDefining tcsh aliases through a .aliases file has worked perfectly for me for years and years using cygwin and older versions of mandriva. I am encountering very annoying and mysterious problems when attempting to do the same thing with a .aliases file in a fedora 64-bit VM. Strangely, if I define aliases in the file, they won't work, but if I do so on the command line, then they will.
Here's a simple example: Suppose I define an alias for "ls" in the file:
alias ls '/bin/ls'
Then source the file. This happens:
me: ls : Command not found.
me: alias ls
/bin/ls
me: /bin/ls
file1 file2 file3 etc.
me: unalias ls
me: ls
file1 file2 file3 etc.
me: alias ls '/bin/ls'
me: ls
file1 file2 file3 etc.
A second example: if I place either of these lines in my .aliases file:
alias d '/bin/ls -alF !:1'
alias d '/bin/ls -alF !*'and source the alias file, this happens:/ me: d
Bad ! arg selector. However, if I define the alias on the command line:
/ me: alias d '/bin/ls -alF !*'then the alias behaves correctly:/ me: dtotal 376

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.
