General :: Unlink Com Port And REDHAT Installation Files?
Jun 1, 2011
I tried to link USB to com port. Mistakenly I managed to link to one USB several ports. How can I unlink them in order to have only one linked? This is how it looks like!
lrwxrwxrwx. 12 May 26 16:26 com03 -> /dev/ttyUSB0
lrwxrwxrwx. 12 May 26 16:17 com10 -> /dev/ttyUSB0
lrwxrwxrwx. 12 May 26 16:22 com2 -> /dev/ttyUSB0
lrwxrwxrwx. 12 May 26 16:26 com3 -> /dev/ttyUSB0
lrwxrwxrwx. 12 May 26 16:27 com4 -> /dev/ttyUSB0
And second question, I have installation files for Redhat(73, 8, 9). Can I install them to Fedora 14? If yes, could you? please, help me with commands?

fprintf(fp,"This data won't be found
"); /* access the data part */

We are currently running Redhat 5.4 64Bit (Build 2.6.18-164.e15) however having issues with tar files that are greater than 2TB in size.
We have been told that upgrading the kernel to support the ext4 file system (supported in version 5.5?) and mounting the current 10TB nas share as an ext 4 file system may solve our over 2TB file size issues. Are their limitations within the ext3 file system that cause issues to files greater than 2TB and if this is the case Do we have to update the kernel (complete rebuild), or can we load a package on the redhat box to support the ext 4 file system Where do we get the upgrade/package. I have logged onto the redhat site and can not find kernel updates but can find the full installation packages. We are not connected directly to the internet and do not have access to the update repository

Im having a frustrating issue with my two machine cluster I setup using Conga. Everything was working great except now when lucci starts mysql the port (3306) is never opened to outside machines. I can do a "ps -ef | grep mysql" and see it running as well as login to mysql on the node it is running on - but an nmap of the machine does not show the 3306 port and I cannot login to mysql remotely and yes I turned off all iptables(iptables,ip6tables) and SElinux is disabled.What am I missing here? If I start mysql on my own (and it is using the same my.cnf as lucci is) it does show the port open and works perfect,t for some reason when lucci starts it, no dice

I really don't know were this kind of action is defined, but I want to replace it by another one.
It should happen either by unlinking that action or by overriding.

I am running RHEL 5.4 Server (32-bit) and have my audit.rules file set up per a template that I am required to use. There is one particular rule that audit is auditing the unlink of files. With this set, my log files are filling up very fast, as there is a particular app that constantly touches/ deletes a couple of files, which the unlink is catching. Here is the audit rule:-a always,exit -F arch=b32 -S unlink -S unlinkat -S rename -S renameat -F auid>=500 -F auid!=4294967295 -k deleteI commented out the "-S unlink" and my logging returns to normal (as expected). For right now, I was wondering if there was a way to set this rule up to exclude these couple of files from what auditd is capturing?

I'm installing RHEL 4.x to a hard disk that already has windows 7 enterprise installed. I would like to dual-boot both the OSes. The hard drive size is about 220 GB (of which windows 7 occupies about 50 GB).Now, is there any free and friendly tool that I can download to partition this drive ?RHEL comes with a text mode (disk druid) to partition and I could not figure out how to resize the existing windows partition. So, I'm assuming that I need to abort the linux install now and proceed to boot from another CD that contains a good partitioning tool and then later resume boot from RHEL install disk.Also, what should my partitions look like ? What size should they be ? The system is a new LENOVO with 4 GB RAM on a i5 core processor.I know that I will need atleast 5 partitions. right ?1) /boot2) /3) /home4) swap5) /var

I'm new to linux and trying to install the driver for Nvidia quardo fx 380 lp in redhat 5.4.From the Nvidia site I got the driver for this card to be NVIDIA-Linux-x86-260.19.12. I did check version of the gcc and kernel built by the gcc version. I also checked the following commands. # cat /proc/version Linux version 2.6.18-194.el5PAE (mockbuild@x86-007.build.bos.redhat.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Fri Oct 29 22:00:21 EDT 2010

I am trying to install Redhat linux 4.0 Enterprise edition in my system. The system starts booting from CD-ROM and starts installation. It prompts for language selection(By default English) and then key board type ( By default US type). After this it is prompting to select the drivers with the following options.
" SELECT DRIVERS", "CHOOSE DRIVERS FROM LOCATION", "BACK". Why it is prompting for drivers?. what type of drivers it is looking for? what is the solution? My system mother board type is Intel 80865.

I have a newly built Redhat 5.5 box. When connecting over VPN and executing either "ls -al" or "df -h", the command prompt hangs without returning any output. Have got same result with TeraTerm and Putty clients. However, other commands run fine. Also,local users are able to run "ls -al" or "df -h" successfully.Storage is local disk. Any idea what could be mis-configured.

VERY new to linux, erm but I have an issue that needs solving!I recently moved to university, where their network blocks sftp port 22, this means that I cannot connect to my FTP server which is running a version of linux.Now I've got this ftp server connected to a seedbox and it was created using the following walk through..Code:I have written this guide for a friend, but I though it would be useful for others as well.
There are several guides floating around, but I found that most always cock up in some way. This one is tried and tested to work on Debian Etch (on an OVH rps, but should apply to most servers).If there is a new stable release of rtorrent/libtorrent then I will update this guide to show you how to update it (without reinstalling the whole server).
At the bottom there are also instructions to install ftp access & some network monitoring software.Basically, I would really like someone to be able to construct the commands on how to change the listen port for sftp connection on linux or add another port to the list that Linux would use so that I could put in through putty.

i am trying to edit sshd_conf files to change the "#Port 22" to "Port 22" from a script.
I have tried this many different ways.
sshs1='s/#Port 22/Port 22/g'
sed $sshs1 /home/l/Desktop/test
the reason i have it as a string in this instance is because $sshs1 gets a variable, but im not working on that right yet. I've tried changing the ' to ` and ". this is what i get:
sed: -e expression #1, char 7: unterminated `s' command
sed: -e expression #1, char 8: extra characters after command
sed: -e expression #1, char 8: extra characters after command
"
sed: -e expression #1, char 7: unterminated `s' command
i know it may have to do with my regex, but i cant seem to find a decent tut.
