Fedora Networking :: Trouble Automating IP Aliases
Jun 18, 2010
My system is F13 (upgraded from F11) with all of the latest patches available. I haven't gone through and combined all of the rpmnew configuration files, but none of them seem to address networking.I'm trying to get subinterfaces (secondary IP addresses) to work in Fedora 13. So far, I have been able to configure them on the command line, but not to get them to persist on booting.My base address for the NIC is: A.B.C.254. It is statically assigned.

I am able to send a mail message to myself from a server without any problem...
But after I have updated /etc/aliases and added the line for all of root's mail to be routed to me....
Added:
root: myemail@company.com
and ran newaliases to implement it....
If I send a mail message to root, it does not get routed to my email...

I am running NIS in an environment that has HP-UX 11.11 64-bit running on a PA-RISC rp3400 server, with Fedora Core 2 32-bit running on intel workstations. All users use the tcsh shell by default in their profiles. If more information is needed please let me know.
Users who log into the domain via a terminal window on the workstations are prompted for the terminal type which is normally dtterm. I want to automate the process so users are not prompted to enter in the above information. My plan is to modify the global-cshrc file on the master NIS server. I had several questions concerning this:
1. Is it better to modify global-cshrc, or should this be done at the individual user directory?
2. What is the correct syntax to use in either case?
3. Will the changes made go into effect upon the next login, or do I need to push out the changes via the make command?

I use Evolution Mail Client everyday on my fedora machine. It has become indispensable somewhat. I am wondering if Evolution can be made to run in the background without the GUI, so it can check mails (IMAP/POP) and post delivery reminders through notify-send. I don't mean evolution-notify-alarm ... I know evolution-notify-alarm runs like that but I think that is limited to calender events and tasks (using data mostly stored locally)
I find that I get notified via notify-send interface only when Evolution GUI is on or minimized. Is there a way to get a real background version of this activity - the GUI can then appear when the Panel Icon is clicked

I am a student at DeVry University, newly introduced to Fedora and Linux in general, and have a project whereby, we have been asked to consider some administrative tasks that we could automate via a script.I was wondering if there were any thoughts or directives from the community on what admin tasks you guys find to be of inestimable use in automating via a Linux script.
I am new to the Linux commands but have done a wee bit of programming before in C++ and others.I have also done basic DOS batch files before.

Not really a linux specific thing I have gooled the heck out of it and tried nslookup -a and a few other options nothing gets me what I need. The question is I have a machine with several aliases in dns. How do I do a nslookup and display all the aliases for a system.
I am trying to see if something it aliased correctly but i cannot list all the names a system is know by.
I am sure its something simple I am missing with a switch.

let me show you my config and tell me if its ok
Its pretty simple:
eth2 -> 192.168.1.0
eth2:0 ->192.168.50.0
eth1 and eth0 are the net interfaces, 1 router each to provide wan failover (not implemented here)
Hosts:
loc1 eth2:192.168.1.0/24
loc50 eth2:192.168.50.0/24
Interfaces
net6 eth0 detect
net7 eth1 detect
- eth2 192.168.1.255,192.168.50.255
Masq
eth0 eth2
eth1 eth2
eth2 eth2
Policy
all all ACCEPT info
Rules
SECTION NEW
REJECT loc50 loc1 all
Zones
fw firewall
net6 ipv4
net7 ipv4
loc1 ipv4
loc50 ipv4
Problems / Doubs:
1) Is the hosts file required?
2) I guess I need doing masq from local to each external, and also from local to local even if they share the same interface, hence the eth2 eth2 in the masq file...
3) So is shorewall well implemented in these scripts to handle aliases?

Upon a fresh install of Fedora 11 (and as a Fedora n00b), I noticed there are several aliases defined for me.
Code:
$ alias
alias l.='ls -d .* --color=auto'
alias ll='ls -l --color=auto'
alias ls='ls --color=auto'
[code]...
files had these aliases. So where are they?

I have a webserver setup, where i need the server to have multiple eht:0 aliases in order to do some SSL-vhosting and other stuff.
The servers eh0 is set up in /etc/network/interfaces (its an Ubuntu)
And i have added the eth aliases with : ifconfig eth0:1 123.231.213.123 up command.
This works great, i can use the additional IP�s for the SSL-vhosts, and all is good.
My problem now is that while the server itself has 1 IP, (and approx 20 IP on alias interfaces) it uses random (i think) IPs when it is to connect to other servers. E.g the main problem is that if a Vhost on the server sends out an email, the server uses a wrong IP in the headers. Thus making it seem like the email is coming from another IP than then on the Vhost it�s currently residing.
Currently, when the server connects to its smarthost in order to deliver emails, It connects from the IP that is bound to the eth0:0 interface, and not the IP bound to eth0 which is desired.
The question now is how do I sort out the IP�s so that all connections the server makes as a client, will use the first (Eth0) IP ?
And all the extra IP-adresses will only be used as "server addresses" not to make client requests.

I have a Windows 7 professional x64 pc that intermittently fails to resolve host aliases. The nameserver is a Fedora 11 system running bind 9.6.2-p2. Its cannonical name is trixter.intranet.org, and it serves several web sites, each with a different host alias: hg.intranet.org, svn.intranet.org, bugzilla.intranet.org, etc.
Occasionally, the Windows pc will be unable to find any of the aliased hosts, even when it can find the canonical name. The aliases will be un-resolvable for a period of several minutes, and then, with no intervention, they can be found again. Trixter can always resolve the aliases to itself.
Even stranger, when I use Cygwin from the problematic Windows 7 PC, it CAN resolve the hosts. I can ping hg.intranet.org from a Cygwin shell, but not from a cmd.exe window. Administrator privileges make no difference.

I am having difficulties to mount my NAS (zyxel nsa210) on startup. After some online research, i stumbled upon the "solution".I was advised to write an entry into the fstab-file and that's what i did.And this actually worked like a charm and i was then able to find NAS in "Places". (Not on my desktop since i disabled it). BUT this works not after booting up...meaning there is nothing like NAS in "Places" and i have to mount it manually by using the "sudo mount -a"-command...there is nothing automatic about this solution...So now my question for everyone capable of answering me: "Where did i go wrong? i have installed smbfs and the folder where the NAS should be mounted in actually exists, so the usual suspects should be ruled out i guess

i have a broadcom BCM4311 802.11b/g WLAN [14e4:4311] (rev 01) wireless adapter on a dell 1501 run by ubuntu 10.10.this particular model and revision is suppose to be absolutely supported by linux and indeed it did work perfectly before the user ran a upgrade from ubuntu 10.10 to 11.04.subsequently i have reinstalled 10.10. as i recall when i installed ubuntu 10.10 the first time i simply ran the System>Admin>Additional Driver installation tool to make the wireless work. i cannot recall if i ran the b43 or the sta driver but i have tried both this time and had no luck.
i am aware that the broadcom adapters are notoriously troublesome and i have tried the two workarounds here URL... as well as their third alternate workaround with no success.

I'm having a tough time trying to wrap my head around the command line and any help would be greatly appreciated. I've downloaded and am trying to install mpg123. I'll tell you what I THINK I'm supposed to do and if someone could correct me where I'm going wrong I would appreciate it.The program is in my downloads folder. it looks unpacked to me because I can see all the separate files but I will assume that I'm wrong. so to unpack it:$ tar -jxvf mpg123-1.9.2.tar.bz
or do i need to unpack it to a certain place like: $ tar -jxvf mpg123-1.9.2.tar.bz ~/username/downloads/if thats the case I tried and it says no file or directory exists. IF I do get it unpacked the install instructions tell me:
1. New installation via GNU autotools
I dont understand because I can see it in the exact file path that it tells me doesnt exist. All I'm trying to do to install some software and its very frustrating because I dont know these simple commands that are the backbone of linux, which I really want to use. I realize that there are a ton of howto's out there but I havent found one that is easy enough to understand for someone who's never typed a command in his life or that isnt so broad and all encompassing that it blows my mind just look at the screen. Please help

Everytime I try to install Adobe Flash, I have problems. I go the RPM route or the YUM route and still have problems. I've even tried yum a 2nd time and it says its already installed, but if I go to a website that requires Flash, it says pluggin missing. On the other hand, if I go and install JAVA it somehow installs the pluggins and everything works from there on. Can someone tell me what I'm missing on the original install ?

I am facing bootup issue in Fedora 14.I troubleshoot the bootup issue i m facing probably because I have done change the name of volumes from disk utiltiy. I read somewhere that it should be done from another place (administration option, the last menu of fedora and there is some volume/disk management..like thing that give rod like blue/red picture of disk=>System-config-lvm) rather then disk utility under system tools. I think that my LVM path is not setup..due to rename of volume..it is mismatched somewhere...that includes path...finally using rescue disk i enter in shell prompt and mounted my system using chroot /mnt/sysimage
then found that my /home is empty, so done some readings and found that using mount /dev/vg_brs/home /home
i am able to get my home fixed that now appeared my user and whole data.
but that is till i m in shell prompt. Don't know where and how to fix/add this line so that boot loader of fedora will take this instead of something other that it is taking and not founding resulting in failure to boot with message (in between lines)

Defining 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

I boot it up using the live cd then try to install it to my hard drive. I want to dual boot Vista and Fedora, so I've created another partition.However I'm having trouble whilst installing. When I get to the stage to select where I want to install it I choose the "Custom" choice. It is then also obvious what partition to choose as one is much smaller. But no matter what options I pick for it, it brings up an error. >_<
I know this is probably a terrible and confusing explanation, but I'm a huge newb to linux and especially fedora.If you want a better explanation please ask and I will try to deliver.

Is anyone else having trouble with waking up from suspend mode? After bringing the computer (Dell Studio 1555) back from suspend mode, GNOME moves very slowly. Cursor is unresponsive for significant amounts of time - any open windows do not respond to selection... Effects don't usually go away until a reboot is performed. This evening, one such restart resulted in a crash, where the shutdown process locked at the attempt to shut down the mouse/pointer module..

I'm trying to install SL6 to a pair of 2TB harddisks in a RAID 1 array. The problem is that when the "Formatting" progress window that says "Creating ext4 filesystem on /dev/mapper/pdc_eahgdeafbgp1" comes up it appears to eventually freeze. It's been like that for 6 hours without the progress bar moving at least. I have another identical system that I booted up using the gparted live cd to see if I could get any more information using that. I first created a 500MB ext4 partition and mkfs.ext4 ran almost instantly. I then tried 5GB and it seemed to take maybe about a second or two and worked fine. I then jumped up to 500GB and it's been running for about 5 hours now. I'm pretty sure that I remember the creation of an ext4 filesystem occuring extremely fast even for very large partitions, but this is the first time I've played with RAID.

I first installed Fedora 15 (full clean install) on a spare laptop I had sitting around and the install went flawlessly. I was able to install it and use it right out the gate. I was then able to install two of my must-have programs, xchat and libreoffice without any problems either.Then I tried the same thing on my primary desktop at work (and since I run an IT department, I already have permission to do this :-)
The problem I'm getting is trying to install anything;the package manager is having trouble contacting the source.The exact error reads: "Software source download failed. Could not contact source 'fedora', so it will be disabled."I have not made anychanges to the firewall on the machine and the machine does have a working internet connection (I am posting from the machine). Any tips or advice on ways to troubleshoot would be great. I'm by no means a linux expert, but I can get around the system fairly well
