Wireshark not running on CentOS?

deostroll · 08-17-2009, 10:00 AM

I've installed wireshark using yum on centos. After the install when I typed 'wireshark' the shell couldn't recognise the command?

The wireshark-gnome package is also available. Could you post the results of ' yum repolist '?

Here is the repolist:

If you compare the number of packages in our base repos you can seen a huge discrepancy. You can try a " yum clean all " and then recheck your " yum repolist". If they are still showing the same post your /etc/yum.repos.d/CentOS-Base.repo file. It MAY be that you are locked onto a goofy mirror sight(rare but it happens occasionally).

I THINK the mirror you are using:

mirrors.hns.net.in

is probably bad. Please post the contents of your /etc/yum.repos.d/CentOS-Base.repo file.

Ok, the repo file looks fine(I thought maybe somebody hard coded in that specific repo).

There are two ways(main) to get around using that repo(only use one):

1st:

yum remove yum-fastestmirror
yum clean all (yep again)
yum repolist

Hopefully the list will change.

2nd:

Edit your repo file moving the # in front of the baseurl line to the front of the mirrorlist line (just on the [base] section). One or the other of these two lines MUST contain the #(makes it a comment). Again followed by a yum clean all and another yum repolist.

deostroll · 08-18-2009, 03:21 AM

yum remove yum-fastestmirror has completely removed yum. I can't run yum in the shell again! How do I revert it?

lazlow · 08-18-2009, 04:23 AM

ANY time you are using yum make sure you read what it is telling you. It would have told you that it was removing yum and asked you to confirm.

Go here(assuming 64bit):

http://mirror.centos.org/centos/5/os/x86_64/CentOS/

You should be able to double click on the yum rpm and install it that way. IF not it may have removed more (dependencies), in that case you will have to save the rpms and then install them via rpm(see man rpm). Because rpm will not handle dependencies for you, you go through multiple install/download cycles.

deostroll · 08-18-2009, 04:45 AM

Q: How do I know the architecture of my mach?
Ps: I believe it is 32-bit
Is this the right one:
http://mirror.centos.org/centos/5/os...tos.noarch.rpm

lazlow · 08-18-2009, 04:55 AM

You can use uname -a. For a 64 bit kernel it will look like:

Quote:

[fred@localhost ~]$ uname -a
Linux localhost.localdomain 2.6.18-128.4.1.el5 #1 SMP Tue Aug 4 20:19:25 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

with the x86_64 being the important part. For 32 bit it will be i686 or similiar.

In this particular case either address will work as the rpm is a noarch a rpm. Assuming your kernel is 32bit your address would be better(for most rpms, ie non noarch rpms).

deostroll · 08-18-2009, 05:20 AM

Man, I sort of had to figure out the right way to use rpm. Anyway I got it fixed I think.

Code:

[root@chat rpms]# ls
yum-3.2.19-18.el5.centos.noarch.rpm
yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm
[root@chat rpms]# rpm -i yum-3.2.19-18.el5.centos.noarch.rpm
error: Failed dependencies:
        yum-fastestmirror is needed by yum-3.2.19-18.el5.centos.noarch

Tried installing the wireshark-gnome package. Now wireshark works. I can simply type it in the shell. However, I still wonder why it never appeared in the shell earlier; it was installed, right?

lazlow · 08-18-2009, 10:42 AM

I suspect that something on the initial install went amiss(it happens). Usually problems like this show up when third party repos are mixed, which is why I initially asked for your repolist. Obviously that was not the problem in your case. When you installed gnome-wireshark did you happen to notice if you were drawing off a different base repo address( other than mirrors.hns.net.in)? IF it was from a different site, it would be an indication that it has an issue (basically hung). If it was from that site I would say that you just had bad luck.

I would like to commend you on your skills. A lot of new users would not have gotten through this experience without doing a fresh install. Learning to install using rpm after the loss of yum is a HUGE step. While I would advise against using rpm for the most part(in favor of yum), it is an extremely valuable tool to have at your disposal(as you now know). This experience also has demonstrated to you how closely you have to read the information that the system is providing you. Essentially if you tell the system to shoot you in the foot, it will confirm that is what you really want to do and then do what you told it to. This is a double edged sword. You have complete control over the system, which means by definition that you also have the control to destroy the system. Congratulations.
