remove avahi

bradvan · 07-10-2009, 07:13 AM

I have several RHEL 5.3 servers I am currently setting up. I want to remove the avahi rpms for two reasons. 1, I am using static ips. 2, the group id used by avahi conflicts with the project's software group id. I don't want to have the software with different group ids on different systems. I did an rpm -q -a | grep avahi and see:

Code:

avahi-0.6.16-1.el5
avahi-glib-0.6.16-1.el5
avahi-0.6.16-1.el5
avahi-compat-libdns_sd-0.6.16-1.el5
avahi-glib-0.6.16-1.el5

First, why are two of the packages listed twice?
I then did an rpm -q --whatrequires ... and got that the avahi-glib and avahi-compat-libdns_sd depend on avahi, but did not get any other rpms. I next tried rpm -e --test avahi-compat-libdns_sd and got back a failed dependency: libdns_sd.so.1 is needed by cups.

Second, why didn't cups show up when I queried for whatrequires?

Any advice?

Thanks!

Why not move the project's software group Id instead?

I don't know. Maybe use a query format that provides more than "%{name}%%{version}-%{release}"?

You didn't tell us what you "whatrequired" for.

Because there are existing systems with the project software group ID. I'm not going to change all of them for a piece of software we don't even need.

Thanks for answering one out of three.

Why not just disable avahi from startup...

chkconfig avahi off
chkconfig avahi-daemon off

Do you have 32 and 64 bit versions installed perhaps?

yum list avahi may help.

Why don't you try

yum remove avahi

and have a careful look at what it's saying it will remove before hitting "yes"

Yum won't work because there is no yum server on this network (it is not connected to the Internet). Just disabling the the service is a good idea, but it still doesn't get rid of the group id. I think the 64 bit question hits it on the head why some of the packages were listed twice - once for 32 bit and once for 64 bit. I checked the entire file system to see if the group-id was used anywhere. It wasn't so, I tried to delete it. The system wouldn't let me because it was the primary group for the avhai-autoipd account. I then checked the entire system to see if that userid was used anywhere. It wasn't. So, I delete the user account which also deleted the group id. The package is still installed but disabled, so the dependent packages are happy. Thanks for the suggestions, they helped push me in the right direction!

You don't need a connection to remove packages with yum

Sorry, my lack of knowledge of yum. I'll take a look. The quick answer is that removing the user account solved me problem. In the long run, I like to remove packages that aren't being used. Thanks for the input!
