No I couldn’t solve the problem, DNS querys are not working I’m planning to format the machine, Until 20 days I can’t touch the machine for that pourpose (web aplication working).
I have Ntop misterious Traffic in the machine I think that it is hijacked, dont know what to do.
One of the configured repositories failed (Unknown),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64
Format the machine!!! in few words for 20 days I can’t move it, now is serving a web applicatión for information with public clients, 20 days and I can disable the machine and setup NethServer 7.5.1804 to fix this strange hijack.
This machine is so important, It Will show the benefits of NethServer to future clients, i Will demmand Crostino plan for support them.
