From what I have deducted so far is that sshd in F36 and F37 generates new xauth token and replaces the old one every time new connection is opened. I can fix the problem by running xauth list after the first connection and then xauth add with the data from xauth list to restore the original authentication token every time new connection is created. One might make a hack with /etc/ssh/sshrc or .ssh/rc to muck with the tokens, but I am not sure it's a good fix on the long run. Would be nice to know what changed from F35, but I don't unfortunately have any installed anymore. -vpk ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue

Hello,
Can somebody help me?
This short piece of code fails.
It seems to be due to the gsl library!
Thank for your help.
#include gsl/gsl_multifit_nlin.h
int main () {
const gsl_multifit_fsolver_type *T_ ;
gsl_multifit_fsolver *s_ = gsl_multifit_fsolver_alloc (T_, 10, 1);
}
You haven't initialized T_, so when you call
gsl_multifit_fsolver_alloc, it fails because it doesn't know what
solver type to allocate for.
So, try initializing it, eg.
const gsl_multifit_fsolver_type *T_ = gsl_multifit_fdfsolver_lmsder;
warning: initialization from incompatible pointer type [enabled by default]
const gsl_multifit_fsolver_type *T_ = gsl_multifit_fdfsolver_lmsder ;
fsolver and fdfsolver are not compatible!
I did not find a way to initiate this pointer.
Try this code:
#include gsl/gsl_multifit_nlin.h
int main () {
const gsl_multifit_fdfsolver_type * T = gsl_multifit_fdfsolver_lmder;
gsl_multifit_fdfsolver * s = gsl_multifit_fdfsolver_alloc (T, 100, 3);
}
from: http://manpagez.com/info/gsl-ref/gsl-ref-1.12/gsl-ref_507.php
Atleast I got it to compile and run without segfaults.

Including his mobile devices. And, of course, he has RAID to minimize loss of data. With the NAS devices you can get other set of problems. I have for example been rescuing data from NAS which had sparc processor and it had formatted ext3 in a way that you couldn't read it in Intel processor machines without doing extra things and using drivers in alpha state (and which development had stopped and you needed to compile yourself) So if going to nas route should check that you can actually get something out of the drives in case of box going bad. Or actually take backups instead of always planning to do them. If you don't mind others (Like your more or less friendly spy agencies) to read the code in git repository one way to share the stuff with multiple machine is actually keeping the repo in Dropbox or something similar which actually copies the data to multiple places. -vpk -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

You could look at the source to find an answer. Perhaps it's great --- but I doubt it. Seriously? Looking the source? Except developers who will dig in the source code? None user will dig the source code, they just will leave the distribution or worse the all Linux area if they can't solve their problem. I think, if the user can't find solution, (s)he will accept it, but if there will be too many, they just escape. Escape where, OSX has similar thing which seems to be even less documented (only my impression might be wrong). Solaris has moved something similar. AIX has never been truly SYSV and needs special hardware. BSD's will work but have their own set of fun and are geared in my experience more to people who like to mess with the code. And some of them are planning to move to the thing used in OSX (or in it's opensource upstream). Windows also has extensive ways to manage how processes will start in startup etc. Maybe the thing is that world has moved forward and there is needs which traditional sysv init doesn't answer anymore. And any way you feel about systemd something similar would have come anyway and it actually did and people weren't happy so in came systemd instead. If there is real problems with systemd I am sure someone will sooner or later fork it and do different version. That's the choice in free/open software it's freedom of making your own if the current solution doesn't work for you. Nothing of this freedom is taken away. It's just that those people who actually do work for getting the distributions out have seen that systemd is only maintained solution at the moment. I think it's somehow telling that no one else is even trying to make better solution to the problems. It doesn't mean there isn't ways to improve systemd (or make a replacement), it just means no one is willing to do it. -vpk -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

Does anybody know of a good step-by-step guide for this (preferably free and online :-) )? As for the answer to your initial inquiry i would highly recommend ROCKS Clusters that is based on CENTOS. it will automatically install and manage your nodes from a single point (the FrontEnd server)(with NFS shared home). I have tried ROCKS before (granted it was maybe 6 years ago) and it seems good if you have very lage number of nodes. If not then I would recommend setting the things yourself. Most programs run in scientific clusters use MPI for shared communication so you will just need MPI setup I would not waste time job management and such as long as there is only one person running on the cluster. Setting up maybe 10 to 20 machines with kickstart using fedora with openmpi, ssh-keys for easy access to nodes and nfs sharing form frontend shouldn't be that big job. You will take same amount time learning ROCKS and it will have lots of features you don't need. Also if you don't use the machines all the time and don't have the hardware yet it might be beneficial to use AWS nodes to do the calculations. In big HPC setups the real cost of the cluster usually comes from electricity consumption and cooling so you should factor these costs in when deciding what to do. -vpk -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

One thing I learned from this is that one can't trust even RH to actually test the core features of the releases in automated way.
