Re: SOHO images in Linux?
I did it last night.
Go to the GUI/xephem folder. All the files there are read-only. To make them writable: chmod u+w * Then: patch -p0 < (path to patch file.) Several files in the folder are patched. You will be asked about each one. (There may be a switch to avoid this.) Each time, just type again the file name mentioned in the message and hit <ENTER>. When the process finishes, just compile as usual. HTH, Doug. On Mon, 2 Jan 2017 18:09:45 -0500 "Rick Towns rick@...

Hi Serge,

I don't think I know how to use this .patch file. I have the source code for XEphem, and I know how to compile it - but I don't know which file this .patch file gets applied against. Do you know of any good resources that describe this process? I am reading the patch man page and it looks like there's a lot of options. Just curious if you've ever applied this patch? Thank you again! Rick On 01/02/2017 12:02 PM, Serge Montagnac obs.psr@... [xephem] wrote:

SOHO images in Linux?
开云体育Hi everyone, I am running XEphem 3.7.7 in Arch Linux, and I noticed I cannot download the latest SOHO images. It looks like they changed the site to use SSL (port 443) and the program isn't handling the redirection at this point. Has anyone else encountered this and is there a fix? I saw in the help that the URL should be configurable in the file XEphem.SOHOhost, but I do not appear to have such a file on my system? Any ideas would be great. Thank you! Rick

Re: Downloads and Web Updates
What was an HTTP request is now an HTTPS request, which is why you see port 443 referenced, and the prefix changed.? This change happened some time ago, I think it was a couple years.
There are several workarounds, depending on your linux sophistication.? In essence they all work thru a local HTTP server to appear to XEPHEM appropriately, and actually passthru a fetch via HTTPS.? Thus all of the pita HTTPS effort moves into an external program. If you just want images, 'wget' works fine.? If you want to complain, ask SOHO why a fully secure transaction is needed to fetch an image. |

Re: Downloads and Web Updates
Version 3.7.7, fresh download and compile. Fedora 24, x86_64.?MOTIFL = /usr/lib64
Try to download latest SOHO image (same results for any image or size) and?sohowww.nascom.nasa.gov replies (from the log): Rcv: <p>The document has moved <a href="https://:443/data/realtime/eit_284/512/latest.jpg">here</a>.</p> I messed around with sunmenu.c and?XEphem.SOHOhost until the GET matched what sohowww claimed: http: GET https://sohowww.nascom.nasa.gov:443/data/realtime/eit_284/512/latest.jpg HTTP/1.0 User-Agent: xephem/3.7.7 Rcv: HTTP/1.1 302 Found Rcv: Date: Sun, 06 Nov 2016 16:27:36 GMT Rcv: Server: Apache Rcv: Location: https://:443/data/realtime/eit_284/512/latest.jpg Rcv: Content-Length: 233 Rcv: Connection: close Rcv: Content-Type: text/html; charset=iso-8859-1 Rcv: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> Rcv: <html><head> Rcv: <title>302 Found</title> Rcv: </head><body> Rcv: <h1>Found</h1> Rcv: <p>The document has moved <a href="https://:443/data/realtime/eit_284/512/latest.jpg">here</a>.</p> Rcv: </body></html> Error talking to SOHO .. see File->System log Looks like something changed on the sohowww end or there is something platform-specific about httpGET. That href looks suspicious, doesn't it?? XEphem.SOHOhost: ?sohowww.nascom.nasa.gov sends a request that completes.?XEphem.SOHOhost: ?sohowww.nascom.nasa.gov:443 fails before the request can complete, so the :443 had to go into 'fn' or 'get' I hope this information is of use to somebody. |

Re: thanks for using XEphem
Hi,? I have been around XEphem for years and especially appreciated the tie to INDI. It saved money for a local university while providing students an excellent introduction to telescope controls. I hacked a radio source database for use with a 18m dish project. Hacked up some management software to produce .edb files from SQL databases. In short hours of productive entertainment for me! I realize the migration of X-Windows poses a bit of a problem and packages like SOFA are making algorithms available to us that are as precise as the major players. New advances like Astroconda via Ureka and the whole Python environment are rich with opportunities. Not to mention Astropy and ds9.? Now that GAIA is in DR1, we have extremely precise star locations etc.? Wow, what a trip from 1990 to here. So thank you so much for sharing your labor of love with the world for so many years! --Wayne On Mon, Oct 31, 2016 at 9:22 PM, ecdowney@... [xephem] <xephem@...> wrote:

Re: thanks for using XEphem
开云体育Well, I guess - so long and thanks for all the fun. ?I’m not sure I’ll enjoy using many of the other systems out there, most of them look very childish and gameified. ?I liked the clean and professional look of XEphem. ?Like others I’ll continue to use it until it no longer compiles. ?I’m a bit disappointed that making it open source isn’t a consideration, after all the ode is already out there. ?The best thing about XEphem is that it has always simply just worked and rarely needed the constant maintenance and updating of other astronomy packages.Cheers, Mike Chapman

Re: thanks for using XEphem
I'll add my thanks to all the others. I still use XEphem regularly.
If you ever change your mind about open-sourcing it, I'll definitely join and try to contribute. But I understand if you don't want to, and I'm grateful to you for writing this excellent program and maintaining it for so many years. ...Akkana |

Re: thanks for using XEphem
开云体育I have been using XEphem since 1996, when I embraced Linux as my operating system primarily because XEphem was able to run on it. I have been an amateur Astronomer, I used XEphem as a tool to spread science and for my personal enjoyment. Elwood, I am grateful for many years of your effort, passionate work, and dedication. I wish you the best, always. I can not help feeling sad, but I utterly understand your decision.Sincerely, Emilio Ortiz Guinand

Re: thanks for using XEphem
Elwood,
I just wanted to express my gratitude for you writing and distributing the excellent XEphem software. I've been using it regularly for 20+ years and just now realize how much I have come to take it for granted. Anyhow, I expect to continue using it for as long as I can manage to get the sources to compile. I wish you the best in your future endeavours. Regards, Per Erik ---In xephem@..., <ecdowney@...> wrote : Hello everyone, Some of you quickly noticed I recently removed XEphem from my web site. I didn't think there was much interest any longer so I was surprised at the outpouring of everything from anger to grief. It doesn't help that a few people thought they had a right to access XEphem and demanded I put it back up but most of the responses expressed appreciation for past availability and politely wished there might be a way to provide that again. Some of my reasons for pulling it include:
I started XEphem in 1990, based directly on ephem which I started in 1982. I am still surprised that it has enjoyed a wonderful 26 year run. I'm also honored that it is in use at every professional observatory with which I have had contact. I also acknowledge the many contributions over the years that helped the program mature. But the fact remains it is growing less and less viable. Some suggest that I provide XEphem as Open Source. I fully understand how that can lead to perpetual growth, but you must understand XEphem is my "baby" and I just can not release it to the wilds. The ownership of XEphem will follow me to the grave. Writing this note has allowed me to reminisce in my mind all the many events surrounding XEphem over the past several decades. I can understand how those of you who have used it for many years will also miss it. So I have resurrected most of the XEphem web site, including a page for downloading all the source code and data sets. There is no longer a commercial edition, I offer no support and I do not expect to make any future updates but of course no one can foretell the future. Best wishes to all... and thanks for using XEphem. Sincerely, Elwood Downey |
