DNS and svn executable

[Anton Burkun <an...@gmail.com>]

Hi All!

How svn executable use system to resolve host IP?

I running next line with EXEC from script

svn checkout --username=*** --password=*** 
http://opensvn.csie.org/lecom_web_site /home/lecom/public_html

I get error:
svn: PROPFIND request failed on '/lecom_web_site'
svn: PROPFIND of '/lecom_web_site': Could not resolve hostname 
`opensvn.csie.org': Host not found (http://opensvn.csie.org)


But when:

svn checkout --username=*** --password=*** 
http://140.112.172.10/lecom_web_site /home/lecom/public_html

All ok.

WHY?


Anton.

Ping is not DNS.  Your server can respond to a ping without needing to  
do a successful DNS lookup.

What happens if, on the server where svn is failing, you type in "dig  
+short opensvn.csie.org"?  If DNS on that server is working, then  
you'll get the IP address back.  If you don't get the address, or see  
some sort of error, then you've got a DNS problem.

I suppose it's theoretically possible that when you compiled svn it  
failed to link in the correct libraries to be able to successfully  
call gethostbyname()... but that seems pretty unlikely.

By any chance did you compile this on one system and then move it to  
another one?  If so, check to make sure that all the relevant  
libraries are present, and at the same version.

But my hosting admin says what no problems with DNS resolution. Pinging 
my host goes.
And I try to move repository to another server - problem is still present.

svn just uses the system resolver.  So, if it's failing to look up  
that host name, it's either because the host doesn't exist in DNS, or  
because of a problem with the DNS resolution path between the host and  
the authoritative name server.

That could be a problem with the stub resolver on the host itself, or  
a problem with its upstream caching resolver, or something upstream  
from there.
