Description Stephen Murray 2013-08-04 16:02:52 UTC
Description of problem:
After updating krdc to level 4.10.5-1 it no longer brings up a login display to the remote Windows desktop. strace indicates it is looping with EAGAIN.

Version-Release number of selected component (if applicable):
kdenetwork-krdc-4.10.5-1.fc19.x86_64
kdenetwork-krdc-libs-4.10.5-1.fc19.x86_64

How reproducible:
Just run krdc (command line or GUI) and try to connect to a remote Windows system. I happen to be connecting to a pair of Windows 7 Professional 32bit desktops, and a Windows 2008 64bit server.

Steps to Reproduce:
1. Install kdenetwork-krdc-4.10.5-1.fc19.x86_64
2. Run krdc
3.

Actual results:
From "strace krdc", these lines repeat:

poll([{fd=3, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN}, {fd=9, events=POLLIN}, {fd=6, events=POLLIN}, {fd=10, events=POLLIN}, {fd=13, events=POLLIN}, {fd=15, events=POLLIN}], 8, 0) = 0 (Timeout)
recvfrom(6, 0x2508e24, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily unavailable)
recvfrom(6, 0x2508e24, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=3, events=POLLIN}, {fd=7, events=POLLIN}, {fd=8, events=POLLIN}, {fd=9, events=POLLIN}, {fd=6, events=POLLIN}, {fd=10, events=POLLIN}, {fd=13, events=POLLIN}, {fd=15, events=POLLIN}], 8, 0) = 0 (Timeout)
recvfrom(6, 0x2508e24, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily unavailable)
recvfrom(6, 0x2508e24, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily unavailable)

Expected results:
Windows login screen to be displayed.

Additional info:
After downgrading to kdenetwork-krdc-4.10.4-1.fc19.x86_64 krdc works as expected.

Looks like our backport of using freerpd instead of rdesktop has problems. :(

Does manually using xfreerdp work or not for you?

Comment 2 Stephen Murray 2013-08-04 16:48:07 UTC
Yes, xfreerdp is working correctly. It logs me in to the remote Windows desktop.

xfreerdp -u username hostname.fqdn

I've never used xfreerdp before, I'll play around with it too.
