Description Adam Stiburek 2020-01-05 21:08:35 CET

Description of problem:
1)rdesktop everytime segfaults when connecting to FQDN.
2)rdesktop segfaults for first time if I change some parameter. Does not matter which parameter. Second start with same parameters is OK.

Version-Release number of selected component (if applicable):
rdesktop-1.9.0


Steps to Reproduce:
1) rdesktop everytime segfaults when connecting to FQDN.
1a) segfaults
[user@localhost ~]$ rdesktop w2k12
Autoselecting keyboard map 'cs' from locale
Protocol(warning): Protocol negotiation failed with reason: SSL not allowed by server
Retrying with plain RDP.

[user@localhost ~]$ rdesktop w2k12
Autoselecting keyboard map 'cs' from locale
Protocol(warning): Protocol negotiation failed with reason: SSL not allowed by server

1b) correct execution

[user@localhost ~]$ rdesktop 10.76.8.22
Autoselecting keyboard map 'cs' from locale
Protocol(warning): Protocol negotiation failed with reason: SSL not allowed by server

2) rdesktop segfaults for first time if I change some parameter.
2a) start with previously used parameter is OK

Thank you for this report and the evidence.
Can you say whether this happened only after the update from
 rdesktop-1.8.6-1.mga7 to rdesktop-1.9.0-1.mga7
but was OK before?
If this is so, it would be worth you downgrading the package to the previous version (and not letting it be updated).

Assigning to Stig as the active rdesktop maintainer.

After uninstall 1.9.0 I see rdesktop-1.8.5-1.mga7 only in repo.
With this version I can't connect at all.

[user@localhost ~]$ rdesktop w2k12.linuxbox.cz
Autoselected keyboard map en-us
Failed to negotiate protocol, retrying with plain RDP.

Autoselected keyboard map en-us

It seems to be fixed bug.

Hi bug reporter and hi assignee and others involved,

Please reopen this bug report if it is still valid for Mageia 8 or 9(cauldron), and change "Version:" in the upper left of this report accordingly.

This report is being closed as OLD because it was filed against Mageia 7, for which  support ended on June 30th 2021.

Thanks,
Marja
