Summary: NetTerm locks up
Product: Wine
Version: unspecified
Platform: x86
URL: http://www.securenetterm.com/pub/nt325405.exe
OS/Version: Linux
Status: UNCONFIRMED
Keywords: download
Severity: normal
Priority: P2
Component: -unknown
AssignedTo: wine-bugs at winehq.org
ReportedBy: nerv at dawncrow.de
CC: support at securenetterm.com
This is a Bug discussed in Bug 11621 but not belonging there.
Summary:
> As the author of NetTerm, SecureNetTerm, SNetTerm and SecureFTP, I am seeing
> the same problem with NetTerm that I see with Putty as it relates to the telnet
> connection problem.
>
> Our SNetTerm product, as well as the Microsoft telnet.exe DOES NOT have this
> issue.
>
> Is there been any additional information on this issue that would help us get
> this resolved? Where to look? Anytime we can test in the winsock area to help
> resolve the issue?
> I am not sure that this is all that is going on. Our NetTerm product DOES NOT
> send a SIOCATMARK, yet the behavior is much like Putty's. That is, it connects
> to the host ok, then about 2-3 seconds after the connect, it freezes.
>
> Note that it IS NOT a the same place everytime. That is, if I run NetTerm
> without a script, I cannot type fast enough to enter my userid at the Login:
> prompt before the application locks up. However if I use a script, it logs in
> and gets to the command line then locks up.
>
> It appears that some type of timer is involved.
>
> The really strange thing is our SNetTerm product is not affected by the bug at
> all. It does a telnet connect and everything works ok. The same is true for
> the Microsoft telnet.exe program.
> The current version of NetTerm can be downloaded from:
>
> http://www.securenetterm.com/pub/nt325405.exe
>
> and includes a 60 day trial period. If more time is needed, or has been
> downloaded before and trial period has expired, contact me at
> support at securenetterm.com and I will send a new key.
> I found the problem. It is in the telnet tcpip network code, sort of like the
> Putty problem. NetTerm locks up when it issues a winsock recv()call for 1 byte
> with MSG_PEEK in the flags field.
