Hello,
We have an old website that connects to a Sybase server using FreeTDS.
Recently, the company hosting the database switched servers (and port),
necessitating a change to the configuration files.
When this happened once before, I figured out that I had to update the
"freetds.conf" file to change the host and port - and get the server admin
to open a port in the firewall. So... we did the same thing this time.
Unfortunately, the connection won't work. I was on the phone with the
database hosting company for a while trying various things, but I'm stumped.
We tried connecting manually using "tsql", and what struck me as odd was the
error message "20004: Read from SQL server failed".
Here's some details:
[root@www ctt]# telnet {domain-name} 4000
Trying {IP-address}...
Connected to {domain-name}.
Escape character is '^]'.
Connection closed by foreign host.
[root@www ctt]# tsql -C
locale is "en_US"
locale charset is "ISO-8859-1"
Compile-time settings (established with the "configure" script):
Version: freetds v0.62.4
MS db-lib source compatibility: no
Sybase binary compatibility: unknown
Thread safety: no
iconv library: yes
TDS version: 5.0
iODBC: no
unixodbc: no
[root@www ctt]# tsql -H {domain-name} -p 4000 -U {username}
locale is "en_US"
locale charset is "ISO-8859-1"
Password: {password}
Msg 20004, Level 9, State 0, Server OpenClient, Line 0
-> Read from SQL server failed.
Msg 20014, Level 9, State 0, Server OpenClient, Line 0
Login incorrect.
There was a problem connecting to the server
They say the new server is the same version and configuration as the one
that was working before (except with the different port), but I can't be
certain, since there definitely seems to be something amiss.
Any ideas? I'd really appreciate any help you could give.
Thanks!!
Mike.
