If it is not possible then the 5433 port will be used. There is an attempt to cast the port value to a Short Type in a “loadPreonnectSettings” method. You need to find the use of a default port “HPE Vertica” in a text editor, it might be able to understand the substance of the problem with the changing 55555 port into 5433. Once completed, there will be decompiled source files. For simple analysis a standard decompiling without flags is suitable. It supports a lot of options for decompiling of Java applications. A “ fernflower” software is good for this task.

It’s possible to try decompiling a driver (.jar) and explore what happens before the connection. To communicate with DBMS Dbeaver uses JDBS and uploads a 6.1.2. It can be assumed that the program sets a wrong port at once. That is strange but here we have a number 5433 in the stack (15 and 39 bytes), which is a default port of DBMS “Vertica”. You need to click “Test Connection” again, but with 55555 port. But what if we indicate the number 55555 as a port? In theory, “03” and “D9” bytes should be placed on the top of the stack. “D2” and “04” bytes in the “Big Endian” format are our number 1234. These instructions set the value into an EAX register from a top of the stack by offset to “arg_0”. If you set the 1234 port and click on “Test connection”, then debugging stops on the breakpoint.įirst, you can notice that the function takes the value via stack. Then, you need to set a breakpoint on “htons” function call. You need to find an import of “ws2_32.d” module and open a list of the functions. “WinAPI” version of “htons” function is in “ws2_32.dll”. To convert a two-byte number (for example, a TCP port) it is possible to use “ htons” functions. To convert Endianness, applications often use a set of functions “host to TCP/IP network” from a NetWare API.

Which port was an attempt to connect to, indeed? It is possible to run an IDA Pro tool and connect to a DBeaver process. In this case, the connection failed on the specified port 1234. However, while entering a short number (1234), there is no such problem.

Under a “Reason” line you can see that it failed to connect to the 5433 port, also there was a report that the client was going to connect to the 55555 port. If you enter a non-standard port, for example, 55555, the tool tries to connect to the default port 5433, anyway. When connecting to a Vertica database through a DBeaver application a problem was detected (ce-4.2.2).
