Team , We are connecting to Mainframe System using sftpg3 command , when we connect to Mainframe system most of the time it connects and downalod / upload files without any issues , but for the same command for the same user it doesnt , it just waiting for 10 mins and after than it just shown error message

error: could not connect to `<Mainframe Host Name>'

We have tried with Debug option with 4 level . we could nt able to identify the root cause.

sftpg3 -D 4  -P 269  '<Mainframe Ftp Userid>@<Mainframe Host Name>'

Note : we have the same username , Mainframe Host and command from Other Database servers , where we could able to connect without issues all the time.

We belive there could be problem with Tectia client configuration setings.

when it hangs from debug log , the following line will be the last one.

debug: LOG EVENT (discard,informational): 6200 Broker_tcp_connect, Dst: 'remote ip address', Dst Port: 269, Src Port: 39279, Local username: gzky86

if any one faced similar issue in past ,or Any clue to fix this will help us lot. We were working with last 3 weeks . Thanks Mani

Mani, my issue is a little different from yours. I have been trying to use Tectia 6.0 to connect from my Unix machine to a Mainframe server. Here is what I am using:

/opt/tectia/bin/sftpg3 [ftp_user]@[mainframe_ipaddress]#269

I keep getting a prompt expecting password for [ftp_user]@[mainframe_ipaddress]

Haven't been able to find a solution for this lately. Any clues! What am I doing wrong here?

Hi, can you enter a separate question for this?

Hi, This sounds like the client is not able to reach the remote server and is just timing out. Are you able to reach the server from the same host using other tools? Like ping, traceroute or telnet?

Try running telnet against the server port, such as:

 telnet <Mainframe Host Name> 269

If the server is reachable this should print out the server version string.
