Local fix
Problem summary
Users Affected: All SFTP Client Users Problem Description: SFTP Client Begin Sessionm Service takes long time apprx 30 secs to complete We saw the issue becuase of DNS reverse lookup operation which was going for the HotstKeyValidation for Maveric while exchanging the Key Platforms Affected: All
Problem conclusion
SFTP slowness is seen during DNS reverse lookup operation Resolution Summary: Reverse lookup operation from Address to IP conversion was a costly operation which was slowing down the SFTP begin session. Modified to go for DNS lookup by passing the IP instead of Hostname, with this reverse DNS lookup does not take place, which can again improve the performance. Performance improved from 30s to min of 2s in the customer system. Tested SFTP communication with both IP and Hostname configured on the profile.. It is working with Internal and external perimeter servers configured. Delivered In: 5020500
