If the ELB node does not receive the SYN-ACK packet within the timeout duration, the backend server is declared unhealthy. Then, the ELB node sends an RST packet to the backend server to terminate the TCP connection. If the ELB node receives the SYN-ACK packet from the backend server wit...
Format:tcp-flag{ack|established|fin|psh|rst|syn|urg}* When the TCP protocol is specified in an advanced ACL, the device filters packets based on the TCP flag. A TCP packet header contains six flag bits: URG(100000): indicates that the Urgent pointer field is significant. ...

What does operation in progress mean? What operation? 2. #define EAGAIN 11 /* Try again */ This one is pretty self evident, and I understand that the message should be resent, but does anyone know why I would see this? 3. #define EIO 5 /* I/O error */ IO error I get, but ...
continuous service at the peak expected performance level. Disk reliability depends on the disks installed in the NAS; high-quality SAS disks can offer excellent error-correction and enormous mean time between failure figures, but all disk choices should include a replacement plan. Finally, the NAS...
Overview: TCPing is a tool that pings a port by establishing a TCP connection, much like how ICMP ping checks the availability of a host. It is commonly used for testing port reachability in cases where ICMP is blocked. Use Case: Checking port availability, particularly when ICMP ping is bl...

For example, a TCP end receives a packet for which there is no connection. The receiving side will send a TCP RST to the remote to close the connection and again set up if required. The other ends send the TCP RST Ack. In contrast to the FIN, RST, and RST, Ack immediately closes ...
Please join me in a moment of annoyance that L sometimes mean smallest and sometimes biggest. Within Work Intervals (duration of a single intense bout), the options are short, medium, long, very very short (SIT) (10-30s) and itty bitty (RST) (10s). MICT stands for “moderate intensity...
