Maximum number of processes

The same command exists under Solaris root@root # ulimit -a core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited open files (-n) 32768 pipe size (512 […]

No way I want to make the same mistakes again

To avoid stepping on the same rake again and to fix the issue described in this post, I came out with a simple expect script to save current configuration of Qlogic Sanbox switches. #!/usr/local/bin/expect -f set switches “switch1 switch2” set user {user} set pass {pass} set ftp_user {ftp_user} set ftp_pass {ftp_pass} set timeout 10 log_user […]
