The serctl script has problems on a standard Solaris 8 Install: # serctl ul add 1000 sip:1000@10.10.10.10 grep: illegal option -- E Usage: grep -hblcnsviw pattern file . . . sip:1000@10.10.10.10 is not a valid URI # It turns out that the normal "grep" command on Solaris does not include the "-E" option. You have to use /usr/xpg4/bin/grep instead. I modified the line: check_uri() { # echo "$1" | grep -E "^sip:([a-zA-Z0-9_]+@)?.*\..*" echo "$1" | /usr/xpg4/bin/grep -E "^sip:([a-zA-Z0-9_]+@)?.*\..*" and it seems to be working ok. Just though other Solaris users might want to know. Regards, Ricardo
